Oracle Talari E1000 | Hardware Guide
Troubleshooting Inline Mode (Fail-to-Wire)
The E100 APNA is equipped with a capability known as Inline mode with the interfaces
in Fail-to-Wire. This capability is designed to prevent a single point of failure. If there is
a serious problem with the E100 APNA, the bypass pair goes into bypass mode and
forwards traffic through as though the appliance were a wire.
Interfaces may be configured as either Fail-to-Wire or Fail-to-Block. If a bypass pair is
configured for Fail-to-Block, bypass mode will never be activated, even if power is lost.
If configured, bypass mode is used when the APNA is not powered on or when
the Talari Service is disabled.
Please also see the section above, “Important Note About Cabling and Bypass Mode”.
