• 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.
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.

10/100BASE Ethernet interface card

The 10/100BASE Ethernet interface card has a single RJ-45 connector that
provides the signals needed to interface to 10BASE-T and 100BASE-TX Ethernet
equipment.

For information about the cables that you can connect to this interface and the
cable pinouts, see
317086-B Rev 00
Note: The CSA card has one green LED; the Hardware Accelerator card
has no LEDs.
