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

Fujitsu Downloads: Disk Qualification Package
• The best practice is to download and run Config Advisor after a new system installation.
Running Config Advisor after a new system installation allows you to verify SAS connections are cabled
correctly and that shelf IDs are unique within the HA pair or single-controller configuration.
If any SAS cabling or duplicate shelf ID errors are generated, follow the corrective actions provided.
You need network access to download Config Advisor.

SAS cable handling considerations
• Visually inspect the SAS port to verify the proper orientation of the connector before plugging it in.
The SAS cable connectors are keyed. When oriented correctly into a SAS port, the connector clicks into
place and if the disk shelf power is on at the time, the disk shelf SAS port LNK LED illuminates green. For
disk shelves, you insert a SAS cable connector with the pull tab oriented down (on the underside of the
connector).
For controllers, the orientation of SAS ports can vary depending on the platform model; therefore, the
correct orientation of the SAS cable connector varies.
• To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
Cables have a minimum bend radius. Cable manufacturer specifications define the minimum bend radius;
however, a general guideline for minimum bend radius is 10 times the cable diameter.
• Using Velcro wraps instead of tie-wraps to bundle and secure system cables allows for easier cable
adjustments.

Installing disk shelves with IOM12 modules for a new system installation

You install the disk shelves in a rack using the rack mount kits that came with the disk shelves.
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).
