Field replaceable units (FRUs)
The Brocade VA-40FC has two integrated power supply/fan unit field replaceable units (FRUs).
These power supply/fan assembly units are hot-swappable and redundant, and are capable of
functioning universally without voltage jumpers or switches. The FRU units are identical and
interchangeable.
The front panel has a status LED that provides the status of the entire switch, including the two
power supply/fan FRUs.
The airflow for the Brocade VA-40FC is configured at the factory to have either the:
• Airflow exhaust at the non-port end.
• Airflow intake at the non-port end.
The fans inside a power supply/fan FRU either intake air or exhaust air from the chassis, depending
on the model. Using the same P/N for all power supply/fan FRUs ensures identical airflow for all
the FRUs on the chassis. When a replacement power supply/fan FRU is required, the same part
number must be used and the FRU must match what was originally shipped in the Brocade
VA-40FC.
The power supply/fan unit handle color is also an indicator of the of model type. The handles for
the installed FRUs should be the same color.
Additionally, you can use external labels as a guide. Some power supply/fan units are labeled with
an airflow symbol on the faceplate to indicate whether the unit intakes or exhausts air. However,
not all power supply/fan units have an airflow symbol label.

Ports on Demand license
The Brocade VA-40FC has 40 ports. By default, ports 0-24 are enabled. To enable additional ports,
you must install Ports On Demand (POD) licenses.
To install a POD license, you can either use the supplied license key or generate a license key.
Typically the switch is shipped with a paper pack that specifies the transaction key to use with the
Software License Keys link. Use this transaction key on the Brocade Web site at
www.brocade.com/licensekeys and follow the instructions to generate the key. You can also use
this site to generate other license keys for your switch.
After you have installed the license keys, you must enable the ports. You can do so without
disrupting switch operation by using the portEnable command on each port individually.
Alternatively, you can disable and re-enable the switch to activate all ports simultaneously.
