Removing the Chassis from the Equipment Rack

To remove the chassis from the equipment rack, follow these steps:

Step 1

Position the scissor-jack platform from the original router shipping package in front of the

rack-mounting platform in the rack.

Step 2

Use the 3/4-inch (19-mm) socket and ratchet wrench to turn the scissor-jack screw counterclockwise to

expand the scissor-jack platform and slowly raise the top of the scissor-jack platform to the same height

as the top of the rack-mounting platform. (See

Figure 6

Step 3

Working from the top of the chassis down, remove the screws that secure the chassis to the mounting

flanges on the rack (five screws on each side of the chassis). Set the screws aside for use in installing the

replacement chassis.

The chassis is still supported by the rack-mounting platform installed in the bottom of the rack, but

Caution

should be held to prevent the possibility of tipping out of the front of the rack.

Step 4

Position one person in front of the chassis to support and guide it while the second person slowly pushes

the chassis to slide it off the rack-mounting table, out of the rack, and onto the scissor-jack platform.

Step 5

With one person positioned on the side of the chassis to prevent it from tipping, install the four chassis

anchor clips through the slots in the bottom of the chassis, align the holes with the bolt holes in the

platform, and insert and tighten the four bolts to prevent the chassis from shifting on the scissor-jack

platform. (See
