Rack-Mount Requirements | 2

Power Requirements | 2

Cooling and Maintenance Requirements | 3

Before you install the PTX10008, make sure the site meets all of the rack, power, cooling, and clearance requirements.

Rack-Mount Requirements

The PTX10008 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 a maximum of three PTX10008 chassis in a four-post rack if:

•The rack is 42 U or greater.

•The rack meets the strength requirements to support the weight of the chassis and the cabling. A single PTX10008

chassis without optics and cabling can range from 145.2 lb (65.86 kg) to 421.25 lb (191.07 kg).

•The facility has adequate cooling and power to support additional systems.

Power Requirements

The PTX10008 router is available in AC, DC, high voltage AC (HVAC) and high voltage DC (HVDC) power configurations.

Each configuration has different power supplies, power cables, and cooling requirements. The power configuration and

the number of line cards you are installing determine your power requirements for the system. A procedure to determine

these power requirements is available in the PTX10008 Packet Transport Hardware Guide.

Cooling and Maintenance Requirements

For the cooling system to operate properly, you must allow sufficient clearance around the installed chassis for cooling

and maintenance (see Figure 1 and Figure 2 for a top view of clearance for the PTX10008. The cooling system in a

PTX10008 chassis consists of dual fan trays and dual fan tray controllers. Systems with 14.4 Tbps line cards require

addition air volume and use the JNP10008-FAN2 and JNP10008-FTC2 fans and fan tray controllers.

If you are mounting a PTX10008 in a rack with other equipment, ensure that the exhaust from other equipment does not

blow into the intake vents of the chassis.

The air intake to cool the chassis is located in the vents of the line cards and Routing and Control Boards (RCBs). Air flows

passes from the line cards and RCBs, through the switch interface boards (SIBs), and exists from the fans trays and the

power supplies. This airflow is called port-to-FRU cooling or airflow out (AFO). See Figure 3.

Step 2–Unpacking the PTX10008

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 PTX10008:

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

•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.

To unpack the chassis (see Figure 4):

Figure 4: 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.

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 5).

Figure 5: Bracket Bolt Removal

9. Unpack any items that shipped separately, such as an RCB, SIB, or line cards.

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

11. Verify that your order includes all appropriate parts.

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

13. Save the shipping box and packing materials in case you need to move or ship the router at a later time.

Step 3–Mount the Chassis in the Rack

1. Install the Mounting Hardware | 7

2. Mount the PTX10008 in a 4-Post Rack Using a Mechanical Lift | 9

Install the Mounting Hardware

To install the chassis, first install the mounting hardware in the rack and then mount the PTX10008 in the rack.

The router can be installed in a four-post closed frame rack or a four-post open frame rack. Install the mounting hardware

on the rack before installing the router.

To mount the chassis on a four-post rack, you must first install the mounting hardware in the rack. The PTX10008 router

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

NOTE: Two-post installation racks are not supported.

The main pieces of the rack mount kit are:

•One left base 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.

•One right base 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.

•Two rear 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 base bracket.

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

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

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

•12 Phillips flat-head screws (provided)

•14 rack screws appropriate for your rack to attach the mounting hardware to the rack (not provided)

When you install the base and rear 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).

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

1. Remove the mounting brackets from the rack mount kit box.

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

3. Position the left base 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 base 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 base bracket, so that the rear

bracket overlaps with the left bracket. The screw holes for connecting the base and rear brackets should overlap. Use

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

5. Connect left base bracket and rear brackets (see Figure 6):

a. Insert six of the flat-head screws provided with the mounting brackets into the overlapping bracket holes.

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

Figure 6: Mounting Brackets for Four-Post Rack Installation

g050603

2—1—Rear bracketsRight and left base brackets

6. Position the right base bracket at the desired position in the right side of the rack opposite the installed left base

bracket, so that it is on the same rack level as the left base bracket. If the right and left base 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 base bracket's

front screw holes with the holes in the rack. Use four mounting screws appropriate for your rack to attach the right

base bracket to front of the rack.

7. Position the other rear bracket at the right rear of the rack on the same level as the right base bracket, so that the rear

bracket overlaps with the right base bracket. The screw holes for connecting the base 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 base and rear brackets (see Figure 6):

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.

Mount the PTX10008 in a 4-Post Rack Using a Mechanical Lift

Because of the router's size and weight, we strongly recommend using a mechanical lift to install the PTX10008. If you

do not have a mechanical lift available, see the alternative instructions for manual mounting in the PTX10008 Packet

Routing Hardware Guide.

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 500 lb (226.8 kg)

•14 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.

To install the router using a mechanical lift (see Figure 7):

1. Ensure that the rack or cabinet is placed in its permanent location and is secured to the building. Ensure that the

installation site allows adequate clearance for both airflow and maintenance. For details, see .

2. Load the router onto the lift, making sure it rests securely on the lift platform.

Figure 7: Loading the PTX10008 into a Rack Using a Mechanical Lift

3. Using the lift, align the router in front of the rack, centering it in front of the base brackets.

4. Lift the chassis approximately 0.75 in. (1.9 cm) above the surface of the base brackets. Align the chassis as close as

possible to the base brackets.

5. Carefully slide the chassis onto the adjustable base and rear mounting brackets until the chassis flanges contact the

rack rails. The mounting brackets ensure that the holes in the flanges align with the holes in the rack rails. See Figure 8.
