To replace the SAN Volume Controller 2145-CG8 or 2145-CF8 disk-drive backplane, complete the
following steps:
1.
Align the tabs on the disk-drive backplane with the slots on the backplane bracket.
2. Insert the 2145-CF8 disk-drive backplane tabs into slots on the backplane bracket and push the
disk-drive backplane down until the backplane is fully seated and the tabs locked in place.
You can reconnect the boot-disk cable to the connector on the left side (when viewed from the rear)
of the back of the backplane before installing the backplane into the brackets, or you can connect the
cable after you install the backplane, if that is easier for you.
The other end of this cable attaches to the disk-controller and USB riser card assembly, as shown in
Figure 123 on page 136.
If you are using solid-state drives (SSDs), you can connect the labelled end of the high-speed SAS
cable to the connector in the middle of the back of the disk-drive backplane. The other end of this
cable attaches to the high-speed SAS adapter at the rear of the node.
