The procedure to disconnect other types of direct aach cables, other than direct aach breakout
cables, is the same as the procedure described in this topic.
Connect a Direct Aach Cable
CAUTION: To prevent ESD damage to the transceiver, do not touch the connector pins
at the end of the transceiver.
Ensure that you have an ESD grounding strap (not provided).
NOTE: Aer you connect a cable or aer you change the media-type conguraon, wait for
6 seconds for the interface to display operaonal commands.
NOTE: We recommend that you use only cables purchased from Juniper Networks with your
Juniper Networks device.
CAUTION: If you face a problem running a Juniper Networks device that uses a third-
party opc or cable, the Juniper Networks Technical Assistance Center (JTAC) can help
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 direct aach 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.
