Appendix C Cabinet and Rack Installation
Cabinet and Rack Requirements
•
A recommended cabinet depth of 36 to 42 inches (91.4 to 106.7 cm) to allow the doors to close and
adequate airflow.
•
Bottom of cabinet should be open to enhance airflow.
•
The lowest piece of equipment should be installed a minimum of 1.75 inches (4.4 cm) above the
floor openings to prevent blocking the floor intake.
Solid-Walled Cabinet Requirements for the Cisco MDS 9509 and the Cisco MDS 9506 Chassis
The solid-walled cabinet requirements for the Cisco MDS 9509 and the Cisco MDS 9506 chassis are as
follows:
•
A roof-mounted fan tray and an air cooling scheme in which the fan tray pulls air in at the bottom
of the cabinet and exhausts it out the top, with a minimum of 500 cfm of airflow exiting the cabinet
roof through the fan tray.
•
Nonperforated (solid and sealed) front and back doors and side panels so that air travels predictably
from bottom to top.
•
A recommended cabinet depth of 36 to 42 inches (91.4 to 106.7 cm) to allow the doors to close and
adequate airflow.
•
A minimum of 150 square inches (968 sq. cm) of open area at the floor air intake of the cabinet.
•
The lowest piece of equipment should be installed a minimum of 1.75 inches (4.4 cm) above the
floor openings to prevent blocking the floor intake.
Requirements Specific to Standard Open Racks
In addition to the requirements listed in the
“General Requirements for Cabinets and Racks” section on
page C-1
, if mounting the chassis in an open rack (no side panels or doors), ensure that the rack meets
the following requirements:
•
The minimum width between two front mounting rails must be 17.75 inches (45.1 cm).
•
The minimum vertical rack space per chassis:
–
Cisco MDS 9513 chassis: 24.5 inches (62.2 cm) or 14 RU.
–
Cisco MDS 9509 chassis: 24.5 inches (62.2 cm) or 14 RU.
–
Cisco MDS 9506 chassis: 12.25 inches (31.1 cm) or 7 RU.
Note
The rack-mount support brackets provided with the Cisco MDS 9513 Director require an
additional height of 0.75 inches (1.9 cm). They are required during the installation of the Cisco
MDS 9513 Director and cannot be removed.
Note
The side rail-mount brackets provided with the Cisco MDS 9509 Director require an additional
height of 0.75 inches (1.9 cm). They are required during the installation of the Cisco MDS 9509
Director only, and can be removed or left installed once the front rack-mount brackets are
securely fastened to the rack-mounting rails.
Note
The Cisco MDS 9506 Director does not require shelf brackets.
