INSTALLATION AND OPERATION OF MODEL 6010A

1. Plug the Universal Switching Power Supply into the Model 6000A card cage. The unit

will occupy three, adjacent positions. (You may choose which three.) If redundant

operation is desired, additional Model 6010A units may also be inserted, with each

occupying an addition three positions.

2. Plug a suitable line cord into the rear IEC power connector. Note that the Model 6010A

will automatically operate from all AC power sources between 90 and 260 volts at 50 or

60 Hz. No user adjustments are required.

3. Use the front panel power switch to turn the unit on. An illuminated power indicator

LED signifies the presence of power.

The Model 6010A universal switching power supply is "hot swappable," meaning

that it may be inserted or removed from the card cage without first turning off the power.

This feature is important when using redundant power supplies, as it gives the user

freedom to remove or add a second power supply while maintaining operation of all

transmission modules in the cage.

Do not use the Model 6010A universal switching power supply and an external

user-provided power source simultaneously. Doing so may result in damage to either

the supply or to the transmission card/modules in the card cage.

BUILT-IN ALARM FEATURE FOR REDUNDANT OPERATION

The Model 6010A contains an output voltage-sensing circuit that operates when two

or more power supplies and a model 6020A Alarm Sensing Module are employed in the

same card cage. If one supply should fail, a signal is produced that will activate the Alarm

Sensing Module. This results in a blinking LED, a piezo sounder and activation of a set of

external contacts (on the Alarm Sensing Module) that can be used to remotely signify the

occurrence of the failure.

This feature is not available when only one power supply is employed.
