Introduction  
The ePowerSwitch is a network-manageable, intelligent power  
control unit designed to provide control of power for up to eight  
electrical devices in Internet age.  
ePowerSwitch Features  
The ePowerSwitch System features:  
?? Internet ready — Individually control each of eight  
outlets using a web browser, telnet, or a terminal program  
?? Remotely and individually reboot hung servers  
?? If network hung, you can use telephone to control the  
ePowerSwitch to shutdown or reboot locked up  
devices or servers.  
?? Sequentially apply power to equipment that is plugged  
into the ePowerSwitch.  
?? Multiple OS support—As long as there is Network  
Management software present.  
?? Remote setup support— Once an IP address is assigned,  
the rest can be setup remotely through telnet commands.  
?? Easy USB port setup—In addition to regular serial port  
setup support, this adapter also has a USB setup feature  
and is the preferred method for initial setup of this card.  
(Requires Windows 98)  
?? Remote Control—Turns each receptacle on/off when the  
NMS sends the proper command.  
?? NMSs To Receive Alarms—These traps (unsolicited  
messages) inform you about the power condition of the  
power outlets.  
1
 
2
?? Works with all major NMSs on Ethernet—  
ePowerSwitch System works with the most widely used  
Network Management Systems: HP Open View, Sun  
NetManager, IBM NetView, and many more.  
?? Remote Firmware upgrade support - The  
ePowerSwitch System supports firmware upgrade through  
TFTP server remotely. A serial upgrade method is  
available too.  
?? Ring On or Reset adapter  
Status LEDs  
– Three LED indicators:  
Red LED – indicates the ON/OFF status for each of the rear  
output socket respectively from A to H  
Green LED – indicates the Internet (remote) control or non  
Internet (front panel) control status of the corresponding  
socket. You may change this status by pressing and holding  
the button for 3 seconds till the LED blinking then release the  
button.  
Yellow LED – indicates the number of ePowerSwitch  
connected to NIC. The first one always has NIC built-in. The  
rest of the ePowerSwitch doesn’t have NIC (device  
2,3,4,…up to 16). They are connected through iLink port via  
iLink cable line.  
Switch  
Master Switch – controls the power for the entire unit.  
2
 
On/Off Buttons – control for each of the corresponding rear  
socket. Press and hold for 3 seconds to setup up the  
Remote/local control for each of the corresponding rear  
socket. If you installed an optional NT card inside the  
ePowerSwitch, there is a delay time for the corresponding  
outlet of the NT card to off the power for the safe shutdown  
functionality. The default delay time is set up as 3 minutes.  
RJ 11 Jacks  
iLink Port – Daisy chain to the another ePowerSwitch client  
(without NIC).  
Ring On/Reset Port – Connect to telephone line for  
telephone On/Reset control.

IP Setup  
This section describes the IP set up & configuration of the  
ePowerSwitch System when you connect it to the network.  
There are four different ways to setup ePowerSwitch.  
1. Setup IP address via Ethernet port using the ARP  
command (first time only), then use a Web browser to  
setup all the parameters. This is the easiest way to  
setup.  
2. Setup via serial RS232 port using terminal software,  
e.g. Windows HyperTerminal.  
3. Setup via USB port using ePowerSwitch USBSetup  
software (USBSetup software included).  
4. Setup IP address by using ARP command (first time  
only), then use telnet command to do the rest of the  
setup. The setup interface is the same as serial RS232  
port setup.  
5. Setup IP address via Ethernet cascaded cable.  
1.Setup via Ethernet port  
Before setup you need:  
1. IP address: Get a valid IP address from administrator.  
2. MAC address: Find MAC address on the front panel of  
the Web Card.  
3. Default password: admin  
6
 
The following steps guide you in connecting the ePowerSwitch  
System through the Ethernet port  
1. Connect the Ethernet port to the network with the Ethernet  
cable.  
2. Using the following settings in the text mode:  
c:\>arp –s 216.87.151.196 52-54-4c-19-ad-  
90  
??216.87.151.196 is the IP address  
??52-54-4c-19-ad-90 is the MAC  
address.  
Use ARP command to setup IP address only for the  
first time and the IP address is temporarily.  
3. Use a Web browserto enter in and configure all  
ePowerSwitch network parameters with the IP address you  
setup by ARP command.  
Use Web browser to set IP, gateway and subnet  
1. Select Network” in the SERVER category.  
2. Fill out the blank and click “save” button.  
3. Select “Save&Restart”, then click “Save and Restart”  
button to save network information into Web Card and  
reboot it.  
4. Web Card needs about 30 seconds to reboot. Then IP setup  
procedure is done. ePowerSwitch works now.

