Installation Process Orientation For 1.5U 16-port switches, see Figure 2.
The current or planned configuration of rack components
2
determines which installation process orientation to follow. A
key consideration is whether the cables are routed at the front
or rear of the rack.
General rack configuration guidelines include:
For RETMA 41U and metric SW600 racks, follow Uppe
r loca
procedures as oriented from the rack-front. tion
Lowe
For RETMA 42U and Compaq Classic racks, either r loca
tion
orientation--rack-front or rack-rear--configuration is
possible. Install as desired.
Beginning the Installation Process
If available, use the rack-mounting template shipped with the
8- or 16-port switch to determine the installation location CXO7518A
within the rack. Otherwise, read this section and mark rail
holes as required, using a mounting bracket.
For 2U 16-port switches, see Figure 3.
IMPORTANT: Ensure that the template-front and back are used according
to the desired installation orientation. In rack-front installations, the
template-front is used at the rack-front and template-back is used at the
3
rack-rear. In rack-rear installations, the template-front is used at the
rack-rear and template-back is used at the rack-front.
1. Position the template-front on the vertical rails to match the
template hole pattern to the rail holes.
For 8-port switches, see Figure 1.

CXO6804C
2. Pencil-mark the front mounting bracket holes with an M.
3. Position the template-back on the rack-rear vertical rails,
aligning the template parallel with the rack-front pencil
markings.
4. Pencil-mark the rear mounting bracket holes with an M.

(10-32 x 5/8 inches).
WARNING: To reduce the risk of personal injury or equipment
damage during installation, never extend multiple
5
components installed in the rack at the same time. A rack
may become unstable if more than one component is
extended for any reason.
RETMA 41U Racks
1. Position each mounting bracket (see Figure 4, 1) with the
rail holes pencil-marked M.
IMPORTANT: Finger-tighten all three mounting bracket screws to
facilitate alignment. Then secure screws in the top and bottom
mounting bracket holes prior to securing the single screw at the rear of
the bracket. Ensure that the mounting bracket is parallel in the rack
from front to back. CXO6784B
2. Install a clip nut 2 and secure, using pan head SEMS
screws (10-32 x 5/8 inches). 2. Position each mounting bracket behind the vertical rail,
aligning it with the rail holes pencil-marked M.
3. Secure each mounting bracket using alignment washers and
4 pan head SEMS screws (10-32 x 5/8 inches) as shown in
Figure 6.
IMPORTANT: Position each alignment washer to mate smoothly against
the vertical rail prior to fully tighting the screw.

4. Fully tighten the four screws installed in step 1 (see
Figure 5).
IMPORTANT: To establish full strength of the extended bracket, ensure
that screws bonding the mounting bracket and extender bracket are
fully tightened prior to proceeding.

Attaching the Slide Brackets
Secure two slide brackets to each switch.
-- For cable-rear installations, attach the brackets as
shown in Figure 10.
CAUTION: Ensure that the mounting screws are the proper length
and that flat washers are used. Installing screws longer than 9/32
inch or without a flat washer may damage the switch.

For older 8-port switches (380591B21/ DSDSGGAAA)
in rack-front and rear installations, see Figure 8.
Use four pan head SEMS screws (10-32 x 9/32 inches) and
four flat washers to attach the mounting brackets to the
switch.
IMPORTANT: Attach the slide brackets using a flat washer with each
screw. Without the flat washers, the screws contact with the power
supply assembly inside the switch chassis.

Figures 11 and 12), or one inch from the rack-front for
cable-rear installations (see Figures 13 and 14).

Use four pan head SEMS screws (10-32 x 9/32 in) and four
flat washers to attach the mounting brackets to the switch.
NOTE: Install this 16-port switch with the cables at either the front or
the rear of the rack.
This switch is 1.5U (1.75 in) in height and may be installed in pairs,
using a second universal mounting kit to occupy a 3U space in the rack.
References to upper and lower location--the top 1.5U or bottom
1.5U--are used to indicate the placement of the switch within a 3U
space. Mount the switch so that no gap exists between the switch and
the nearest enclosure.

-- For rack-front installations, attach the brackets as
shown in Figure 15. IMPORTANT: All switches use the same cable routing method, so a
representative example is used here to illustrate this process.
Insert the switch slide brackets into the rack mounting brackets

Routing Power and Data Cables
IMPORTANT: All switches use the same cable routing method, so a
representative example is used here to illustrate this process.
Install a snap-on cable tie into each slide bracket, as shown in
Figure 19 (representative example), as desired, and route the
power cables downward along the rack vertical rail. Route data
cables based upon the current or planned rack configuration.
