Overview
Power over Ethernet (PoE) is an effective method of supplying 48 VDC power to certain types of
powered devices (PDs) through Category 5 or Category 3 twisted pair Ethernet cables. PDs
include wireless access points, IP telephones, laptop computers, web cameras, and other
devices. With PoE, a single Ethernet cable supplies power and the data connection, reducing
costs associated with separate power cabling and supply.
The system supports hitless failover for PoE in a system with two Management Switch Fabric
Modules (MSMs). Hitless failover means that if the primary MSM fails over to the backup MSM,
all port currently powered will maintain power after the failover and all the power configurations
remain active.
NETGEAR Networks PoE Devices
The XCM8848T module (with daughter card) for the NETGEAR 8800 series switch supports
PoE.
