Figure 20 VPN Router Security Accelerator card

The VPN Router Security Accelerator card is the successor to the Hardware Accelerator card. Even though Nortel discontinued the Hardware Accelerator Hifn 7811 card effective January 2006, Nortel still supports this card. The VPN Router Security Accelerator card provides increased encryption throughput and improved compression performance.

Note: The VPN Router Security Accelerator card has one green Light Emitting Diode (LED); the Hardware Accelerator card has no LEDs.

At startup, after you manually enable an accelerator card, or after the accelerator recovers from a failure, the power-on self-test (POST) verifies the integrity of the hardware. This test includes validation of the encryption, media access control (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 the Hardware Accelerator card, and instructions to configure these cards, see Nortel VPN Router Configuration — Advanced Features (NN46110-502).
