6.3 Finishing Your Installation

To finish installing your Micro Extender system after attaching devices to it as described in Section 6.2, take these steps:

1.Attach the output cord of the Remote Unit’s power supply to the Unit’s power jack. Then plug the IEC 320 end of the power supply’s input cord into the IEC 320 inlet on the power supply’s transformer. Finally, plug the other end of the input cord into a utility (mains) power outlet. The Remote Unit should power up immediately; it has no ON/OFF switch. (If the Remote Unit is in the location you want it to be, you can leave it plugged in and powered up more or less indefinitely.)

CAUTION!

If you ever need to replace the power supply of the Remote Unit, the replacement power supply must have identical output characteristics (see the “Power” specification in Chapter 2). Using a power supply with different output—even if it’s “almost the same”—could damage your equipment.

2.Power ON the monitor or KVM switch attached to the Remote Unit. Dual- Access systems: Power ON any monitor or switch attached to the Local Unit’s user ports.

3.Interconnect the Local and Remote Units by running CAT5 cable between their right-side-mounted modular jacks (the ones labeled “Interconnect”). Refer to the guidelines for this cable in Section 4.2.5.

4.Power ON the PC CPU or KVM switch attached to the Local Unit’s CPU port. If the CPU or switch provides enough DC voltage on its keyboard port/leads, the Local Unit will begin operating immediately; like the Remote Unit, it has no ON/OFF switch. The LED on the Local Unit’s right-side panel should light steadily (to show that it’s powered). Once the Local Unit has detected both (a) the presence of the Remote Unit and (b) initial keyboard commands from the PC, this LED should start flashing regularly (to show that the link between the Units is working).

If this LED doesn’t light, check the CPU or switch (is it actually on?) and the KVM-extension cables (are they securely connected to the proper ports at both ends?). If this LED lights but remains steadily lit, even after more than a minute (it might take some older CPUs that long to boot to the point at which they attempt to communicate with the keyboard), check the CAT5 cable between the Units (is it secure at both ends? is it intact, or is it broken?).
