8.
Grasp the handles on the MIC faceplate, and slide the MIC out of the MPC card carrier.
Place it in the electrostatic bag or on the antistatic mat.

If you are not reinstalling a MIC into the emptied MIC slot within a short time, install
a blank MIC panel over the slot to maintain proper airflow in the MPC card cage.
Installing an SRX5400 Services Gateway MIC
To install a MIC:
1.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2.
If you have not already done so, power off the services gateway.
3.
If the MIC uses fiber-optic cable, verify that a rubber safety cap is over each transceiver
on the faceplate. Install a cap if necessary.
4.
On the MPC, pull the ejector knob that is adjacent to the MIC you are installing 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. See
Figure 83 on page 171 .

5.
Align the rear of the MIC with the guides located at the corners of the MIC slot.
6.
Slide the MIC into the MPC until it is firmly seated in the MPC. The ejector knob will
automatically move in towards the faceplate to lock the MIC in position as it seats.
If the MIC does not seat properly in the slot, pull the ejector knob all the way out and
try again to seat the MIC. The MIC will not seat properly unless the ejector knob is all
the way when you start to insert the MIC.
CAUTION: Slide the MIC straight into the slot to avoid damaging the
components on the MIC.
