6.2.3

Replacing the Controller Module

 

If the controller module has failed, it must be replaced. To replace a failed controller module:

 

1.

Remove the failed controller module. (See Section 6.2.2 Removing the Controller Module)

 

 

If the DIMM module is undamaged it can be removed (See Section 6.3 DIMM Module

 

 

Replacement) and reused on the new controller module.

 

2.

Install a DIMM module on the new controller module. (See Section 6.3 DIMM Module

 

 

Replacement)

 

3.

Insert the controller module. Align the controller module with the controller module bay

 

 

at the rear of the subsystem. Gently slide the controller module in.

 

4.

Fasten the hand screws. Once fully inserted secure the controller module to the sub-

 

 

system by fastening the hand screws.

 

5.

Re-attach all the cables that were removed. These include the cables that connect to the

 

 

network or iSCSI initiators that were previously attached to the iSCSI ports, and any

 

 

cable that was attached to the RS-232C audio jack connector.

 

6.

Power up the system.

6.3DIMM Module Replacement

The subsystem comes with a pre-installed 1 GB (or above) DDR RAM DIMM module on the controller. If DDR RAM DIMM modules with a different size need to be used or the original memory module is damaged in some way, the pre-installed modules must be removed and the new ones installed. Replacement and installation instructions are described fully below.

The DIMM module is located on the controller board. The controller board is a sensitive com- ponent and must be treated with care to avoid being damaged.

CAUTION!

•

•

The pre-installed modules must be removed prior to installing new memory modules. Do this with care. Sensitive components can be damaged during the process.

The controller board in the controller module is a sensitive item. Please ensure that all anti-static precautions stipulated above are strictly adhered to. Only qualified techniciens should replace the DIMM module.

6.3.1DIMM Module Considerations

If the memory module on the subsystem controller module is going to be replaced, the follow- ing factors must be considered when purchasing replacement DIMM modules:

• Pre-installed DIMM module: The RAID comes with a 1 GB DDR RAM DIMM module pre- installed on the controller board. If you wish to change the size of the DIMM, then a new, separately purchased DIMM must be installed.

• Purchasing considerations: When purchasing a DDR RAM DIMM to install on the controller board, contact your vendor for an updated list of certified modules.

• DDR RAM DIMM modules supported: The RAID subsystem supports DDR RAM DIMM modules with memory capacities from 1 GB.

• Installation considerations: When installing the DIMM module, it is necessary to handle the controller module. The controller board is more susceptible to damage than the other components and must therefore be handled with extreme care. ALL anti-static precautions specified in Section 3.3 Safety Precautions must be strictly adhered to.

• Secure installation: When replacing the DIMM module, make sure that the new

DIMM module is firmly in place prior to installing the controller module. If the DIMM mod- ule is not firmly in place, the subsystem will not run and the controller will need to be removed and the DIMM module correctly installed.
