Note: The PD device should accept power from either 1,2,3,6 (data pairs) or 4,5,7,8
(spare pairs); for the detail information, please refer to IEEE 802.3at / IEEE 802.3af Power
over Ethernet standard.
Gigabit Ethernet /SFP combo port
The PMI‐110‐F2G provides 2 Gigabit RJ‐45/ SFP combo ports that with different link
speed – 10Mbps, 100Mbps, 1000Mbps, and compliant with the standards of IEEE 802.3
10Base‐T, IEEE 82.3u 100Base‐TX, IEEE 8023.u 100Base‐FX, IEEE 802.3ab 1000Base‐T, and
IEEE 802.3z Gigabit fiber.
The combo ports support SFP transceiver plug‐in high priority function; thus, don’t
connect Ethernet RJ‐45 and insert SFP transceiver at the same time; it will cause the port
being activated in wrong status.
The SFP ports also provide Digital Diagnostic Monitoring function, it can assist user to
monitor the quality of optical signal, and diagnose the transmission of fiber.
This function
is only available for Westermo recomended DDM SFP transceiver, and does not support
third party transceiver that may not fully comply with MSA SFP transceiver standard.
By the DDM function, user can get real information including the strength of received
optical signal, launched optical signal and current operating temperature of SFP
transceiver, and the specification of transceiver.
The following diagram shows the information captured from WEB user interface.
Range: the specification of Westermo defined.
Current: actual value read from SFP transceiver.
Tx Power (dBm): optical strength of received.
Rx Power (dBm): optical strength of launched.
Note: The Ethernet Switch has to use UL recognized fiber transceiver with Class 1 Laser/LED Diode.
Note: It is recommended to not plug‐in SFP fiber transceiver and link up RJ‐45 port at the same time, it
might cause the connection does not working properly.
