Installing an SSB

To install an SSB, follow this procedure (see Figure 64):

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. Verify that 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 levers are pulled outward to a position nearly perpendicular to the faceplate of the SSB.
3. Place one hand under the SSB to support it and grasp one of the ejector levers at the front with the other hand.
4. Align the rear of the SSB with the guides inside the chassis and slide it in completely.
5. Press the ejector lever at each end of the SSB inward.
6. Tighten the thumbscrew at each end of the SSB to seat the SSB firmly in the chassis.
7. Press the offline button on the SSB faceplate and hold it down until the green LED labeled ONLINE lights steadily, in about 5 seconds.

   You can also verify correct SSB functioning by issuing the show chassis ssb commands described in Maintaining the SSBs.
