Switch operations
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.
For more information about the power switch locations, see the
following figure.
2
Verify that the power output LED for 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.
