specifications for your 48 V power distribution system.
Turn the DC input power source on or reset the power source

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.
