Use the following steps to install a QFX10008.
Step 1–Preparing the Site for the QFX10008
The QFX10008 is a rigid sheet-metal switch-chassis that houses the other hardware
components such as control boards, switch interface boards (SIBs), power supplies, fan
trays, and line cards. The switch chassis ships in a cardbox box that has a two-layer
wooden pallet base. The switch chassis is bolted to the pallet base. You can install a
QFX10008 switch in a standard 19 in. (483 mm) equipment rack by using the supplied
rack-mounting kit and the front-mounting bracket that is attached to the chassis.
Before you install the QFX10008, make sure the site meets all of the power, cooling, and
clearance requirements. See the site preparation guidelines and power requirements in
the QFX10008 Switch Hardware Guide
•Rack-Mounting Requirements on page 2
•Clearance Requirements on page 3
•Cooling and Airflow Requirements on page 3
Rack-Mounting Requirements
The QFX10008 switch 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 three QFX10008 chassis in 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.

QFX10008 Switch Quick Start Guide

•Ensure that the rack rails are spaced widely enough to accommodate the switch chassis’
external dimensions. The outer edges of the front-mounting brackets extend the chassis
width to 19 in. (48.26 cm).
•Ensure that the rack is strong enough to support the weight of the switch and cabling.
•Ensure that the spacing of rails and adjacent racks allows for proper clearance around
the switch and rack.
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).
Figure 1: Clearance Requirements for Airflow and Hardware Maintenance
for a QFX10008
If you are mounting a QFX10008 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 QFX10008 chassis consists of dual fan trays and dual fan tray
controllers. There is no air filter in a QFX10008.
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 QFX10008
Follow these guidelines:
•For the cooling system to function properly, the airflow around the chassis must be
unrestricted.
•If you are mounting a QFX10008 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 QFX10008 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 QFX10008
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 QFX10008:
•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 switch 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 3 on page 5):
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.
5. Remove the cardboard accessory box.
6. Remove the foam padding from the top of the box.
7. Remove the plastic cover from the switch 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 6).

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
switch at a later time.
Step 3–Mounting the Switch Chassis
To install the QFX10008, first install the mounting hardware and then perform one of
these two procedures:
•Installing the Mounting Hardware on page 6
•Mounting the QFX10008 Using a Mechanical Lift on page 8
•Manually Mounting a QFX10008 on page 11
Installing the Mounting Hardware
Install the mounting hardware on the rack before installing the switch. The QFX10008
comes with a four-piece set of mounting brackets that supports the chassis in the rack.
NOTE: Two-post installation racks are not supported.

QFX10008 Switch Quick Start Guide

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).
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 switch
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 8):
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
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 8):
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 QFX10008 Using a Mechanical Lift
Because of the switch's size and weight, we strongly recommend using a mechanical lift
to install the QFX10008.
CAUTION: Do not install line cards in the chassis until after you mount the
chassis securely on a rack or cabinet.

QFX10008 Switch Quick Start Guide

CAUTION: Before front-mounting the switch on a rack or cabinet, have a
qualified technician verify that the rack or cabinet is strong enough to support
the switch's weight and is adequately supported at the installation site.
Ensure that you have the following parts and tools available to install the switch:
•A mechanical lift rated for 500 lbs. (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 switch in a rack or cabinet,
install the first switch at the bottom of the rack.
To install the switch using a mechanical lift (see Figure 6 on page 10):
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 “Cooling and Airflow Requirements” on
page 3.
2. Load the switch onto the lift, making sure it rests securely on the lift platform.

3. Using the lift, align the switch in front of the rack, centering it in front of the mounting
brackets.
4. Lift the chassis approximately 0.75 in. (1.9 cm) above the surface of the mounting
brackets. Align the chassis as close as possible to the mounting brackets.
5. Carefully slide the chassis onto the adjustable mounting brackets until the
front-mounting brackets attached to the chassis contact the rack rails. The mounting
brackets ensure that the holes in the front-mounting brackets align with the holes in
the rack rails. See Figure 7 on page 11.
