•
ESD grounding strap
•
Phillips (+) number 2 screwdriver
To remove the upper or lower fan tray (see Figure 114 on page 270 and Figure 115 on page 271 ):
1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on
the chassis.
2. Reposition the cable manager before removing the lower front fan tray:
a. Unwrap any cables on the 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.
b. Simultaneously pull the two releases labeled PULL on the cable manager. Lift it up and outward to
lock it in place.
3. Using the Phillips (+) number 2 screwdriver loosen the captive screw on each side of the fan tray
faceplate.
4. Grasp both sides of the fan tray 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.
5. Pause for approximately 15 seconds to allow the fans to stop spinning.
6. When the fans stop spinning, press on the two latches located on the inside of the fan tray.
7. Place one hand under the fan tray to support it and pull the fan tray completely out of the chassis.
8. Proceed to “Installing an SRX5800 Services Gateway Fan Tray” on page 271 to install the replacement
fan tray.
