NTI KEEMUX Series PS/2 KVM Switch

HOW TO DISABLE OPERATING MODES

The operating modes of the KEEMUX can be disabled if a user desires to do so. The Command Mode can be disabled which would also disable the Scan and Broadcast Modes, or, the Scan and/or Broadcast Modes can be individually disabled leaving the other features in Command Mode enabled.

To disable these operating modes, the user must get access to the jumper block. This block is located close to the dip- switches on the circuit board the keyboards plug into (called the digital board) inside the KEEMUX. (See Fig. 17.)

If the unit is a rackmount style, the digital board is located directly beneath the cover of the unit, requiring the user to only remove the 10 screws from the cover to get access. With the cover removed, the jumper block will be easy to locate. Follow the instructions under "CONFIGURING THE JUMPER BLOCK" on page 24 to disable the desired mode(s).

If the unit is in a plastic case, the digital board is located on the bottom of the case, requiring the user to partially disassemble the unit to gain access to the jumper block.

For models KEEMUX-Pxin a plastic case:

1.Make sure the KEEMUX is completely disconnected from all CPU components. Be sure to unplug the KEEMUX from the electrical outlet.

2.Remove the two Philips-head screws from the underside of the KEEMUX and set the KEEMUX on a firm and flat surface, bottom down. (See Fig. 18.)

PS/2 KVM specifications

Network Technologies PS/2 KVM switches are essential devices that enable users to control multiple computers from a single set of keyboard, video, and mouse (KVM) peripherals. These devices are particularly advantageous in server rooms, data centers, and environments where space-saving is crucial, as they streamline the management and minimize the clutter of multiple keyboards and monitors.

A key feature of PS/2 KVM switches is their compatibility with the PS/2 interface, which has been a standard for connecting keyboards and mice for many years. This ensures reliable communication and seamless performance when managing various systems. The switch typically supports a wide range of resolutions, allowing users to connect to different video outputs without sacrificing image quality. Most PS/2 KVM setups can handle resolutions up to 1920x1200, making them suitable for high-definition applications.

One of the primary technologies utilized in PS/2 KVM switches is multi-platform support. This allows users to connect and control computers running different operating systems simultaneously, including Windows, Linux, and UNIX. This versatility is essential in environments with varied system requirements and contributes to improved operational efficiency.

In terms of scalability, many PS/2 KVM switches support daisy chaining and cascading, enabling the connection of multiple switches for managing even larger numbers of servers. This is particularly helpful for administrators who need to manage extensive infrastructures without the hassle of additional hardware.

PS/2 KVM switches also come with features such as hotkey switching, which allows users to switch between computers using keyboard shortcuts. This functionality enhances workflow efficiency, as users can quickly access different systems without the need for manual intervention. Additionally, they often include LED indicators that simplify status monitoring, ensuring users are aware of which systems are currently active.

Security is another critical aspect. Many PS/2 KVM switches offer the option to implement password protection and encryption protocols, safeguarding sensitive data during operations.

In summary, Network Technologies PS/2 KVM switches provide a robust and effective solution for managing multiple computers in various settings. Their combination of compatibility, resolution support, scalability, and security features makes them a valuable asset for IT professionals looking to enhance productivity and streamline operations.
