To connect the router to external clocking devices, connect a cable with RJ-45 connectors
to each external clock input port:
Attach an electrostatic discharge (ESD) grounding trap on your bare wrist, and connect
1.
the strap to one of the ESD points on the chassis.
Plug one end of the RJ-45 cable into the external clock input ports on the front of the
2.
CB.
Plug the other end of the RJ-45 cable into the E1 or T1 external clocking device.
3.
Verify that the LEDs for the external clock inputs are lit steadily green.
4.
Repeat the cabling procedures as needed for the other CB.
5.
Configure the port. See the
6.
Junos OS Administration Library for Routing Devices.

Now connect PICs to the network by plugging in network cable. To connect cable to the
PICs (see Figure 63 on page
Have ready a length of the type of cable used by the PIC. For cable specifications, see

Supported Network Interface Standards by Transceiver for ACX, M, MX, and T Series
Routers, Network Cable and Transceiver Overview for ACX Series, M Series, and MX
Series Routers, and the M320 Multiservice Edge Router Interface Module Reference.
If the PIC cable connector port is covered by a rubber safety plug, remove the plug.

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.
