Different KVM Devices Explained: Boosting Productivity in Computing

KVM devices, which include switches and extenders, are important tools for enhancing computer management efficiency. They simplify office space, support various video and USB devices, and enable remote control of computers.

What Are the KVM Devices?

KVM devices, in the context of computer hardware, often refer to KVM switches and KVM extenders:

KVM switches: A KVM (Keyboard, Video Monitor, Mouse) switch allows a user to control multiple computers from a single set of peripherals. For example, if you have two or more computers, you can use a single keyboard, mouse, and monitor to switch back and forth between the systems. This is especially useful in server rooms or data centers where multiple servers can be controlled by one console, saving space and reducing hardware costs.

KVM Extenders: A KVM extender allows the keyboard, video monitor, and mouse to be located at a distance from the computer itself. This can be useful in situations where you need to control a computer that's in a secure, clean, or distant location relative to the user. The extender transmits the KVM signals over Cat5/6 cable, fiber optic, or even wirelessly in some cases, allowing the peripherals to be used as if they were directly connected to the computer, even if it's located hundreds of feet away or in another room.

Both devices are critical in varying scenarios where direct access to multiple computers or remote access to a single computer is required. These solutions can also come with features such as support for different types of video connections (HDMI, DVI, VGA, DisplayPort), USB peripherals, audio transmission, and even support for virtual media and smart card readers.

Different Types of KVM Switches

Desktop KVM Switches

Desktop KVM switches are compact devices that enable users to control multiple computers from a single keyboard, monitor, and mouse. Ideal for small office or home office setups, they can handle between 2 to 8 computer connections, streamline the workspace, and switch easily between systems with the press of a button or a keyboard shortcut. These switches support various video standards and often include additional features like USB sharing and audio support, making them convenient and versatile tools for managing multiple PCs in close proximity.

Rack-Mount KVM Switches

Rack-mount KVM switches provide centralized control of multiple servers in a space-efficient manner. By taking up minimal rack space, typically only 1U, these switches allow a single console to manage a substantial number of servers, reducing clutter and improving organization within data centers and server rooms. The capability to cascade multiple units, such as connecting 8 USB KVM switches, further increases this efficiency, enabling the control of up to 128 servers or PCs from a single set of peripherals (keyboard, mouse, and monitor), which is ideal for scaling operations without the need for additional space or equipment. Advanced models may also offer remote access for convenient server management from any location.

IP Remote Access KVM Switches

IP Remote Access KVM Switches allow administrators to remotely manage servers via a network connection. Administrators can monitor and control servers in real-time from anywhere with an internet connection, using a standard web browser or client software. This offers significant flexibility and convenience, particularly for troubleshooting, maintenance, or updates. KVM switches without built-in IP remote access can be upgraded with an optional IP Remote Access Unit to expand capabilities.

In addition to this, FS also provides LCD/LED KVM Switches as well as KVM Terminal Controllers.

LCD/LED KVM Switches are devices integrated with an LCD or LED screen as well as a keyboard and touchpad, which can control multiple computers, save rack space, and reduce clutter.

KVM Terminal Controllers are rack-mounted consoles that come with a screen and input devices, used for direct management of servers. Some have built-in KVM switching capabilities, while others must be connected to a separate KVM switch.

Both types of equipment are primarily used in data centers and server rooms to conserve space and improve efficiency.

Common Problems with KVM Switches

Compatibility Issues Between Different Operating Systems?

Generally, KVM switches with standard USB keyboard and mouse interfaces should work across most operating systems. If there are special requirements between operating systems, consult the KVM switch's user manual or contact the manufacturer for support.

How to Configure the KVM Switch to Support Different Video Resolutions and Refresh Rates?

Many KVM switches can automatically detect and adapt to the resolution and refresh rate of connected monitors. In some cases, you might need to manually configure your computer's display settings to ensure that the KVM switch can properly handle the signal.

After-Sales Service and Technical Support?

Understanding whether a manufacturer provides comprehensive after-sales service and technical support is crucial when purchasing a KVM switch. Checking the manufacturer's customer service record and warranty policy can help ensure timely assistance in case of an issue.

Conclusion

When selecting KVM devices, considering operating system compatibility, resolution support, and customer service is crucial. Whether in a home office or a data center, the right KVM solution can help users effectively manage their computer networks.
