Rack Mounting the Switch

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.

 

 

Note: Use the rack-mount parts included with your switch for mounting. For heavier switches, only a four-post mount is supported.

 

 

Note: A 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 incompatible, leading to the inability to properly mount or remove a switch from the rack.

 

 

After completing the instructions for your rack type, proceed to Cabling the Switch.

Two-Post Rack Mount

Discusses two-post rack mounting options.

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.

 

Goupilles de fixation doivent être bloquer tous les trois trous de la bride supérieure.

Figure 3. Attaching the Mounting Brackets to the Switch Chassis (Front 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 differ from two-post mounting ears and should not be used for two-post mounting.

This procedure attaches mounting brackets to the switch chassis as depicted by Figure 3 - Attaching the Mounting Brackets to the Switch Chassis (Front Mount)Attaching the Mounting Brackets to the Switch Chassis and Figure 4 - Attaching the Mounting Brackets to the Switch Chassis (Center Mount).

  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.
    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).

     

Inserting the Switch into the Rack

This procedure attaches the switch to the rack (Figure 5 - Inserting the Switch into the Rack (Front Mount)).

  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.

    After completing the two-post rack mount, proceed to Cabling the Switch.

Four-Post Rack Mount

Discusses the four-post racking option.

The switch is mounted onto a four-post rack by assembling two rails onto the rear posts, sliding the switch onto the rails, and securing the switch to the front posts.

The installation kit provides the following four-post mounting parts:
  • 2 six-hole mounting brackets
  • 2 rail-rods
  • 2 rail-slides

     

The rail rods and rail slides assemble into two identical slide rails.

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.

This procedure attaches mounting brackets to the switch chassis as depicted by Figure 9 - Attaching the Mounting Brackets to the Switch Chassis (Front Mount)Attaching the Mounting Brackets to the Switch 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.
    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).

     

Assembling the Rails onto the Equipment Rack

Rail rods and rail slides assemble into two identical rails. Each rail connects a front post to a rear post. When the rails are installed, the switch slides on the rails into the rack. Each bracket includes a screw that attaches the switch to the rail.

Each end of an assembled rail contains two rack plugs (Figure 10 - Attaching the Four-Post Mounting Brackets to the Switch Chassis). The rails are installed into a rack by inserting the plugs into rack slots. When installing rails into posts with threaded or rounded holes, remove all plugs on both sides of the assembled rails, then install the rails with bolts that fit the rack.

 

Figure 10. Attaching the Four-Post Mounting Brackets to the Switch Chassis

1 Step 1 2 Step 2 3 Step 3
4 Bracket clip (attached) 5 Bracket clip (aligned)    

 

This procedure attaches the rails to a four-post rack:

  1. Slide a rail rod into a rail slide (Figure 11 - Assembling the Rails) until the rail clip makes an audible click.

    The rail clip prevents the extension of the rail beyond the maximum supported distance between the front and rear rack posts.

     

    Figure 11. Assembling the Rails

    3 Rack plugs 4 Rail (assembled)

     

  2. Attach the rail to the right rear rack post by inserting rod-end rack plugs into post slots (Attaching the Rails, Detail A). The slide assembly must be inside the right posts relative to the left rack posts.

    If the rack plugs were previously removed, use bolts to attach the rail to the rack.

     

  3. Attach the slide end of the rail to the front post by extending the rail end past the post, then contracting the rail while guiding the rack plugs into the post (Attaching the Rails, Detail B).
  4. Repeat Step 1 through 3 for the left posts. Ensure the rails are on the same horizontal level.

Attaching the Switch to the Rack

After the rails are installed, the switch slides on the rails into the rack. Each bracket includes a thumb screw that attaches the switch to the rail.

  1. Lift the switch into the rack and insert the mounting brackets into the slide rails.

     

    Figure 13. Inserting the Switch onto the Rails

     

  2. Slide the switch on the rails toward the rear posts until the mounting bracket flanges are flush with the rail flanges attached to the rack posts.
  3. Attach the bracket flanges to the rack post using the quick-release thumb screws supplied with the brackets (Figure 14 - Attaching the Switch to the Rack Posts).
