Installing an SFM in an M40e Router

To install an SFM (see Figure 1):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series Router.
2. Verify that the ends of the ejector handles are pulled outward to a position nearly perpendicular to the faceplate of the SFM or CFEB-E.
3. Place one hand under the SFM or CFEB-E to support it and grasp one of the ejector handles at the front with the other hand.
4. Align the rear of the SFM or CFEB-E with the guides inside the chassis and slide it in completely.
5. Press the ejector handle at each end of the SFM or CFEB-E inward.
6. Tighten the thumbscrew on each ejector locking tab (shown in M40e SFM LEDs) to seat the SFM or CFEB-E firmly in the chassis.
7. Press the offline button on the SFM faceplate and hold it down until the green LED labeled OK lights steadily, in about 5 seconds.

   You can also verify correct SFM functioning by issuing the show chassis sfm commands described in Maintaining M40e SFMs.
