Replacing the T1600 Front Air Filter
Removing the T1600 Front Air Filter
The front air filter, located below the FPC card cage in the front of the chassis, and installs horizontally. The front air filter weighs approximately 1 lb (0.5 kg).The air filters are hot-insertable and hot-removable.
To remove the front air filter (see Figure 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.
- Unwrap any PIC cables from the spools on the cable
management system, and remove the cables from the tray. Arrange the
cables so that they do not block the front of the 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 cable management system. Lift it up and outward to lock it in place to access the air filter.
- Loosen the captive screws on the corners of the air filter faceplate.
- Grasp the handles and pull the air filter straight out of the chassis.
- Remove the filter element from the air filter frame (see Figure 2).
