Installing an SFM

To install an SFM, follow this procedure (see Figure 97):

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. Make sure the router is attached to a proper earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
2. Verify that the ends of the ejector handles are pulled outward to a position nearly perpendicular to the faceplate of the SFM.
3. Place one hand under the SFM to support it and grasp one of the ejector handles at the front with the other hand.
4. Align the rear of the SFM with the guides inside the chassis and slide it in completely.
5. Press the ejector handle at each end of the SFM inward.
6. Tighten the thumbscrew on each ejector locking tab (shown in Figure 8) to seat the SFM 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 SFMs.
