Rack Mounting the Switch

The Rack Mounting the Switch section reviews the following topics:
Note: The rack mounting procedure is identical for all switches covered by this guide. Illustrations in this chapter depict the mounting of a DCS-7010T-48 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-7010T-48.

Note: Illustrations use a representative Arista switch. Your device may be different in appearance.

Two-Post or Four-Post Rack Mount

The switch can be installed in a two-post or four-post rack. The installation process is identical because the switch attaches to only two posts of a rack.

To mount the switch in a rack, assemble the mounting brackets to the chassis, then attach the brackets to the rack posts. Rack mount accessory kits include the following parts:

  • 2 x mounting brackets

  • 6 x M4x5 flat head Phillips screws.

The following image displays the proper bracket placement for the rack mount.

Inserting the Switch into the Rack

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.

    After completing the rack mount, proceed to Cabling the Switch.

Four-Post Rack Mount

This section provides instructions for mounting the switch in a four-post rack.

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:
  • 2x six-hole mounting brackets
  • 2x rail-rods
  • 2x 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.

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 (Attaching the 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 located on both sides of the assembled rails, then install the rails with bolts that fit the rack.

2 Slide rail rod onto rail slide 5 Bracket clip (aligned)
3 Attach bracket clip    
  1. Slide a rail-rod into a rail-slide 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.

  2. Attach rail to the right rear rack post by inserting rod-end rack plugs into post slots. The slide assembly must be on the side of the post facing the switch.

    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.
  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

The appliance slides into the rack once the rails are installed. 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 10. 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 provided in the accessory kit.
