3.1.1.2 Changing the Bus Node ID Plugs
Spare bus node ID plugs are supplied with your system. Use the spare
plugs when you add ISEs, reconfigure your system with an expander, or
create a dual-host configuration.
The bus node ID plugs have prongs on the back that indicate the bus node
number (and by default, the unit number) of the ISE. To remove a bus node
ID plug, grasp it firmly and pull straight out. To insert a bus node ID plug,
align the two center prongs with the two center slots and press the plug
into the slots. See Figure 3–2.

Use the rules below for renumbering your storage elements:
•
For each DSSI bus, do not duplicate bus node numbers for your storage
elements. You can have only one storage element identified as bus node
0, one storage element as 1, and so on.
•
By convention, the ISEs are numbered in increasing order from right
to left.
