Removing A Controller Module Or Expansion Module - R/Evolution 2000 Series Troubleshooting Manual

Removing a Controller Module or Expansion
Module
As long as the other module in the enclosure you are removing remains online and
active, you can remove a module without powering down the enclosure; however
you must shut down a controller module as described in "Shutting Down a
Controller Module" on page 84.
Caution – Removing the module impacts the airflow and cooling ability of the
device. To avoid possible overheating, insert the replacement I/O module as quickly
as possible. If the internal temperature exceeds acceptable limits, the enclosure may
overheat and automatically shut down or restart.
Caution – When replacing a controller, ensure that less than 10 seconds elapse
between inserting the controller into a slot and fully latching it in place. Failing to
do so might cause the controller to fail. It it is not latched within 10 seconds,
remove the controller from the slot and repeat the process.
Note – Although the illustrations provided in the following steps show a controller
module, the instructions also apply to an expansion module.
To remove a controller module or expansion module:
1. Follow all static electricity precautions as described in "Static Electricity
Precautions" on page 80.
2. If removing the controller module, use RAIDar to check the status of the partner
module.
To ensure continuous availability of the system, be sure that the partner module is
online. If the partner is offline, resolve the problem with that module before
continuing this procedure.
3. If you are removing a controller module and the partner module is online, use
RAIDar to shut down the module that you want to remove; see "Shutting Down a
Controller Module" on page 84.
You need to use the Shut Down function for controller modules only. The blue OK
to Remove LED illuminates to indicate that the module can be removed safely.
4. Use RAIDar to illuminate the Unit Locator LED of the enclosure that contains the
module to remove.
