Overview
NOTE:
A SIMM (memory module) is required for software version 1.20 and higher.
This procedure applies to an Access Navigator with two (redundant) Controller cards. In a
redundant system, the SIMM can be installed on the standby Controller without disrupting service.
Then, by using a CLI command to switch the active Controller to standby, a SIMM can be installed
on the other Controller.
To prevent service disruptions in an unprotected system with only one Controller card, another
Controller with compatible software can be installed temporarily (see Install Redundant Controller
Card on
page 6-49 ). The temporary Controller is switched to active mode before removing the
original Controller for SIMM installation using this procedure. After installation, the original
Controller is switched to active mode before removing the temporary Controller.
