The switch has two Power Supply Units (PSU) and four fan modules. The fan modules can be built in
as back-to-front or front-to-back depending on customer requirements.
The AC power connector is a standard three-pronged connector. The switch automatically adjusts its
power setting to any supply voltage in the range from 100~240 VAC at 50~60 Hz.
When the PSU is connected to the power source, the PSU LED lights green.
