Revision 1.1
WebSwitch™ Users Manual
Use DHCP (model XRDI-WS3P only)
This option allows DHCP to be enabled or disabled. If this option is set to
Yes
, WebSwitch™ will wait
for an IP address from a DHCP server each time it is powered. The default setting is
No
(this is
recommended for most installations). If DHCP is set to
Yes
, the Network page must be submitted
and WebSwitch™ must be rebooted before an IP address will be assigned. Once the WebSwitch™
is assigned an IP address by the DHCP, the new IP address can be found through the clients list
kept by the DHCP server. For most instances, this is found on the local gateway or router.
Brief notes about DHCP
All devices on an IP network require an IP address. This is a unique address that identifies each
device on the network. DHCP (Dynamic Host Control Protocol) is a mechanism that automatically
assigns an IP address to a computer (or other devices) when it is connected to a network. This
eliminates the need to manually enter the IP address. When a computer is connected to the
network, another device on the network called a DHCP server detects the presence of the computer
and dynamically assigns the IP address to that computer. On many small networks, the DHCP
server is built into the router.
DHCP works well for "client" devices such as computers, but is not ideal for servers. This is because
servers usually don't initiate communications with other devices, but rather they wait for a request
from "clients." To make this request, the client must know the IP address of the server. If a server
gets its IP address dynamically, the IP address may not always be the same so client devices may
not be able to find the server. For this reason, servers usually use an IP address that is fixed and
does not change. The WebSwitch™ is a server and manual IP address assignment is usually
recommended.
IP Address
Enter the IP address for WebSwitch™ in this field. The IP address is specific to the network where
WebSwitch™ will be installed, and must be obtained from the network administrator. For more
information on IP addresses and remotely accessing WebSwitch™ over the Internet, see
Appendix
C: Remote Access
. The default setting for this field is
192.168.1.2.
Subnet Mask
The subnet mask defines the size of the local network. This must be obtained from the network
administrator. For additional information about sub-netting and IP networking, many tutorials are
available on the Internet. The default setting for this field is
255.255.255.0
.
Gateway
This specifies the IP address of the gateway router. This must be obtained from the network
administrator. The default setting for this field is
192.168.1.1
.
Preferred DNS Server
The IP address of the Primary DNS server is specified here. When DNS services are required, this
is the address that will be used. The default setting for this field is
192.168.1.1
.
Note: This field is only required when the following options are used
━
Remote Services (when server is specified by name and not IP address).
━
Sync time clock with remote NTP server (when server name is specified by name and not IP
address).
━
Mail Server (when server name is specified by name and not IP address).
