Power specifications
The power supplies are universal and capable of functioning worldwide without
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 has a built-in fan for cooling, pushing air towards
the port side of the switch. Table 16 lists the power supply specifications for the
switch.
Data transmission ranges
Table 17 provides the data transmission ranges for different cable types and port
speeds.
Note: The full range of 1, 2, 4, and 8 Gbps can only be achieved by a combination
