Chapter 7. Power Supply Assemblies

The power supply assembly units in the SAN128B-7 chassis can be removed and replaced without special

nonport-side of the device.

• AC power supply with nonport-side air intake. This unit moves the air from the nonport-side to the

port-side of the device.

Note: The two power supply assemblies concurrently installed in the chassis must be of the same

power type, model (airflow direction), and part number. If the airflow directions are different, an error is

generated on the console.

Note: The power supply assembly units are hot-swappable if they are replaced one at a time. They are

identical and fit into either slot.

Note: The device can operate all the ports with one power supply assembly unit if you do not require

redundancy.

Each power supply unit has one internal fan.

DANGER: Make sure that the power source circuits are properly grounded,

then use the power cord supplied with the device to connect it to the power

source.
