Power supply specifications
The power supplies are universal and capable of functioning worldwide without using
voltage jumpers or switches. They meet IEC 61000-4-5 surge voltage requirements
and are autoranging in terms of accommodating input voltages and line frequencies.
Each power supply integrates its own built-in fan for cooling, pushing the air forward
toward the port side of the switch.
Table 31 lists the power supply specifications.
