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.

Green: SNDE module is in the slot and is operating normally.Yellow: SNDE module is in
the slot but cannot be accessed by the router.
Note:
x means the number of the slot the ESM LED is in.
Installing/removing SNDE module
SNDE module should be installed on the main board of an MSR 20/30 router or the ESM slot on the
MSCA/MSCB module of an MSR 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.
Removing SNDE module
Follow these steps to remove the SNDE module:
Step1 Remove the fastening screws on the SNDE module.
Step2 Remove the SNDE module from the .mother board. Do not overexert when removing the SNDE
module because the connector of the daughter board is still on the mother board.
Step3 If no SNDE module is to be installed, for an MSCA/MSCB module, 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 SNDE module
Follow these steps to install SNDE module:
Step1 Confirm the correct position of the SNDE module on the
Step2 For an MSC module, fasten the four metal standoffs which fasten and support SNDE module. For
other mother boards, fasten the four metal standoffs on the mother board. Step 3: Install the SNDE
module 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.
