Set the I.D. Selection and Configuration Switches
Each power supply in a redundant system must be assigned a different
identification number. To do this, you must set the I.D. selection switches
located on the left side of the module (figure 2). A cutout in the metal
cover of the module provides access to these switches.

l.D. Selection Switch
Switches 1 through 4 are for the power supply identification number.
Switches 5 and 6 are set based on the configuration zone.
To set the switches, follow this procedure:
1.
Close the I.D selection switch (1 through 4) that represents the
number you selected for that power supply.
2.
Determine the configuration zone being used so you can set switches
5 and 6. To determine the configuration zone, you must know the
maximum chassis current draw and the ambient air temperature of the
chassis. Refer to table B.
