own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled
loop in the cable management system. Placing fasteners on the loop helps to maintain
its shape.
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.
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend
radius.An arc smaller than a few inches in diametercan damage the cable
and cause problems that are difficult to diagnose.
7. Verify that the status LEDs on the PIC faceplate indicate that the CFP is functioning
correctly. For more information about the PIC LEDs, see the PTX5000 Packet Transport
Switch PIC Guide. You can also verify PIC functioning by issuing the show chassis fpc
pic-status command.

The upper horizontal fan tray is located below the craft interface, and the lower horizontal
fan tray is located above the horizontal air filter. Each horizontal fan tray weighs about
16.3 lb (7.4 kg).
CAUTION: Do not remove both horizontal fan trays at the same time.
Removing both front fan trays might cause the packet transport switch to
shut down.
To remove a horizontal fan tray (see Figure 65 on page 190 and Figure 66 on page 190):
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 screw on the left side of the fan tray faceplate, using a Phillips (+)
screwdriver, number 2.
