Cable Length Considerations
Note: KVM server modules are also referred to as KVM adapter cables.
• Do not exceed 66 feet (20m) between the switch and the local monitor.
• To support a resolution of 1280x1024, the recommended maximum distance between the KVM
switch and the KVM server module is 164 feet (50m).
Hot Plugging
Components can be removed and added to the installation by unplugging and re-plugging their cables
without the need to shut down.
Change KVM Switch positions by unplugging from the old parent KVM switch and plugging into a new
parent KVM switch. Afterwards, in order for the OSD menus to correspond to the change, reset the
OSD. See “Reset Station IDs” on page 19.
Hot plugging KVM ports. After switching KVM ports, in order for the OSD menus to correspond to
the change, you may need to reconfigure the OSD information for the new port information. The settings
of the port name, operating system, and keyboard language will be restored to the KVM switch from any
previously used adapter cables after they are plugged in. See “F3: SET” on page 16 and see “F4: ADM”
on page 18 for port setting selections.
Note: 1. If a computer's operating system doesn't support hot plugging, this function may not
work properly.
2. Empty ports that previously were connected to an server module will retain their prior
configuration data.
Hot plugging console ports. The keyboard, monitor, and mouse can be hot plugged. When hot
plugging the mouse, however, be aware of the following:
• If you unplug the mouse (to reset the mouse, for example), you must use the same mouse when
you plug back in.
• If you plug in a different mouse, all the KVM switches and all the computers on the installation
must be shut down for 10 seconds, then restarted (see “Powering Off and Restarting” on page 12).
• Some older operating systems may not support hot-plugging.
Note: If, after hot plugging (or at any other time), there is no response to keyboard
and/or mouse input, perform a keyboard and mouse reset by pressing in the Reset
switch. See “Reset Switch” on page 5.
