APC ACRD101 User Manual

For the Network Management Card to use a BOOTP server to configure its TCP/IP settings, it 

must find a properly configured RFC951-compliant BOOTP server.

1. In the BOOTPTAB file of the BOOTP server, enter the MAC address of the Network 

Management Card, the IP address, the subnet mask, default gateway, and an optional bootup file 
name. Look for the MAC address on the display interface (Path: Main > Configure Network) 
or on the label on the back of the Network Management Card.

2. When the Network Management Card reboots, the BOOTP server provides it with the TCP/IP 

settings. 

– If you specified a bootup file name, the Network Management Card attempts to transfer that 

file from the BOOTP server using TFTP or FTP. The Network Management Card assumes all 
settings specified in the bootup file. 

– If you did not specify a bootup file name, you can configure the other settings of the Network 

Management Card remotely through its Web interface or control console; user name and 
password are both apc, by default.

See your BOOTP server documentation to creat a bootup file.

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

the Network Management Card. 

This section summarizes communication between the Network Management Card and a 
DHCP server. For more detail about how a DHCP server can configure the network settings 
for a Network Management Card, see “DHCP Configuration” in the User’s Guide.

1. A Network Management Card 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 MAC address value of the Network Management Card)
– A User Class Identifier (by default, the identification of the application firmware of the 

Network Management Card)

2. A properly configured DHCP server responds with a DHCP offer that includes all of the settings 

that the Network Management Card needs for network communication. The DHCP offer also 
includes the Vendor Specific Information option (DHCP option 43). By default, the Network 
Management Card will ignore DHCP offers that do not encapsulate the APC cookie in the Vendor 
Specific Information option using the following hexadecimal 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 requirement that a DHCP offer include the APC cookie, use the 
DHCP Cookie Is setting in the control console: 
Network>TCP/IP>Boot Mode>DHCP only>Advanced>DHCP Cookie Is.
