Preparation
The following topics are covered in this section:
Site Selection
Tools and Parts Required for Installation
Electrostatic Discharge (ESD) Precautions
2.1 Site Selection
The following criteria should be considered when selecting a site to install the switch.
Temperature and Ventilation: For proper ventilation, install the switch where there is ample
airflow to the front and back of the switch. The ambient temperature should not go below 0° or
exceed 40°C.
Important: To prevent the switch from overheating, do not operate it in an area where the
ambient temperature exceeds 40°C (104°F).
Pour empêcher l’interrupteur de surchauffe, ne pas utiliser il dans une zone où la
température ambiante est supérieure à 40°C (104°F).
Airflow Orientation: The fans and PSUs determine the airflow direction through the switch. The
color of the visible handles or labels indicate the airflow direction.
Note: The figures shown use representative Arista switches to illustrate airflow directions.
Refer to Rear Panel to determine the airflow for your switch.

Red Handle: Air Exit module. The following figure shows the airflow through the switch with
air exit modules:
Figure 2: Air Exit Module
Orient the switch such that the airflow through the switch is from the cooler to the hotter aisle.
If the airflow direction is not compatible with the installation site, reorient the fan modules to
circulate air in the opposite direction.
Rear Panel displays fan and power supply module locations on the rear panel. Red handles indicate
that they are air exit modules. Verify that each module has the same airflow direction. Base the
switch orientation on the airflow direction of the modules to assure the air inlet is always oriented
toward the cool aisle:
Air Exit modules: orient the rear panel toward the hot aisle.
Air Inlet modules: orient the rear panel toward the cool aisle.
If the airflow direction is not compatible with the installation site, contact your sales representative to
obtain modules that circulate air in the opposite direction.
Rack Space: Install the switch in a 19" rack or cabinet. The switches covered by this guide
may be 1 RU or 2 RU in height. The accessory kit provides approved mounting brackets for the
system. Four-post mounting is recommended for all systems. Where 2-post parts are supplied,
they are intended for center-mounting the device.
When mounting the switch in a partially filled rack, load the rack from bottom to top, with the heaviest
equipment at the bottom. Load the switch at the bottom if it is the only item in the rack.
Power Requirements: Power requirements vary by switch and power supply model. Table 3:
Switch Specifications (Power Input) and Table 4: Switch Specifications (Power Draw) provide
information regarding your specific system.
Two circuits provide redundancy protection. Cabling the Switch describes power cable
requirements.
Note: Handle or label color indicates airflow direction.
Important: The power input plug-socket combination must be accessible at all times; it
provides the primary method of disconnecting power from the system.
La combinaison de la puissance-prise d’entrée doit être accessible en tout temps ; Il
fournit le principal moyen de coupure d’alimentation du système.
Other Requirements: Select a site where liquids or objects cannot fall onto the equipment and
foreign objects are not drawn into the ventilation holes. Verify these guidelines are met:
10
Preparation
Clearance areas to the front and rear panels allow for unrestricted cabling.
All front and rear panel indicators can be easily read.
Power cords can reach from the power outlet to the connector on the rear panel.
Important: All power connections must be removed to de-energize the unit.
Toutes les connexions d’alimentation doivent être enlevées pour hors tension
l’appareil.
2.2 Tools and Parts Required for Installation
Each switch provides an accessory kit that contains parts that are required to install the switch.
In addition to the accessory kit, the following tools and equipment are required to install the switch:
Two-Post Rack
Screws or rack mounting nuts and bolts.
• Screwdriver
Four-Post Rack (Tool-less)
No additional equipment required.
Four-Post Rack (Conventional)
Screws or rack mounting nuts and bolts.
• Screwdriver
Accessory kit does not include screws for attaching the switch to the equipment rack. When
installing the switch into an equipment rack with unthreaded post holes, nuts are also required to
secure the switch to the rack posts.
2.3 Electrostatic Discharge (ESD) Precautions
Observe these guidelines to avoid ESD damage when installing or servicing the switch.
Assemble or disassemble equipment only in a static-free work area.
Use a conductive work surface (such as an anti-static mat) to dissipate static charge.
Wear a conductive wrist strap to dissipate static charge accumulation.
Minimize handling of assemblies and components.
Keep replacement parts in their original static-free packaging.
Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.
Use tools that do not create ESD.

