2.5.1 Inserting Bus Node ID Plugs
Spare bus node ID plugs are shipped with each system and expander. The
part number for these plugs is 12–28766–19. The SCSI plugs for RZ-series
ISEs are a light gray. The part number for these plugs is 12–28766–28.
Bus node ID plugs have prongs on the back that identify the bus node
number (and by default, the unit number) of the ISEs to the system.
To insert a bus node ID plug, align the two center prongs with the two
center slots on the ISE front panel as shown in Figure 2–14. To remove a
bus node ID plug, grasp it firmly and pull it straight out.
Use the following rules for numbering bus node IDs for RF-series ISEs:
• For each DSSI bus, do not duplicate bus node numbers for storage
elements. You can have only one storage element on bus 0 identified
