The VPN Router Security Accelerator card is the successor to the Hardware
Accelerator card. The Hardware Accelerator Hifn 7811 card has been
discontinued effective January 2006 although Nortel still supports this card.
However, the VPN Router 2750 does not support the Hardware Accelerator card.
Along with providing support for AES, the VPN Router Security Accelerator card
provides increased encryption throughput and improved compression
performance.
Note: The VPN Router Security Accelerator card has one green LED.
At startup, when you manually enable an accelerator card, or when the accelerator
recovers from a failure, the power-on self-test (POST) verifies the integrity of the
hardware. This test includes validation of the accelerator's encryption, MAC, and
compression algorithms against their software counterparts. In the event POST
fails, the accelerator card is set offline.
For more information about the VPN Router Security Accelerator card and
instructions for configuring this card, see the guide Nortel VPN Router
Configuration — Advanced Features (NN46110-502).
