Quick Start Description

This Quick Start contains information you need to install and configure the PTX3000. For complete

installation instructions, see the PTX3000 Packet Transport Router Hardware Guide at

https://www.juniper.net/documentation/.

WARNING: This Quick Start contains a summary of safety warnings in “Safety Warnings”

on page 42. For a complete list of warnings for the PTX3000, including translations, see

the PTX3000 Packet Transport Router Hardware Guide at

https://www.juniper.net/documentation/.

The PTX3000 is shipped in a wooden crate. A wooden pallet forms the base of the crate. The chassis is

bolted to this pallet. The shipping crate also contains an accessory box and this Quick Start

Step 1: Prepare the Site for the PTX3000

IN THIS SECTION

Rack-Mounting Requirements | 3

Tools Required to Unpack and Install the PTX3000 | 6

Before installing the PTX3000, make sure that the site meets all the power, environmental, and clearance

requirements. See the site preparation guidelines in the PTX3000 Packet Transport Router Hardware Guide.

Rack-Mounting Requirements

You can install the PTX3000 in many types of racks, including a four-post rack or cabinet or an open-frame

rack:

•The rack rails must be spaced widely enough to accommodate the chassis's external dimensions: 38.5 in.

(97.8 cm) high, 8.7 in. (22.1 cm) deep, and 17.6 in. (44.7 cm) wide. The cable management system on the

front of the chassis adds 1.9 in. (4.8 cm) to the depth, for a total depth of 10.6 in. (26.9 cm). The outer

edges of the mounting brackets extend the width to 19 in. (48.3 cm).

•The rack must be strong enough to support the weight of the fully configured PTX3000, up to about

310 lb (140.6 kg).

You must allow sufficient clearance around the rack:

•For the cooling system to function properly, the airflow around the chassis must be unrestricted.

•For service personnel to remove and install hardware components, there must be adequate space at the

front of the chassis. At least 24 in. (61.0 cm) is required in front of the PTX3000. NEBS GR-63 recommends

that you allow at least 30 in. (72.6 cm) in front of the rack.

•Additional clearance is required to accommodate the depth of the cable management system:

1.9 in. (4.8 cm) additional depth in the front of the chassis.

•The compact form-factor of the chassis allows up to four PTX3000 routers to be installed in a single

four-post rack. For all configurations, there must be at least 10 in. (25.4 cm) between the PTX3000 and

neighboring devices to the side, and there must be no obstruction above the chassis that prevents airflow.

Depending on your installation, the required clearance at the rear of the chassis varies:

•A standalone PTX3000 requires 2 in. (5.1 cm) of clearance at the rear (see Figure 1 on page 5).

•Two PTX3000 routers installed back-to-back require 4 in. (10.2 cm) of clearance between the routers

at the rear.

•Four PTX3000 routers installed back-to-back and stacked in a single rack require 10 in. (25.4 cm) of

clearance between the routers at the rear (see Figure 2 on page 6).

NOTE: These requirements have been designed to provide adequate cooling in deployments

with ambient temperatures up to 104°F (40°C).

Tools Required to Unpack and Install the PTX3000

Gather the tools required to unpack the PTX3000:

•Phillips (+) screwdriver, number 2

•1/2-in. or 13-mm open-end or socket wrench to remove bracket bolts from the shipping pallet

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)

Step 2: Unpack the PTX3000

For detailed instructions on how to unpack the shipping crate and verifying the parts received, see the

PTX3000 Packet Transport Router Hardware Guide.

Step 3: Install the PTX3000 Mounting Hardware

To install the mounting hardware, perform the following procedures:

1. Install Cage Nuts, If Needed | 7

2. Install the Mounting Shelf | 8

Install Cage Nuts, If Needed

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:

1. Insert cage nuts in the holes specified for the mounting shelf (see Table 1 on page 7).

NOTE: A mounting shelf is not required to install the PTX3000.

Install the Mounting Shelf

Optionally, you can install the mounting shelf before mounting the chassis in the rack. To install the

mounting shelf (see Figure 3 on page 8):

1. Align the mounting shelf with the mounting holes on the rack rail.

2. Partially insert a mounting screw appropriate for your rack into the holes specified in Table 1 on page 7.

3. Tighten all the screws completely to secure the mounting shelf to the rack rails.

Figure 3: Installing the Mounting Hardware

Step 4: Install the PTX3000

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 4 on page 11 and Figure 5 on page 12):

1. 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.

2. 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.

3. 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.

4. Install a mounting screw into each of the mounting holes aligned with the rack, starting from the bottom

(see Table 3 on page 10). 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.

5. Move the lift away from the rack.

6. If you are installing two to four routers in the rack, repeat this procedure for each router. See

Figure 6 on page 13 and Figure 7 on page 14 for examples of multiple routers installed in a single rack.
