Equipped with external power supply and PoE-capablecards, S9500 series can provide 48 VDC power for remote powered devices (PDs,such as IP phones, WLAN APs, and Network cameras) through twisted pairs.z The S9500 series support LEGACY Power Supply standard. While they can alsosupply power to PDs noncompliant with the standard.z The power supply of the S9500 series is administered by the SRP card; each PoEcard on the switch can be viewed as a power sourcing equipment (PSE), whichadministers the power supplying of all the ports on it independently.z The S9500 series can transmit data and supply power in the mean time throughthe signal lines (1, 3, 2, and 6) of the category-3/5 twisted pairs. Using converters,they can also supply power to the PDs that can be powered only through sparelines (4, 5, 7, and 8).z The S9500 series supply power through the Ethernet electrical ports on theservice cards. Each service card can supply power to up to 48 remote devices atthe maximum distance of 100 m (328 feet).z The maximum power that can be supplied by each Ethernet port to its PD is 15.4W.z When supplying power to remote devices, the maximum total power that can beprovided by the S9500 series is 4500 W (220 V)/2250 W (110V). The switchdetermines whether or not to supply power to the next remote PD it discovereddepending on the total power it currently supply.
