3.
Verify that your system halted.
If your storage system has an LCD display,
Halted
should appear on the display; otherwise,
you should check the storage system console to ensure the system is halted.
4.
Turn off the power switch on the disk shelf.
5.
Unplug all power cords from the disk shelf.
6.
Unplug and remove the cables connecting the disk shelf to the other disk shelves or the
storage system.
Note: Make note of the ports from which you unplugged the cables so that you can cable
the new disk shelf in the same way.
7.
Use a Phillips screwdriver to remove the screws securing the disk shelf to the rack.
8.
Remove the disk shelf from the rack.
To make the disk shelf lighter and easier to maneuver, remove the power supplies and I/O
Modules (IOMs). If you will be installing a disk shelf chassis, also remove the disk drives or
carriers; otherwise, avoid removing disk drives or carriers if possible because excessive
handling can lead to internal damage.
Attention: If you must remove disk carriers from
the DS4486 disk shelf, do not place hands on the
two disk drive boards exposed on the underside of
the disk carrier.
Note: You might want to use a mechanical hoist or lift if you decide to move a DS4243 or
DS4486 that is fully populated.
CAUTION: A fully populated DS4243 or DS4246
disk shelf can weigh approximately 110 lb (49.9
kg).
A fully populated DS2246 disk shelf can weigh
approximately 49 lb (22 kg).
A DS4486 disk shelf with the two IOMs, four
power supplies, and only four disk carriers can
weigh approximately 82 lbs (37 kg). A fully
populated disk shelf can weigh approximately 150
lbs (68 kg).
9.
Install and secure the replacement disk shelf onto the support brackets and rack.
10. If you installed a disk shelf chassis, insert all of the components that you removed in Step
on page 61; otherwise, go to the next step.
11. Reestablish the stack of disk shelves by connecting the cables to the replacement disk shelf's
ports exactly as they were connected to the disk shelf you removed.