2. Setup via serial port  
Before setup you need:  
1. IP address: Get a valid IP address from administrator.  
2. RS232 Cable.(enclose)  
3. Dumb terminal software: ex: HyperTerminal in the  
win95/98, NT, Win2000.  
4. Default password: admin

10  
3. Press OK if you have the Windows  
Communications screen or accept your  
communication settings in the terminal emulation  
package. The terminal/PC is now configured to  
communicate with the ePowerSwitch.  
4. Approximately three seconds after you turn on  
AC power, the terminal displays “Check u-  
dram…”. Within 5 seconds, press “/” when  
you see “Waiting five seconds…” to enter  
console configuration.  
You are now ready to configure the ePowerSwitch. Refer to  
the following Configuration section for a more detailed  
discussion.  
10  
 
Note:  
The telnet setup procedure is the same as the serial  
setup.  
When the configuration is completed, remember to save and  
restart.  
Serial or Telnet Configuration  
ePowerSwitch System is temporarily connected to a PC with a  
terminal emulation package or through telnet connection. The  
advantage of telnet configuration over serial port configuration is  
telnet operation can be done anytime, but serial configuration  
has a short five seconds login window when the NIC Web  
Card starts up.  
Approximately three seconds after you turn on the power for  
ePowerSwitch, the NIC card displays “Check u-dram…”  
Press “/” when you see “Waiting five seconds…” to enter  
console configuration.  
You are now ready to configure the ePowerSwitch.  
Enter the user name and password.  
Use CTRL-W to move up, CTRL-Z to move down. From this  
menu you can select to enter the IP address, Gateway address,  
and MIB system group; you can set trap receivers, display  
settings; reset the settings to default values; save the new values  
and exit the program, and exit without saving.  
Use terminal to set IP, gateway and subnet  
To set the IP address and Gateway address, select the first  
item.

Figure 4 - IP Address for the ePowerSwitch System and  
More  
NOTE: The minimum requirement to operate ePowerSwitch  
Systemis to set the IP address.  
If you want to return to the Main Menu, press Esc key.  
For more information on IP addresses and net masks, see the  
Reference section of the Appendix in this manual.  
The ISP setup is for dial-up connection.  
12  
 
To Save and Exit  
If you are satisfied with your configurations, be sure to save  
them and exit.  
3. Setup via USB port  
Before setup you need:  
1. IP address: Get a valid IP address from administrator.  
2. USB Cable. (Enclose)  
3. USB driver and USBSetup file. (Enclose in the disk)  
1. Connect the ePowerSwitch to a Windows 98 PC through  
an USB cable. If the PC prompts for a new driver, insert  
the floppy provided. Uncheck update Windows 98 check  
box. It will copy the proper driver from the floppy. Follow  
the instructions. The new USB device will be recognized  
when the driver is properly installed. No system start up is  
required. See the picture below. Sometimes it takes longer  
13  
 
14  
to see the device because the ePowerSwitch takes about  
30 seconds to boot.  
2. The “USB-interface power device” name must appear in  
the System Properties dialog box before you run the USB  
setup software.  
14  
 
3. USB setup is straightforward once the PC has successfully  
detected USB device. See the following figure.  
You need to run Device | Update & Restart before closing  
4.Telnet Options  
You can also Telnet to the IP address of the ePowerSwitch  
System after it has been installed on your network. Once you  
have successfully established a Telnet connection with the  
15  
 
16  
adapter you may access the configuration menu as if you were  
directly attached to it via the configuration port.  
Moving cursor in telnet session is tricky. You need to select  
VT100 cursor which is under Terminal | Preferences |  
VT100 Arrows. After this setup, moving around menu system  
is actually easier than in console setup mode.  
Note:  
You must have previously configured at least the IP  
address and router information locally in order to  
successfully make a Telnet connection.  
5.Setup via Ethernet Cascaded Cable  
Before setup you need:  
1. IP address: Get a valid IP address from administrator.  
2. Ethernet Cascaded Cable. (Not Enclose)  
The following steps guide you in connecting the ePowerSwitch  
System through the Ethernet port  
1. Assign your PC’s IP address to dedicated IP address -  
216.87.151.1  
2. Connect the ePowerSwitch’s Ethernet port and PC’s  
network port with Ethernet cascaded cable.  
3. Enter ePowerSwitch web default IP address-  
216.87.151.196 by web browser, then Use Web browser to  
set IP, gateway and subnet.  
16  
 
