8LED DescriptionVCPM• OFF means no VCPM is in the slot.• Steady green means a VCPM is in the slot and operates normally.• Steady yellow means a VCPM is in the slot but does not operate normally.VPM0 to 1• OFF means no VPM is in the VPMx slot.• Steady green means a VPM is in the VPMx slot and operates normally.• Steady yellow means a VPM is in the VPMx slot but does not operate normally.Generic ModulesThe MSR 20 is available with generic modules such as SIC interface card and ESM. For detailedinformation about interface cards, refer to MSR Series Routers Interface Module Manual.For the types of interface modules that each model of the MSR 20 routers can accommodate, refer toAppendix A Interface Card and Interface Module Purchase Guide in the MSR Series Routers InterfaceModule Manual.SIC and DSIC Interface CardsMSR series routers adopt modular design and support a wide range of optional SIC/DSIC interfacecards, providing various interfaces, such as synchronous/asynchronous serial interface, Ethernetinterface, E1/T1, ISDN BRI/PRI, ADSL, audio interface, and Layer 2 switching interface, and so on.NOTE:• For an MSR 20-40 router, 4FSW/1FEA/1GEC/1ADSL/1ADSL-I can only be installed in Slot 2 or Slot4.• Currently, MSR 20 routers do not support PoE and regard SIC-4FSW-POE and DSIC-9FSW-POE (ifused) as only ordinary Layer 2 switching modules.ESM Module• High-performance network data encryption ESM module (ESM-ANDE)• Standard network data encryption ESM module (ESM-SNDE)ESM module supports IPSec and by using hardware encryption expedites IP packet encryption. The useof hardware encryption/decryption and hashing operation allows the router to encrypt packets with highperformance and reliability.The encryption card is optional. On a router installed with an encryption card, the main control boardfunctions to route IP packets and implement encryption-enabled VPN, while the encryption card functionsto encrypt packets.Table 8 Encryption card attributesAttribute DescriptionProtocol IPsec
