Setting the Loop ID

Setting the loop ID of the Sun StorEdge A3500 FC array is different from the
procedure for the Sun StorEdge A5200 array and for the Sun StorEdge T3 array.

To Set the Loop ID of a Sun StorEdge A3500 FC
Controller

This section explains how to set the loop ID of a Sun StorEdge A3500 FC controller
that is connected to a switch.

Tools and equipment needed:

Needle-nose pliers

Jumpers (supplied with the Sun 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.

Caution –

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

1. Attach the antistatic wrist strap to your wrist and to the metal casing of the switch.

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

FIGURE 2-15

).

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).

3. Install the jumpers on the pins as shown in

FIGURE 2-15

.

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