ESM/VCPM MODULE
ANDE Module
Introduction 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.
Interface Attributes The following table describes the interface attributes of the FIC-HNDE.
Interface LEDs 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.
Installing/Removing
ANDE Card
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.
Removing ANDE card
Follow these steps to remove the ANDE card:

Table 172 Description of the LEDs on the panel
LED Description
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.
Note:
x means the number of the slot the ESM LED is in.
