Setting Description
Manual The IP address, subnet mask, and default gateway must be configured manually. Click Next>>, and
enter the new values.
BOOTP A BOOTP server provides the TCP/IP settings. At 32-second intervals, the PDU requests network
assignment from any BOOTP server:
• If it receives a valid response, it starts the network services.
• If it finds a BOOTP server, but a request to that server fails or times out, the PDU stops requesting
network settings until it is restarted.
• By default, if previously configured network settings exist, and it 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 At 32-second intervals, the PDU requests network assignment from any DHCP server. By default,
the number of retries is unlimited.
• If it receives a valid response, by default it requires the APC cookie from the DHCP server in order
to accept the lease and start the network services.
• If it finds a DHCP server, but the request to that server fails or times out, it stops requesting
network settings until it is restarted.
To change these values, click Next>> for the DHCP Configuration page
1
:
• Require vendor specific cookie to accept DHCP Address: Disable or enable the requirement that
the DHCP server provide the APC cookie.
• 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.
DHCP &
BOOTP
The default setting. The PDU tries to obtain its TCP/IP settings from a BOOTP server first, and then,
if it cannot discover a BOOTP server, from a DHCP server. If it obtains its TCP/IP settings from
either server, it switches this setting to BOOTP or DHCP, depending on the type of server that
supplied the TCP/IP settings to the PDU.
Click Next>> to configure the same settings that are on the BOOTP Configuration and DHCP
Configuration pages
1
and to specify that the DHCP and BOOTP setting be retained after either
type of server provides the TCP/IP values.
1. 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 PDU, which uniquely identifies it on the local area network (LAN)
•User Class: The name of the application firmware module
