To mount one or two switches on a wall:
1. Remove the switch from the shipping carton (see “Unpacking an EX3300 Switch” on
page 82).
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 29 on page 93.

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 31 on page 94 shows two aligned switches.)
4. Install six mounting screws in the wall for the wall-mount brackets and baffle as
shown in Figure 30 on page 94:
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.
a. Install screw A.
b. Install screw B 18.68 in. (47.4 cm) from screw A on a level line.
c. 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.
d. Install screw E 2.76 in. (7 cm) up from and 8.32 in. (21.1 cm) to the right of screw A.
