Site preparation and installation guidelines
The following steps are required to ensure correct installation and operation.
1. Provide a space that is 2 rack units (2U) high. 1U is equal to 4.45 cm (1.75 in.).
2. Plan to install the switch with the nonport side facing the air-intake aisle.
3. Ensure that dedicated electrical branch circuits with the following
4. Plan for cable management before installing the chassis.
5. For configuration of the switch:
Planning for cable management
Attention: The minimum bend radius for a 50 micron cable is 2 in. under full
tensile load and 1.2 in. with no tensile load.
Cables can be organized and managed in a variety of ways: for example, using
cable channels on the sides of the cabinet or patch panels to minimize cable
management. Following is a list of recommendations:

SAN32B-E4 Installation, Service, and User Guide
Attention: Read the "Safety notices and labels" on page xiii before
attempting any installation, maintenance, or service procedures.
Ensure that:
v A minimum of 90.1 cubic meters per hour (53 cubic feet per minute) of
airflow is available to the air intake vents on the nonport side of the switch.
v The air intake and exhaust vents have a minimum of 2 inches of airspace.
v The air temperature on the air intake side is less than 40° C (104° F) during
operation.
characteristics are available:
v The primary outlet is correctly wired, protected by a circuit breaker, and
grounded in accordance with local electrical codes.
v The supply circuit, line fusing, and wire size are adequate, as specified by
the electrical rating on the switch nameplate.
v The power supply standards are met. See "Power specifications" on page 52.
Attention: To maximize fault tolerance, connect each power cord to a
separate power source.
Cables can be managed in a variety of ways, such as by routing cables below
the chassis, to either side of the chassis, through cable channels on the sides of
the cabinet, or by using patch panels.
v Plan for two IP addresses, and corresponding subnet masks and gateway
addresses. One IP address for the virtual IP address on the cluster
interconnect; and another IP address for the management port.
v Ensure that the following are available:
– Workstation with an installed terminal emulator, such as HyperTerminal
– Serial cable (provided)
– Three Ethernet cables
– Access to an FTP server for backing up the switch configuration or
collecting supportsave output data (optional)
– Brocade USB drive for collecting supportsave output data (optional)
– SFPs and compatible cables
