I NTRODUCTION
The SRPM12 injects power over data-carrying Ethernet cable. The Midspan supports 12 ports in a
10/100BASE-TX network, over TIA/EIA-568 Category 5/5e/6 cabling. Power for data terminal units is
carried over the unused pairs of cabling (4/5 and 7/8).
The Power over Ethernet Midspan powers devices that are Power over Ethernet capable. These devices
are called Powered Devices (PD). Devices that are not designed to receive power over Ethernet will
require an external power splitter adapter in order to be powered by the SRPM12.
Features
The SRPM12 features include:
‹ IEEE 802.3af Power over Ethernet compliant.
‹ Provides LED indicator for System and PoE status.
‹ Eliminates the need for AC outlets, local UPS and AC/DC adapters
‹ Web based Management for System and PoE power management.
‹ Independent overload and short-circuit protection per channel
‹ Standard 19-inch rack mountable.
Ports
Data ports (upper row of ports): Twelve (12) 10/100Mbps Fast Ethernet data input ports. These ports
are designed to carry only data over the standard 2-wire pairs (pins 1/2 and 3/6).
PoE ports (lower row of ports): Twelve (12) 10/100Mbps Fast Ethernet with DC power output ports.
These ports are designed to carry data over the standard 2-wire pairs (pins 1/2 and 3/6) and DC power
over the spare pairs (pins 4/5 and 7/8).
Management port: One (1) 10/100Mbps Ethernet/Fast Ethernet port for out-of-band management.
