Removing the T1600 Standard Lower Front Fan Tray

The lower front fan tray is located below the front air filter. Each front fan tray weighs
about 18.6 lb (8.4 kg).
Attach an electrostatic discharge (ESD) grounding strap to your wrist, and connect
1.
the strap to one of the ESD points on the chassis.
Unwrap any PIC cables from the spools on the front cable management system and
2.
remove the cables from the tray. Arrange the cables so that they do not block the
front cable management system and tray, and secure them with temporary fasteners
so that they are not supporting their own weight as they hang from the connector.
CAUTION: Do not let fiber-optic cable hang free from the connector. Do
not allow fastened loops of cable to dangle, which stresses the cable at
the fastening point.
Simultaneously pull the two releases on the front cable management system. Lift it
3.
up and outward to lock it in place to access the lower fan tray.
Rearrange the PIC cables in the front cable management system. For more information
4.
about proper cable arrangement, see "Maintaining T1600 PICs and PIC Cables" on
page 166.
Loosen the captive screws on the corners of the fan tray faceplate.
5.
Grasp the handles and pull the fan tray halfway out of the chassis.
6.
WARNING: To avoid injury, keep tools and your fingers away from the fans
as you slide the fan tray out of the chassis. The fans might still be spinning.
When the fans stop spinning, place one hand under the fan tray to support it and pull
7.
the fan tray completely out of the chassis.
