Installing the M120 Router Without Using a Mechanical Lift

If you cannot use a mechanical lift to install the router (the preferred method), you can
install it manually.
Before installing the router manually:
Read the safety information in "M120 Chassis Lifting Guidelines" on page 195.
1.
Prepare your site and review the guidelines in "M120 Site Preparation Checklist" on
2.
page 37
Remove the router from the shipping container as described in "Unpacking the M120
3.
Router" on page 44.
Install the mounting hardware as described in "Installing the Mounting Hardware for
4.
a Front-Mount Four-Post Rack or Cabinet" on page 49, "Installing the Mounting
Hardware for a Front-Mount Open-Frame Rack" on page 51, or "Installing the Mounting
Hardware for a Center-Mount Open-Frame Rack" on page 53.
Remove components from the chassis.
5.
To install the router in the rack (see Figure 34 on page 70):
CAUTION: If you are installing two or three routers in one rack, install the
lowest one first. Installing a router in the upper position in a rack or cabinet
requires a lift.
CAUTION: Before front mounting the router in a rack, have a qualified
technician verify that the rack is strong enough to support the router's weight
and is adequately supported at the installation site.
CAUTION: Lifting the chassis and mounting it in a rack requires three people.
The empty chassis weighs approximately 110 lb (49 kg).
Ensure that the rack is in its permanent location and is secured to the building. Ensure
1.
that the installation site allows adequate clearance for both airflow and maintenance.
For details, see "M120 Clearance Requirements for Airflow and Hardware Maintenance"
on page 41.
Position the router in front of the rack or cabinet, centering it in front of the mounting
2.
shelves. Use a pallet jack if one is available.
With one person on each side and one person in the front, hold onto the bottom of
3.
the chassis and carefully lift it onto the large and small (if installed) mounting shelves.
