KVM switching in an industrial environment
Only about two percent of the gold in Kittila is free metallic gold. The rest is locked inside sulfide minerals. As a result, the refining process is much more complicated. The ore is crushed, ground, floated, oxidated under pressure in an autoclave, and carbon concentrated. It’s then refined electrolytically in a solution. Finally, the gold is melted and poured into bars.
To monitor and control the operation and safety of the ore production, Mr. Jorma Rantanen, IT manager at the plant, set up cameras in the production areas. Operators in a process control room, which looks directly out on the operation, can monitor all aspects of production on multiple screens. "We use two to four monitors with each computer to monitor the production," Mr. Rantanen explained.
Although the control room is a closed-in area, it’s located next to the production area and is not a clean environment. So Mr. Rantanen put the computer CPUs in a safe computer room away from the refining area. To solve the problem of driving the signals between, Mr. Rantanen turned to Black Box.
"The images, along with the keyboard and mouse signals are transmitted approximately 75 feet with the Black Box® ServSwitch™ Wizard Dual-Access, Quad-Head Extenders (ACU5142A). This ServSwitch provides high-end KVM extension with skew compensation over CATx cable. The ServSwitch solved the problem of how to keep the CPUs safe while using the monitors and keyboards in an industrial environment.
In the plant’s computer center, Mr. Rantanen also uses a Black Box ServSelect™ III so two operators can control up to 16 servers simultaneously. The comprehensive features of the ServSelect make control of the servers effective and flexible while eliminating the need for extra equipment and cables, saving a lot of money.
