Replacing an MX2020 Fan Tray
Removing an MX2020 Fan Tray
The fan trays are interchangeable and are hot-insertable and hot-removable.
To prevent overheating, install the replacement fan tray immediately after removing the existing fan tray.
To remove the upper or lower fan trays (see Figure 1 and Figure 2):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Reposition the DC cable manager, if necessary, before
removing the upper or lower fan tray:
Unwrap any cables on the DC cable manager, and remove the cables from the tray. Arrange the cables so that they do not block the front of the cable manager and tray, and secure them with temporary fasteners so that they are not supporting their own weight as they hang from the connector.
- Loosen the two captive screws on each side of the fan tray access panel and then open it.
- Loosen the two captive screws on the fan tray faceplate.
- While grasping the handle, press and hold the latch until
the status LED turns off. Pull the fan tray out approximately 1 to
3 inches until it stops.
Note The fan trays are interchangeable and are hot-insertable and hot-removable.
- Press and hold the latch a second time to disengage fan
operation. Place one hand under the fan tray for support while pulling
the fan tray completely out of the router.
Caution The double latch system is a safety mechanism. Damage to the fan tray will occur if you do not hold the latch while removing the fan tray.
- Place the fan tray on an antistatic mat or in an approved ESD bag.
Before removing a fan tray, make sure the fan blades have stopped completely.

tray for support, and align it into the slot.
Note When inserting the fan tray observe the correct orientation by the "this side up" label on the fan tray.
