Metered Rack Power Distribution Unit 11

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 value)

– 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 briefly 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” 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. For instructions on using 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 12.
