Chapter 3. Basic Operation

Powering Off and Restarting

If it becomes necessary to power off the KH1508i / KH1516i, or if the switch loses power and needs to be restarted, before starting it back up you must follow these procedures:

1.Shut down all the computers that are attached to it.

Note: You must unplug the power cords of any computers that have the Keyboard Power On function.

2.Wait 10 seconds then power it back on. If you have shut down more than one station, power up the highest station first and work your way down to the lowest one. Wait for each station to display its Station ID on the front panel LED before powering on the next one.

3.After the station(s) is (are) up, power the computers back on.

Port ID Numbering

Each computer on the installation is assigned a unique Port ID. The Port ID is a one or two segment number that is determined by the Stage Level and KVM Port number of the KVM switch that the computer is connected to.

The first segment represents the KVM Port number of the First Stage unit; the second segment represents the KVM Port number of the Second Stage unit.

A computer attached to a First Stage unit has a one segment Port ID (from 1-16) that corresponds to the KVM Port number that it is connected to.

A computer attached to a Second Stage unit has a two segment Port ID:

ŠThe second segment (from 1-16), represents the KVM Port number on the Second Stage unit that the computer is connected to. The first segment (from 1-16) represents the KVM Port number on the First Stage unit that the Second Stage unit links back to.

ŠFor example, a Port ID of 12 - 3 refers to a computer that is connected to KVM Port 3 of a Second Stage unit that links back to KVM Port 12 of the First Stage unit.
