CAUTION: Before performing a swap test, always check for bent pins in the
midplane and check the SFM for stuck pins in the connector. Pins stuck in
the component connector can damage other good slots during a swap test.
To perform a swap test on an SFM:
Remove the chassis rear component cover by loosening the screws on the corners of
1.
the cover and pulling it straight out from the chassis.
Remove the SFM, as described in the M40e and M160 router hardware guides.
2.
Take the SFM offline by using the
3.
command. You can also press and hold the offline button on the SFM faceplate at
the rear of the router until the SFM OK LED turns off (about 5 seconds).
Replace the SFM with one that you know works.
4.
Bring the SFM online. Press and hold the offline button on the SFM faceplate until the
5.
green OK LED lights (about 5 seconds). You can also use the
slot-number online command.
Reinstall the rear component cover and tighten the screws to secure it to the chassis.
6.
Check the SFM status. See
