Installing an Encryption Accelerator Card
This section describes how to replace the Nokia Encryption Accelerator Card.
The card is included with the Nokia 500i gateways and installed before the
gateway is delivered to you. These instructions apply only if you are replacing
the card.
The Nokia Encryption Accelerator Card provides high-speed cryptographic
processing that enhances the performance of VPN tunnels. By taking over
cryptographic processing, the card allows the gateway CPU to perform other
tasks.
The Nokia Encryption Accelerator Card is in a PMC format for the Nokia
500i. This card has no external cable connection ports and requires no cables.
The following security algorithms are supported:
!
MD5 and SHA-1 authentication
!
DES and 3DES encryption
!
128-bit, 192-bit, and 256-bit AES encryption
To install the accelerator card
1.
Turn off the power switch on the rear of the gateway and unplug the
power cord.
Note
If you cannot access the power switch, you can still perform this
procedure. When the slide tray assembly is removed from the chassis
assembly, power to a Nokia 500i is automatically disconnected.
