Installing the Contivity 1700
Hardware option cards
The Contivity 1700 provides two PCI slots that support a combination of the
following option cards:
•
Hardware Accelerator card
•
10/100BASE Ethernet interface card
•
56/64K CSU/DSU WAN interface card
•
ADSL WAN interface card
•
ISDN BRI interface card
•
T1 CSU/DSU WAN interface card (full-height card)
•
T1/E1 CSU/DSU WAN interface card (half-height card)
•
Quad T1/E1 CSU/DSU WAN interface card
•
V.90 modem interface card
•
Single V.35/X.21 WAN interface card
•
Dual V.35 WAN interface card
•
HSSI WAN interface card
This section provides information about the option cards, including the connector
and the cable pinouts for each supported network interface card.
Hardware Accelerator card
The Hardware Accelerator card performs bulk encryption and compression
algorithms for IPsec tunnel traffic. 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.
At startup, whenever a Hardware Accelerator card is manually enabled, or
whenever the card recovers from a failure, the power-on self-test (POST) verifies
the integrity of the hardware. This test includes validation of the accelerator card’s
encryption, MAC, and compression algorithms against their software
counterparts. In the event POST fails, the Hardware Accelerator card is set offline.
For more information about the Hardware Accelerator card and instructions for
configuring it, see the guide
