Completing The Hot Swap - Bay Networks 5393 Hardware Installation Manual

Completing the Hot Swap

To complete the hot swap of the Remote Annex:
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 Annex.
The saved EEPROM information is read by the Remote Annex at
boot time only in a hot swap situation. The Remote Annex
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 Set the configuration parameters acp_key, vcli_password, password,
and the port parameter port_password to the same values as the
original Remote Annex.
Set these parameters manually through the admin or the na
utility, or through some SNMP application, since they cannot be
saved and restored by the na write and na read commands or by
the SNMP get and set commands.
You can set values by using the na utility on a UNIX host, using
SNMP (if UNIX is configured for it) or enter Monitor Mode from
the Remote Annex's service port terminal, become a superuser,
and use the admin command.
5 If applicable, obtain new option keys and enter them.
