ANDE (advanced network data encryption card) supports IPSec and hardware 
expedited IP data packet encryption, thus providing encryption with high 
performance and reliability.

■

Installed with an ANDE card, the main board of your router can implement VPN 
with encryption provided by the ANDE card in addition to IP packet forwarding.

The following table describes the interface attributes of the FIC-HNDE.

There is no LED on the ANDE module. Display of the status of the module is 
implemented through the ESM interface LED on the main board of the router.

The following table describes the LEDs on the panel.

ANDE card should be installed on the main board and the ESM slot on the MSCA 
card of MSR 20/30/50 router. The board that provides ESM slots is referred to 
hereafter as mother board. Suppose the mother board is uninstalled and put on 
the workbench.

Follow these steps to remove the ANDE card:

ESMx 

Green: ANDE card is in the slot and is operating normally. 

Yellow: ANDE card is in the slot but cannot be accessed by the router. 

x means the number of the slot the ESM LED is in.
