Installation guide

• Power supplies can be swapped in or out while the device is running. The remaining power supply
provides enough power for the device.
• The airflow direction of the power supply must match that of the installed fan tray. All must be either
exhaust or intake.
CAUTION
Remove the power cord from a power supply before you install it in or remove it from the
device. Otherwise, the power supply or the device could be damaged as a result. (The device
can be running while a power supply is being installed or removed, but the power supply itself
should not be connected to a power source.)
CAUTION
Ensure that the airflow direction of the power supply unit matches that of the installed fan tray.
The power supplies and fan trays are clearly labeled with either a green arrow with an "E", or
an orange arrow with an "I."
Installing an AC power supply
You need a #2 Phillips screwdriver and a flat-head screwdriver for installation.
Brocade recommends using an ESD wrist strap during installation.
