LED Description
Note:
x means the number of the slot the ESM LED is in.
Installing/removing an ANDE module
ANDE 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 an ANDE module
Follow these steps to remove the ANDE module:
Step1 Remove the fastening screws on the ANDE module.
Step2 Remove the ANDE module from the mother board. Do not overexert when removing the ANDE
module because the connector of the daughter board is still on the mother board.
Step3 If no ANDE 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 an ANDE module
Follow these steps to install ANDE module:
Step1 Confirm the correct position of the ANDE module on the
Step2 For an MSCA/MSCB module, fasten the four metal standoffs which fasten and support ANDE module.
For other mother boards, fasten the four metal standoffs on the mother board. Step 3: Install the ANDE
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.
You should connect a cable to the port with the correct mark. Misplugging is prone to impair the
interface module and even damage the router.
SNDE
Introduction
Standard network data encryption engine (SNDE) supports IPsec and hardware expedited IP data
packet encryption, thus providing encryption with high performance and reliability.
Installed with an SNDE module, the main board of your router can implement VPN with encryption
provided by the SNDE module in addition to IP packet forwarding.
