8 1 - INSTALLING THE BYPASS NICS

The HP EFS WAN Accelerator is equipped with a bypass card to prevent a single point

of failure. If there is a serious problem with the HP EFS WAN Accelerator, it goes into

bypass mode and the traffic is passed through unoptimized. You can install multiple-

port bypass cards to connect to multiple routers and switches.

The HP EFS N4c WAN Accelerator 4-port NIC, HP EFS N2c WAN Accelerator 2-port

NIC, and HP EFS N2f WAN Accelerator 2-port NIC are supported by HP EFS WAN

Accelerator, version 2.1.5 (or higher) software.

NOTE: There are hardware limitations on how many cards are supported.

The HP EFS N4c WAN Accelerator 4-port NIC, HP EFS N2c WAN Accelerator 2-port

NIC, and HP EFS N2f WAN Accelerator 2-port NIC enable you to connect to multiple

routers and switches connecting your Local Area Network (LAN) and Wide Area

Network (WAN). With these bypass NICs, you can use the same data store in the HP

EFS WAN Accelerator across multiple links in your network.
