The Advantech FWA series consists of off-the-shelf x86 high-performance network appliances that have been designed and tested to run an extensive range of enterprise networking applications. To ensure maximum system uptime in business critical operations, Advantech provides higher levels of availability through a number of key methods, namely redundant hardware options, including power supplies and storage, LAN bypass, ECC memory and software availability capabilities.
Advanced Lan Bypass
Safeguard the continuity of your business critical services by eliminating single points of failure with LAN bypass. Advantech’s advanced LAN Bypass feature guarantees uptime by preserving network connectivity and maintaining communications in case of power outage or appliance malfunction. When Bypass Mode is active, multiple interface pairs can be bridged on power failure and will resume normal functionality when power is restored.
Bypass is of particular importance for applications such as WAN optimization, SPAM filtering and many bump-in-the-wire applications. The loss of email filtering functions for example should not impact email delivery while services are waiting to be restored.
On the other hand physical disconnect is essential for network security applications such as firewall, IDS/IPS etc in order to ensure physical isolation. Bypassing a firewall is obviously not an option.
Physical disconnect also allows isolation of ports during power-on and boot, only enabling connectivity when applications are securely up and running.
Note: A network segment consists of two adjacent ports. A quad-port NIC has two segments, for example.
