Attaching the Switch to a Four-Post Rack

A four-post rack-mounting kit is included in the box with your switch. The kit contains an instruction sheet, along with the following components:
  • Two mounting brackets, known as inner member in the instruction sheet. These pieces attach directly to both sides of the switch housing.
  • Two slider assemblies, one for each side of the switch. Each slider assembly consists of an outer piece that is secured to the rack and a sliding rail to which you will attach the corresponding mounting bracket. These pieces are known on the instruction sheet as the outer member and intermediate member.
  • Mounting ears - Black rack ears with a thumb screw in the middle (2 count)
  • Black mounting ear screws (4 count)

To attach your switch to a four-post rack, follow these steps:

  1. On the sides of switch, locate and remove the 2 black screws next to the data ports of the switch. Repeat as needed for the other side.
  2. Using the provided mounting ear screws, attach each of the mounting ears using the holes exposed in the previous step. The mounting ears should be flush with the faceplate of the switch.
    See Attaching a Mounting Bracket to One Side of the Switch Housingfor the correct orientation.
  3. Extend the slider assemblies to the full extent. Locate the small white release tab on the mounting bracket, and push it toward the blue release tab, allowing the mounting bracket to slide the rest of the way off the slider assemblies. Repeat for the other slider assembly.
  4. Attach a mounting bracket to one side of the switch housing.
    Snap the mounting bracket onto the housing. Then anchor it in place using the screws provided. See Attaching a Mounting Bracket to One Side of the Switch Housing.
