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 (
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.
