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-7020SR-32C2 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-7020SR-32C2.

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, attach the mounting ears to the chassis, then attach the ears to the rack posts. Two-post accessory kit includes 2x mounting ears as two-post mounting parts.

 

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

This procedure attaches mounting brackets to the switch chassis as depicted by Figure 1.

 

  1. Align the mounting brackets with the sides of the chassis.
  2. Use the screws to attach the brackets to the chassis.
    Figure 1. Attaching Mounting Brackets to the Switch Chassis

    Note: DCS-7020SR-32C2 supports front mount only.

Inserting the Switch into the Rack

This procedure attaches the switch to the rack (Figure 3-2).
  1. Lift the chassis into the rack. Position the mounting ears against the rack posts.
    Note: The mounting ears should be at the same height to ensure that the device is level.
  2. Select mounting screws that fit your equipment rack.
  3. Attach the mounting ears to the rack posts.

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

Four-Post Rack Mount

Note: For DCS-7020SR-32C2, four-post rack kits are optional and sold separately.

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:

  • 2x mounting brackets
  • 2x rail-rods
  • 2x rail-slides

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

Attaching Mounting Brackets to the Chassis

This procedure attaches mounting brackets to the switch chassis as depicted by Figure 1.
  1. Align the mounting brackets with the sides of the chassis.
  2. Use the screws to attach the brackets to the chassis.

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 4). 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 4. Attaching the Mounting Brackets to the Switch Chassis

This procedure attaches the rails to a four post rack:

  1. Slide a rail-rod into a rail-slide (Figure 5) until the rail clip makes an audible click.
    Note: 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 (Figure 6). The slide assembly must be inside the right posts, relative to the left rack posts.
    Note: 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 (Figure 6).
  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 7).
    Figure 7. 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 8).

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