Boot-Disk Sas Cable And The High-Speed Sas - IBM SAN Volume Controller Hardware Maintenance Manual

You can leave the fibre-channel and Ethernet cables connected, if you are using the
cable-management arm and if you are not removing the node from the rack.
6. Optional: Remove the node from the rack and place it on a flat, static-protective surface. See
"Removing the SAN Volume Controller from a rack" on page 40.
You can perform most service actions when the node is fully extended from the rack on its slide
rails. If the location of the node in the rack is too high or too low to work comfortably, you can
remove the node from the rack.
7. Remove the service controller. See "Removing the service controller" on page 75.
8. Pull the disk drives and filler panels out of the node slightly to disengage them from the back plate.
See "Removing the disk drive" on page 99.
9.
10. Remove fans 4, 5, and 6, as described in "Removing the SAN Volume Controller 2145-CF8 fans" on
page 209.
11. Disconnect all cables from the disk-drive backplane.
Note: You can also choose to disconnect the cables after removing the backplane from the brackets,
if that is easier for you.
The high-speed SAS cable and the boot-disk SAS cable are shown in Figure 117.
The boot-disk cable is shown after disconnecting the cable from the disk controller so that you can
see the connectors more clearly.
