Switched Rack PDU Installation and Quick-Start Manual 9
DHCP. You can use a RFC2131/RFC2132-compliant DHCP server to
configure the TCP/IP settings for the Switched Rack PDU.
1. The Switched Rack PDU sends a DHCP request that uses the
following to identify itself:
– Vendor Class Identifier (APC by default)
– Client Identifier (by default, the Switched Rack PDU’s MAC
address value)
– User Class Identifier (by default, the identification of the
Switched Rack PDU’s application firmware)
2. A properly configured DHCP server responds with a DHCP offer
that includes all of the settings that the Switched Rack PDU needs
for network communication. The DHCP offer also includes the
Vendor Specific Information option (DHCP option 43). By default,
the Switched 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 disable the APC cookie requirement, see “Local access
to the control console” on page 10. To change the control
