4. Mount the switch. Unplug the AC or DC power from the switch before mounting it.
Rack Mounting: Use a #1 Phillips (cross-head) screwdriver to attach the accessory kit brackets to the switch using the
eight 8-mm M4 screws. Then use the four number 12-24 screws to secure the brackets to the rack.
Table or Desktop Mounting: Attach the four self-adhesive
pads (included in the accessory kit) to the bottom corners of
the switch.
Wall or Under-table Mounting: To mount the 1820-24G,
1820-24G-POE+, 1820-48G, and 1820-48G-POE+ switches,
Use a #1 Phillips (cross-head) screwdriver and attach the
mounting brackets to the switch with the included 8-mm M4
screws. Attach the switch to the wall or wood surface with two
5/8-inch number 12 wood screws (not included).
To mount the 1820-8G and 1820-8G-POE+ switches, mark the
position for the mounting screws. The hole-to-hole distance is
3.54 inch (90-mm). Use a #1 Phillips (cross-head) screwdriver
and two of the included 20-mm 4 tap screws. Set the screw
heads approximately 2 mm away from the mounting surface to
allow the switch to slide on to the screws. Wall anchors are
included in the accessory kit for use with plastered brick or
concrete walls.
For under-table mounting, a third 20-mm M4 tap screw can be
placed against one side of the switch to secure it in place.
IMPORTANT: Wall-mount the switch with network ports
facing up or down (away from or toward the floor). Do not
wall-mount the switch with the ventilation holes facing up or
down. (See "Installation Precautions" (page 5))
5. Power on the switch.