Rack Mounting the Switch
Rack Mounting the Switch (1RU)
The following topics are covered in this section:
Two-Post Rack Mount (1RU)
Note: Use the rack-mount parts included with your switch for mounting. For heavier
switches, only a four-post mount is supported.
Attaching Mounting Brackets to the Chassis (Two-Post)
Inserting the Switch into the Rack (Two-Post)
Four-Post Rack Mount (1RU)
Attaching Mounting Brackets to the Chassis (Four-Post)
Assembling the Rails onto the Equipment Rack
Attaching the Switch to the Rack
Note: Four-post rack mount is recommended for all switches. Use the rack-mount parts
included with your switch for mounting. Rails from different kit SKUs may look similar but
could be incompatible leading to the inability to properly mount or remove a switch from the
rack.
The following sections detail rack mounting in two-post and four-post racks for 1 RU switches.
Important: The rack mounting procedure is identical for all switches covered by this guide.
Illustrations in this chapter depict the mounting of a DCS-7050QX-32S switch.
Les procédure de montage du bâti est identique pour tous les commutateurs visés
par ce guide. Illustrations dans ce chapitre montrent le montage d’un interrupteur de
DCS-7050QX-32S.
Two-Post Rack Mount (1RU) provides instructions for mounting the switch in a two-post rack.
Four-Post Rack Mount (1RU) provides instructions for mounting the switch in a four-post rack.
After completing the instructions for your rack type, proceed to Cabling the Switch.
3.1 Two-Post Rack Mount (1RU)
To mount the switch onto a two-post rack, assemble the mounting brackets to the chassis, then
attach the brackets to the rack posts. Two-post accessory kits include the following two-post
mounting parts.
2 - Three-hole Mounting Brackets
Each chassis side has attachment pins that align with bracket holes. Pin orientation is symmetric
and equidistant, supporting bracket placements where the flange is flush with the front switch panel,
flush with the rear panel, or not flush with either panel. Each bracket hole includes a key-opening for
placing the bracket flush with the chassis and then locking it into place.
Important: Attachment pins must engage all three upper bracket holes.
Les goupilles de fixation doivent être bloquées tous les trois trous de la bride supérieure.

3.1.1 Attaching Mounting Brackets to the Chassis (Two-Post)
The following figure displays the front bracket alignment for attaching the switch into a two-post rack.
Figure 3: Bracket Mount Examples for Two-Post Rack Mount
Note: Deep and heavy devices could droop and cause damage to the equipment rack if front
or rear mounted. Arista recommends only center mounting for switches covered in this guide
when two-post mounting is required, and the switch accessory kit includes two-post mounting
ears. Four-post mounting ears are different from the two-post mounting ears and should not
be used for two-post mounting.
The following figure displays examples of improper bracket mounts for two-post rack mount.
Figure 4: Improper Bracket Mount Examples for Two-Post Rack Mount
The following procedure attaches the two-post rack mount brackets to the chassis.
1. Align the mounting brackets with the attachment pins to obtain the desired mounting position.
2. Place the bracket flush on the chassis with attachment pins protruding through key-openings.
3. Slide the bracket toward the front flange until the bracket clip locks with an audible click.

The following figures show the correct bracket attachment for a center mount.
Figure 5: Attaching the Mounting Brackets to the Switch Chassis
To remove the mounting bracket from the chassis, lift the front edge of the mounting bracket clip with
a flathead screwdriver and slide the bracket away from the front flange (opposite from the installation
direction).
3.1.2 Inserting the Switch into the Rack (Two-Post)
This procedure attaches the switch to the rack.
1. Lift the chassis into the rack. Position the flanges against the rack posts.
2. Select mounting screws that fit your equipment rack.
3. Attach the bracket flanges to the rack posts.
Figure 6: Inserting the Switch into the Rack
After completing the two-post rack mount, proceed to Cabling the Switch.
3.2 Four-Post Rack Mount (1RU)
The switch is mounted onto a four-post rack by assembling two rails onto the rear posts, sliding the
switch onto the rails, then securing the switch to the front posts.
The installation kit provides the following four-post mounting parts:
2 six-hole mounting brackets
15
2 rail-rods
2 rail-slides
The rail-rods and rail-slides assemble into two identical slide-rails.
Note: For longer chassis, there are two additional pieces to help the switch engage with the
rails earlier.
Each chassis side has attachment pins that align with bracket holes. Pin orientation is symmetric
and equidistant, supporting bracket placements where the flange is flush with the front switch panel,
flush with the rear panel, or not flush with either panel. Each bracket hole includes a key-opening for
placing the bracket flush with the chassis and then locking it into place.
Important: Attachment pins must engage at least five of the six bracket holes.
Goupilles de fixation doivent être lock au moins cinq des trous du six support.
The following figure displays proper bracket mount configuration examples for four-post mounting.
