Removing the SSBs

The router can have an SSB in each of the two uppermost slots in the front of the chassis, as shown in Figure 1. Each SSB weighs approximately 3 lb (1.5 kg).

To remove the SSBs, follow this procedure (see Figure 32):

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. Loosen the thumbscrew at each end of the SSB, using a Phillips screwdriver if necessary.
4. Pull the end of each ejector lever outward until it is nearly perpendicular to the SSB faceplate.
5. Grasp the ejector levers and pull firmly to slide the SSB about halfway out of the chassis.
6. 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.
