Mounting an EX3300 Switch in a Recessed Position in a Rack or Cabinet

You can mount an EX3300 switch in a rack or cabinet such that the switch is recessed inside the rack from the rack front by 2 inches. You can use the 2-in.-recess front brackets provided in the separately orderable four-post rack-mount kit to mount the switch in a recessed position.

Reasons that you might want to mount the switch in a recessed position include:

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

  • The switch you are mounting has transceivers installed in the uplink ports—the transceivers in the uplink 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 EX3300 Switch on Four Posts in a Rack or Cabinet. To mount the switch in a recessed position on two posts, follow the instructions in Mounting an EX3300 Switch on Two Posts in a Rack or Cabinet.

Mounting an EX3300 Switch on a Wall

You can mount an EX3300 switch on a wall by using the separately orderable wall-mount kit.

Warning
  • When mounting an EX3300 switch chassis in a vertical position, orient the front panel of the chassis downward to ensure proper airflow and meet safety requirements in the event of a fire.

  • Install the wall-mount baffle above the units to reduce the risk of objects or substances falling into the air exhaust or power supply, which could cause a fire.

Before mounting the switch on a wall:

Ensure that you have the following parts and tools available:

  • 2 wall-mount brackets (provided in the wall-mount kit)

  • 12 wall-mount bracket screws (provided in the wall-mount kit)

  • 6 mounting screws (8-32 x 1.25 in. or M4 x 30 mm) (not provided)

  • Hollow wall anchors rated to support up to 75 lb (34 kg) if you are not screwing the screws directly into wall studs (not provided)

  • Phillips (+) screwdriver, number 2

To mount one or two switches on a wall:

  1. Remove the switch from the shipping carton (see Unpacking an EX3300 Switch).
  2. Attach the wall-mount brackets to the sides of the chassis using four wall-mount bracket screws on each side, as shown in Figure 8.
    Figure 8: Attaching Wall-Mount Brackets to a Switch Chassis
    Attaching
Wall-Mount Brackets to a Switch Chassis
  3. If you are mounting two switches together, align the second switch on top of the first in such a way that both the switches have airflow in the same direction and attach it to the mounting brackets using two additional wall-mount bracket screws on each side. (Figure 10 shows two aligned switches.)
  4. Install six mounting screws in the wall for the wall-mount brackets and baffle as shown in Figure 9:
    • Use hollow wall anchors rated to support up to 75 lb (34 kg) if you are not inserting the mounting screws directly into wall studs.

    • Turn the screws only part way in, leaving about 1/4 in. (6 mm) distance between the head of the screw and the wall.

    1. Install screw A.
    2. Install screw B 18.68 in. (47.4 cm) from screw A on a level line.
    3. Install screw C 5.98 in. (15.2 cm) on a plumb line down from screw A and screw D 5.98 in. down from screw B.
    4. Install screw E 2.76 in. (7 cm) up from and 8.32 in. (21.1 cm) to the right of screw A.
    5. Install screw F 4.49 in. (11.4 cm) to the right of screw E.
