DRAFT: BROCADE CONFIDENTIAL
3. In an two-post Telco rack using the mid-mount rack kit for switches. The mid-mount rack
kit for switches can be ordered from your switch retailer.
4. In an EIA rack using a four-post sliding rail rack kit. The sliding rail rack mount kit can be
ordered from your switch retailer.
Electrical considerations
To install and operate the switch successfully, ensure the following:
•
The primary outlets are correctly wired, protected by a circuit breaker, and grounded in
accordance with local electrical codes.
•
The supply circuit, line fusing, and wire size are adequate, as specified by the electrical
rating on the switch nameplate.
•
The power supply standards provided in Table 1 , “Power Supply Specifications” are met.
Power supply specifications
The power supplies are universal and capable of functioning worldwide without voltage jumpers or
switches. They meet IEC 61000-4-5 surge voltage requirements and are autoranging in terms of
accommodating input voltages and line frequencies. Each power supply has built-in fans for
cooling.
Table 1 lists the power supply specifications for the Brocade 6520.
Environmental considerations
For successful installation and operation of the switch, ensure that the following environmental
requirements are met:
•
At a minimum, adequate cooling requires that you install the switch with the intake side,
as indicated by the airflow direction of the fan assemblies, facing the cool-air aisle.
•
All equipment in the rack should force air in the same direction to avoid intake of exhaust
air.
•
A maximum of 102 cubic meters/hour (60 cubic feet/minute) and a minimum of 74.8
cubic meters/hour (44 cubic feet/minute) of air flow is available for air intake.
