Chapter 2 FC-AL Host Connections 2-13

2.3 Setting the Loop ID

This section explains how to set the loop ID of a controller that is connected to a

hub.

Tools and equipment needed:

■ Needlenose pliers

■ Jumpers (supplied with the StorEdge A3500/A3500FC unit)

■ Antistatic wrist strap

Every device attached to a SCSI or FC-AL bus must have a unique controller module

ID number in order to communicate. The factory default ID settings for controller A

and B are ID 5 and ID 4, respectively.

Note – Do not configure more than four controller modules on the same loop.

1. Locate the 16 pins on the rear of the FC-AL controller module (

FIGURE 2-8).

The eight pins on the right determine the host ID for controller 1(A); the pins on the

left determine the ID for controller 2(B).

2. Wearing the antistatic wrist strap, install jumpers on the pins as shown in

FIGURE 2-8.

If necessary, use the needlenose pliers to remove the jumpers.
