MultiModemManager Chapter 3 - Hardware Operation
MR4800E Owner’s Manual 3.1 Introduction The operation of the MR4800E consists of observing the front panel indicators (refer to Chapter 5). If the optional MultiModemManager software is installed, operation will include running the windowsbased menu and command functions from a dedicated management console (refer to the MultiModemManager’s Owner’s Manual). 3.
Chapter 3 - Hardware Operation 3.4 SNMP Interface The MR4800E can be controlled/monitored using SNMP through the MultiModemManager or a third party SNMP manager. To receive traps from the MR4800E, the SNMP manager should login using the entry in the system table. In that entry, do a set of "login PUBLIC". When you are done monitoring the MR4800E, do a set of the same variable with "logout". This will stop traps being sent to your station. MultiModemManager does this automatically. 3.
MR4800E Owner’s Manual 3.6 Telnet Interface Telnet is an Internet standard protocol that allows the remote login between two systems connected to a TCP/IP network (such as the Internet). The MR4800E can be managed remotely by using Telnet. Telnet will give the user access to all management functions through the command line interface. There is an inactivity timer associated with the Telnet session. If there is no activity for 10 minutes, then the Telnet session will close. 3.
Chapter 3 - Hardware Operation 3.8 FTP Interface FTP (File Transfer Protocol) is an Internet standard protocol that allows the transfer of files between two systems connected to a TCP/IP network (such as the Internet). The MR4800E acts as an FTP server so that FTP clients can send/receive files from it. FTP is necessary so that you can transfer configuration files (*.cfg) to/from your system. If you plan to use MultiModemManager security you will need to transfer security files (*.db) to/from your system.
