Rack Mounting the Switch
- Two-Post Rack Mount
Note: Use the rack-mount parts included with your switch for mounting. For heavier switches, only four-post mount is supported.
- Four-Post Rack Mount
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 provides instructions for mounting the switch in a two-post rack.
- Four-Post Rack Mount provides instructions for mounting the switch in a four-post rack.
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.
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.

The following procedure attaches the two-post rack mount brackets to the chassis.
- Align the mounting brackets with the attachment pins to obtain the desired mounting position.
- Place the bracket flush on the chassis with attachment pins protruding through key-openings.
- 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.

2 | Step 2 | 5 | Bracket clip (aligned) |
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.
- Lift the chassis into the rack. Position the flanges against the rack posts.
- Select mounting screws that fit your equipment rack.
- 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.
- 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.
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)
![](/assets/images/qsg/qsg-7280-series-1ru-gen3/Graphics/Rack%20Mounting%20the%20Switch/Illus_516_resize.png)
This procedure attaches mounting brackets to the switch chassis as depicted by the preceding figure.
- Align the mounting brackets with the attachment pins to obtain the desired mounting position.
- Place the bracket flush on the chassis with attachment pins protruding through key-openings.
- 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.

This procedure attaches the rails to a four post rack:
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.
- Lift the switch into the rack and insert the mounting brackets into the slide rails.
Figure 11. Inserting the Switch onto the Rails
- 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.
- Attach the bracket flanges to the rack post using the quick-release thumb screws supplied with the brackets Figure 12.
