Replacing Other Components
Replacing a Nokia Encryption Accelerator Card
The IP561 comes with the Nokia encryption accelerator card preinstalled as part of its base
bundle to further enhance VPN performance. The accelerator card provides high-speed
cryptographic processing that enhances VPN performance.
The IP561 appliance uses a PMC format accelerator card. The accelerator card has no external
connections and requires no cables. The accelerator card software package is part of IPSO-VN,
so the appliance automatically detects and configures the card.
Use Nokia Network Voyager to configure your software applications to make use of the
available hardware accelerator. For information about how to configure software applications,
see
"Configuring Software to Use Hardware Acceleration"
This section describes how to replace a previously installed accelerator card.
Before You Begin
To replace the accelerator card, you need:
Physical access to the appliance
The Nokia encryption accelerator card and installation kit
Phillips-head screwdriver
Four screws (included in kit)
Grounding wrist strap (included in kit)
Caution
To help guard against electrostatic discharge damage, make sure you are properly
grounded by using a grounding wrist strap and following the instructions provided with
the wrist strap before you handle the components or open the appliance.
Note
You do not need to manually disconnect power for this procedure. If the power supply switch
at the rear of the appliance is difficult to reach, you can safely disconnect power when you
remove the chassis tray assembly from the front of the appliance. Any servicing of the
appliance should be completed with the chassis tray assembly fully removed from the
appliance.
To replace the accelerator card
1. Use Nokia Network Voyager or the command-line interface (CLI) to perform an orderly
shutdown of the IP561.
For information about how to access Network Voyager and the related reference materials,

2. Turn off the power to the IP561 appliance.
