Removing an SRX5400 Services Gateway MIC
The MICs are located in the MPCs installed in the front of the services gateway. A MIC
weighs less than 2 lb (0.9 kg).
To remove a MIC:
1.
Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the
MIC. If the MIC connects to fiber-optic cable, have ready a rubber safety cap for each
transceiver and cable.
2.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
3.
Power off the services gateway.
4.
Label the cables connected to the MIC so that you can later reconnect each cable to
the correct MIC.
5.
Disconnect the cables from the MIC. If the MIC uses fiber-optic cable, immediately
cover each transceiver and the end of each cable with a rubber safety cap.
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
you are inserting or removing cable. The safety cap keeps the port clean
and prevents accidental exposure to laser light.
6.
Arrange the cable 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.
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.
7.
On the MPC, pull the ejector knob that is adjacent to the MIC you are removing away
from the MPC faceplate. The ejector knob is located between the MIC and the
rotational knob that retains the MPC in the services gateway card cage. Pulling the
ejector knob unseats the MIC from the MPC and partially ejects it. See
