Resetting the switch 45
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,
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
1On 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.
2Verify that the power LED on each power supply lights green.
3Verify 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).
4Verify that air is flowing from the cooling fans out through the vents of the chassis.
5If 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.
6If the problem persists, contact the Nortel Technical Solutions Center.
Resetting the switch
Reset the switch to reboot the switch hardware without cycling power.
