Figure A2-3 YFGW410/YFGW510-redundant configuration
Figure A2-3 shows the YFGW410/YFGW510-redundant system configuration.
The Layer 2 switch between YFGW410 and YFGW510 must support the rapid spanning tree
protocol (RSTP) to prevent network loops, and the IEEE1588v2 (precision time protocol).
For recommended Layer 2 switches, see the User's Manual of YFGW410 (IM 01W02D01-
01EN).
As shown above, field wireless networks can be built with various system configurations.
