Quick Configuration
DHCP. You can use a RFC2131/RFC2132-compliant DHCP server to
configure the TCP/IP settings for the unit.

This section briefly summarizes the unit communication with
a DHCP server. For more detail about how a DHCP server is
used to configure the network settings for a unit, see “DHCP
Configuration” in the Environmental Management System
Users’ Guide.
1. A unit 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 unit’s MAC address value)
– A User Class Identifier (by default, the identification of the unit’s
application firmware)
2. A properly configured DHCP server responds with a DHCP offer
that includes all of the settings that the unit needs for network
communication. The DHCP offer also includes the Vendor Specific
Information option (DHCP option 43). By default, the unit 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 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 15.
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 15.
