There are two methods of writingthe EEPROMinformation to the host
file:
Whenevera change is made to EEPROM, a 5 minute timer is
started.When the timer expires, the contents of the
EEPROM memory are copied to an internal buffer in the
Remote AccessC oncentratorRAM and encrypted. The file
is then transferredto the host specified in the configuration
parameter pref_dump_addr.The filename used to store the
EEPROMinformation on the host is params.n.n.n.n(where
n.n.n.nistheIPaddressoftheRemoteAccess
Concentrator).
In addition,writing the EEPROM information to the host
can be forced (bypassingthe 5 minute timer) by using the
Remote Access Concentrator’s superuser cp -e c ommand.
This can be doneat any time and typically is done if you
havejust completed making changes to one of the
configurationfiles or some of the configuration parameters.
It will be necessaryto configurethe replacement Remote Access
Concentratorto define the LATkey, because it isn’t restored during a hot
swap.
Forthe hot swap to be successful, the module being replaced and the new
module must both be registeredfor the same software options.
