Figure 54. Removing a controller module from an enclosure
NOTE:
Removing a controller module shows a 4-port SAS controller module. However, all of the controller modules use
the same latching mechanism.
6. Swing the latch handle open, then grip the latch handle and ease the controller module forward from the slot.
7. Place both hands on the controller module body, and pull it straight out of the enclosure such that the controller module
remains level during removal.
Installing a replacement controller module in a dual-controller module enclosure
Perform the following steps to install a replacement controller module in a dual-controller module enclosure:
Before you begin any procedure, see ESD precautions on page 42.
1. Examine the replacement controller module for damage, and closely inspect the interface connector. Do not install the
replacement controller module if the pins are bent.
2. Grasp the controller module using both hands, and with the latch in the open position, orient the controller module and align
it for insertion into the target slot.
3. Ensuring that the controller module is level, slide it into the enclosure until it stops.
A controller module that is only partially seated will prevent optimal performance of the controller enclosure. Verify that the
controller module is fully seated before continuing.
4. Secure the controller module in position by manually closing the latch.
You should hear a click as the latch handle engages and secures the controller module to its connector on the back of the
midplane.
5. Reconnect the cables.
CAUTION:
If passive copper cables are connected to the controller module, the cable must not have a
connection to a common ground/earth point.
6. Update the firmware on the replacement controller module to the same version as the other controller module.
