Connecting the Power Inputs
NOTE
The required power module depends on the choice of LM-7000H
module. Refer to the following power/module combination
requirements.
•
LM-7000H non-PoE modules:
Any power module
•
LM-7000H PoE modules:
PWR-HV-P48-A, PWR-LV-P48-A only
The MDS-G4000-4XGS/MDS-G4000-L3-4XGS Series supports 4 types of
power supply:
• PWR-HV-P48-A: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300
VDC), one 48 VDC PoE power input for PoE+ ports.
• PWR-LV-P48-A: one 24/48 VDC (18 to 72 VDC), one 48 VDC PoE
power input for PoE+ ports.
• PWR-HV-NP: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300
VDC) power input.
• PWR-LV-NP: one 24/48 VDC (18 to 72 VDC) power input.
For the PWR-HV-P48-A, the 110/220 VAC/VDC power supplies provide
power to the switch. Separate 48 VDC power supplies are required to
provide power to all PoE+ ports (50 to 57 VDC is recommended for
IEEE 802.3at devices. The maximum PoE output from an external
power supply is 720 W when the operating temperature is under 60°C;
360 W when the operating temperature is under 75°C.)
For the PWR-LV-P48-A models, the 24/48 VDC power supplies provide
power to the switch. Separate 48 VDC power supplies are required to
provide power to all PoE+ ports (50 to 57 VDC is recommended for
IEEE 802.3at devices. The maximum PoE output from an external
power supply is 720 W when the operating temperature is under 60°C;
360 W when the operating temperature is under 75°C.)
For the PWR-HV-NP, the 110/220 VAC/VDC power supplies provide
power to the switch. For the PWR-LV-NP, the 24/48 VDC power supplies
provide power to the switch.
