Installing Disk Shelves With Iom12 Modules For A Hot-Add - Fujitsu ETERNUS AX Series Installation And Cabling Manual

Installing disk shelves with IOM12 modules for a hot-add

For each disk shelf you are hot-adding, you install the disk shelf into a rack, connect the power cords, power
on the disk shelf, and set the disk shelf ID before cabling the SAS connections.
Procedure
1. Install the rack mount kit (for two-post or four-post rack installations) that came with your disk shelf using
the installation flyer that came with the kit.
Attention: If you are installing multiple disk shelves, you should install them from the bottom to
the top of the rack for the best stability.
Do not flange-mount the disk shelf into a telco-type rack; the disk shelf's weight can cause it to
collapse in the rack under its own weight.
2. Install and secure the disk shelf onto the support brackets and rack using the installation flyer that came
with the kit.
To make a disk shelf lighter and easier to maneuver, remove the power supplies and I/O modules (IOMs).
For DS460C disk shelves, you can also use the four detachable handles that shipped with your disk shelf.
Handles (two on each side of the chassis) are installed by pushing up until they click into place. As you
slide the disk shelf onto the rails, detach handles using the thumb latch.
It is recommended that you use a mechanical hoist or lift if you are moving a fully loaded DS460C disk
shelf.
Attention: A fully loaded DS460C disk shelf can weigh approximately 247 lbs (112 kg).
3. If you are installing a DS460C disk shelf, install the components into the racked disk shelf; otherwise, go to
the next step.
If you purchased a partially populated disk shelf which does not have a drive in every drive slot, you must
ensure that:
• The first four slots (0, 3, 6, and 9) are occupied in each drawer.
This ensures proper airflow in the disk shelf.
• In a shelf with 30 drives, the remaining ten drives are distributed evenly throughout the shelf in slots 1
and 10 of each drawer.
The following illustration shows how the drives are numbered from 0 to 11 in each drive drawer within
the shelf. Slots 0, 3, 6, 9, and, in a shelf containing 30 drives, slots 1 and 10 in each drawer must contain
drives.
