Installing and Replacing Hardware
Step 3
Use a Phillips-head screwdriver to loosen the two screws on the fan tray.
Step 4
Grasp the fan tray by the handle and pull it from the chassis. If the fans are running, you will hear them
slow down as the tray disengages from its power connector.
Warning
The fans continue to turn at high speed for several seconds after the fan tray is removed from
the chassis. To avoid injury to your hands, touch the fan tray only by its handle until the fans
have stopped.
Note
If there is a second fan tray in the chassis, you will hear it speed up when you remove the first fan tray.
Step 5
Insert the replacement fan tray into the chassis. Make sure that the pins in the lower lip of the fan tray front
panel engage with the holes in the PEM below.
Step 6
Press the fan tray firmly into its slot to ensure that the power connectors mate. If the power is on, you
will hear the fans start to turn. The fault light for the fan tray you are installing will stay on until the
fans reach full speed, which takes several seconds. (Fan fault LEDs are Fan Tray 1 and Fan Tray 2 on
the PEM.)
Note
When you insert a fan tray, you might hear the fans in the other fan tray slow down; this is normal.
Step 7
Use the Phillips-head screwdriver to tighten the two fasteners on the fan tray.
Step 8
Use the Phillips-head screwdriver to replace the bezel.

Caution
Proper ESD protection is required whenever you handle Cisco digital subscriber line access multiplexer

ground straps to eliminate the risk of ESD damage to the equipment. Cards are subject to ESD damage
whenever they are removed from the chassis.
