Resetting the switch

The number of supported Power over Ethernet (PoE) modules depends on
the power supply rating (110 volts [V]AC nominal or 220 VAC nominal),
the power supply model, and the number of power supplies. For more
information, see Ethernet Routing Switch 8300 Planning — Power
Considerations, (NN46200-511).
Prerequisites
•
Ensure that the power supply is seated properly.
•
Verify that the AC power cords are connected to the power supplies
and connected to AC power outlets.
Procedure steps
Step
Action
1
On each AC power supply, turn the power switch to the on
position.
ATTENTION
When you first install a chassis that contains two or three
power supplies, you must turn on two of the power supply units
simultaneously. If you wait longer to turn on the second power
supply, one of the power supplies could shut down. To correct this
condition, turn off both power supplies, wait at least 30 seconds, and
then turn on both power supplies again simultaneously.
2
Verify that the power LED on each power supply lights green.
3
Verify that the power supply status LEDs and the fan LED on the
8393SF/CPU or 8394SF/CPU module light green.
After you turn on the switch, each module automatically
initiates a diagnostic test to verify proper module function. See
“Successful installation verification” (page 32)
.
4
Verify that air is flowing from the cooling fans out through the
vents of the chassis.
5
If the power supply LED remains off, or if you cannot feel air flow
from the chassis vents, turn the DC power supplies off, and then
turn them on again.
6
If the problem persists, contact the Nortel Technical Solutions
Center.
