Power Over Ethernet Plus (PoE+)
The C-Series can transmit power to Ethernet devices over the signal pairs of an Unshielded Twisted Pair
(UTP) cable. A maximum of 30.0 Watts (at 53 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+. A minimum of
three Power Supply 1600W-AC power supplies are required to enable PoE+. The higher power of PoE+
(30W/port) is available only with Power Supply 1600W-AC and the PoE+ line card.
