Replacing a RAID controller or expansion adapter

Use the following instructions to replace a RAID controller or expansion adapter. On

a chassis with two controllers, the controller or expansion adapter should be replaced

while the chassis is powered up (hot-swapped).

On a chassis with two controllers, if the controller microcode on the replacement

controller is not the same as that on the other currently installed controller, the

microcode on the replacement controller is automatically upgraded or downgraded to

match that on the currently installed controller.

Removing a RAID controller or expansion adapter

To remove a RAID controller or expansion adapter:

1. If you are removing a redundant controller or an expansion adapter, identify the

module to be replaced using NetCentral or verify that the module’s Fault LED is

on. If you are removing an operational RAID controller, use the Grass Valley

Storage Utility to disable the RAID controller. If there is no redundant controller,

power down the system.

2. Disconnect all the cables.

NOTE: The cable to the SAS connectors has a blue tab labeled “Press.” Be sure to

press forward on the blue tab, rather than down.

3. Remove the power cable and the controller cable connected to the module. Note

where the cables connect to the module. The SAS cables for the K2 10G Expansion

Chassis are keyed so that one end can only be used with the DP-IN connector and

the other end can only be used with the DP-OUT connector.

4. Take an ejector of the module in each hand. Open them to the left and the right.

(The ejectors are locked at the bottom.) The module comes out by freeing it on the

left and right. The diagram below shows the ejectors on a controller.

5. Holding the ejectors in both hands, pull horizontally approximately 4 inches.
