SNMP Manageable Media Converter
Software Installation Guide
This manual details the installation of the Developer’s SNMP files
required to set up and manage the SNMP Master Management
Module of an SNMP Manageable Media Converter.
MIB Utilization
SNMP Media Converter utilizes the following MIBs, which can be
found in the root directory on SNMP Support Disk 1 included with
the SNMP Master Management Module:
MIB-I/MIB-II
The following components must be installed and/or set before
installing the Developer’s SNMP files:
• SNMP-manageable device (i.e. SNMP Media Converter
chassis). Refer to the installation manual included with your
SNMP Media Converter chassis for further details.
• Execution of HUBCTRL 32 on the Management PC for setting
the TCP/IP information in the SNMP Media Converter device
(ie: IP address, subnet mask and default gateway). Refer to
the HUBCTRL 32 Help file for information.
In addition to the above, extra community and trap information
may need to be configured. Although not required, it is
recommended that these stages be completed. Refer to the
HUBCTRL 32 Help file for information.
NOTE: ‘Management PC’ refers to the PC that will run HUBCTRL
32 for the initial configuration and/or where the SNMP network
management software will be installed.
In order for the SNMP Media Converter to be managed, the
following stages need to be completed in the Management PC:
• Installation of a TCP/IP stack compatible with the SNMP
management software being used
• Installation of the SNMP network management software
(NMS)
• Integration of the Developer’s MIB into the SNMP
management software
NOTE: The PC intended for use as the Management PC must
conform to the MINIMUM hardware and software requirements
of the management software being used.

MCIMC MIB
SNMP statistics, transport protocol orientated
statistics (IP, ICMP, UDP, TCP), information
collected on frames sent to/from the MAC
interface.
NOTE: Only on managed hubs or switches.
Enterprise specific information for the SNMP
Media Converter (i.e. conversion chassis and
module types, link fault, power supply fault,
chassis lost, etc.).
Installing SNMP Files into Management Software
The SNMP management protocol is an industry standard. Any
management software which is 100% compatible with the SNMP
standard can manage any device which is also 100% compatible
with the same standard.
Management information for SNMP Media Converters, such as
which modules are installed and the status of ports, can be ‘seen’ by
browsing the MIB information to which the management software
has access.
In order to successfully manage an SNMP Media Converter, ALL
OF THE MIBs mentioned in the MIB Utilization section need to be
integrated into the management software. The MIBs are included on
SNMP Support Disk 1 (supplied with the SNMP Master Management
Module).
The majority of management packages have a function known as a
MIB Compiler. This function reads in the MIB information and
converts it to machine-readable format. Refer to your management
software documentation about how MIBs are integrated into the
software.
The information held within the SNMP Media Converter can be
retrieved by using the MIB Browser function of the management
software.
2
In addition to integrating the MIB information, please ensure that
the community strings configured in the SNMP Media Converter are
also the ones used by the management software. Failure to do this
will result in the inability to SET or retrieve MIB variables. Refer to
the HUBCTRL 32 Help file for information on setting the values for
the SNMP Master Management Module.
Once the MIB compile is complete and the management software
has ‘discovered’ the SNMP Media Converter, complete the following
stages using the MIB Browser to ensure that the MIBs are installed
correctly and the SNMP Media Converter is responding to the SNMP.
1. From the SYSTEM group of MIB-I/MIB-II, GET the variable
sysDescr.0. This should return the following information:
Black Box SNMP-Manageable Media Converter
2. From the SYSTEM group of MIB-I/MIB-II, SET the variable
sysContact.0 to your name.
3. From the SNMP Media Converter group of the MCIMC MIB,
get the value of the variable productName.1. A text value
corresponding to the type of chassis in use should appear.
If any of the above fails, please note the error message, the type of
management software being used and call Technical Support for
assistance.
Viewing and Configuring the MIB Information
As stated earlier, the management software of an SNMP Media
Converter allows you to monitor and control the port status from a
single Management PC. You can also enable and disable LinkLoss
and FiberAlert features as well as easily identify lost links and power
supply failures.
NOTE: Refer to your management software’s documentation
regarding the MIB Browser function for complete information on
its use.
Once you have installed your SNMP Files into your MIB Browser,
you can view the SNMP Media Converters in your managed network.

