Overview This document contains instructions necessary for the installation and operation of the Perle Fast Ethernet Media Converter Module(s) (C-100 and CM-100) that are used in conjunction with a Perle MCR Chassis. The C-100 are unmanaged media converter modules, and the CM-100 are the managed versions. These products convert a 100Base-T cable connection (copper) to a 100Base-X connection (fiber). The fiber connection can be either single mode (SM) or multimode (MM) and can operate ove

Installation The module comes equipped with a bank of DIP switches and jumpers for setting configuration. The default DIP switch settings (all switches in the UP position) and jumper settings will work for most installations.. The following steps are used to configure the Perle Fast Ethernet Media Converter Module: 1. Set the Auto-MDIX jumper (optional). 2. Set the Auto-Config jumper (CM-100 only) (optional) 3. Set the DIP switch settings (optional). 4. Insert the Media Conve

Auto-Config Jumper (CM-100 only) The Auto-Config jumper (J6) is located just below the Auto-MDIX jumper (see above). Refer to the diagram below for labelling. This jumper only applies to CM-100 modules. Strapping pins 1 and 2 of the jumper will set the module in SW mode and strapping pins 2 and 3 will set it in Auto Config mode. Auto: When set to Auto the module will, at power-up, check its internal flash memory to see if configuration information has been downloaded to it from a ma

DIP Switches DIP Switch Settings Auto Negotiation (Switch 1) Switch Mode Position Up (default) Auto Down Off Auto: In this mode of operation the Media Converter Module will negotiate Ethernet parameters on the copper connection. This will ensure the most optimal connection parameters will be in effect. If the copper link partner does not support Auto negotiation, the C-100 and CM-100 will default to 100 Mbps and Half Duplex mode. Off: Auto Negotiation should only be turn

Link Mode (Switch 2) Switch Mode Position Up (default) Link Pass-Through Mode Down Standard Mode Link Pass-Through: In this mode, the link state on one connection is directly reflected through the Media Converter Module to the other connection. If link is lost on one of the connections, then the other link will be brought down. With Media Converters on both ends of the fiber link and both setup for Link Pass-Through, then a loss of copper link on the far end device will propaga

If the Media Converter has been set to Link Pass-Through mode, the effect will be the same as FEF, since the link loss on the fiber receiver will bring down the copper link, which will in turn cause the transmit fiber link to be brought down. Note: If it is required to either generate or detect the FEF signal, then the FEF switch needs to be set. Disabled: The Media Converter Module will not monitor for, or generate Far End Fault. The following diagram is an illustration of the opera

Unused (Switch 4) Pause (Switch 5) Switch Mode Position Up (default) Enabled Down Disabled Enabled: When Auto Negotiation has been set to Auto (SW 1), the Media Converter Module will use this setting for its Ethernet parameter negotiation on the copper connection. Disable: The Media Converter Module will not negotiate support for the Pause feature. Note: The Media Converter Module will not act on, or generate any Ethernet Pause messages, but will pass them through to the end

Installing or Replacing Media Converter Modules Caution: Observe electrostatic discharge precautions when installing the Media Converter Module(s) into the Chassis. Failure to observe this caution could result in damage to the Module(s) and/or chassis. The Perle Media Converter Modules can be installed in any available slot and in any order within the MCR Chassis. Installing or Replacing a Media Converter Module 1. Remove the Media Converter Module from its packaging. 2.

7. Remove the dust cap from the fiber connector and connect the fiber and copper cables. Removing Media Convert Modules 1. Loosen the captive retainer screw on the front of the Media Converter Module and gently pull the module out. 2. If not inserting a replacement Media Converter Module, cover the opened slot with a face plate and secure the screw. Installing the Duplex Fiber Cable Locate a 100Base-X compliant duplex (2 strands) fiber cable with the appropriate connectors. Co

Installing the Simplex Fiber Cable • Locate a 100Base-X compliant simplex (1 strand) fiber cable with appropriate connectors. • Connect the fiber cable from one Media Converter Module to another Media Converter/switch/fiber device. Installing the Copper Cable • Locate 100Base-TX compliant copper cables with male, RJ- 45 connectors installed at both ends. • Connect the RJ-45 cable between the Perle Media Converter Module and the device. Note: The Perle Media Converter Module su

Operation Status LED The Perle Fast Ethernet Media Converter modules have three single color status LEDs located on the face plate of the module. PWR - Power/Test • On: Power is on, module operating normally. • Blinking slowly: the module is in loopback mode. • Blinking quickly: the module has a hardware error. LKF - Fiber Link/Activity • On: Fiber link present. • Blinking quickly: Fiber link present and receiving data. • Off: No fiber link present. LKC - Copper Link/Act

Other Features Auto-MDIX: Auto-MDIX (automatic medium-dependant interface) detects the signalling on the 100BASE-T interface to determine the type of cable connected (straight-through or crossover) and automatically configures the connection. Error Recovery: In certain configurations, and under specific conditions where the Media Converter Module brings down a link to convey status, there is potential for a deadlock. Recovery is achieved by momentarily restoring the link to se

Troubleshooting General • Ensure the module is correctly seated to the backplane in the MCR Chassis. The PWR LED should be on solid. • Ensure both devices on either end of the fiber are compatible. If using a simplex fiber connection, ensure that you have both an Upstream (U) and Downstream (D) Media Converter. • Ensure all cabling is of the correct type and is in good working order. • For duplex fiber connections, ensure the RX and TX has been reversed between the two Media Convert

Method 2: The fiber connection can also be verified by configuring the remote Media Converter for loopback mode. The LKF LEDs on both Media Converters should be lit. Data should pass through the local converter, over the fiber connection to the remote Media Converter. At the remote Media Converter, the data will be looped back and passed through the fiber, once again, to pass through the local converter to the copper link. Note: If troubleshooting a CM-100, setting the Auto-Config jum
