Configuring the ATS Network Management Interface
54 InfraStruXure Power Generation System
DHCP. Use an RFC2131/RFC2132-compliant DHCP server to configure the TCP/IP settings for the
ATS.
1. The ATS sends out a DHCP request with the following identifiers:
– A Vendor Class Identifier (APC, by default)
– A Client Identifier (the ATS’s MAC address value, by default)
– A User Class Identifier (identification of the ATS’s application firmware, by default)
2. A properly configured DHCP server responds with a DHCP offer that includes all of the
settings the ATS needs for network communication. The DHCP offer also includes the Vendor
Specific Information option (DHCP option 43). By default, the ATS 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 summarizes ATS communication with a DHCP server. For more detailed
information about how a DHCP server is used to configure network settings for an ATS,
refer to “DHCP Configuration” in the InfraStruXure Power Generation System’s on-
line Network Management User’s Guide.
Refer to 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 55.
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 55).
