Contivity Security Accelerator (Csa) And Hardware Accelerator Cards - Nortel Contivity 5000 Installing

This section provides information about the option cards, including the connector
and the cable pinouts for each supported network interface card.
Contivity Security Accelerator (CSA) and Hardware
Accelerator cards
Nortel Networks supports two option cards that perform bulk encryption and
compression algorithms for IPsec tunnel traffic:
• Contivity Security Accelerator (CSA) card
The CSA card uses a single Hifn
and has 64 MB of onboard RAM. It supports AES-128 cryptography with
SHA-1 authentication and triple DES cryptography with either MD5 or
SHA-1 authentication.
• Hardware Accelerator card
The Hardware Accelerator card uses a single Hifn 7811 chip for encryption
and compression. It performs triple DES and DES cryptography, LZS
compression, and MD5 or SHA-1 authentication.
The CSA card is the successor to the Hardware Accelerator card. Along with
providing support for AES, the CSA card provides increased encryption
throughput and improved compression performance.
Note: The CSA card has one green LED; the Hardware Accelerator card
has no LEDs.
At startup, whenever an accelerator card is manually enabled, or whenever 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 Contivity Security Accelerator card and the
Hardware Accelerator card and instructions for configuring these cards, see the
guide Configuring Advanced Features for the Contivity Secure IP Services
Gateway.
