3 About the Power over Ethernet
Midspan
PowerDsine’s family of Power over Ethernet Midspans series 90XXG
inject power over data-carrying Ethernet cabling. Employing these
devices reduces the need for AC outlets, local UPS and AC/DC adapters
near PDs
PD9006G/9012G/9024G Midspans support 6, 12, and 24 ports
respectively, in a 10/100/1000BaseTx Ethernet network, over TIA/EIA-
568 category 5/5e/6 cabling. 9000G family can provide up to 30W (or
36W in Extra Power mode) according to the new PoE standard;
IEEE802.3at. DC power is fed over the spare pairs of wires within a cable
(4/5 and 7/8) to terminal units.
RPS family can provide backup or additional power to PD-90xxG
products.
Power over Ethernet Midspan normally powers devices that are Power
over Ethernet enabled or are equipped to receive power over Ethernet.
These devices are called Powered Devices (PDs).
Features of the Power over Ethernet Midspan include:
Safe and reliable power over an existing Ethernet
infrastructure
Remote management using Web control and/or SNMPv3
Highest level of network security
Safe solution that protects network infrastructure
Standards compliant: IEEE 802.3af and 802.3at
Provides safe Power + Data over a single RJ45 cable
