NTI KEEMUX Series PS/2 KVM Switch

Power Up

1.Turn the KEEMUX power ON first. The mode LEDs on the KEEMUX should flash twice.

2.Turn the monitor power ON.

3.Turn any or all of the CPUs ON.

FYI: Do not press any port buttons on the front panel until the PORT 1 LED on the front panel illuminates.

CASCADING

The KEEMUX switch can be expanded to access up to 152 CPUs by cascading multiple units together, as illustrated below. The KEEMUX connected to the monitor and keyboard must be configured as the “master unit" (via dip-switches-see page 6). Any switches connected to the master unit must be configured as “slave units". All KEEMUXs are fully configurable for this expansion method. The only additional hardware required is a set of keyboard, monitor, mouse, and RMT extension cables for each slave unit (see Fig. 5 below).

Limitations

a.All the slave units must be the same size.

b.Only 4, 8, or 16-port switches can be used as slave units.

c.Up to 8 slave units may be connected to form a maximum system size of 152 ports (1 x 32 port master

d.Slave units must be added to the master unit in order (slave #1 to master’s port 1, slave #2 to master’s

+8 x 16 port slaves). port 2, etc.).

FYI: Port 1 of the master unit (with a 4-port slave unit connected to it) will function and be controlled as ports 1-4 (1-8 for an 8-port slave, 1-16 for a 16-port, etc.). Port 2 of the master unit (with a second 4-port slave unit connected) will function and be controlled as port numbers 5-8 (9-16 for an 8-port slave, 17-32 for a 16-port slave, etc.). See Fig. 6 on page 6.

e.All units must be powered OFF during configuration and interconnecting.

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.
