Step 1: Remove the fastening screws on the ANDE card.

Step 2: Remove the ANDE card from the mother board. Do not overexert when 
removing the ANDE card because the connector of the daughter board is still on 
the mother board.

Step 3: If no ANDE card is to be installed, for an MSCA card, remove the four 
screws fastening the metal standoff on the daughter board and take the four 
metal standoffs. For other mother boards, remove the four metal standoffs.

Follow these steps to install ANDE card:

Step 1: Confirm the correct position of the ANDE card on the

Step 2: For MSCA card, fasten the four metal standoffs which fasten and support 
ANDE card. For other mother boards, fasten the four metal standoffs on the 
mother board. Step 3: Install the ANDE card on the mother board and fasten it 
with four screws. During installation, align the two connectors under the daughter 
board to the connectors on the main board to avoid damage to the connectors.

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

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

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

There is no LED on the SNDE 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 SNDE panel.
