Port Exhaust Kit Installation Procedure 3 of 20
Publication Number: 53-1001181-04
Air flows into the Brocade DCX-4S Backbone through its non-port side and out through the exhaust vent on the side
of the unit, The Port-Side Exhaust Mount Kit is designed to route this airflow out the exhaust vents on the port side of
the unit while mounted in the equipment cabinet. This document provides instructions to install a Brocade DCX-4S
Backbone in a 19 in. (48.26 cm) Electronic Industries Association (EIA) cabinet using the following Brocade Port-Side
Exhaust Mount Kits:
•Kit for cabinet rail-to-rail depth of 27 to 31 in. (68.58 to 78.74 cm).
•Kit for cabinet rail-to-rail depth of 18 to 24 in. (45.72 to 60.96 cm).

Safety
Observe the caution notice in this manual. The caution notice has an ID, which is displayed in parentheses (C015).
Use this ID to locate the translation of this caution notice in the Brocade Product Safety Notices.
CAUTION
Use safe lifting practices when moving the product. (C015)
NOTE
A fully populated Brocade DCX-4S weighs 103.50 kg (228.20 lb) with four FC8-48 port cards installed (192 ports) and
requires a hydraulic or assisted lift to install it.
Installation guidelines
ATTENTION
To ensure adequate cooling, install the chassis with the air intake (nonport side) facing the cool-air aisle.
Follow these general installation guidelines:
•The shelf in the kit is 1 U high, so you need a total of 9 U of cabinet space to install the shelf and the Brocade
DCX-4S Backbone. 1U is equal to 4.45 cm (1.75 in.).
•To allow the quick removal of all power from the chassis, use AC power sources that are easily accessible and
located near the chassis.
•Verify that the additional weight of the chassis does not exceed the weight limits of the cabinet.
•Plan for cable management before installing the chassis. Cables can be managed in a variety of ways, such as
by routing cables below the chassis, to either side of the chassis, through cable channels on the sides of the
cabinet, or using patch panels. Refer to the product’s DCX-4S Backbone Hardware Reference Manual for
specific information.

•Ensure that one or two dedicated electrical branch circuits with the following characteristics are available:
-200-240 VAC, 50-60 Hz (refer to the corresponding Hardware Reference Manual for additional electrical
specifications)
-Protected by a circuit breaker in accordance with local electrical codes
-Supply circuit, line fusing, and wire size are adequate, according to the electrical rating on the chassis
nameplate
-Grounded outlets are installed by a licensed electrician and compatible with the power cords
-Located close to the enterprise-class platform chassis and easily accessible
•To maximize fault tolerance, connect each power cord to a separate power source.
•Ensure that all equipment installed in the cabinet is grounded through a reliable branch circuit connection. Do
not rely on a secondary connection to a branch circuit, such as a power strip.
•Ensure that the product fans have access to a total minimum airflow of 350 cubic ft (9.91 cubic meters) per
minute. Do not block intake vents. Allow for a minimum of 14 in. (35.66 cm) clearance.
•Ensure that the air temperature on the air intake side is less than 104oFahrenheit (40oCelsius) during
operation.

location.
2. Use a pallet jack or other assisted lift to transport the new chassis to the installation area. Doorways must be
wider than 36 in. (91 cm) to accommodate the chassis on the pallet.
3. Remove the Port-Side Exhaust kit, accessory kit, packing foam, and antistatic plastic from the chassis and set
aside.

Torque requirements
Use the following torque settings when tightening screws that secure the rack mount kit and DCX-4S to the
equipment cabinet.
Install cabinet hardware
1. Determine how the DCX-4S can be oriented in the equipment cabinet so that the nonport side has access to
intake air (cool).
2. Install clip nuts (F in Figure 1 on page 6) or retainer nuts (G in Figure 1 on page 6) in cabinet rail locations shown
in Figure 2 on page 7. These nuts will secure the 10-32 screws that mount the Port Side Exhaust Kit shelf and
DCX-4S to the cabinet. For rails with round holes, use clip nuts. For rails with square holes, use retainer nuts.
Note that Figure 2 on page 7 shows relative positions for these nuts in the cabinet rails to mount the shelf and
DCX-4S. You may mount the shelf and DCX-4S in 9 U of cabinet space higher or lower in the cabinet than shown.

3. Install the shelf (C in Figure 1):
a. The shelf can be adjusted to a length of between 27 and 31 inches (68.58 and 78.74 cm) to accommodate
your cabinet size. To lengthen or shorten the shelf, loosen the four 6-32 screws in the four slots on the shelf
(I-4 through I-7 in Figure 1 on page 6) and adjust the shelf to the desired length. Once adjusted, tighten the
four 6-32 screws.
b. Secure the shelf to the cabinet with eight 10-32 screws with washers (E in Figure 1 on page 6), two screws
in each corner of the shelf (see Figure 3). Tighten screws according to specifications under “Torque
requirements” on page 7.

approximately the length of the adjustable shelf. Once adjusted, tighten the two 6-32 screws.
b. Insert the top-rail assembly down into the air-duct assembly and then secure the top-rail assembly to the
air-duct assembly with two 6-32 screws, one screw on each side of the air-duct assembly (I-1 and I-2 in
Figure 1 on page 6). Tighten screws according to specifications under “Torque requirements” on page 7.
