Juniper Networks MX480 - Manual (Page 226)

CAUTION: Do not leave a fiber-optic transceiver uncovered except when
you are inserting or removing cable. The safety cap keeps the port clean
and prevents accidental exposure to laser light.
6. Insert the appropriate cables into the cable connectors on the PIC.
7. Arrange the cable in the cable management brackets to prevent it from dislodging or
developing stress points. Secure the cable so that it is not supporting its own weight
as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop.
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.
8. Use one of the following methods to bring the PIC online:
• Press the PIC offline/online button until the PIC LED lights green. For a PIC installed
in an FPC2 or FPC3, use a narrow-ended tool that fits inside the opening that leads
to the button.
• Issue the following CLI command:
user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot online
For more information about the command, see the Junos OS Operational Mode
Commands.
The normal functioning status LED confirms that the PIC is online. You can also verify
correct PIC functioning by issuing the
show chassis fpc pic-status command described
in “Maintaining MX480 PICs” on page 134 .
