Microsens MS400089 - Manual (Page 3)

1. Overview
10/100/1000Base-T to 1000Based-SX/LX LC IEEE802.3z /ab
GbE media converter, which allows two types of network
segments to be connected easily and inexpensively. Complied
with IEEE802.3af Power Over Ethernet standard, this AC
powered PoE media converter is a Power Sourcing Equipment
(PSE) which combines data received over a TP link with –48VDC
power, providing power to IEEE802.3af powered device (PD) over
the existing CAT5 UTP cable. The converter includes a PD
signature sensing and power monitoring features. Other features
include over-current protection, under-current detection and fault
protection input. The LFP (Link Fault Pass-through) allows the
media converter to monitor both the fiber and copper RX ports for
loss of signal. In case of a loss of RX signal on one media port,
the converter will automatically disable the TX signal to the other
media port, thus passing through the link fault. FEF (Far End
Fault) enables the converter to stop sending link pulse to the link
partner once a loss of the fiber RX signal is encountered. Then
the link partner will synchronously stop sending data. FEF
prevents loss of valuable data transmitted over invalid link.
2. Checklist
