Rack Mounting the Switch

The following topics are covered in this section:
Note: Four-post rack mount is recommended for all switches. Use the rack-mount parts included with your switch for mounting.
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.

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

Two-Post Rack Mount

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.

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 1. Bracket Mount Examples for Two-Post Rack Mount
Note: Center mount is recommended, especially for heavier switches.

The following figure displays improper bracket mounts for two-post rack mount.

Figure 2. 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 figure shows the correct bracket attachment for a front mount.

3 Step 3    

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 (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.

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

Four-Post Rack Mount

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
  • 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.

The following figure displays proper bracket mount configuration examples for four-post mounting.

Attaching Mounting Brackets to the Chassis (Four-Post)

The following figure displays the front bracket alignment for mounting the switch into a four-post rack.
Figure 7. Attaching the Mounting Brackets to the Switch Chassis

This procedure attaches mounting brackets to the switch chassis as depicted by the preceding figure.

  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 8). 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.

Figure 8. Attaching the Four-Post Mounting Brackets to the Switch Chassis

2 Step 2 5 Bracket clip (aligned)
3 Step 3    

This procedure attaches the rails to a four post rack:

  1. Slide a rail-rod into a rail-slide (Figure 9) 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 9. Assembling the Rails

    2 Rail-rod    
    3 Rack plugs    
  2. Attach rail to the right rear rack post by inserting rod-end rack plugs into post slots (Figure 10). 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.
  4. Repeat Step 1 through Step 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 11. 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 12.
    Figure 12. Attaching the Switch to the Rack Posts

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