Communication Configuration
46 40kW InfraStruXure PDU—Operation and Configuration
DHCP. You can use a RFC2131/RFC2132-compliant DHCP server to configure the TCP/IP settings
for the PDU.
1. An InfraStruXure PDU sends out a DHCP request that uses the following to identify itself:
– A Vendor Class Identifier (APC by default)
– A Client Identifier (by default, the PDU’s MAC address value)
– A 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 will ignore 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 cookies

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 a
PDU, see “DHCP Configuration” in the InfraStruXure Power Distribution Unit’s
online Network Management User’s Guide.
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 47.
To change the control console’s DHCP Cookie Is setting, use the Advanced option in
the TCP/IP menu. See “Remote access to the control console” on page 47.
