Replacing Controller Module Components

The controller module consists of the components shown below:

•DIMM Module

The DIMM module can be replaced when the DIMM module fails or if a larger capacity DIMM module is required.

•Controller Module

If the controller module in a single controller model fails, it is necessary to power the sys- tem down and replace the controller.

6.2.1

Controller Module Maintenance Overview

•

•

•

The controller module contains a DIMM module. When replacing the controller module, these components can be removed and used on the new controller module if they are undamaged.

When replacing the controller module, you must remember that the controller board

is one of the most sensitive components in the RAID subsystem. All previously stipulated safety precautions (see Section 3 Hardware Installation) must be strictly adhered to. Fail- ure to adhere to these precautions can result in permanent damage to the controller board.

For your own safety and that of the subsystem, make sure that no power is being supplied to the system prior to replacing the controller module.

6.2.2

Removing the Controller Module

 

To remove the controller module:

 

1.

Turn off the subsystem. If possible power off the subsystem in the way described in

 

 

Section 5 Subsystem Connection and Operation. If it is not possible to do this turn off both

 

 

PSU modules and disconnect the power cords.

 

2.

Disconnect all cables that are connected to the controller module you wish to replace.

 

 

These include the Ethernet cables connected to the network, and any cable connected to

 

 

the RS-232C audio jack connector.

 

3.

Loosen the retention hand screws. Hand screws are located on both sides of the RAID

 

 

controller faceplate. Press these screws and loosen them so that the controller can be

 

 

removed from chassis.
