	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.
	Installing ANDE card
	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.
c	CAUTION: You should connect a cable to the port with the correct mark.
	Misplugging is prone to impair the interface card and even damage the router.

SNDE Module

Introduction 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.

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

Table 173 Interface attributes of the SNDE module

Attribute	Description
Protocol supported	IPSec
IPSec concurrent tunnels	100 (implemented through software)
Hardware algorithm	key algorithm (DES, 3DES, AES, QC5,
	Blowfish, Cast-128 and SkipJack)
	Authentication algorithm
	(HMAC-MD5-96, HMAC-SHA-1-96)

Interface LEDs 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.
