Chapter 2 - Hardware Installation & Quick Starts

2.3 Hardware Installation Procedure

To install a MR4800E, perform the following steps.

Step Procedure

1. Unpack the MR4800E from its packaging and perform a visual inspection of the hardware. If
you are concerned about the condition of your MR4800E, call Technical Support.

2. Remove the blank controller panel or your MR4800 controller from the CC4800 rack. The
MR4800 and MR4800Es are hot-swappable.

3. Holding the MR4800E by its U-bolt and the bottom panel, place the MR4800E into the open
slot of the CC4800 rack. Make sure the side rails of the MR4800E mate properly with the
plastic guides of the CC4800.

4. Slide the MR4800E into the CC4800 rack until you feel the MR4800E connector contacts the
socket at the back of the CC4800 chassis.

5. Tighten the MR4800E retaining screw.

6. Turn the PS4800 power switch On (to the | position).

7. Observe the PS4800 "Outputs Good” LED. If not lit, refer to Chapter 5 of this manual. If lit,
proceed with MultiModemManager operation (Chapter 4 of MultiModemManager Owner’s
Manual).

Note: A self-test is run each time the MultiModem Manager is powered on. Refer to Chapter 5 of the

MultiModemManager Owner’s manual for more details on the power on self-test

.

2.4 Ethernet Cabling

The CC4800 rack front panel contains one female RJ-45 connector. This connector is used to
connect the MR4800E to an Ethernet network running TCP/IP. This connector must be connected to
the TCP/IP network that the management console (running the MultiModemManager software or
optionally , a third-party SNMP manager) is to be run on in order for the MR4800E to be configured.

2.5 Serial Cabling

If you wish to connect the CC4800 rack to the TCP/IP network using a serial link (i.e., via PPP or
SLIP) instead of using the Ethernet link, the 9-pin connector on the front panel of the MR4800E can
be used.

There is a 25 pin RS-232 port located behind the power supply on the back of the CC4800 rack that
is used for performing diagnostics and configuration.

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).

3.2 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).

Supervisor Operator Guest

Security Level

Default User ID
Default Password

Once logged in you can change your user identification and password
USERID - Allows you to change your user identification
P ASSWD - Allows you the change your password

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.

Can perform Can perform Can only
all management non-destructive view information
commands management

commands
supervisor operator guest
supervisor operator guest

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.

16

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 .

3.5 Command Line Interface

The MR4800E provides a complete command line interface so that you can do most of your
management functions through either the MR4800E diagnostic serial connector or (more likely) by
using Telnet. When first setting up your MR4800E you must use the MR4800E diagnostic serial
connector to set up the system's TCP/IP information (such as it's IP address, Default Gateway IP
address, etc., as specified in the MR4800E Quick Start in Chapter 2).

When you first come up, either in Telnet or by using the serial port, you will be prompted for a user id
and password. Enter in the correct user id and password for the desired security level (see above for
a description of the security levels). Once logged in, the screen should show the following
information.

Chapter 3 - Hardware Operation

Password *********

The command line prompt is the current directory followed by a '#' character. There are two drives
formatted on the MR4800E, A and B, and you can switch between them by using the CD command or
by typing A: or B:. A standard set of DOS and UNIX file system commands are available, albeit in
limited fashion (no wildcards are supported, etc.). See Chapter 4 for the command reference to see
how each of the commands are supported.

There are commands that allow you to monitor activity on the modems in the rack. The commands
GETMODEMS, GETCALLS, and GETFAULTS allow you to see the current state of the modems, the
connection history of the modems and the history of faults on the modems, respectively .

Information that is displayed which goes beyond the size of the screen, will be output a page at a
time using a "--MORE--" prompt. When you get this prompt, you have the option of quitting the list by
typing "Q" or continuing the list by typing anything else.

There are commands that allow you to change the current state of the modems. With the commands
OOSSET, OOSCLEAR, RESET, CONFIG, you can set modems in or out of service; reset them or
configure them, respectively .

LOGOUT should be used when you are done using the command line interface so that the MR4800E
is left in a secure state.

See Chapter 4 for a complete list of the commands that are available for use.

17

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.

3.7 Web Browser Interface

The MR4800E can be monitored/controlled from a Web browser such as Netscape Navigator version

2.0 or later or Microsoft Internet Explorer version 3.0 or later.
There are two main interfaces available: a HTML framed interface (where the browser screen is split

into Frames holding different information ) and a Non-Framed interface. To get to the framed interface
type in the following URL in your browser’s URL entry line and hit enter.

http://1 11.222.333.444/mmm/main.html

For the Non-Framed interface, use the following URL:

http://1 11.222.333.444/mmm/standard.html

where 1 11.222.333.444 is your card’s IP address.

3.7.1 Logging In

Whenever you access the MR4800E for first time during a browser session (since the browser
program was run), you will be prompted for a user ID and password. You must login as someone of
operator level of security or higher to get access to the Web interface.

Once logged in both interfaces present the users with a list of available views (Framed or Standard),
a list of operations, and a list of information views. These are all available via HTML hot-links.

