Item Specifications
Rated input voltage 100 VAC to 240 VAC @ 50 Hz or 60 Hz
Maximum input voltage 90 VAC to 264 VAC @ 47 Hz to 63 Hz
Protection against over-current input, under-voltage
input, over-voltage output, output current limiting,
output short circuit, and over-temperature.
When you install two power modules on a
device, the two power modules support 1+1
redundancy and load sharing.
You can install or remove a power module
when the switch is operating properly.

Safety precautions
To avoid possible bodily injury and power module and device damage,
follow these safety precautions:
• When you install and remove the power module, always wear
an ESD wrist strap and make sure it makes good skin contact
and is reliably grounded.
• Before you install the power module, make sure the voltage of
the power source is as required by the power module, and the
output voltage of the power module is as required by the device.
• Do not touch any cables or terminals of the power module.
