Only Redundancy Power Supply (RPS) is supported for DC power supply. In the case of RPS input, the
WX3024E can supply 720 W power to the PoE devices connected to it. The maximum output power for
each port is 30 W.
NOTE:
•
Use only H3C-recommended RPS 1600 for DC power supply. RPS 1600 and RPS cables are optional.
Order them by yourself.
• The DC power cords should be shorter than 3 meters (9.84 ft.) to minimize voltage attenuation.
• For how to install an RPS, see the chapter “Installing the switch (page 17 ).”

PoE power supply
The WX3024E supports Power over Ethernet (PoE) to provide –48 VDC supply to attached powered
devices (PDs), such as IP phones, WLAN APs, and security and Bluetooth APs, through twisted pair
cables.
CAUTION:
Only the H3C-recommended external PoE power supply (RPS) can be used as the DC input, rather than
the –48 VDC power supply of the equipment room, which may cause device damage.
• As a power sourcing equipment (PSE), the WX3024E supports the IEEE 802.3at standard while
being compatible with some PoE powered devices that do not comply with the 802.3at standard.
• The WX3024E provides power supply through fixed electrical Ethernet ports, with the maximum
power transmission distance of 100 meters (328.08 ft).
• Each Ethernet port of the WX3024E provides a maximum of 30 W output power to the attached
PoE powered devices. In the case of AC input, the maximum output power with full load of the
WX3024E is 370 W; in the case of RPS input, the maximum output power of the WX3024E is 30
W × 24 ports = 720 W (The RPS output power should be at least 740 W).
Fans
The WX3024E is equipped with five fans: two for heat dissipation of the main board and three on the
power supply for heat dissipation of the power supply system.
