port on the rear panel. Ethernet built-in layer-2 switch function. Supporting VLAN
setting based on
802.1Q or 802.1ad Q in Q, and VLAN priority settings. The 6 GE ports could
realize Ethernet switching function. Anyone of them can be used for uplink or local data
transport, or anyone of GE electrical port could be used for NMS port.
GE electrical port adopts RJ45 socket, RJ45 Ethernet socket is defined as Table 2.4-4.
Ethernet optical port uses LC connector, depending on different transmission distance, different
SFP optical module could be selected. The port labeled
（
Æ
is for optical signal output,
（
Å
for
