Removing the DPCs Before Installing an MX960 Router Without a Lift
To remove a DPC (see Figure 6):
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 an approved site ESD grounding point. See the instructions
for your site.
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.
CAUTION:
The weight of the DPC is concentrated in the back end. Be prepared to
accept the full weight—up to 13.1 lb (5.9 kg)—as you slide the DPC out of the chassis.
