To replace a CFM card:
1.
Place an electrostatic bag or antistatic mat on a flat, stable surface.
2.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis. For more information about ESD, see
“Preventing
Electrostatic Discharge Damage to the SRX3400 Services Gateway” on page 145 .
3.
If you are replacing a cold-swap-only CFM, power off the services gateway. See
“Field-Replaceable Units on the SRX3400 Services Gateway” on page 109 for a list of
hot-swappable and cold-swap-only components.
To power off the services gateway, press the Power button on the front panel of the
Switch Fabric Board (SFB) for three to five seconds.
The
PWR
LED blinks to show you that the services gateway is shutting down. Wait for
the services gateway to shut down before you proceed to the next step.
4.
If you are replacing a hot-swappable CFM such as an NP-IOC without powering off
the services gateway, toggle the CFM offline and power it off by pressing its
ONLINE
button for five or more seconds.
NOTE: You may find it easiest to use a pen, screwdriver, or other tool to
press the button.
5.
For IOCs or NP-IOCs, disconnect any cables connected to the Ethernet ports, marking
them so they can be reconnected in the proper location. If the IOC or NP-IOC 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 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.
6.
Loosen the captive screws at each end of the CFM faceplate.
7.
Grasp the CFM by its handle and slide it halfway out of the chassis.
