Installation ManualH3C S7502 Ethernet Switch Chapter 1 Product Overview1-30Figure 1-30 Appearance of an external PoE power supplyNote:z The S7502 supports a PoE power supply with up to 1500 W power output. A singlePoE module can provide 1250 W power output, and two can provide up to 2400 Wpower output in the case that PSE2500-A3 supplies 100 VAC to 140 VAC inputvoltage. Three PoE modules are required to provide output power of 2400 W ifpower supply redundancy is desired. With 200 VAC to 240VAC input voltage, asingle PoE module can provide 2500 W power output. Two PoE modules arerequired to provide 2500 W power output if power supply redundancy is desired.z There are S7502 PoE chassis and non-PoE chassis. If the PoE function is required,select an S7502 PoE chassis.1.11.6 Fan TrayThe fan tray is on the right side of an S7502 chassis, and directly connected to thebackplane through a connector. The fan fault signals are summarized and transmittedfrom the backplane to the SRPU for further processing. The fan tray is hot-swappable.Figure 1-31 Fan tray on an S7502
