Silicom Bypass server adapters include an on board Controller that can Bypass the Ethernet ports on host system failure like

Power Off, System hangs or software application hangs. The software programmable Watch Dog Timer (WDT) Controller detects a

host system fails and it will Bypass automatically the Ethernet ports after programmable time out interval. The WDT Controller can

be software programmable enabled or disabled.
