Removing an MX10008 Router From a Four-Post Rack Using a Mechanical
Lift
Because of the router's size and weight, we strongly recommend using a mechanical lift to install the
MX10008.
NOTE: For instructions on installing a router without using a mechanical lift, see “Manually Mounting
an MX10008 in a 4-Post Rack” on page 147 .
Before you remove the router using a lift:
•
Ensure that the rack is stable and secured to the building.
•
Ensure there is enough space to place the removed router in its new location and along the path to the
new location. See “MX10008 Clearance Requirements for Airflow and Hardware Maintenance” on
page 98 .
•
Review “General Safety Guidelines and Warnings” on page 313 .
•
Review the chassis lifting guidelines described in “MX10008 Chassis Lifting Guidelines” on page 319 .
•
Ensure that the router has been safely powered off (see “Powering Off an MX10008 Router” on page 272 ).
CAUTION: When removing more than one router chassis from a rack, remove the routers
in order from top to bottom.
Ensure that you have the following parts and tools available to remove the router:
•
A mechanical lift rated for 500 lb (226.8 kg)
•
A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your mounting screws
To remove the router using a mechanical lift (see Figure 160 on page 276 ):
1. Use the appropriate Phillips (+) screwdriver to remove the 14 mounting screws that attach the chassis
flange to the rack.
2. Move the lift to the rack and position it so that its platform is centers about 0.5 in. (1.27 cm) below the
bottom of the router chassis and as close to it as possible.
