Mounting Two 12-Port Switches in a Rack Side by Side

The 12-port 210 and 220 switch models are constructed so that two of them can fit side by side into a standard rack.

To mount two 12-port switches together in a rack, you will need the following equipment:

200-Series Dual Rack Mount Kit (separately orderable; part number 16572), which includes:
- Two short mounting brackets
- One long and two short middle-support brackets, for connecting the switches together
- Twenty bracket screws
Standard rack-mounting hardware (not included)
Screws for the rack-mounting hardware (not included)
No. 1 Phillips screwdriver for attaching bracket hardware (a magnetic screwdriver is recommended)
Flat-head screwdriver for mounting the switches in the rack

The instructions in this section pertain to the following switch models:

ExtremeSwitching 210-12t-GE2 switch
ExtremeSwitching 210-12p-GE2 switch
ExtremeSwitching 220-12t-10GE2 switch
ExtremeSwitching 220-12p-10GE2 switch

To mount the switches, follow these steps.

Place both switches on a flat, stable surface.
Attach mounting hardware to the first switch.
1. Using four chassis screws, attach a short bracket to the left side of the switch.
  See Dual-Mount: Attaching a Short Bracket to the First Switch.

2. Using four chassis screws, attach the long middle-support bracket to the right side of the switch.
  See Dual-Mount: Attaching the Long Middle-Support Bracket to the First Switch.

Attach mounting hardware to the second switch.
1. Using two chassis screws, attach a short middle-support bracket to the left side of the switch, at the front end.
  Position the bracket so that the tab end is toward the front of the switch. See Dual-Mount: Attaching the Middle-Support Brackets to the Second Switch.

2. Using two chassis screws, attach the other short middle-support bracket to the left side of the switch, at the rear.
  Position the bracket so that the tab end is toward the rear of the switch. See Dual-Mount: Attaching the Middle-Support Brackets to the Second Switch.
3. Using four chassis screws, attach a short mounting bracket to the right side of the switch, as shown in Dual-Mount: Attaching a Short Bracket to the First Switch.
Slip the short connecting brackets into both ends of the long connecting bracket.
Using the four remaining chassis screws, attach the connecting brackets to each other.
See Dual-Mount: Attaching the Connecting Brackets to Each Other. Be sure to attach both of the short connecting brackets to the long bracket, both on top and bottom.

The switches can now be handled as if they were a single unit, as shown in Two Switches Connected to Each Other for Dual Mounting.

Attach the switches to the rack using rack-mounting hardware (not provided).

After the switches are securely in place, install optional components using the instructions in Installing Optional Components.
