2.5 DHCP and IP Configuration
Each switch must be designated an IP address before it can be managed
from web browser. Basically, the switches provide two methods for IP
configuration:
1. DHCP mode
The switch requests a dynamic IP address from the first discovered
DHCP server in the network when boot up. In general, the assigned
IP can be monitored in the client list on the DHCP server. The model
name and MAC address of the switch is referred as the DHCP client
ID. If no DHCP server is discovered after a retry period for about 40
seconds, the pre-configured static IP is used automatically.
2. Static IP mode
One pre-configured IP address is used when DHCP mode is disabled
or when DHCP mode is enabled and no DHCP server is available.
The static IP can be configured through management interface. Each
switch comes with one identical factory default IP upon device
reception.
It is important to record the MAC address and location where it is in-
stalled for each switch. It would help in tracing the IP and device map-
ping.
2.6 Push Button IP SW
One push button IP SW located on rear panel is used to disable DHCP mode
and restore static IP back to factory default value. It is useful when you do
not recall your static IP setting and DHCP solution is not available.
To make the function work, push the SW and keep for at least 5 seconds
when the switch is powered on to be boot up.
