Changing the DSSI Node ID Plugs (BA400-Series OCPs)
Spare Plugs
Spare DSSI node ID plugs are supplied with the EF5XX. Use
these spare plugs to reconfigure your DSSI system because of
adding or removing ISEs or creating a multihost configuration.
Removal The DSSI 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 DSSI node ID plug, grasp it firmly and pull it
straight out.
Insertion To insert a new plug, align the two center prongs with the two
center slots and press the plug into the slots.
Renumbering
ISEs Use the following rules to renumber your ISEs:
For each DSSI bus, do not use duplicate DSSI node IDs.
By convention, ISEs are numbered in increasing order from
right to left and top to bottom.
Use a blank DSSI node ID plug where no ISE is present.
NOTE
If you change the bus node ID plugs while the
system is operating, you must turn off the system
and then turn it back on for the new plug positions
to take effect.
