To remove an IOC (see Figure 54 on page 118):
Have ready a replacement IOC or blank panel and an antistatic mat for the IOC.
1.
Also have ready rubber safety caps for each IOC you are removing that uses an
optical interface.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
2.
connect the strap to one of the ESD points on the chassis. For more information
about ESD, see "Preventing Electrostatic Discharge Damage" on page 152.
Label the cables connected to each port on the IOC so that you can later reconnect
3.
the cables to the correct ports.
Use one of the following methods to take the IOC offline:
4.
Press and hold the corresponding online button on the craft interface. The
green OK LED next to the button begins to blink. Hold the button down until
the LED goes off.
Issue the following CLI command:
user@host>request chassis fpc slot slot-number offline
For more information about the command, see the JUNOS System Basics and
Services Command Reference.
Disconnect the cables from the IOC. If the IOC uses fiber-optic cable, immediately
5.
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 cable connected to a
transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting
or removing cable. The safety cap keeps the port clean and prevents accidental
exposure to laser light.
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.
Simultaneously turn both of the ejector handles counterclockwise to unseat the
6.
IOC.
Grasp the handles and slide the IOC straight out of the card cage halfway.
