Preparing for a Hot Swap

The Remote Access Concentrator can be inserted into or removed from
a chassis without interrupting service to other modules within the System
5000 hub. This ability is referred to as "hot swapping."
The Remote Access Concentrator holds 64KB of configuration
information in EEPROM. This information is periodically sent to the host
server to be saved in a file. During a hot swap, the new Remote Access
Concentrator reads in this file at boot time and overwrites its EEPROM
with the configuration information from the Remote Access Concentrator
it is replacing. The new Remote Access Concentrator then functions as
the previous Remote Access Concentrator, except for the LAT key, which
needs to be reprogrammed.
If no EEPROM overwrite is desired when hot swapping, select
default values for that slot from the supervisory module on the
service port terminal.
