Connecting a disk shelf to a storage appliance

Assumptions about this procedure

The assumption about this procedure is that the disk shelf is the only disk shelf connected to the storage appliance or it is the first disk shelf in a single loop.

Connecting a disk shelf to a storage appliance

To connect the disk shelf to a storage appliance, complete the following steps.

Step	Action
1	Put on the antistatic wrist strap and grounding leash.
2	Make sure that the storage appliance and the disk shelf are turned off.
3	If...	Then...
	Your storage appliance has an FC-AL adapter with a single copper interface	Connect the cable to the FC-AL adapter on the storage appliance.
	Your single filer has two FC-AL adapters with single copper interfaces	Connect the cable to one of the FC-AL adapters on the filer.
	Your storage appliance has a dual optical interface	Connect one end of the dual-headed cable into Port A (Port 1) of the adapter on the storage appliance.
4	If the LRC/ESH A input...	Then...
	Has a copper interface	Connect the other end of the cable to the LRC A Input on disk shelf 1. If applicable, tighten the locking screws on the connector with a screwdriver.
	The following illustration shows a DS14 connected to a storage appliance using a copper interface.
	Has an optical interface	Connect the other end of the dual-headed cable to the LRC/ESH A Input on disk shelf 1.
	The following illustration shows a DS14 connected to a storage appliance using a dual optical interface.
5	Set the termination switch on Channel A to the On position (down). The following illustration shows the termination switch set to the On position on LRC/ESH A.
6	If...	Then...
	Your storage appliance has an FC-AL adapter with a single copper interface	Go to Step 7.
	Your single filer has two FC-AL adapters with single copper interfaces	Connect the cable to the second FC-AL adapter on the filer.
	Your storage appliance has a dual optical interface	Connect one end of the dual-headed cable into Port B (Port 2) of the adapter on the storage appliance.
7	If the LRC/ESH B input...	Then...
	Is a copper interface on a DS14 and is not part of a clustered filer system	Place a terminator on the Fibre Channel input of LRC B.
	Has a copper interface and your single filer and has two FC-AL adapters with single copper interfaces	Connect the other end of the cable to the LRC B Input on disk shelf 1. If applicable, tighten the locking screws on the connector with a screwdriver.
	Is part of a clustered filer, mirrored cluster, or MetroCluster system	See the cluster guide for your filer for more information.
	Has an optical interface	Connect the other end of the dual-headed cable to the LRC/ESH B Input on disk shelf 1.
8	If the disk shelf...	Then...
	Is the only disk shelf in the loop connected to the storage appliance	Set the termination switch on Channel B to the On position (up). Note The On position of LRC/ESH B is the inverse of LRC/ESH A. Connect the disk shelf to a power source. See Connecting the disk shelf to a power source.
	Is the first disk shelf in a loop of disk shelves	Connect the disk shelf to the remaining disk shelves. See Connecting multiple disk shelves.
