Bypass Watchdog Support

Each bypass segment is support by an independent watchdog timer. The timer basis

is set to 100ms. Watchdog timeout periods can be set between 100ms and 6553.5

seconds (about 109 minutes).

The FWA-1320 also supports a global watchdog trigger which allows multiple bypass

segments to be controlled at the same time. The global watchdog signal is connected

between the two onboard bypass segments and also to the PCIe extension connec-

tor (for future use).

ment. Usually the bypass LED is implemented as a dual colour LED combined with a

regular LAN port LED. The table below shows the status of the bypass LED, only. For

a complete description of port LEDs please refer to appendix A.3.2).
