Table 2. Facility requirements (continued)
Type Requirements
Rack (when
rack-mounted) Ensure that these airflow requirements are met:
v Plan to install the device with the air-intake side facing the cool
air aisle. The device can be installed facing either direction if
serviceability and cooling requirements are met.
v Ensure that the airflow available at the air vents meets the
minimum requirements for the device.
v Install the device with the airflow aligned with other devices in
the rack. Some devices have airflow running from port side to
nonport side and others have the opposite arrangement. Make
sure that the airflow for all devices moves in the same direction
to maximize cooling.
Ensure that the following amount of space is available in the rack:
v 14 rack units (14U) high. 1U is equal to 4.45 cm (1.75 inches).
v 61.29 cm (24.09 inch) deep.
v 43.74 cm (17.22 inch) wide.
Ensure that the rack meets these additional requirements:
v Additional weight of chassis will not exceed the rack’s weight
limits.
v The rack is secured to ensure stability in case of unexpected
movement.
Time and items required for installation
You can set up and install the device in the following ways:
v As a standalone unit on a flat surface.
v In a 19-inch Electronic Industries Association (EIA) rack or in a
telecommunications (Telco) rack using a rack mount kit. Refer to“Mounting
options” on page 17 for applicable rack mount kits.
The following table describes the main installation and setup tasks, the estimated
time required for each, and the items required to complete the task for a device
that is fully populated with port blades. Configurations with fewer blades or ports
require less time. These time estimates assume a prepared installation site and
appropriate power and network connectivity.
