DHCP. You can use a RFC2131/RFC2132-

compliant DHCP server to configure the

TCP/IP settings for the

PDU.

1. The

PDU sends a DHCP request that uses the

following to identify itself:

Vendor Class Identifier (APC by default)

Client Identifier (by default, the PDU’s

MAC address)

User Class Identifier (by default, the

identification of the

PDU’s application

firmware)

2. A properly configured DHCP server responds

with a DHCP offer that includes all of the

settings that the

PDU needs for network

communication. The DHCP offer also includes

the Vendor Specific Information option

(DHCP option 43). By default, the

PDU

ignores DHCP offers that do not encapsulate

the APC cookie in the Vendor Specific

Information option using the following

hexidecimal format:

Option 43 = 01 04 31 41 50 43

where

The first byte (01) is the code

The second byte (04) is the length

The remaining bytes (31 41 50 43) are

the APC cookie

This section summarizes the PDU

communication with a DHCP server.

For more detail about how a DHCP

server is used to configure the network

settings for the

PDU, see “DHCP

Configuration Settings” in the User’s

Guide.

See your DHCP server documentation

to add code to the Vendor Specific

Information option.

You can use a local computer to disable

the APC cookie requirement. To use a

local computer, see “Local access to

the control console” on page 12. To

change the control console’s DHCP

Cookie Is setting, an Advanced option

in the TCP/IP menu, use Telnet or

another remote accessing method. To

access the control console, see

“Remote access to the control console”

on page 13.
