Installing the DC power supply

aid: Tightening the retaining screws on the DC power supply”
(page 37)

Tighten the retaining screws to firmly seat the power supply.

Attach the positive and negative terminal leads to the DC input
power source according to the proper safety and technical
specifications for your 48 V power distribution system.

Turn the DC input power source on or reset the power source
circuit breaker to provide power to the power supply.

Turn the power supply switch to the on position.

ATTENTION

Due to the N+1 power sharing architecture, if your chassis contains
two or three nonredundant power supplies, Nortel recommends that
you turn on the power supplies simultaneously. If you wait longer to
turn on the supplies, the power supplies shut off within 7 seconds. To
correct this condition, turn off the power supplies for 2 minutes, and
then simultaneously turn on the power supplies again.

If the LED on the power supply does not turn on, contact the
Nortel Technical Solutions Center.
