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 diameter can damage the cable
and cause problems that are difficult to diagnose.
Verify that the status LEDs on the PIC faceplate indicate that the SFP is functioning

correctly (there is an LED for each SFP port). For more information about the PIC
LEDs, see the T1600 Core Router PIC Guide. You can also verify PIC functioning by
issuing the show chassis fpc pic-status

Removing the T1600 XENPAK Module
To remove a XENPAK module (see Figure 144 on page 256):
Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the
1.
XENPAK module. Have ready a rubber safety cap for the XENPAK transceiver and the
cable.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
2.
the strap to one of the ESD points on the chassis.
Label the cable connected to the XENPAK module so that you can later reconnect it
3.
to the correct module.
Disconnect the cable from the XENPAK module. Immediately cover the transceiver
4.
and the end of the cable with a rubber safety cap.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