3.7.2 Getting Modem Information

In each interface the same information is available in table format. There are tables of information
about modems, calls on modems, modem faults and system faults, and system version. In the
framed version these tables appear in each of the frames, in the non-framed version each of the
tables appear on a separate HTML page.

3.7.3 Controlling Modems

In each interface, the user can also reset modems, set in/out-of service modems, and configure
modems. When the user selects the hot-link for that operation, they are presented with a form where
they enter (in list format - e.g., 1A:3C,15B) which modems are to have the desired operation
performed on them. After entering this list, the operation is performed when the user selects the
“action” button (e.g., Config if the user is configuring modems).

3.7.4 Web Interface Limitations

The Web interface does not provide the full management interface at this point (full management is
provide either through our MultiModemManager software, or through the use of a 3rd Party SNMP
manager). Once the system is set up though, most management can be done using the Web
Browser interface.

18

Chapter 3 - Hardware Operation

3.8 FTP Interface

FTP (File T ransfer 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. If you wish to analyze event information, you will need to transfer event files (*.hr) from the
MR4800E to your system where you can run the Statistical Analyzer on them.

Note: When logging in, you must use the Supervisor user name and password.

3.9 PPP Interface

PPP (Point-to-Point Protocol) is an Internet standard protocol that allows TCP/IP connections over a
serial data link. The 9-pin serial connector on the front of the MR4800E is for a PPP connection to
the MR4800E.

Chapter 5 - Troubleshooting

MR4800E Owner’s Manual

5.1 Introduction

This chapter provides the information needed to identify and fix problems with the MR4800E.
Problems can be observed at the MR4800E front panel (LEDs), or the dedicated management

console's PC screen. In addition, problems can be found when performing the Diagnostic Tests,
documented in Chapter 8 of the MultiModemManager Owner’s Manual.

For specific MultiModem troubleshooting information, refer to the MultiModem Owner’s Manual
shipped with your MultiModem. For basic Windows messages, refer to your Windows documentation
or Help screens.

5.2 LED Indicators

The MR4800E front panel has the following indicators.

• MR4800E two-color LEDs (1-16)

• Ethernet status LEDs (1-4)

5.3 Front Panel Indicators

There are 16 two-color LEDs on the front panel of the MR4800E. The LEDs indicate the state of the
installed modem cards in each of the CC4800 rack's 16 slots. On power up the lights go through a
defined sequence of events before they act as status indicators for the modem cards. This sequence
is defined below:

1. The LEDs on the right side turn red and then turn green when the right SIMM passes it's
memory test.

2. The LEDs on the left side turn red and then turn green when the left SIMM passes it's
memory test.

3. The LEDs stay green for about five seconds while the flash boot code waits for a handshake
sequence on the diagnostic serial port.

4. If none is detected (this is normal unless the firmware is being updated through the
diagnostic port) the main controller code starts running and the LEDs are turned off.

5. The LEDs are turned on and off, one at a time, red and green.

6. All LEDs turn green while the system starts up.

7. When the system has started, the LEDs reflect the status of the modem cards.

After the system has started, each LED will be in the following state based on the status of the
modem card.

LED Color Modem Card Status

Off Card not installed
Green Card installed and all modems are communicating with the MR4800E
Red Card installed and none of the modems are communicating with the MR4800E
Flashing Red/Green Card installed and one or two modems are not communicating with the

MR4800E

56

5.4 Ethernet Status LEDs

The MR4800E front panel contains four Ethernet status LEDs. Each LED is described below.

LED Color Status

Link Integrity (LI) yellow on during good link
Collision Sense (CS) red on when there's a collision on Ethernet
Transmit (TX) green on during Ethernet transmit
Receive (RX) green on during Ethernet receive

5.5 MR4800E Diagnostic Tests

If you suspect that your MR4800E is not functioning properly , you may run the following diagnostic
tests to test the MR4800E's hardware capabilities.

1. Put test jumper (refer to page 2-1 of the owners manual to locate the test jumper on the
controller card) into loopback position (so the two pins are shorted together). Plug the
10base-T loopback jumper into the front Ethernet connector of the MR4800E card.

2. Use MultiExpress (or any data comm package) running at 115,200 with no flow control.
Connect the COM Port associated with the data comm package to the RS-232 port on the
back of the CC4800 rack.

3. Reset the MR4800E by pressing the reset button on the front with a paper clip or power the
CC4800 rack off and on.

4. When prompted to start manually , press a key.

5. You will be prompted to enter a username and password. Login as supervisor.

6. Type in the command HDTEST and press Enter.

7. You will see a menu. Proceed with testing in the following order:
WARNING: Running options either out of order or ones not specified may cause

unpredictable results.

Chapter 5 - Troubleshooting

Test 2 Red LED’s on
Test 3 Green LED’s on
Test 4 All LED’s off
Test 5 Flash memory test
Test 7 Ethernet loopback test

Watch for the green Ethernet LED on left side of the Ethernet connector, it should be on
solid. Numbers stopped and packets received will match.

Test 1 Start backplane LED’s on the front of the MR4800E will reflect the

number of cards installed.
Test a Sets slot 1 modems to 9600 bps
Test b Sets slot 1 modems OOS
Test c Clears slot 1 modems OOS
Test d Resets slot 1 modems
