Controller 2145-CG8 or 2145-CF8
The SAN Volume Controller 2145-CG8 has two backplanes. Each backplane supports four of the
eight drive bays. One backplane supports the boot disk in drive bay 6 and drive bays 4, 5, and 7,
which are either reserved or empty. The other backplane supports the optional solid-state drives
(SSDs) in drive bays 0, 1, 2, and 3.
1 Boot-disk signal cable that is plugged into the disk-drive backplane to support drive bay 6 on
the SAN Volume Controller 2145-CG8 or drive bay 4 on the SAN Volume Controller 2145-CF8
2 High-speed SAS-adapter cable that is plugged into the middle of the disk drive backplane to
support drive bays 0, 1, 2, and 3
(Not pictured) Backplane-control cable that is in the lower right connector on the back of the
backplane
12. Lift up the disk-drive backplane ( 1 in each of the following two illustrations to disengage the
backplane edges (2145-CG8) or tabs (2145-CF8) ( 2 ) from the slots ( 3 ) on a backplane bracket.
In the 2145-CG8 node, pull up slowly on each backplane until it is clear of the slots on the bracket
and remove it from the node, as shown in Figure 114 on page 129.
