Connecting multiple disk shelves

To connect multiple disk shelves, complete the following steps.

Caution
Observe the Disk shelf cabling requirements and do not mix LRC/ESH/ESH2 modules within a shelf.

Step	Action
1	Connect the remaining disk shelves in ascending order by completing the following connections: Connect one end of the cable to the module A Output on the disk shelf. Connect the other end of the cable to the module A Input on the next disk shelf.
2	On all but the last disk shelf in the loop, place the terminate switch on LRC/ESH A to the Off position (up). Note ESH2 is self-terminating and does not have a terminate switch.
3	On the last disk shelf in the loop, place the terminate switch on LRC/ESH A to the On position (down). Note ESH2 is self-terminating and does not have a terminate switch.
4	Connect the remaining disk shelves in ascending order by completing the following connections: Connect one end of the cable to the module B Output on the disk shelf. Connect the other end of the cable to the module B Input on the next disk shelf.
	The following illustration shows the LRC of a DS14mk2 FC being connected to the LRC on another DS14mk2 FC.
5	On all but the last disk shelf in the loop, place the terminate switch on LRC/ESH B to the Off position (down). Note ESH2 is self-terminating and does not have a terminate switch.
6	On the last disk shelf in the loop, place the terminate switch on LRC/ESH B to the On position (up). Note ESH2 is self-terminating and does not have a terminate switch.
7	Connect the disk shelf to a power source. See Connecting the disk shelf to a power source.
