CRS2F31xx-100

Slide-in-Module Media Converter

RS-232 to Fiber

Transition Networks CRS2F31xx-100

series media converters are designed to

be installed in the PointSystem™ chassis

and connect copper RS-232 cable to

fiber-optic cable at asynchronous data

rates up to 115 kB/s.

The CRS2F31xx-100 is designed to be

installed in pairs where one is the local

media converter and the other is the

remote.

* Typical maximum cable distance. Actual distance is dependent upon the

physical characteristics of the network installation.

The stand alone version of the media converter is SRS2F31xx-100. For more

information, see the SRS2F31xx-100 user’s guide on-line at:

Installation

CAUTION: Wear a grounding device and observe electrostatic discharge

precautions when setting the switches and jumper. Failure to observe this

caution could result in damage to, and subsequent failure of, the media

converter.

Set the DTE/DCE Switch

The DTE/DCE switch is located on the side of the media converter. How the

DTE/DCE switch is set depends on the type of device connected to the media

converter:

•DTE (Data Terminal Equipment).

•DCE (Data Communication Equipment).

... and the type of RS-232 cable:

•Straight-through configuration cable.

•Null-modem configuration cable.

CAUTION: Wear a grounding device and observe electrostatic discharge

precautions when setting the hardware/software jumper and installing the media

converter. Failure to observe this caution could result in damage to, and

subsequent failure of, the media converter.

Set the Hardware/Software Jumper

• The jumper is located on the circuit board.

• Use small needle-nose pliers to set the jumper.

Hardware The media converter mode is determined by

the switch settings (see pages 2-3).

Software The media converter mode is determined by

the most-recently saved, on-board

microprocessor settings.

Installing the Slide-in-Module

To install the CRS2F31xx-100 media converter slide-in-module:

1. Locate an empty installation slot on the PointSystem™ chassis.

2. Carefully slide the slide-in-module into the installation slot, aligning the

module with the installation guides.

3. Ensure that the module is firmly seated inside the chassis.

4. Push in and rotate the attached panel fastener screw clockwise to secure

the module to the chassis front.

SNMP

Use SNMP at an attached terminal or at a remote location to monitor the

media converter by monitoring:

• Local/remote fiber link status

• Local/remote hardware/software mode

• Local/remote loop-back

Also, use SNMP to enter network commands for:

• Local/remote loop-back

See the on-line documentation that comes with Transition Networks

FocalPoint™ software for applicable commands and usage at

www.transition.com.

Remote Management

The CRS2F31xx-100 can remotely manage the SRS2F31xx-100 (the stand-

alone version of the media converter) or another CRS2F31xx-100. For

example, a local CRS2F3111-100 converter (that is installed in a managed

Transition Networks PointSystem™ chassis) is connected, via fiber, to a remote

SRS2F3111-100 converter.

The SNMP section (below) lists the commands that can be used to monitor and

manage both the local and remote media converter.

NOTE: In a managed network, both the local and remote media converters

must be set to “software” mode (see page 4).

Troubleshooting

If the media converter fails, isolate and correct the failure by determining the

answers to the following questions and then taking the indicated action:

1. Is the P(power) LED illuminated?

• Is the media converter inserted properly into the chassis?

• Is the power cord properly installed in the chassis and in the grounded AC

outlet?

• Does the grounded AC outlet provide power?

• Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.

YES

• Proceed to step 2.

2. Is the RX (copper) LED flashing?

• Disconnect and reconnect the RS-232 copper cable to restart the initialization

process.

• Restart the attached device on the other end of the RS-232 cable to restart the

initialization process.

• Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.

YES

• Proceed to step 3.

3. Is the FL (fiber) LED illuminated?

• Check the fiber cables for proper connection.

• Verify that the TX and RX cables on the media converter are connected to the

RX and TX ports, respectively, on the other media converter.

• Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.

YES

• Proceed to step 4.

4. Is the FL (fiber) LED flashing?

YES

• The media converter is in loop-back mode. To disable the loop-back function

in “Hardware” mode, set the loop-back switch to the "Norm" position. In

“Software” mode, at the SNMP interface, select “disable loop-back” option.

• Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.

• Proceed to step 5.

CRS2F31xx-100

5. Is Data Transfer Failing?

YES

• Verify the local copper connection by starting a local copper loop-back

(hardware mode: set the loop-back switch on the local media converter to

“loop”, software mode: enter the local copper loop-back command) and then

use a bit error test unit to run a bit error test.

• Verify the local fiber connection by starting a remote fiber loop-back (hardware

mode: set the loop-back switch on the remote media converter to “loop”,

software mode: enter the remote fiber loop-back command) and then use a bit

error test unit to run a bit error test.

• Verify the remote copper connection by starting a remote copper loop-back

(hardware mode: set the loop-back switch on the remote media converter to

“loop”, software mode: enter the remote copper loop-back command) and

then use a bit error test unit on the remote end to run a bit error test.

• Verify remote fiber connection by starting a local copper loop-back (hardware

mode: setting the loop-back switch on the local media converter to “loop”,

software mode: enter the local fiber loop-back command) and then use a bit

error test unit on the remote end to run a bit error test.
