Troubleshooting Procedures

4-22

Completing the Hot Swap

To complete the hot swap of the Remote Access Concentrator:

1.

Verify that the jumper settings on the replacement module
are the same as the settings on the original module.

2.

Use the procedures outlined in

Chapter 2

to insert the

replacement module into the System 5000 chassis.

3.

Boot the replacement Remote Access Concentrator.

The saved EEPROM information is read by the Remote Access
Concentrator at boot time only in a hot swap situation. The
Remote Access Concentrator compares the “board serial
number” field (in the supervisory module nonvolatile memory)
against its internal serial number. After loading the operational
image, the initialization process sets up the network interface
and then reads the params.n.n.n.n file from the host server, and
places it in local memory. The EEPROM file contents are
decrypted and written to the EEPROM. The buffer containing
the files is then discarded. This process may take several
minutes to complete.

4.

If applicable, obtain a new LAT key and enter it.
