disk shelf
Install the two-post telco tray kit or four-post rail kit to support the disk shelf.
Attention: For two-post mid-mount installations, you must use
the mid-mount brackets in addition to the two-post telco tray
kit.
DS4486 disk shelf Install the four-post rail kit to support the disk shelf.
Note: If you are installing a DS4486 disk shelf and you are installing it in a
NetApp cabinet, you should have received the X8783 rail kit. If you are
installing the disk shelf in a third-party cabinet, you should have received the
X5529 or X5526 rail kit.
3.
Install and secure the disk shelf onto the support brackets and rack.
To make the disk shelf lighter and easier to maneuver, remove the power supplies and I/O
modules (IOMs). Avoid removing the disk drives or carriers if possible, because excessive
handling can lead to internal damage.
It is recommended that you use a mechanical hoist or lift if you are moving a fully loaded
DS4243 or DS4486 disk shelf.
Attention: A fully populated DS4243 or DS4246
disk shelf can weigh approximately 110 lbs (49.9 kg).
A fully populated DS2246 disk shelf can weigh
approximately 49 lbs (22 kg).
A DS4486 disk shelf with the two IOMs, four power
supplies, and four disk carriers can weigh
approximately 82 lbs (37 kg). A fully populated disk
shelf can weigh approximately150 lbs (68 kg).
4. Reinstall any power supplies and IOMs you removed to install your disk shelf into the rack.
If you installed a DS4486 disk shelf, carefully unpack and insert the remaining disk carriers.
Note: Do not place hands on the two disk drive boards exposed on the underside of the disk
carrier.
5. If you are adding multiple disk shelves, repeat Steps 3 through 4 for each disk shelf you are
installing.
6. Connect the power supplies for each disk shelf:
a. Connect the power cords first to the disk shelves, securing them in place with the power
cord retainer, and then connect the power cords to different power sources for resiliency.
Note: If you have a disk shelf with four power supplies, connect power supplies in slots
1 and 3 to one power source and power supplies in slots 2 and 4 to a different power
source.
b. Turn on the power supplies for each disk shelf and wait for the disk drives to spin up.
When the disk shelf has the maximum number of supported power supplies, all disk drives
or carriers spin up at the same time. However, if one or two power supplies have faulted in
a disk shelf with four power supplies, or if one power supply has faulted in a disk shelf with
two power supplies, disk drives spin up in sets of six at 12-second intervals.
7. Change the shelf ID for each disk shelf you hot-added by completing the following substeps:
