Quick Start Description

This Quick Start contains information you need to install and configure the PTX10016

router. For complete installation instructions, see the Packet Transport Router Hardware

Guide at http://www.juniper.net/techpubs/.

WARNING: This guide contains a subset of PTX10016 safety information. For

the complete list of safety warnings for the PTX10016 see the PTX10016

Hardware Guide see Packet Transport Router Hardware Guide at

http://www.juniper.net/techpubs/.

Step 1–Preparing the Site for the PTX10016

The PTX10016 is a rigid sheet-metal router-chassis that houses field replaceable units

(FRUs) such as control boards, Switch Interface Boards (SIBs), power supplies, fan trays,

and line cards. The router chassis ships in a cardboard box that has a two-layer wooden

pallet base. The router chassis is bolted to the pallet base. You can install a PTX10016

router in a standard 19 in. (48.26 cm) equipment rack by using the supplied rack-mounting

kit and the front-mounting bracket that is attached to the chassis.

Before you install the PTX10016, make sure the site meets all the power, cooling, and

clearance requirements.

•Rack-Mounting Requirements on page 2

•Clearance Requirements on page 3

•Cooling and Airflow Requirements on page 3

Rack-Mounting Requirements

The PTX10016 router chassis is designed to be installed in standard 19-in. wide four-post

racks that are spaced at 1 U (1.75 in. or 4.45 cm) increments.

You can stack one PTX10016 chassis at the bottom of a four-post rack if:

•The rack is 42 U or greater.

•The rack meets the strength requirements to support the weight.

•The facility can provide adequate power and cooling.

Before installing the chassis, ensure that:

•The rack rails are spaced widely enough to accommodate the router chassis’ external

dimensions. The outer edges of the front-mounting brackets extend the chassis width

to 19 in. (48.26 cm).

•The rack is strong enough to support the weight of the router and cabling.

•The spacing of rails and adjacent racks allows for proper clearance around the router

and rack.

PTX10016 Router Quick Start Guide

Clearance Requirements

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

unrestricted. You must allow sufficient clearance around the installed chassis for cooling

and maintenance (see Figure 1 on page 3).

For airflow

If you are mounting a PTX10016 in a rack with other equipment, ensure that the exhaust

from other equipment does not blow into the intake vents of the chassis.

Cooling and Airflow Requirements

The cooling system in a PTX10016 chassis consists of dual fan trays and dual fan tray

controllers. There is no air filter in a PTX10016.

The air intake to cool the chassis is located on the port (line card) side of the chassis. Air

flows into the chassis from the ports in the control boards and line cards, through the

Switch Interface Boards (SIBs), and exits from the fan trays and the power supplies. This

airflow is called port-to-FRU cooling or airflow out (AFO). See Figure 2 on page 4.

Clearance Requirements

Figure 2: Airflow Through a PTX10016

Follow these guidelines:

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

unrestricted.

•If you are mounting a PTX10016 in a rack with other equipment, ensure that the exhaust

from other equipment does not blow into the intake vents of the chassis.

•Leave at least 24 in. (61 cm) both in front of and behind the PTX10016 for service

personnel to remove and install hardware components. To be NEBS GR-63 compliant,

allow at least 30 in. (76.2 cm) in front of the rack and 24 in. (61 cm) behind the rack.

Step 2–Unpacking the PTX10016

NOTE: The chassis is maximally protected inside the shipping box. Do not

unpack it until you are ready to begin installation.

Ensure that you have the following parts and tools available to unpack the PTX10016:

•A 13/32 in. (10 mm) open-end or socket wrench to remove the bracket bolts from the

shipping pallet

PTX10016 Router Quick Start Guide

•A box cutter or packing knife to slice open the nylon straps and tape that seal the crate

and boxes

The chassis ships in a cardboard box that has a two-layer wooden pallet base with foam

cushioning between the layers. The router chassis is bolted to the pallet base.

The shipper has the option to either ship the front panel separately or to ship along with

the chassis. If the front panel arrives with the chassis, set aside the front panel box until

you are ready to verify the contents of the order.

Step 2–Unpacking the PTX10016

To unpack the chassis (see Figure 3 on page 6):

Figure 3: Shipping Crate and Accessory Box

1. Move the shipping box to a staging area as close to the installation site as possible.

While the chassis is bolted to the pallet, you can use a forklift or pallet jack to move

it. Make sure there is enough space to remove components from the chassis.

2. Position the shipping box with the arrows pointing up.

3. Slice the nylon straps with the box cutter that hold the shipping boxes to the pallet.

4. Lift the shipping box off the chassis.

PTX10016 Router Quick Start Guide

5. Remove the cardboard accessory box.

6. Remove the foam padding from the top of the box.

7. Remove the plastic cover from the router chassis.

8. Use a 13/32 in. (10 mm) open-end or socket wrench to remove the four sets of bracket

bolts that secure the chassis to the shipping pallet (see Figure 4 on page 7).

Figure 4: Bracket Bolt Removal

9. Unpack the accessory box and lay out the contents so that they are ready for use.

10. Verify that your order includes all appropriate parts.

11. Store the brackets and bolts inside the accessory box.

12. Save the shipping box and packing materials in case you need to move or ship the

router at a later time.

Step 2–Unpacking the PTX10016

Step 3–Mounting the Router Chassis

To install the PTX10016, first install the mounting hardware and then use a mechanical

lift to load the chassis into the rack.

•Installing the Mounting Hardware on page 8

•Mounting the PTX10016 Using a Mechanical Lift on page 10

Installing the Mounting Hardware

Install the mounting hardware on the rack before installing the router. The PTX10016

comes with a four-piece set of mounting brackets that support the chassis in the rack.

NOTE: Two-post installation racks are not supported.

The four mounting bracket pieces are:

•1 left front mounting bracket. The bracket is labeled “LEFT FRONT” on the side of the

bracket that faces the interior of the rack, near the holes for attaching the bracket to

the rack.

•1 right front mounting bracket. The bracket is labeled “RIGHT FRONT” on the side of

the bracket that faces the interior of the rack, near the holes for attaching the bracket

to the rack.

•2 rear mounting brackets. These brackets are labeled “REAR” on the side of the bracket

that faces the interior of the rack, near the holes for attaching the bracket to the rack.

The rear brackets are interchangeable; you can use either of the rear brackets with the

right or left front-mounting bracket.

Ensure that you have the following parts and tools available to install the mounting

brackets:

•A Phillips (+) screwdriver, number 1, 2, or 3, depending on the size of your rack-mounting

screws

•A Phillips (+) screwdriver, number 2, to install the screws that connect the

rear-mounting and front-mounting brackets

•16 mounting screws appropriate for your rack to attach the 4 mounting bracket pieces

to the rack

When you install the mounting brackets, the adjustable portion of the brackets overlap.

Use the overlap area to adjust the total bracket length to fit any of the four standard rack

sizes: 19 in. (483 mm), 23.62 in. (600 mm), 30 in. (762 mm), or 31.5 in. (800 mm).

PTX10016 Router Quick Start Guide

To install the mounting brackets in a four-post rack:

1. Remove the mounting brackets from the accessory box.

2. Decide where to place the chassis in the rack. If the rack is empty, mount the router

in the lowest possible location. See “Rack-Mounting Requirements” on page 2.

3. Position the left front adjustable mounting bracket at the desired position in the left

side of the rack and line up its front screw holes with the holes in the rack. Use four

mounting screws appropriate for your rack to attach the left front bracket to the rack.

4. Position one of the rear brackets at the left rear of the rack on the same level as the

left front bracket, so that the rear bracket overlaps with the left front bracket. The

screw holes for connecting the front and rear brackets should overlap. Use four

mounting screws appropriate for your rack to attach the rear bracket to the rack.

5. Connect left front and rear brackets (see Figure 5 on page 9):

a. Insert six of the screws provided with the mounting brackets into the overlapping

bracket holes.

b. Hand-tighten the screws fully (to 12–16 in.-lb torque) using a number 2 Phillips

screwdriver.

6. Position the right front adjustable mounting bracket at the desired position in the right

side of the rack opposite the installed left front bracket, so that it is on the same rack

Installing the Mounting Hardware

level as the left bracket. If the right and left front brackets are not on the same level,

the chassis will rest at an angle in the rack instead of resting flat and level. Line up the

right bracket's front screw holes with the holes in the rack. Use four mounting screws

appropriate for your rack to attach the right front bracket to the rack.

7. Position the other rear bracket at the right rear of the rack on the same level as the

right front bracket, so that the rear bracket overlaps with the right front bracket. The

screw holes for connecting the front and rear brackets should overlap. Use four

mounting screws appropriate for your rack to attach the rear bracket to the rack.

8. Connect the right front and rear brackets (see Figure 5 on page 9):

a. Insert six of the screws provided with the mounting brackets into the overlapping

bracket holes.

b. Hand-tighten the screws fully (to 12–16 in.-lb torque) using a number 2 Phillips

screwdriver.

Mounting the PTX10016 Using a Mechanical Lift

Because of the router's size and weight, the PTX10016 can safely be installed only by

using a mechanical lift.

CAUTION: Do not install line cards in the chassis until after you mount the

chassis securely on a rack or cabinet.

CAUTION: Before front-mounting the router on a rack or cabinet, have a

qualified technician verify that the rack or cabinet is strong enough to support

the router's weight and is adequately supported at the installation site.

Ensure that you have the following parts and tools available to install the router:

•A mechanical lift rated for 1000 lbs. (453.6 kg)

•12 mounting screws appropriate for your rack

•A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your

rack-mounting screws

CAUTION: If you are installing more than one router in a rack or cabinet, install

the first router at the bottom of the rack.
