This section summarizes the Rack ATS communication with a DHCP server. For more detail about how a DHCP server is used to configure the network settings for the Rack ATS, see “DHCP Configuration” in the User’s Guide.
1.The Rack ATS sends a DHCP request that uses the following to identify itself:
–Vendor Class Identifier (APC by default)
–Client Identifier (by default, the MAC address of the Rack ATS)
–User Class Identifier (by default, the identification of the application firmware used by the Rack ATS)
2.A properly configured DHCP server responds with a DHCP offer that includes all of the settings that the Rack ATS needs for network communication. The DHCP offer also includes the Vendor Specific Information option (DHCP option 43). By default, the Rack ATS 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 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. To access the control console, see “Remote access to the control console” on page 9.
Local access to the control console
You can use a local computer to connect to the ATS to access the control console.
1.Select a serial port at the local computer and disable any service that uses that port.
2.Use the communication cable to connect the selected port to the serial port on the front panel of the ATS.
3.Run a terminal program (such as HyperTerminal®) and configure the selected port for 9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control. Save the changes.
4.Press ENTER to display the User Name prompt.
5.Use apc for the user name and password.
6.See “Control console” on page 10 to finish the configuration.
