Removing an SSB

To remove an SSB, follow this procedure (see Figure 63):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. 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.
3. If you are removing the active SSB, press and hold the offline button on the faceplate until the yellow LED labeled FAIL lights, which takes about 5 seconds.

   (The effect of removing the active SSB depends on whether a second SSB is installed. For more information, see Replacing an SSB.)

4. Loosen the thumbscrew at each end of the SSB, using a Phillips screwdriver if necessary.
5. Pull the end of each ejector lever outward until it is nearly perpendicular to the SSB faceplate.
6. Grasp the ejector levers and pull firmly to slide the SSB about halfway out of the chassis.
7. Place one hand under the SSB to support it, slide it completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.

   Caution: When an SSB is out of the chassis, do not hold it by the ejector levers. They cannot support its weight. Do not stack SSBs on top of or under other components. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
