Installation
CAUTION: Wear a grounding device and observe electrostatic discharge precautions when setting the switches and jumpers. Failure to observe this caution could result in damage to, and subsequent failure of, the media converter.
Set the Terminal Timing Switch
The 16-position terminal timing switch, located on the side of the media converter’s circuit board, allows the network administrator to configure the media converter for various network conditions.
To set the terminal timing switch, insert a small, flat-blade screwdriver or a similar device into the recessed arrow on the switch. Gently rotate the switch to the position required for the site installation.
The table below lists the conditions for each setting of the terminal timing switch:
* Setting “F” overrides the software mode (see page 6) and sets the media
converter to asynchronous mode.

Installation -- Continued
Set the Loop-Back Switch
The loop-back switch is located on the front panel of the media converter and is used to debug network faults. (See “Troubleshooting” section for
examples.)
To set the switch, use a small flat-blade screwdriver or a similar device.
Norm Set the switch to “Norm” for
normal operation.
Loop Set the switch to “Loop” to
enable both fiber and copper loop-back.
The two drawings below illustrate the data path for both normal mode and loop-back mode:

Installation -- Continued
Set the Jumpers
The CPSVT26-10x has three jumpers located on the circuit board. To set any of the three jumpers, use small needle-nosed pliers or similar device to move the jumper(s) to the desired position(s). (See pages 6 and 7.)
Hardware/Software Jumper (J4)
The Hardware/Software jumper (J4) is located on the circuit board and is the jumper that is nearest the rear connector of the media converter (see the photo to the right).
Hardware The terminal timing switch
controls the terminal timing function. The loop-back switch controls the loop-back function.
Software The terminal timing switch and
the loop-back switch are disabled. These two functions are controlled by the most­recently saved, on-board microprocessor settings.
NOTE: Setting the terminal timing switch to “F” overrides the software mode and sets the media converter to asynchronous mode. (See page 4.)
Remote Management
The CPSVT26xx-10x can remotely manage the SPSVT26xx-10x (the stand­alone version of the media converter) or another CPSVT26xx-10x installed in a Transition Networks PointSystem™ chassis.
For example, a local CPSVT2611-100 converter (that is installed in a managed PointSystem™ chassis) is connected, via fiber, to a remote SPSVT2611-100 converter. An example of a managed single-fiber network has a local CPSVT2629-100 converter connected, via fiber, to a remote SPSVT2629-101.
The SNMP section (on page 9) lists the commands that can be used to monitor and manage both the local and remote media converters.
Note: In a managed network, both the local and remote media converters must be set to “software” mode (see above).

Install the Slide-In-Module
CAUTION: Wear a grounding device and observe electrostatic discharge precautions when installing the CPSVT26xx-10x slide-in-module media converter. Failure to observe this caution could result in damage to, and subsequent failure of, the media converter.
1. Carefully slide the slide-in-module into the installation slot, aligning the module with the installation guides.
2. Ensure that the module is firmly seated against the back of the chassis.
3. Push in and rotate the attached panel fastener screw clockwise to secure the module to the chassis front.
Install the Fiber Cable
1. Locate or build fiber optic cable with male, two-stranded TX to RX connectors installed at both ends.
2. Connect the fiber cables to the CPSVT26xx-10x media converter as described:
• Connect the male TX cable connector to the female TX port.
• Connect the male RX cable connector to the female RX port.
3. Connect the fiber cables to the other device (another media converter, hub, etc.) as described:
• Connect the male TX cable connector to the female RX port.
• Connect the male RX cable connector to the female TX port.
