Replacing the T1600 Lower Front Fan Tray (FANTRAY-T4000)

 

The lower front fan tray is located below the front air filter. Each front fan tray weighs about 20.4 lb (9.3 kg). The fan trays are hot-insertable and hot-removable. The upper and lower fan trays are interchangeable with each other.

Removing the T1600 Lower Front Fan Tray (FANTRAY-T4000)

To remove a lower front fan tray (see Figure 1):

  1. Attach an electrostatic discharge (ESD) grounding strap to your wrist, and connect the strap to one of the ESD points on the chassis.
  2. Unwrap any PIC cables from the spools on the front cable management system, and 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.

  3. Simultaneously pull the two releases on the front cable management system. Lift it up and outward to lock it in place to access the lower fan tray.
  4. Rearrange the PIC cables in the front cable management system. For more information about proper cable arrangement, see Maintaining T1600 PICs and PIC Cables.
  5. Loosen the captive screws on the corners of the fan tray faceplate.
  6. Grasp the handles and pull the fan tray halfway out of the chassis.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.

  7. When the fans stop spinning, place one hand under the fan tray to support it and pull the fan tray completely out of the chassis.
