Installing a disk shelf in a rack

Minimum hardware and software requirements

If the platform you are adding a disk shelf to is a FAS270 or FAS270c, the following requirements must be met for this procedure:

The minimum software release on your system is one of the following:
- Data ONTAP 7.0.4 or later
  Caution
  Do not attempt this procedure with any earlier software versions.
All three disk shelves must be DS14mk2 AT.

For all other platforms, the System Configuration Guide at http://now.netapp.com has more information on the minimum software requirements to support the disk shelf.

Installing a disk shelf

To install the disk shelf in a rack, complete the following steps.

WARNING
You must install each disk shelf with either the two-post telco tray kit or the four-post rail kit that came in your shipment package. If you choose to mid-mount the disk shelf, use the mid-mount brackets with the two-post telco tray kit. Do not ear-mount the disk shelf into a telco-type rack; the disk shelf will collapse from the rack under its own weight.

Step	Action
1	Verify that your storage appliance meets the minimum software requirements to support the disk shelf. See the System Configuration Guide at http://now.netapp.com for more information.
2	Verify that you received the envelope with the disk shelf ID labels.
3	Ground yourself to the system chassis using the grounding leash.
4	Use the rail kit installation flyer in the rail kit box to install the appropriate rail kits on the rack.
5	Install and secure the disk shelf onto the support brackets and rack.
6	Change the disk shelf ID with the following procedure: 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. Select the correct label from the envelope identified in Step 2 and attach it to the right flange of the new disk shelf.
7	If you are adding multiple disk shelves on the same loop, repeat Step 5 and Step 6 to install the remaining disk shelves.
8	If the platform you are connecting to is a...	Then...
	FAS270 or FAS270c	Remove the AT-FCX modules from the disk shelf that you are installing. Change the loop speed setting on the module to 1 Gb. See the following illustration. Caution The FAS270 and FAS270c function at a 1-Gb loop speed. An incorrectly set loop speed on the DS14mk2 AT results in an open loop condition.

	Platform other than a FAS270 or FAS270c	Go to Step 9.
9	Connect the grounding strap connecting the disk shelf to the other disk shelves or your storage appliance.
10	If the platform you are connecting to is a...	Then...
	FAS270 which by default has a single head module in the lower middle of the back of the disk shelf	Use the appropriate cable to connect AT-FCX B of the disk shelf to AT-FCX B of the other disk shelves or to your storage appliance. See Disk shelf cabling requirements for additional requirements. Note AT-FCX B is in the lower middle of the back of the disk shelf.
	A FAS270c or any other platform	Use the appropriate cable to connect both modules of the disk shelf to the other disk shelves or to your storage appliance. See Disk shelf cabling requirements for additional requirements.
11	Connect the two disk shelf power cords to each disk shelf that you are adding.
12	Turn on the power first to the disk shelves and then to the storage appliance.
13	Reboot the storage appliance.
