your facility relative to the SG1 power version you selected.
SG-1 Chassis
The SG-1 chassis provides four 100 to 240 Vac (50 to 60 Hz) power supplies with AC power connectors. You must
install one power supply for every five Service Creation Cards installed in a chassis (three power supplies are
required for a chassis having slots 1 through 16 fully populated). If you want redundant power, install an additional
power supply in an open power module slot. It is recommended to have one power module above the minimum to
provide uninterrupted service should a power module fail.

Facility Requirements for AC Power
Verify that the facility AC power source for the primary connection falls within the recommended voltage range of 110
to 220 Vac with a maximum current of 10 amps for 110 Vac and 5 amps for 220 Vac.

When slots in an SG-1 chassis do not contain a card, the slot must be covered with a blank faceplate to prevent
personnel contact with back panel connectors and to maintain proper air flow within the chassis.

in functional groups in adjacent slots for ease of
identification.

Redundancy
Add an additional SCC, of the same type, in slots
1 through 16 to have an additional card that
