Installation Process Orientation
The current or planned configuration of rack components
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
procedures as oriented from the rack-front.
• For RETMA 42U and Compaq Classic racks, either
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
within the rack. Otherwise, read this section and mark rail
holes as required, using a mounting bracket.
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
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.
• For 1.5U 16-port switches, see Figure 2.
• For 2U 16-port switches, see Figure 3.
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.

Attaching the Mounting Brackets
Attach two mounting brackets, using the appropriate procedu re
for the rack type.
WARNING: To reduce the risk of personal injury or equipment
damage during installation, never extend multiple
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.
2. Install a clip nut 2 and secure, using pan head SEMS
screws (10-32 x 5/8 inches).
RETMA 42U and Compaq Classic Racks
1. Connect an extender bracket to each mounting bracket (see
Figure 5) and finger-tighten two 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 u sing alignment washers and
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.

Metric Racks
1. Position each mounting bracket (see Figure 7, 1) with the
rail holes pencil-marked M.
2. Identify clip nut 2 mounting holes and install two clip nuts
for each mounting bracket.
3. Secure each mounting bracket, using pan head SEMS
screws (10-32 x 5/8 inches).
Attaching the Slide Brackets
Secure two slide brackets to each switch.
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 swit ches (380591–B21/ DS–DSGGA–AA)
in rack-front and rear installations, see Figure8.
Use four pan head SEMS scre ws (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.
• For newer 8-port switches
(176219–B21/DS–DSGGC–AA), see Figures 9 and 10.
Use four pan head SEMS screws (8-32 x 1/4 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 may contact components
inside the switch chassis.
NOTE: Install this 8-port switch with the cables at either the front or the
rear of the rack.
— For cable-front installations, attach the brackets as
shown in Figure 9.
— For cable-rear installations, attach the brackets as
shown in Figure 10.

• For 1.5U 16-port switches (such as 212776–B21/
DS–DSGGC–AB)—Positioned approximately three inches
from the rack front for cable-front installations (see
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 scre ws (1 0-32 x 9/3 2 in) and fo ur
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 cable-front installations in an upp er lo cation, attach
the brackets as shown in Figure 11.
— For cable-front installations in a lower location, attach
the brackets as shown in Figure 12.
— For cable-rear installations in an upper location, attach
the brackets as shown in Figure 13.
— For cable-rear installations in a lower location, attach
the brackets as shown in Figure 14.

• For 2U 16-port switches (such as 380578–B21/
DS–DSGGA–AB) in rack-front and rack-rear installations,
see Figures 15 and 16.
Use four pan head SEMS scre ws (10 -32 x 9/32 inches) and
four flat washers to attach the mounting brackets to the
switch.
— For rack-front installations, attach the brackets as
shown in Figure 15.
— For rack-rear installations, attach the brackets as shown
in Figure 16.
Installing the Switch into the Rack
CAUTION: Keep the switch parallel to the floor while sliding the
slide brackets into the mounting brackets. Tilting the switch up or
down may result in damage to the brackets.
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 r ack moun ting brackets
until fully seated, and secure the front and rear, using pan head
SEMS screws (10-32 x 5/8 inches).
• Secure the front of the switch as shown in Figure 17
(representative example).
• Secure the rear of the switch as shown in Figure 18
(representative example).

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 downw ard along the rack ver tical rail. Route data
cables based upon the current or planned rack configuration.
This completes the hardware installation.
