109SAN Switch 2/8V, 2/16V, 2/16N and 4/32 installation guide

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 toward the port side of the

switch.

Table 33 lists the power supply specifications.
