The following tables provide a mapping between the supported PoE/PoE+ ports and the PSUs for a
system 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 transmits
power to connected IEEE 802.3at-compliant devices via ports that are enabled with PoE+. The higher
power of PoE+ (30W/port) is available only with Power Supply 1600W-AC and the PoE+ line card.
