Install Additional
Modules in the Shelf
To make AC/DC power connections, follow these steps:
1 Plug the power supply modules directly into the backplane of the shelf. Their low
voltage DC outputs are bussed across the backplane to the other modules. Make
sure that the power supply modules and the fan tray are in the shelf and that they
are fully seated in their backplane connectors. (See Figure 5.)
The PathBuilder S600 supports dual redundant power supplies, but only one
Power Supply Module is required for operation.

CAUTION: Before servicing the unit and handling AC/DC power leads, disconnect
all power supply cords. Always have a partner close by who is familiar with first aid
for electrical shock.
WARNING: DC Units are to be installed only in Restricted Access Areas (dedicated
equipment rooms, equipment closets, etc.) in accordance with Articles 110-16 or
110-17, and 110-18 of the National Electrical Code, ANSI/NFDA No.70.
2 Turn off the AC/DC power source and connect the AC/DC leads to the front of the
shelf. Dress the leads to the rack leaving a service loop.
3 Turn on the AC/DC power and verify that the POWER indicators on both Power
Supply Modules are on and that the fans are running.
The PathBuilder S600 ships with the factory-ordered modules installed. If you have
ordered additional modules, install them as described in this section; otherwise,
proceed to "Step 4: Connect I/O Cabling and Wiring" for instructions on how to
connect the factory-installed modules and verify front panel indicators.
