Kramer Sierra Viper 6464CVR-64 [19/88] Ac power connections

VIPER COMPOSITE SERIES

AC Power Connections

Viper Composite series routing switchers offer redundant power supplies but must be specified

prior to order. The power supplies are universal AC inputs. Voltage selection is not necessary

because the power supply senses the correct AC input automatically.

The rear of the frame has two AC connectors labeled Primary and Redundant regardless of if

redundant power supplies are installed. For non-redundant power systems only the AC connector

“primary” is connected.

There are 4 “health monitoring” LEDs on each power supply. The LEDs indicate fan and power

status.

If redundant power supplies are ordered, the frame will contain two complete power supplies with

health monitoring LEDs. If a power supply should fail the other power supply will automatically

take over.

If a non-redundant power supply system is ordered, the redundant power supply slot will contain

a power supply frame with only the fan and health monitoring LEDs. This is referred to as a “fan

sled”. The “Module power” LED will not be lit on the fan sled. The redundant power AC

connection need not be connected for units with non-redundant power supplies. The fan sled will

operate from the primary power supply.

The “Fault” LED (red) turns on if there is a fan failure.
