Removing a PTX5000 Vertical Fan Tray
The vertical fan tray is located in the front of the chassis. The vertical fan tray contains
fourteen fans and weighs about 26.8 lb (12.2 kg).

Transport Switch with the fan trays removed for more than one minute.
To remove the vertical fan tray (see Figure 69 on page 193):
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. Loosen the captive screws at the right of the fan tray faceplate, using a Phillips (+)
screwdriver, number 2.
NOTE: The two captive screws on the left are for the vertical air filter.
3. Grasp the handle and pull the fan tray until it stops (approximately 1.5 inches).
4. Place one hand under the fan tray to support it and pull the fan tray completely out
of the chassis.
WARNING: To avoid injury, keep tools and your fingers away from the fans
asyou slide the fan tray out of the chassis. The fansmight still be spinning.
