2.6 Bypass Fault Device in Daisy-Chain or Ring Topology
Auto-bypass function has been applied on G1 and G2 for rolling stock applications. In
the metro or ring network, the topology may be segmented into several fractions by one
failure power node. As a result, some of the segments or nodes cannot communicate with
each other. The port Bypass function can connect remote network fragments by linking
uplink and downlink ports together when the Switch is powered down. With this feature,
the Switch can ensure that train communication always works appropriately.
2.7 M12 USB Auto-Configuration
The JetNet 6910G has enabled USB memory access function for the configuration restore/backup. The
function brings benefits to the field engineers maintaining/upgrading the system without special tools or
configuration knowledges. The system kernel will automatically restore the desired configuration if the
configuration files existing in the M12/USB memory
stick with specified file name. It also makes the
on-field Ethernet Switch replacement/ exchange process easy and friendly.
