you diagnose the source of the problem. Your JTAC engineer might recommend that
you check the third-party opc or cable and potenally replace it with an equivalent
Juniper Networks opc or cable that is qualied for the device.
To connect a breakout cable:
1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end
of the strap to a site ESD point.
2. Remove the cable from its bag.
CAUTION: Do not leave the transceivers at the ends of the cable uncovered except
when connecng or disconnecng the cable. The rubber safety cap keeps the
transceivers clean and protected.
3. If the transceiver aached to the cable is covered with a rubber safety cap, remove the cap. Save the
cap.
4. If the port on the device is covered with a rubber safety cap, remove the cap. Save the cap. If you are
hot-swapping a cable, wait for at least 10 seconds aer removing the cable from the port before
installing a new cable.
CAUTION: Before you slide the transceiver into the port, ensure that the transceiver is
aligned correctly. Misalignment might cause the pins to bend, making the cable
unusable.
Do not bend the cables beyond their minimum bend radius. An arc smaller than a few
inches in diameter can damage the cables and cause problems that are dicult to
diagnose.
Do not let the cables hang free from the connector. Do not allow fastened loops of
cables to dangle, which stresses the cables at the fastening point.
5. By using both hands, carefully insert the transceiver in the empty port. The connectors must face the
chassis. Slide the transceiver in gently unl it is fully seated (see Figure 127 on page 225).
