Preface
This user’s guide is intended for the network administrator responsible for
installing, configuring, using, and maintaining a Transition Networks
16-Slot Media Conversion Center. A working knowledge of local area
network (LAN) operations, including familiarity with communications
protocols used on interconnected LANs, is assumed.
16-SLOT MEDIA CONVERSION CENTER v

1. INTRODUCTION
The modular Transition Networks E-MCC-1600 16-Slot Media Conversion
Center allows the network administrator to select from among Transition
Networks Media Converter Slide-in-Modules, to install the Media
Converter Slide-in-Modules in the Media Conversion Center chassis, and
then to connect various network media, at a central wiring location,
through the Media Converter Slide-in-Modules.
If a Management Module is installed in the Media Conversion Center, the
network administrator also can use a remote Network Management
Station to monitor the status of the Media Conversion Center and of any
installed Media Converter Slide-in-Modules.
As network conditions change, the network administrator can add or swap
Media Converter Slide-in-Modules, install a redundant Power Supply
Module (if not originally configured and installed) and/or install the SNMP
Management Module (if not originally configured and installed).

ETHERNET PORT, through which the Management Module communicates
with a remote Network Management Station (NMS), are available at the
Management Module installed at the back of the Media Conversion Center.
NOTE: Connectors to network media are located on each Media
Converter Slide-In-Module installed at Media Conversion Center front.
Power and Reset Switches
POWER ON/OFF switches are located on each Power Supply Module
installed at the Media Conversion Center back.
A RESET switch is located on the Management Module installed at the

1.3 The Media Conversion Center in the Network
Using Media Converter Slide-in-Modules installed in the 16-Slot Media
Conversion Center, the network administrator can connect various
network media at a central wiring location
As new media are added to the network, the network administrator can
install new Media Converter Slide-in-Modules to support the changed
network requirements.
1.4 Optional Network Management
The optional E-MCC-MM Management Module, which can be installed in
the back of the Media Conversion Center, has the following key features:
• SNMP Management Agent
• Command Line Interface
1.4.1 SNMP Management Agent
The SNMP Management Agent feature permits the network administrator
to monitor the state of the LEDs on the front of the Conversion Center (and
thus the condition of the network resources supported by the cards
installed in the the Conversion Center) from a remote location.
SNMP Management requires the use of any SNMP-compliant NMS
(Network Management System) software product, such as Hewlett-
Packard’s OpenView™, installed on a computer at a remote location. The
Management Module must be attached to a network that is accessible (via
IP) from the the NMS computer.
1.4.2 Command Line Interface (CLI)
The CLI is analogous to a Unix shell prompt. It has the following features:
• Allows the network configuration of the Management Module (such as
its IP address) to be configured and saved.
• Can be used as an alternative to an SNMP NMS: The CLI Allows all
management data that is available via SNMP to be viewed and (where
applicable) altered. A quick summary of the Conversion Center’s
status is available, or any individual SNMP MIB variable supported by
the Management Module can be viewed or changed on command.
• Diagnostic commands are available from the CLI. These commands
facilitate troubleshooting of the Management Module and even of
other stations on the network.
• Allows maintenance of the Management Module. (e.g. firmware
upgrade)
The CLI is accessible through two different physical interfaces: The
Management Module’s Serial Port, and its embedded Telnet Server. The
same interface is presented by these two methods, aside from a few
restrictions placed on Telnet access. The benefits and shortcomings of
each are discussed in the following sections.
1 INTRODUCTION
1.5
16-SLOT MEDIA CONVERSION CENTER

1.4 Optional Network Management (continued)
CLI Access via Serial Port
The Management Module’s CLI can be reached through Telnet or through
the module’s serial port.
The choice of the serial port path recommended or required in the
following circumstances:
• When the IP configuration of the Management Module needs to be
set up or changed. Initial IP configuration is most commonly
performed through the CLI via the serial port. Subsequent IP
configuration changes via Telnet are supported, but strongly
discouraged (for reasons discussed elsewhere).
• When a firmware upgrade needs to be performed – Firmware
upgrade via the network is not supported.
• When best possible performance is desired, as during a troubleshoot-
ing session.
To access the CLI via serial port, a serial terminal (or a computer with a
terminal emulator) must be attached to the the Management Module’s
serial port via a null modem cable. (See Section 4. OPERATION.)
CLI Access via Telnet
CLI Access via Telnet is useful when CLI access is desired from a physical
location other than the wiring closet where the E-MCC-1600 is installed.
Any standard Telnet client (such as the one that is included with Windows
95) can be used from any location on the network.
The following notes apply to CLI access via Telnet:
CAUTION: IP configuration changes take effect immediately when
commands are received. Therefore, these changes should not be
made via Telnet unless the user is confident that the implications of
this are fully understood and have been compensated for. (NOTE:
The same warning applies to any attempt to make IP configuration
changes via SNMP.)
CLI messages specifically related to Telnet or its underlying protocols
are filtered out by the Telnet server to prevent storms of messages.
Therefore, Telnet troubleshooting should always include inspection of
the CLI at the serial port interface.
Firmware upgrades cannot be performed via Telnet; serial port CLI
access is required.
1.6 E-MCC-1600

Telnet Security:
The Telnet password is the same as the private community name. This is
so because the authority granted to the Telnet CLI is not significantly more
than that provided by the “private” (i.e. most priveleged) MIB view. Note
that network traffic carried by the devices installed at the front of the
Conversion Center can not be disturbed even through the most priveleged
access to the Management Module. The worst-case scenario is that remote
access to the Management Module itself can be interrupted.
By default, the Telnet server will accept a connection from any client that
provides the correct password. However, through the use of the CLI
commands “TNTRIP” and “TNTRIPMASK,” the server can be configured
to restrict access to clients on a particular subnet or a single specific
station, or it can be disabled altogether.
The Telnet server only supports a single connection at any given time.
Additional concurrent connections attempts are rejected.
A character mode Telnet client is preferred, but not required.

2 SITE PLANNING
The site for the 16-Slot Media Conversion Center must provide the
following:
• Power outlet for each Power Supply Module in the 16-Slot Media
Conversion Center
• Adequate ventilation
• Standard environmental conditions
• Isolation from electrical noise, including radio transmitters and
broadband amplifiers, motors, high power electrical lines, or
fluorescent light fixtures.
Additionally:
• Twisted pair cables should not run in the same conduit with power
line cables
• Phone lines should be separated from data cables
• Flat or “silver satin” wires should not be used.
