Figure 31: Removing the Cable Management System Before Installing the
M120 Router
The router holds up to four FPCs, which are installed vertically in the front of the router.
An empty FPC weighs 9.0 lb (4.0 kg). A fully configured FPC can weigh up to
12.3 lb (5.6 kg).
Each FPC slot not occupied by an FPC must be covered by an FPC blank panel. An FPC
blank panel weighs 7.7 lb (3.5 kg).
To remove an FPC (see Figure 32 on page 67):
Place an electrostatic bag or antistatic mat on a flat, stable surface.
1.
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.
Before removing the FPCs, record their location in the chassis so that you can reinstall
3.
each FPC in the correct slot.
Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.
4.
Grasp the handles and slide the FPC straight out of the card cage halfway.
5.
Place one hand around the front of the FPC (the PIC housing) and the other hand

under it to support it. Slide the FPC completely out of the chassis, and place it on the
antistatic mat or in the electrostatic bag.
