Removing an MX5, MX10, MX40, and MX80 Fan Tray
NOTE: To prevent overheating, install the replacement fan tray immediately
after removing the existing fan tray.
To remove the fan tray (see Figure 41 on page 103):
1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2. Loosen the captive screw on the fan tray faceplate.
3. Grasp the fan tray handle, and pull it out approximately 1 to 3 inches.
WARNING: To avoid injury, keep tools and your fingers away from the fans
as you slide the fan module out of the chassis. The fans might still be
spinning.
4. Press the latch located on the inside of the fan tray to release it from the chassis.
5. Place one hand under the fan tray to support it, and pull the fan tray completely out
of the chassis.
