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:

Insert cage nuts in the holes specified for the mounting shelf (see Table 1).
Note:
A mounting shelf is not required to install the PTX3000.

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:

Gather the tools and parts required to install the PTX3000 in a rack:
- Mechanical lift
- Screwdriver appropriate for your mounting screws (a number 1 Phillips (+) screwdriver is required for the mounting screws included in the accessory box
- Mounting screws appropriate for your rack (ten mounting screws are included in the accessory box)
- Cage nuts (if required for your rack or cabinet)
Read the safety information in General Safety Guidelines and Warnings and PTX3000 Installation Safety Guidelines.
Install the PTX3000 into the rack.
See Installing the PTX3000 in a Rack by Using a Mechanical Lift.

Installing the PTX3000 in a Rack by Using a Mechanical Lift

CAUTION:

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.

Note:

A mounting shelf is not required to install the PTX3000.

To install the PTX3000 by using a lift (see Figure 2 and Figure 3):

Load the PTX3000 onto the lift, making sure the PTX3000 rests securely on the mechanical lift.
CAUTION:
Do not lift the PTX3000 by using the handles on the front-mounting flanges. Use these handles only to help position the PTX3000.
Using the lift, position the PTX3000 in front of the rack. Lift the chassis slightly above the position you plan to install it, and position it as close as possible to the rack.
With two people in front, push the front-mounting flanges to slide the PTX3000 into the rack until the front-mounting flanges contact the rack rails. The front-mounting flanges of the chassis align with the holes in the rack rails.
Install a mounting screw into each of the mounting holes aligned with the rack, starting from the bottom (see Table 3). Use an appropriate screwdriver to tighten all the screws completely.
Visually inspect the alignment of the PTX3000. If the PTX3000 is installed properly in the rack, all the mounting screws on one side of the rack should be aligned with the mounting screws on the opposite side, and the PTX3000 should be level.
Move the lift away from the rack.
If you are installing two to four routers in the rack, repeat this procedure for each router. See Figure 4 and Figure 5 for examples of multiple routers installed in a single rack.
