36 SERVSWITCH™ BRAND FIBER KVM EXTENDERS 5.4 Running Fiber Cable Between the Local and Remote Modules You’ll need breakout-style fiberoptic cabling with at least five fibers to connect the Extender’s Local Module to its Remote Module. What type of cable(s) you use will depend on where you’re going to run them: • Indoors: Use bulk pretermi[...]

37 CHAPTER 5: Installation CAUTION! One of the most common errors in cabling the Extender is to attach fiber strands “1” and “2” to the Remote Module backwards (strand 1 to port 2, strand 2 to port 1). Notice that while the fiber ports on the Local Module are arranged in left-to-right order as “R,” “G,” “B,” “1,” and “2,?[...]

35 CHAPTER 5: Installation 3. ACS235A: Run a PS/2 mouse-extension cable from the switch’s PS/2 CPU- mouse port to the 6-pin mini-DIN female mouse port on the Remote Module (the port labeled with the picture of a mouse). (The switch’s CPU-mouse port must be PS/2 type.) 4A. ACS235A: If the switch has an input-only CPU-parallel port that is pinned[...]

36 SERVSWITCH™ BRAND FIBER KVM EXTENDERS 5.4 Running Fiber Cable Between the Local and Remote Modules You’ll need breakout-style fiberoptic cabling with at least five fibers to connect the Extender’s Local Module to its Remote Module. What type of cable(s) you use will depend on where you’re going to run them: • Indoors: Use bulk pretermi[...]

37 CHAPTER 5: Installation CAUTION! One of the most common errors in cabling the Extender is to attach fiber strands “1” and “2” to the Remote Module backwards (strand 1 to port 2, strand 2 to port 1). Notice that while the fiber ports on the Local Module are arranged in left-to-right order as “R,” “G,” “B,” “1,” and “2,?[...]

38 SERVSWITCH™ BRAND FIBER KVM EXTENDERS 6. Operation The ServSwitch™ Brand Fiber KVM Extender Modules should begin operating as soon as they (and all attached devices) are plugged in; the green and red Power LEDs on the units’ rear panels should light. (If either LED on a Module fails to light, that Module has had an internal failure; contac[...]

39 CHAPTER 6: Operation Three (AGC enabled only): Low blue. Even applying max AGC, the unit can’t equalize the color signals, of which blue is at the lowest level. There’s trouble with the blue transmit diode, fiber, or receive diode. F: Contrast is turned up too high at the Remote Module for AGC to work properly. Turn the contrast down using t[...]
