The air filters in the line card covers will prevent dust and other particles entering the chassis. If
an empty line card slot is not covered, dust and other particles may accumulate on the connector
pins of the installed line cards and SFBs and affect the performance of the router.
To remove a line card from an MX10004 router chassis:
1. Place the antistatic bag or antistatic mat on a flat, stable surface.
2. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other
end of the strap to one of the ESD points on the chassis. An ESD point is located above the status
LED panel on the front of the router chassis. See
3. Label the cables connected to each port on the line card so that you can reconnect the cables to the
correct ports.
4. Issue the following CLI command to take the line card offline:
request chassis fpc slot
slot-number offline
5. Unscrew the line card from the chassis by continually turning the handles to the left until the line
card is fully unseated. See
Figure 94: Remove an MX10004 Line Card
6. Using the handles, slide the line card halfway out of the chassis.