Configuration  
PPP Configuration  
PPP connection is useful if it is not possible to make a  
direct network connection to the ePowerSwitch. Again the  
external modem is needed to connect to the front serial port of  
the NIC Web card of the ePowerSwitch.  
Fill in the blank as above in your web and save.  
17  
 
18  
Remote operation procedure  
1. The remote user may hang up after three rings when dial  
in.  
2. Based on the content of the PPP configuration,  
ePowerSwitch will then automatically dial up to the  
designated ISP and send the e-mail to the  
designated e-mail address with the assigned IP  
address from ISP.  
3. User may browse and control ePowerSwitch with this  
dynamic IP  
4. Check the disconnection on the bottom of the PPP  
configuration page after work.  
18  
 
User Management  
Administrators can assign the maximum of 4 users to control the  
outlet.  
19  
 
20  
Software Update  
This is the place you can upgrade the firmware when it is  
available or bug fix.  
20  
 
ePowerSwitch Configuration  
Each outlet can be individually programmed to enable ring  
On/Off or reset. Power resume delay is convenient for  
sequential startup. Name of each outlet can be labeled to  
whatever you like it to be called. For example, server1, DSL  
modem, webserver1, etc. Since 16 ePowerSwitches can be  
daisy chained together to share one NIC, so each unit can be  
individually named. The last item “Enable waiting device  
shutdown” is dedicated to Microsoft Windows NT (4 and  
2000, workstation and server) to have a safe shutdown. If you  
installed an optional NT card inside the ePowerSwitch, there is  
a delay time for the corresponding outlet of the NT card to off  
the power for the safe shutdown functionality. The default delay  
time is set up as 5 minutes.  
21  
 
22  
To enable this safe shutdown function, in both NT and WIN  
2000, you need to have three setting for the UPS to configure  
it.  
Connect the communication port on the rear of ePowerSwitch  
to NT or WIN 2000 server with the PC Communication cable.  
Connect the corresponding outlet on the rear of ePowerSwitch  
to the NT or WIN 2000 server with the PC input power cord.  
Check the corresponding box of safe waiting device shutdown  
in ePowerSwitch configuration page to enable this function.  
22  
 
Scheduled shutdown  
Scheduled shutdown can be accomplished here. Be careful  
with which outlet you are working.  
23  
 
24  
Verify The ePowerSwitch Operation  
1. After you complete all configuration settings and connect the  
ePowerSwitch System to the network, check the LINK status.  
Power and Link lights should be on all the times. Collision  
light turns on occasionally.  
2. PING the ePowerSwitch System. Issue a PING command  
from the NMS (Network Management Station).  
a) If you do not get a response, check the card ’s  
network connection and IP address.  
3. Test the adapter with an NMS. Perform a “get” and a  
“set.”  
a) If the get or set commands fail, check the  
ePowerSwitch System access controls. The manager  
must have read permission to execute a get  
command successfully and read/write permission to  
execute a set command successfully.  
(See Configuring the NMS section for a detailed discussion.)  
Your ePowerSwitch is now installed and  
completely functional.  
24  
 
Upgrade Firmware  
TFTP Upgrade  
With a Web browser, click on “Software upgrade”, input TFTP  
server’s IP address and go. Make sure that the firmware file  
(For example: ups.bin) is located in the default directory of the  
TFTP server.  
RS232 Serial Port Console Upgrade  
The following steps guide you in connecting the ePowerSwitch  
System through the serial port  
1. Connect the RS232 port to a dumb terminal/PC with a null  
serial cable.  
2. Power on the NIC card of the ePowerSwitch;  
? You have to reconfig all setting in ePowerSwitch after the  
upgrade process has been completed successfully because all  
25  
 
