3. Use one of the following methods to take the port module offline:
•
Insert a pointed tool into the ONLINE pinhole on the front panel of the port module to press the
button behind it. Hold the button down until the OK/FAIL LED goes off.
•
Issue the following CLI command:
user@host>
request chassis fpc-slot
slot-number
pic-slot
slot-number
offline
For more information about the command, see Junos OS System Basics and Services Command Reference
at www.juniper.net/documentation/ .
4. Power off the services gateway.
5. Disconnect the cables from the port module. If the port module uses fiber-optic cable, immediately
cover each transceiver and the end of each cable with a rubber safety cap. Arrange the disconnected
cables in the cable management system to prevent the cables from developing stress points.
WARNING: Do not look directly into a fiber-optic transceiver or into the ends
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected
to a transceiver emit laser light that can damage your eyes.
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.
CAUTION: Avoid bending a 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.
6. Cover the ports on the port module with dust covers, if you remove the optical transceivers from the
IOC.
7. Using the Phillips (+) number 1 screwdriver loosen the captive screws that retain the port module in
its slot in the Flex IOC.
8. Grasp the captive screws and slide the port module straight out of the Flex IOC halfway.
