Replacing the disk-drive backplane
You might have to replace the disk-drive backplane, which includes the simple-swap SAS backplane in
the SAN Volume Controller 2145-CF8 or the hot-swap SATA backplane for a SAN Volume Controller
2145-8A4 or SAN Volume Controller 2145-8G4.
Replacing the SAN Volume Controller 2145-CF8 disk-drive backplane
You can replace the SAN Volume Controller 2145-CF8 disk-drive backplane, which includes the SAS back
plate.
DANGER
Multiple power cords. The product might be equipped with multiple power cords. To remove all
hazardous voltages, disconnect all power cords.
To replace the SAN Volume Controller 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 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 disk-drive backplane before installing the backplane onto 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 125 on page 122.
