This section summarizes the Rack PDU communication with a DHCP server. For more detail about how a DHCP
See also server is used to configure the network settings for the Rack PDU, see “DHCP Configuration” in the User’s Guide.
1.The Rack PDU sends a DHCP request that uses the following to identify itself:
–Vendor Class Identifier (APC by default)
–Client Identifier (by default, the Rack PDU’s MAC address)
–User Class Identifier (by default, the identification of the Rack PDU’s application firmware)
2.A properly configured DHCP server responds with a DHCP offer that includes all of the settings that the Rack PDU needs for network communication. The DHCP offer also includes the Vendor Specific Information option (DHCP option 43). By default, the Rack 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
See your DHCP server documentation to add code to the Vendor Specific Information option.

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. See “Remote access to the control console” on page 11.
