Mounting an EX4550 Switch

You can mount an EX4550 switch:

  • Flush with the rack front on two posts of a 19-in. two-post or four-post rack or cabinet by using the mounting brackets provided with the switch.

  • Flush with the rack front on four posts of a 19-in. four-post rack or cabinet by using the separately orderable four-post rack-mount kit.

  • In a position recessed 2 in. (5 cm) from the front of a 19-in. two-post or four-post rack or cabinet by using the separately orderable four-post rack-mount kit.

The holes in the mounting brackets are placed at 1 U (1.75 in. or 4.45 cm) apart so that the switch can be mounted in any rack or cabinet that provides holes spaced at that distance.

See the Related Documentation for detailed descriptions of the various rack or cabinet mounting options.

Mounting an EX4550 Switch on Two Posts in a Rack or Cabinet

You can mount an EX4550 switch on two posts in a 19-in. rack or cabinet (either a two-post or a four-post rack or 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 in a four-post rack by using the mounting brackets provided with the separately orderable four-post rack-mount kit. See Mounting an EX4550 Switch on Four Posts in a Rack or Cabinet.

Note

If you need to mount the switch in a recessed position on two posts of 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 shipped with the switch)

  • Screws to secure the chassis to the rack (not provided)

  • 2-in.-recess front mount brackets if you will mount the switch in a recessed position (brackets are part of the separately orderable four-post rack-mount kit).

  • Cover panels for module slots (provided in the accessory box shipped with the switch)

  • Dust covers for ports (provided in the accessory box shipped with the EX4550-32F switches)

Note

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

Caution

If you are mounting multiple switches on a rack, mount a switch in the bottom of the rack first and proceed to mount the rest of the switches from bottom to top.

To mount the switch on two posts in a rack:

  1. Place the switch on a flat, stable surface.
  2. Place the mounting brackets along the side panels of the switch chassis, aligning them with the rear panel, the front panel, or with the center of the side panels depending on how you want to mount the switch. See Figure 1.

Mounting an EX4550 Switch in a Recessed Position in a Rack or Cabinet

You can mount an EX4550 switch in a recessed position on two posts of either a two-post rack or a four-post rack such that the switch is recessed inside the rack from the rack front by 2 inches. To mount the switch in a recessed position, use the front mount brackets provided in the separately orderable four-post rack-mount kit.

Reasons to mount the switch in a recessed position include:

  • You are mounting the switch in a cabinet and the cabinet doors do not close completely unless the switch is recessed.

  • The switch you are mounting has an expansion module with transceivers installed in it—the transceivers in the expansion module ports protrude from the front of the switch.

To mount the switch in a recessed position on four posts, follow the instructions in Mounting an EX4550 Switch on Two Posts in a Rack or Cabinet or Mounting an EX4550 Switch on Four Posts in a Rack or Cabinet.
