Mounting an EX3300 Switch on Two Posts in a Rack or Cabinet

You can mount the switch on two posts of a 19-in. rack (either a two-post or a four-post rack) or a 19-in. cabinet by using the mounting brackets provided with the switch. (The remainder of this topic uses “rack” to mean “rack or cabinet”.)

You can mount the switch on four posts of a four-post rack by using the mounting brackets provided with the separately orderable four-post rack-mount kit. See Mounting an EX3300 Switch on Four Posts in a Rack or Cabinet.

Note: If you need to mount the switch in a recessed position on either a two-post rack or a four-post rack, you can use the 2-in.-recess front mount brackets provided in the separately orderable four-post rack-mount kit.

Before mounting the switch on two posts in a rack:

Ensure that you have the following parts and tools available:

  • Phillips (+) screwdriver, number 2
  • 2 mounting brackets and 8 mounting screws (provided in the accessory box in the switch carton)
  • Screws to secure the chassis to the rack (not provided)
  • 2-in.-recess front brackets from the separately orderable four-post rack-mount kit if you will mount the switch in a recessed position

Note: One person must be available to lift the switch while another secures the switch to the rack.

Caution: If you are mounting multiple units on a rack, mount the heaviest unit at the bottom of the rack and mount the other units from the bottom of the rack to the top in decreasing order of the weight of the units.

To mount the switch on two posts in a rack:

  1. Remove the switch from the shipping carton (see Unpacking an EX3300 Switch).
  2. Place the switch on a flat, stable surface.
  3. Align the mounting brackets along the front or rear of the side panels of the switch chassis depending on how you want to mount the switch. For example, if you want to front-mount the switch, align the brackets along the front of the chassis. See Figure 22.

    Note: If you need to mount the switch in a recessed position, use the 2-in.-recess front mount brackets from the separately orderable four-post rack-mount kit.

  4. Align the bottom holes in the mounting brackets with holes on the side panels of the switch chassis.
  5. Insert the mounting screws into the aligned holes. Tighten the screws.
  6. Ensure that the other holes in the mounting brackets are aligned with the holes in the side panels. Insert a screw in each hole and tighten the screws.
  7. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the mounting bracket holes with the threaded holes in the rack or cabinet rail. Align the bottom hole in each mounting bracket with a hole in each rack rail, making sure the chassis is level. See Figure 23.

  8. Have a second person secure the switch to the rack by using the appropriate screws. Tighten the screws.
  9. Ensure that the switch chassis is level by verifying that all screws on one side of the rack are aligned with the screws on the other side.
