Maintaining the Brocade VA-40FC
3
Field Replaceable Units (FRUs)
The power supplies have the fans inside and can be replaced onsite without the use of special
tools. The power supply/fan assembly units are keyed to ensure correct orientation during
installation. Replacement instructions are provided with all replacement units ordered.
Power supply/fan assembly FRU replacement
The Brocade VA-40FC fans are fixed inside the integrated power supply/fan FRU to provide
necessary airflow to cool the whole system. There is one fan located in the rear section of each
FRU. The system software sets fan speed and measures their speeds through the tachometer
interface.
The two power supply/fan assembly FRU units are hot-swappable if replaced one at a time. They
are identical and fit into either slot.
Fabric OS identifies the power supplies as follows (viewing the switch from the
port
side):
•
Power supply #1 is on the left
•
Power supply #2 is on the right
Determining power supply/fan replacement need
1. Use one of the following methods to determine whether a power supply requires replacement:
•
Check the power supply status LED next to the
I
/
O
switch. If the power supply status LED
is not on, verify that the power supply is on and seated and the power cord is connected to
a functioning power source. If the light does not turn green, the power supply needs to be
replaced.
•
In Web Tools, click the Power Status icon.
•
Type the psShow command at the command prompt to display power supply status as
shown below:
2. Use one of the following methods to determine whether a fan requires replacement:
•
Check the system status LED (see
on page 20 for location of system status LED).
If the system status LED is flashing amber and green, it could mean the fan has failed. The
green power supply/fan LED will also flash in the event of failure. Check the management
interface and the error log for details on the cause of status.
•
In Advanced Web Tools, check the Fan Status icon background color. It will be either yellow
or red if the fan has failed. When the fan is functioning correctly, the background color is
green.
