Publication Number: 53-1003114-02
Introduction
Air flows into the Intake Air Duct Kit through the front vent and out through the fans at the rear of the unit. This
document provides instructions to install a Intake Air Duct Kit in a 19 in. (48.26 cm) Electronic Industries Association
(EIA) rack in either a flush or recessed configuration using the following Brocade Intake Air Duct Kit.
• Flush mount kit for rack rail-to-rail depth of 27 to 31 in. (68.58 to 78.74 cm).
• Recessed kit for rail-to-rail depth of 27 to 31 in. (68.58 to 78.74 cm)
This Intake Air Duct Kit, with improved airflow over the previous kit, is required for the following and later-model line
cards:
• 48x10GT
• 27x40GbE
• 6x100GbE

safe lifting practices when moving this product.
Installation guidelines
ATTENTION
To ensure adequate cooling, install the switch with the air intake (port side) facing the cool-air aisle.
Follow these general installation guidelines:
• The shelf in the kit is 2U high, so you need a total of 10U of rack space to install the shelf and the Intake Air Duct
Kit. 2U is equal to 8.90 cm (3.50 in.).
• Allow for an additional 1U rack space above the switch for installing the top intake assembly onto the side duct.
This will provide clearance to raise the intake assembly up and insert into the side duct tabs (refer to step 5b
under
“Installing the flush mount Intake Air Duct kit” and “Installing the recessed mount Intake Air Duct kit” .)
• To allow the quick removal of all power from the switch, use AC power sources that are easily accessible and
located near the switch.
• Verify that the additional weight of the switch does not exceed the weight limits of the rack.
• Plan for cable management before installing the switch. Cables can be managed in a variety of ways, such as by
routing cables to either side of the switch, through cable channels on the sides of the rack, or using patch
panels. Refer to the Brocade VDX 8770-4 Hardware Reference Manual for specific information.
