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

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.

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.

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
Download from Www.Somanuals.com. All Manuals Search And Download.
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.

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
Download from Www.Somanuals.com. All Manuals Search And Download.
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.

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.

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.
NC Normally Closed —Refers to a contact switch that is
normally closed.
