Removing an SRX5400 Services Gateway MPC
An MPC installs horizontally in the front of the services gateway. A fully configured MPC can weigh up to
18.35 lb (8.3 kg). Be prepared to accept its full weight.
To remove an MPC:
1. Have ready a replacement MPC blank panel and an antistatic mat for the MPC. Also have ready rubber
safety caps for each MIC using an optical interface on the MPC that you are removing.
2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other
end of the strap to the ESD point on the chassis.
3. Label the cables connected to each MIC on the MPC so that you can later reconnect the cables to the
correct MICs.
4. Use one of the following methods to take the MPC offline:
•
Press and hold the corresponding online button on the craft interface. The green OK/FAIL 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
5. If you have not already done so, power off the services gateway.
6. Disconnect the cables from the MICs installed in the MPC.
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
inserting or removing a 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.