26  
the user data are lost.  
26  
 
Telephone Interface  
You must have the optional phone card installed inside  
the ePowerSwitch Server for all the functions discussed  
here. Please check the dealer for the detail information.  
Telephone access interface  
1. Dial up the ePowerSwitch.  
2. After three sequence rings, the ePowerSwitch will respond  
by sending out 3 short beeps to the caller and waiting for  
user to enter password.  
3. User enters access password. The default password is  
123456789#.  
4. The ePowerSwitch will send out  
a. 3 short beep to confirm successful login.  
b. A long beep to deny access.  
5. Once logged in, remote user can change ID Address:  
333XXxx# is Change ID Address Command.  
XX is Current Address, xx is Change ID Address.  
Eg, 3330001# change ePowerSwitch ID from 0 to 1.  
The default ID address for ePowerSwitch is 0.  
The valid ID address for ePowerSwitch is 1, 2…16. The ID  
address set for ePowerSwitch in daisy chain needs to be  
different.  
Note: If you had setup ePowerSwitch ID from by web, you  
do not need to change ID here.  
6. Once logged in, remote user can punch in 4 digits  
27

Every command must add “#” in the end.  
Eg, 0111# turn on ePowerSwitch01, outlet A,  
0120# turn off ePowerSwitch01, outlet B,  
0142# to reset ePowerSwitch01, outlet D (turn off  
immediately, and on after 10 seconds)  
Remote user may punch in 8 digits to delay reset, on or off.  
Eg,  
02813600# means turn ePowerSwitch02 outlet H on after  
3600 minutes.  
02803600# means turn ePowerSwitch02 outlet H off after  
3600 minutes.  
02823600# means reset ePowerSwitch02 outlet H after  
3600 minutes.  
Use combination of 0111XXXX# and 0112XXXX# to get  
different delay for reset, or create a longer command.  
XXXX max value is 9999, which is about 166 hours, or  
6.94 days.  
7. The ePowerSwitch will acknowledge received commands  
by issuing 2 short beeps otherwise a long beep indicate  
failure or not recognizable.  
8. Change password. The default password is 123456789.  
User has to enter previous password in order to change  
password.  
28  
 
9. User enter 888XXX…..# or whatever previous password,  
then ePowerSwitch responds with three short beeps  
acknowledge access granted. Then user enter new  
password as following:  
888XXXXXXXXXX#, and ePowerSwitch acknowledge 2  
short beeps, sounds like “what?” and user input  
888XXXXXXXXXX# the second time to re-confirm, and  
ePowerSwitch acknowledge 4 short beeps, indicating  
password change completed.  
10. Hang up to close access.  
11. Each command string should be entered within 20 seconds,  
the ePowerSwitch in a waiting loop to receive command.  
After 180 seconds without user input, the device will logout  
user.  
12. “000#” key force to logout.  
13. *” key cancel keyin error .  
14. User interface use minutes as unit.

Appendix  
This appendix has three sections: Reference, Glossary, and  
Troubleshooting.  
Reference  
This section discusses Communities, IP Addresses, Sub net  
masking, and routers/gateways.  
Communities  
A community is a string of printable ASCII characters that  
identifies a user group with the same access privileges. For  
example, a common community name is “public.”  
For security purposes, the SNMP agent validates requests  
before responding. The agent can be configured so that only  
trap managers that are members of a community can send  
requests and receive responses from a particular community.  
This prevents unauthorized managers from viewing or changing  
the configuration of a device.  
IP Addresses  
Every device on an internetwork must be assigned a unique IP  
(Internet Protocol) address. An IP address is a 32-bit value  
comprised of a network ID and a host ID. The network ID  
identifies the logical network to which a particular device  
belongs. The host ID identifies the particular device within the  
logical network. IP addresses distinguish devices on an  
internetwork from one another so that IP packets are properly  
transmitted.  
30  
 
IP addresses appear in dotted decimal (rather than in binary)  
notation. Dotted decimal notation divides the 32-bit value into  
four 8-bit groups, or octets, and separates each octet with a  
period. For example, 199.217.132.1 is an IP address in dotted  
decimal notation.  
To accommodate networks of different sizes, the IP address  
has three divisions—Classes A for large, B for medium, and C  
for small. The difference among the network classes is the  
number of octets reserved for the network ID and the number  
of octets reserved for the host ID.  
Class

IGMP multicast and other special protocols  
Subnetting and Subnet Masks  
Subnetting divides a network address into subnetwork  
addresses to accommodate more than one physical network on  
a logical network.  
For example: A Class B company has 100 LANs (Local Area  
Networks) with 100 to 200 nodes on each LAN. To classify  
the nodes by its LANs on one main network, this company  
31  
 
