4.Simultaneously rotate the ejector handles counterclockwise to unseat the SCB.

5.Grasp the ejector handles and slide the SCB about halfway out of the chassis.

6.Place one hand underneath the SCB to support it and slide it completely out of the chassis. Place it on the antistatic mat.

CAUTION: Do not stack hardware components on one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.

7.Repeat the procedure for the second SCB.

Removing DPCs

The router holds up to three DPCs, which are installed horizontally in the front of the router. A DPC weighs 13.1 lb (5.9 kg). Be prepared to accept its full weight.

To remove a DPC (see Figure 68 on page 191):

1.Have ready an antistatic mat for the DPC. Also have ready rubber safety caps for each DPC using an optical interface on the DPC that you are removing.

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. For more information about ESD, see “Preventing Electrostatic Discharge Damage” on page 130.

3.Simultaneously turn both the ejector handles counterclockwise to unseat the DPC.

4.Grasp the handles and slide the DPC straight out of the card cage halfway.

5.Place one hand around the front of the DPC and the other hand under it to support it. Slide the DPC completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.
