The 3500/15 AC and DC Power Supplies are half-height
modules and must be installed in designated slots on the left
side of the rack. The 3500 rack can contain one or two power
supplies with any combinations of AC and DC. Either supply
can power a full rack.
When two power supplies are installed in a rack, the one in
the lower slot acts as the primary supply, and the other in the
upper slot acts as the backup supply. If installed, the second
supply is the backup for the primary one.
Removing or inserting either power supply module does not
disrupt operation of the rack as long as a second power
supply is installed.
The 3500/15 AC and DC Power Supplies accepts a wide range
of input voltages and converts them to voltages acceptable
for use by other 3500 modules. The following power supplies
are available with the 3500 Series Machinery Protection