32  
segments the network address into 100 subnetwork addresses.  
(If the Class B network address is 150.1.x.x, the address can  
be segmented further from 150.1.1.x through 150.1.100.x.)  
A subnet mask is a 32-bit value that distinguishes the network  
ID from the host ID for different subnetworks on the same  
logical network. Like IP addresses, subnet masks consist of  
four octets in dotted decimal notation. You can use subnet  
masks to route and filter the transmission of IP packets among  
your subnetworks. The value “255” is assigned to octets that  
belong to the network ID, and the value “0” is assigned to  
octets that belong to the host ID.  
For the example above, if you want all the devices on the  
subnetworks to receive each other’s IP packets, set the subnet  
mask to 255.255.0.0. If you want the devices on a single  
subnetwork only to receive IP packets from other devices on its  
own subnetwork, set the subnet mask to 255.255.255.0 for the  
devices on that subnetwork.  
Subnet Mask  
Routing and Filtering  
0.0.0.0  
IP packets are transmitted to all  
devices.  
IP packets are only transmitted to  
devices whose IP address’s first octet  
255.0.0.0  
matches the sender’s IP address’s first  
octet.  
IP packets are only transmitted to  
devices whose IP address’s first two  
255.255.0.0  
octets match the sender’s IP address’s  
first two octets.  
IP packets are only transmitted to  
devices whose IP address’s first three  
255.255.255.0  
octets match the sender’s IP address’s  
32  
 
first three octets.  
Gateways  
Gateway, also referred to as a router, is any computer with two  
or more network adapters connecting to different physical  
networks. Gateways allow for transmission of IP packets  
among networks on an internetwork.  
33  
 
34  
Glossary  
The Glossary section defines the terms used in the  
ePowerSwitch System -MP environment.  
Agent Implemented SNMP applications in network elements  
(hosts). Agents perform the network management’s  
functions as requested by the network administrator from  
an NMS.  
Dry Closure Input Non-powered contact type inputs—switch, relay contact,  
open-collector.  
Dry Closure Output Form C dry-contact outputs which are common, normally  
open, or normally closed.  
EtherNet Local Area Network technology, originally developed by the  
Xerox Corporation, can link up to 1,024 nodes in a bus  
network. EtherNet provides raw data transfer in a rate of  
10 megabits/sec. with actual throughputs in 2 to 3  
megabits/sec. using a baseband (single-channel)  
communication technique. EtherNet uses carrier sense  
multiple access collision detection (CSMA/CD) that  
prevents network failures when two devices attempt to  
access the network at the same time. LAN hardware  
manufactures use EtherNet protocol; their products may  
not be compatible.  
Gateway A computer that attaches to a number of networks and  
routes packets between them. The packets can be  
different protocols at the higher levels.  
IP Internet Protocol—The TCP/IP standard protocol defines  
the IP datagram as the unit of information passed across a  
network.  
IP Address Internet Protocol Address—A 32-bit address assigned to  
hosts participating in a TCP/IP network. The IP address  
consists of network and host portions. It is assigned to an  
interconnection of a host to a physical network.  
MAC Medium Access Control—The network layer between the  
physical and the datalink layers. Specifically, the physical  
(hardware) address exists in this layer.  
MIB Management Information Base—The database, i.e., set of  
variables maintained by a gateway running SNMP.

Router A computer that manages traffic between different network  
segments or different network topologies. It directs the  
destination IP address. The network media can be  
different, but the higher level protocols must be the same.  
RS-232 A specification for serial communication between data  
communication equipment and computers.  
SNMP Simple Network Management Protocol—A standard protocol  
used to monitor IP hosts, networks, and gateways. SNMP  
defines a set of simple operations that can be performed  
on the OIDs of the MIBs managed by the monitored  
Agents. It employs the UDP/IP transport layer to move  
its object between the Agents and the NMS.  
Sub-Agent A software module that manages specific MIB sub-groups for  
an Agent. They communicate with the Agent using a  
SMUX (multiplexer).

Troubleshooting  
Problem:  
The TES (Terminal Emulation Software) does not display  
anything.  
Solution:  
Make sure the TES’s communication parameters are correct. They  
should be 115200 baud rate, no parity, 8-data bits, and 1 stop bit.  
The cable is a null serial cable.  
PROBLEM: The NMS cannot ping the ePowerSwitch System.  
Solution:  
Make sure the network connection to the ePowerSwitch System is  
good.  
Solution:
