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 windows-

based menu and command functions from a dedicated management console (refer to the

MultiModemManager’s Owner’s Manual).

3.2 Security

The MR4800E has a security system to prevent unauthorized system modification by Telnet, Web

browser, or FTP users who access the system via the TCP/IP network or the diagnostic serial port on

the back of the CC4800 rack. SNMP and MultiModemManager software security is done by the

selection of SNMP read and write community strings.

There are three levels of security, guest, operator, and supervisor. There are also default userids and

passwords for each level (see table below).

3.3 File System

The MR4800E utilizes a file system for storing configuration, security, and event information. There

are two drives on the system: A and B. The A drive is used for non-volatile information such as

configuration and security database files, and is about 1 MB in size. The B drive is for volatile

information such as event files and is about 6.5 MB in size. Each drive has an MMM directory on it.

A:\MMM stores all the configuration information for the system. B:\MMM\MR.LOG contains all of the

event files for the system. The file system can be accessed either through the command line

interface or by using FTP.

3.3.1 Event Files

One file for each hour is started in the format of: MMDDHHYY.HR, where MM is the month, DD is the

day, HH is the hour, and YY is the last two digits of the year. When the drive fills up, the oldest .HR

file is deleted. The number of events your MR4800E will hold depends on the number of calls you

receive in a day. Event files can be FTPed off the MR4800E and analyzed using the Stastical

Analyzer which is part of the MultiModemManager software.
