Device Placement Requirements
The DS-16M2 switches must be located at the top of the rack/cabinet,
because the power cord routing for these switches runs across the top
of the uppermost switch. There are no restrictions on the location of
the DS-32M2 switches in the rack/cabinet.
Power distribution must support the number of outlets required for
the switch and the switch power rating listed in the table on page 2.

Installing the DS-16M and DS-32M Rails
DS-16M Rails Installation
There are two different length rails: The short rails range between
20.5 inches to 27 inches. The long rails range from 27 inches to 34
inches. Each kit contains two different length rear rail mounts. Use
the rail length that is appropriate for your rack/cabinet.
The front and rear flanges of the DS-16M rails have three screw holes.
See the figure below.
If you are installing both a DS-16M2 and DS-32M2 switch, the DS-16M2
should be positioned at the top of the rack/cabinet, located above the
DS-32M2 switch.
Select the appropriate length rails, and follow the steps below to
install them.

Installing the DS-16M and DS-32M Rails
1. Assemble the rails.
The rails assembly consists of an adjustable rail, a C channel, and
two washers and kep nuts. See the figure below.
a. Insert the threaded posts on the C channel into the slot on the
adjustable rail.
b. Secure the adjustable rail to the C channel with two #10 flat
washers and M5 kep nuts. Leave the nuts finger tight.
2. Determine where in the rack/cabinet you are going to locate the
switch.
The left/right orientation of the rails is determined by the
location of the word “top” on the C channel. The rail is oriented
correctly when this word “top” is up and toward the rack/cabinet
front. See the next figure.

3. Adjust the length of the rail to fit between the channels in the
rack/cabinet.
NOTE: The rail flanges go to the inside of the channels.
4. Once the rails are adjusted to the correct length, tighten the kep
nuts on the rail assembly.
NOTE: If the side skins are removed on the rack/cabinet, you can tighten
the kep nuts after you install the rails.
5. Align the holes of the front rail flange to the inside of the front
channel. The top and bottom screw holes are used for the screws;
the center screw hole is used for the ball stud or latch bracket.
6. Secure the rail to a round-hole channel with 2 M5 x 12 mm
pan-head screws (see the table on page 3), or secure the rail to a
square-hole channel with 2 square-hole washers and
"Top" up and to the
rack front
Flange to the inside
of the channel (rack front)

Installing the DS-16M and DS-32M Rails
M5 x 16 mm flat head screws (see the table on page 3). Leave the
screws finger-tight, and tighten them after the switch is installed.
See the figure below.
If you are installing the switch in a 40U cabinet, install a keyplate spacer on
the outside of the channel as you secure the rail to the front channel. The
spacer is marked such that an L or an R will be upright when correctly
installed on the left or right channel. See the figure below.

7. If you are installing the switch in a 39U cabinet, position the #10
washer and ball stud in the center hole, between the two
M5 x 12 mm screws. Hand-tighten the ball stud.
NOTE: The ball studs support the bezel.
If you are installing the switch in a 40U cabinet, use an M5 x 12 mm
screw to install the latch bracket in the center hole, over the
keyplate spacer. See the figure below.
8. Align the holes in the rear, u-shaped flange of the rail with the
holes in the rear inside channel.
