To restart a high-capacity AC power supply after a shut down due to an
over-temperature situation:
1.
Move the power switch on the power supply to the off (o) position.
2.
Turn off power to where the AC line goes into the power distribution module (PDM)
area.
3.
Wait for the power supply LEDs to fade out and for the fans inside the power supply
to shutdown. This can take up to 10 seconds.
CAUTION: Do not attempt to power-on the power supply if the LED is
still lit and the fan is still running. If you do, the services gateway will not
reboot.
4.
Turn on power to where the AC line goes into the power distribution module (PDM)
area.
5.
Move the power switch on the power supply to the on (
|
) position.
6.
Verify that the LEDs on the power supply faceplate are properly lit.
7.
Issue the CLI
show chassis environment pem
command and verify the State is
ONLINE
and the Temperature is
OK
.
To restart a high-capacity DC power supply after a shut down due to an
over-temperature situation:
1.
Switch off the circuit breaker(s) on the DC distribution panel to remove power to
the chassis and power supplies.
2.
Switch on the circuit breaker(s) on the distribution panel to power up the chassis
and power supplies.
NOTE: The power switch on the power supplies is not part of the outer
or inner DC circuits and therefore does not need to be switched off when
restarting the chassis.
NOTE: If output power is not load-balancing correctly in the same zone on
a services gateway with a high-capacity AC or DC power supply module,
connect two feeds and change the DIP switch to
1 to boost the voltage on
the power supply module.
Each High Capacity AC or DC power supply accepts two AC or DC feeds in two unique
AC or DC receptacles. It is possible to operate with one feed, but there is a reduction in
