About the PD-Switch
The PD-Switch is an unmanaged Ethernet powered device (IEEE 802.3af) that allows
the port density and service area of Ethernet networks to increase. As a powered
Layer 2 device, this switch receives power over the Ethernet cable instead of using a
separate power outlet, providing Ethernet service to locations without being
constrained by the availability of power outlets. The store and forward switch
function allows the extension of Ethernet service to locations a total of 200 meters
from the Ethernet source. All RJ-45 Ports auto negotiate 10/100BaseT, full/half
duplex, and automatically configure for MDI or MDIX operation. The optional Fiber
Port is fixed at 100 Mbps full duplex.
The PD-Switch provides a variety of port configurations:
• One IEEE 802.3af PoE compatible RJ-45 port (Port 1 “PD”)
• One high-priority RJ-45 port (Port 2)
• And one of the following three configurations:
Configuration 1: Three additional RJ-45 data ports (all copper version)
Configuration 2: Two additional RJ-45 data ports and one SFP data port
Configuration 3: One additional RJ-45 data port and one Fiber-Optic data port (SFP).
Port 2 is dedicated for high priority applications. All other RJ-45 ports provide fixed
DiffServ/ToS-PRI prioritization, giving higher priority to all traffic with a VLAN TAG
with PRI>4. All RJ-45 ports incorporate the Auto Cross and Auto Negotiation
features. The Fiber-Optic configuration also includes the Far End Fault feature that
provides notification of far-end link loss on the fiber port.
