Removing an MX2020 Fan Tray
NOTE: The fan trays are interchangeable and are hot-insertable and hot-removable.
CAUTION: 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 210 on page 439 and Figure 211 on page 439):
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
2. 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.
3. Loosen the two captive screws on each side of the fan tray access panel and then open it.
4. Loosen the two captive screws on the fan tray faceplate.
5. 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.
6. 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.
7. Place the fan tray on an antistatic mat or in an approved ESD bag.
