Chapter 1. Introduction Overview The KH88 KVM Switch is a control unit th at allo ws access to multip le computers from a single console (keyboard, monitor, and mouse). Before the development of KVM switching, the only way to control multiple computer configurations from a single console was through a complex and costly network.
Features M Controls 8 computers from a single console M Cascadable to three levels from any port - control up to 512 computers from a single console M Administrator/User password authorization for enh.
Hardware Requirements Console M A VGA, SVGA, or Multisync monitor capable of the highest resolution that you will be using on any computer in the installation. M A PS/2 style mouse M A PS/2 style keyboard Computer The following equip m en t mus t be in stalled on each co mputer : M A VGA, SVGA or Multisync card.
Cables Use of substandard cables may damage the connected devices or degrade overall performance. For optimum signal integrity and to simplify the layout, we strongly recommend that you use the following high quality CS Custom Cable sets: Cable Purpose Part Number Connect to Computer 2L-1001P/C (1.
Chapter 2. Hardware Setup Front Panel 1. Port LEDs The upper Port LEDs are the On Line LEDs; the lower ones are the Selected Port LEDs: w The On Line LEDs light GREEN to indicate that the computer attached to the corresponding port is up and running.
3. Reset w Use a thin object (such as the end of a paper clip, or a ballpoint pen), to press this recessed switch in to initiate a warm reset. w If the switch is kept in for longer than three seconds, a cold reset takes place. 4. Power LED w Lights steadily to in dicate th at th e unit is receiv ing power .

Installation Before you Begin Single Station Installation In a Single Stage installation, there are no additional KH88’s cascaded down from the first unit. To set up a single stage installation refer to the diagram below (the numbers in the diagram correspond with the numbers of the instruction steps), and do the following: 1.
Two Stage Installation To control even more computers, up to eight additional KH88 units can be cascaded from the CP U ports of th e F ir s t S tag e uni t. T h e cas cad ed KH88s th at connect back to the Fir s t Stage unit ar e co nsid er ed Seco nd Stag e units .
6. Power on the Second Stage unit(s), the n power on the First Stage unit. 7. Turn on the power to all the computers. Note: The Power On sequence requires that all Second Stage units be powered on first. After all the Second Stage units have been powered on, the First Stage unit must be powered on next.
Three Stage Installation The procedures for setting up a three stage installation are essentially the same as for a two stage installation. With a three stage setup, as many as 512 computers can be controlled in a complete installation.

Setup Considerations Hot Plugging The KH88 supports hot plugging. Components can be removed and added back into the installation by unplugging and replugging their cables from their respective ports without the need to shut the switch down.
Powering Off and Restarting If it becomes necessary to Power Off one of th e KH88 units , bef ore startin g it back up you must do the following: 1. Shut down all the computers that are attached to the unit. If there are stations cascaded down from it, all the cascaded stations and the computers attached to them must be shut down, as well.
Port ID Numbering Each CPU Port on a KH88 installation is assigned a unique Port ID . You can directly access any computer on any level of the installation by specifying the Port ID of the CPU port that the computer is co nnected to - eith er with th e Hotkey port selection method, or with the OSD.
Port Selection The KH88 provides three methods to obtain in stant acces s to an y co mputer on your installation: Manual, OSD, and Hotkey. Manual: Simply press the appropriate Port Selection Switch on the unit’s front panel. After you press the switch, the Selected LED lights to indicate that the port has the KVM focus.
