Installing AC Power Supplies | 33The following tables provide a mapping between the supported PoE/PoE+ ports and the PSUs for asystem configuration that contains 2 RPMs, variable speed fan tray, and 8 PoE+ Line cards.Power Over Ethernet Plus (PoE+)The C-Series can transmit power to Ethernet devices over the signal pairs of an Shielded Twisted Pair(UTP) cable. A maximum of 30.0 Watts (at 54 Volts) can be transmitted over a link. The chassis transmitspower to connected IEEE 802.3at-compliant devices via ports that are enabled with PoE+. The higherpower of PoE+ (30W/port) is available only with Power Supply 1600W-AC and the PoE+ line card.Table 7-2.
