Installing the PTX3000 Mounting Hardware
Installing Cage Nuts in the PTX3000 Rack
Insert cage nuts on the front rack rails, if needed. The hole distances are relative to the standard U division on the rack that is aligned with the bottom of the mounting shelf.
To install cage nuts on the front rack rails:

Installing the Mounting Shelf
Optionally, you can install the mounting shelf before mounting the chassis in the rack. To install the mounting shelf (see Figure 1):
- Align the mounting shelf with the mounting holes on the rack rail.
- Partially insert a mounting screw appropriate for your rack into the holes specified in Table 1.
- Tighten all the screws completely to secure the mounting shelf to the rack rails.

Overview of Installing a PTX3000 in a Rack
Before installing the PTX3000 in a rack, verify that you have prepared your site, unpacked the PTX3000 from the shipping crate, and installed the mounting hardware.
Because of the PTX3000 router’s size and weight—up to 310 lb (140.6 kg) depending on the configuration—you must install the PTX3000 by using a mechanical lift.
To install the PTX3000:
Installing the PTX3000 in a Rack by Using a Mechanical Lift
Before installing the PTX3000 router:
Verify that a mechanical lift is available for the installation.
Have a qualified technician verify that the rack is strong enough to support the chassis weight and is adequately supported at the installation site.
Ensure that the rack is in its permanent location and is secured to the building.
Ensure that the installation site allows adequate clearance for both airflow and maintenance.
A mounting shelf is not required to install the PTX3000.
