Type Requirements
Device specifications
Ensure that the facility can accommodate the system, power, and environmental specifications for
this device as outlined in the Technical Specifications .
Electrical Ensure that there are dedicated electrical branch circuits with the following characteristics available:
•
Four branch circuits to power supplies for high availability and maximum blade usage.
•
Four cables for VAC high-line or VAC low-line operation.
•
Two cables for DC operation.
•
Circuit breaker protection in accordance with local electrical codes.
•
Supply circuit, line fusing, and wire size adequate to the electrical rating on the chassis
nameplate.
•
An easily accessible location close to the chassis.
•
Grounded outlets installed by a licensed electrician and compatible with the power cords.
Ensure that all equipment in the rack is grounded through a reliable branch circuit connection.
Make sure that power distribution units (PDUs) can handle the maximum input amperage of the
power supplies. Use cables with an adequate amperage rating from the PDUs to the power source.
Thermal Ensure that the air intake and exhaust vents have a minimum of 5.1 cm (2 in.) of air space.
Ensure that the air intake temperature is less than 40°C (104°F) during operation.
Rack (when rack-mounted) Ensure that the following airflow requirements are met:
•
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.
•
Ensure that the airflow available at the air vents meets the minimum requirements for the device.
•
Install the device with the airflow aligned with other devices in the rack. Some devices have
airflow running from the port side to the 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:
•
14 rack units (14U) high. 1U is equal to 4.45 cm (1.75 in.).
•
61.29 cm (24.09 in.) deep.
•
43.74 cm (17.22 in.) wide.
Ensure that the rack meets the following additional requirements:
•
The additional weight of the chassis does not exceed the weight limit of the rack.
•
The rack is secured to ensure stability in case of unexpected movement.
Time and Items Required
You can set up and install the device in the following ways:
•
As a stand-alone unit on a flat surface.
•
In a 19-in. Electronic Industries Association (EIA) rack or in a telecommunications (Telco) rack using a Brocade rack
mount kit. See Mounting Options for applicable rack mount kits.
The following table describes the main installation and setup tasks, the estimated time that is required for each, and the
items that are required to complete the tasks 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.
