Path: Administration > Network > TCP/IP
The TCP/IP option on the left navigation menu, selected by default when you choose Network on the
top menu bar, displays the current IPv4 address, subnet mask, default gateway, MAC address, and boot
mode of the Rack PDU. For information on DHCP and DHCP options, see RFC2131 and RFC2132.
Setting Description
Enable Enable or disable IPv4 with this check box.
Manual Configure IPv4 manually by entering the IP address, subnet mask, and default gateway.
BOOTP A BOOTP server provides the TCP/IP settings. At 32-second intervals, the Rack PDU requests
network assignment from any BOOTP server:
• If the Rack PDU receives a valid response, it starts the network services.
• If the Rack PDU finds a BOOTP server, but a request to that server fails or times out, the Rack
PDU stops requesting network settings until it is restarted.
• By default, if previously configured network settings exist, and the Rack PDU receives no valid
response to five requests (the original and four retries), it uses the previously configured settings
so that it remains accessible.
Click Next>> to access the BOOTP Configuration page to change the number of retries or the
action to take if all retries fail :
1
• Maximum retries: Enter the number of retries that will occur when no valid response is received,
or zero (0) for an unlimited number of retries.
• If retries fail: Select Use prior settings (the default) or Stop BOOTP request.
DHCP The default setting. At 32-second intervals, the Rack PDU requests network assignment from any
DHCP server.
• If the Rack PDU receives a valid response, it does not (as previously) require the APC cookie
from the DHCP server in order to accept the lease and start the network services.
• If the Rack PDU finds a DHCP server, but the request to that server fails or times out, it stops
requesting network settings until it is restarted.
1
• Require vendor specific cookie to accept DHCP Address: By selecting this check box, you can
require the DHCP server to provide a cookie which supplies information to the Rack PDU.

The default values for these three settings on the configuration pages generally do not need to be changed:
•Vendor Class: APC
•Client ID: The MAC address of the Rack PDU, which uniquely identifies it on the local area network (LAN)
•User Class: The name of the application firmware module
