Power Requirements
DC input voltage
• Maximum operating range: 9.6 to 60 VDC
• Nominal: 12, 24, or 48 VDC
Note
• The DC-input power supply is an SELV circuit, and it can
only be connected to another SELV circuit.
• Input voltage for power supplies:
–
To power the switch, PWR-IE50W-AC-IEC and
PWR-IE50W-AC provide 24 VDC at 2.1 A.
–
To support PoE, power supplies PWR-IE65W-PC-AC
and PWR-IE65W-PC-DC provide 54 VDC at 1.2 A.
• The IE 2000 switch models with PoE capability are
equipped with an additional DC input terminal block that
allows the connection of a second power supply or a second
input from site source DC power to operate the PoE ports.
The PoE terminal block accepts 48 VDC or 54 VDC at up to
2.5 A, depending on the amount of power that is provided to
the connected devices.
–
PoE mode: 48 VDC (nominal)/44-57 VDC (absolute
range)
–
PoE+ mode: 54 VDC (nominal)/50-57 VDC (absolute
range)
Maximum DC input current
• 1 A @ 48 VDC
• 2 A @ 24 VDC
• Switch models with PoE capability: 48 VDC or 54 VDC at
2.5 A