Giving Descriptions to SNMP Media Converters and Ports
After installation of your SNMP Files into your MIB Browser, you
should give each SNMP Media Converter and each port on each
module within the unit a description for easy identification. For
example, you can enter the description of an SNMP Media Converter
as “Gadwick Dorm” to indicate the SNMP Media Converter is located
in Gadwick Dorm. The description of the port should typically
identify what the port is connected to. For example, on an SNMP
TP/FO module, you can enter the description “Catalyst5000 Port 3”
for the twisted pair port and “Smith’s Office” for the fiber port. You
can change these descriptions at any time.
Adding/Changing Unit Descriptions
Use the MIB Browser function in your management software to
add/change the description of one or more SNMP Media Converters
in a group.
There are several values that may need to be set.
Node Name — This is the symbolic name given to the SNMP
Media Converter during installation
Variable Name — This is the generic name in the database
given to the device (i.e. mcUnitUnitDescr.1);
or the generic name given to a port
(i.e. mcPortPortDescr.1.3.2)
Variable Value — This is the descriptive name you give to your
device/port. This name must be 24 characters or less
including spaces and punctuation. The description will
always appear in upper case.
To add/change the description of an SNMP Media Converter, move
to the directory in the database where the names/descriptions for the
devices are stored. The path is:
private\mediacon\mcUnitTable\mcUnitUnitDescr
The default name for the Master SNMP Media Converter is
mcUnitUnitDescr.1. For the Variable Value, enter the description you
wish the Master SNMP Media Converter to have (i.e. Mktg Depart in
Owen Hall).
If you want to add/change the description of a Slave SNMP Media
Converter, change the number in the Variable Name to 2
(i.e. mcUnitUnitDescr.2) or the corresponding number to the unit
4
you want to change (2 for the first Slave SNMP Media Converter, 3
for the second Slave SNMP Media Converter, etc.). Enter the desired
description. Repeat this for each device for which you are
adding/changing its description.
Adding/Changing Port Descriptions
Use the MIB Browser function in your management software to
add/change the description of one or more of the ports on an SNMP
Media Converter.
To add/change the description of a port, move to the directory in
the database where the names/descriptions for the ports are stored.
The path is:
private\mediacon\mcPortTable\ mcPortPortDescr
The Variable Name represents the port whose description you
want to alter. The first number represents the SNMP Media
Converter, the second number represents the module and the third
number represents the port on the module. For example, the
Variable Name mcPortPort.3.5.2 is the name for Port 2 on the fifth
module in the second Slave SNMP Media Converter.
NOTE: The number of the module is associated with the slot in
which the module is installed. The slots are numbered, left to
right, one through six on the top and seven through 12 on the
bottom of an SNMP Telco Media Converter. The slots are
numbered, left to right, one through three on the top and four
through six on the bottom of an SNMP 6-Slot Media Converter.
If there is more than one port on a module, Port 1
corresponds to the port on the left and Port 2 corresponds to the
port on the right of the module (front view). With an SNMP Telco
Media Converter, Port 1 is always the Telco port.
To add/change the description for a port, make sure the number in
the Variable Name reflects the number associated with the port
whose description you want to alter. Enter the desired description for
the Variable Value. Repeat this for each port for which you are
5
adding/changing its description.
Enabling/Disabling a Feature or Port
At times, you may need to disable a port if there is too much
traffic on the network or for system administration, etc. You can
enable/disable ports within the software. The features LinkLoss and
FiberAlert can also be enabled/disabled within the software but to do
so the jumpers for these features must be in the disabled position on
the module (refer to the installation manual for the SNMP
Manageable Module for more information). FiberAlert should only
be enabled on one side of a media conversion.
Enabling/disabling a feature and a port are virtually the same. Use
the MIB Browser function in your management software to enable/
disable ports and features.
Port Information
Use the MIB Browser function to monitor port status. Because the
management software only polls the SNMP Media Converter every
few seconds, the software only reflects functions/features that are
constant. For example, the link of a twisted pair port will be up as
long as the port is connected to another device and is functioning
properly. On the other hand, you will not be able to monitor when
there is traffic on the segment, etc. Use the LEDs (documented in
the installation guide included with the SNMP Manageable Module)
on the device itself to monitor such information.
Traps
Traps are sent by the manageable device to a management PC
when a certain event takes place. Refer to the HUBCTRL 32 Help
file for information regarding configuring traps. You must also
configure your management station to display traps from the
managed device.
Troubleshooting
The following are troubleshooting guidelines for some of the more
common problem situations that may occur.
A Link is Down
If one of your ports is down, check the connectors and make sure
6
they are plugged in completely. Also make sure you are looking at
the right module within the chassis.
Slave SNMP Media Converter Stops Responding (Chassis Lost)
Make sure cables are still connected between the Master SNMP
Media Converter and Slave SNMP Media Converters. Verify that the
Master SNMP Media Converter is showing LEDs for all active Slave
SNMP Media Converters.

The Master SNMP Media Converter may need to be restarted to
rediscover the Slave SNMP Media Converters if there is a loss of
connection between the chassis. This loss could occur as a result of
cable disconnection or power loss to the chassis. Before restarting
the Master SNMP Media Converter, ensure that all cables are
connected and power is supplied to all the Slave SNMP Media
Converters in the group.
SNMP Media Converter Group is Not Responding
Ensure that the connection to the network is good. Make sure the
Master SNMP Media Converter is connected to the network and is
powered up. Also, verify that the IP address information is correct
(refer to the HUBCTRL 32 Help file for information). Cycle power on
all chassis in the group.
NOTE: The Master SNMP Media Converter needs to be powered
up last.
You can also try disconnecting the first Slave SNMP Media
Converter from the Master SNMP Media Converter and see if the
Master SNMP Media Converter comes up. If the Master SNMP Media
Converter does come back up, the problem probably resides
between the Master SNMP Media Converter and that Slave SNMP
Media Converter. If the Master SNMP Media Converter does not
come back up, reconnect the first Slave SNMP Media Converter and
disconnect the second Slave SNMP Media Converter. Repeat this for
each Slave SNMP Media Converter in the group to verify that all
connections are functioning properly.
