Installing a disk shelf in a rack

Put on the antistatic wrist strap and grounding leash.

If the disk shelf is...

Then...

Part of a new storage appliance system that you are installing

Install your storage appliance. See your storage appliance hardware guide for more information.

An addition to an existing storage appliance system

Verify that you received the envelope with the disk shelf ID labels.

Select two holes on each side of the rack for the installation.

If you are using the...

Then...

Two-post telco tray kit

1. Align the left-post screw holes on the two-post rack with the screw holes on the left half of the telco tray, then secure it to the post with two M5 screws.
2. Align the right half of the telco tray with the left half and repeat Step 1 to secure it to the post.

The following illustration shows the two-post telco tray kit being installed.

To flush-mount the disk shelf

1. Install the disk shelf onto the two-post telco tray and retain it with the mounting screws to secure the disk shelf mounting flanges to the telco-type rack.
2. Conceal the mounting screws with the provided bezel mounting screw covers.

The following illustration shows a DS14 being flush-mounted onto the two-post telco tray.

To mid-mount the disk shelf

1. Select two holes in the middle of each side of the disk shelf to which you want to attach the center-of-gravity brackets and secure the bracket with the #10 Phillips head screws.

The following illustration shows a DS14 installed in a rack using a center-of-gravity bracket.

1. Align each bracket on the side of the disk shelf with the chosen holes on the rack and secure the bracket with the #10 Phillips head screws.

Four-post rail kit

For Step 1 through Step 5, see the accompanying illustration.

1. Connect the left support with the left rail, using three M5 nuts, three lock washers, and three M5 x 10 screws. Leave them loose enough so that you can adjust the length of the rail.
2. Align the holes in the front of the assembled rail with the front post of the four-post rack, and secure it to the post with two location pins and washers.
3. Attach the rear of the assembled rail to the rear post using two M5 x 10 screws, washers, and lock washers, then tighten the rail and support.
4. Repeat Step 1 through Step 3 for the right support rail.
5. Install the clip nuts for the disk shelf into the equipment rack posts. The bottom-most clip nut should be directly above the bottom locator pin and the top clip nut should be six holes above the bottom clip nut.
6. Install the disk shelf onto the rack mount kit and retain it with the mounting screws to secure the disk shelf mounting flanges to the front posts of the rack.
7. Conceal the mounting screws with the provided bezel mounting screw covers.

The following illustration shows how to install a four-post rail kit.

If the installed disk shelf is...

Then...

Part of a new storage appliance system

Make sure that the disk shelf ID is correct.

Note
For a single disk shelf installation, the disk shelf ID is 1.

An addition to an existing storage appliance system

Change the disk shelf ID with the following procedure:

1. Press the thumbwheel switch on the rear of the disk shelf and use the + button to raise the number and the - button to lower the number to a valid ID from 1 through 7.

   Note
   If you change a disk shelf ID, you must power-cycle the disk shelf for the new ID to take effect. The disk shelf ID display on the front of the disk shelf blinks until you power-cycle the disk shelf.

2. Select the correct label from the envelope identified in Step 2 and attach it to the right flange of the new disk shelf.

If disk shelves in the loop to which you are adding the new disk shelf have...

Then...

LRCs

• DS14 only: Go to Step 7.
• A mix of DS14 and DS14mk2 FC: Set the loop speed to 1 Gb.

  Caution
  An incorrectly set loop speed results in an open loop condition.

ESHs

• DS14 only or a mix of DS14 and DS14mk2 FC: Set the loop speed to 1 Gb.
• DS14mk2 FC only that are running at 1 Gb: Set the loop speed to 1 Gb.
• DS14mk2 FC only that are running at 2 Gb: Set the loop speed to 2 Gb.

  Caution
  An incorrectly set loop speed causes the storage appliance to panic.

If there are multiple disk shelves in the installation on the same loop, follow Step 4 and Step 5 to install the remaining disk shelves in ascending numerical order, according to the IDs on their labels.
