CAUTION
Carefully follow the mechanical guides on each side of the power supply slot and make sure the
power supply is properly inserted in the guides. Never insert the power supply upside down.
7. After you insert the power supply, push gently on the power supply faceplate until the power
supply is fully seated.
8. Pull up on the handle on the power supply faceplate to lock the power supply in place.
9. For a 4-slot device, use the screwdriver to secure the two screws on either side of the power
supply faceplate.
10. Connect the AC power cord to the power supply faceplate.
11. Connect the power to the AC source.
LEDs on the power supply faceplate show the status of the power supply with the following colors:
•
For an AC supply, the AC OK and DC OK LEDs should be green, indicating the power supply is
providing power to the device components.
•
If the ALM LED is lit (amber), the power supply has failed.
For information about troubleshooting this problem, refer to
Table 27
on page 207.
Replacing fan assemblies
You can replace a fan or a fan control module while the router is powered on and running. The fans
and fan control modules are located on the rear panel of the router.
NOTE
Fan trays are hot swappable. However, a hot-swap procedure should be completed within five
minutes so the device will continue to function correctly without any fans. It is recommended that
you disconnect the power supply from AC power before installing or removing the fan tray.
Replacing fan assemblies in a 16-slot router
A 16-slot router has one fan assembly accessible from the front of the router and two assemblies
that are accessible from the rear. The front assembly pushes air into the router and the rear fans
pull air out.
You can remove and replace a fan assembly while a 16-slot router is powered on and running.
CAUTION
To avoid overheating of the 16-slot router, remove one fan assembly at a time, and replace it
promptly. Do not remove all fans from the device at once.
To replace a fan assembly, you need the following:
•
A new fan assembly, which you can order from Dell.
•
A small flat-blade screwdriver.
