Configurations KVM switch modules are available with four, eight (Models 521796, 523561 and 523578) and 16 ports (Model 521871) with various interfaces. In applications that require a larger number of computers, the KVM switch modules can be cascaded in a master/slave configuration. NOTE: Throughout this user manual, “master” refers to the KVM switch module that connects directly to the console drawer; “slave” refers to a KVM switch module that has its console port connected to a master’s “

2. INSTALLATION Device Connection Standard Models (Model 521871): Determine the port number of each computer. For computers using a PS/2 mouse, connect the computer’s mouse and keyboard cables to the connectors marked with a mouse and keyboard, respectively, as shown. Repeat this step for PC-1 through PC-8. For computers using a serial mouse, connect the DB9-to-mini-DIN6 adapter (included with the switch) to the computer mouse port, then use PS/2 cables to connect the mouse to th

To a PS/2 computer: Connect a PS/2 “Y” adapter, which comes with the unit, to the PS/2 port on the PC side, then use two mini-DIN6 male-to-male cables for the keyboard and mouse, as shown below. There are two mini-DIN6 female connectors on the PS/2 “Y” adapter marked for the keyboard and mouse. NOTE: Be sure not to swap the connections. To a laptop computer: In most cases, all you need is one PS/2 male-to-male cable connecting the KVM switch module and your laptop, as shown below; the “Y”

A Module as a Slave or a Stand-Alone KVM Switch A slave KVM switch module can be mounted to the inside of the rear uprights of a rack cabinet using the rear brackets (which come with all units except IKM001), with computer connectors facing to the rear, as well. NOTE: The connectors (keyboard and mouse) at the local port on the rear of the KVM module are not applicable when the module is connected to the TFT LCD drawer by the CEN36 connector. When the CEN36 connector is not connected t

and indicates the currently selected computer or operating status. A triangle mark (4) to the right of a name indicates the port is cascaded to a slave. The number to the left of the triangle mark shows the number of ports the slave has; e.g., 84 for an 8-port switch. The Enter key brings you one level down, and another screen pops up listing the names of the computers on that slave. The name of the slave will be shown at the upper-right corner of the OSD menu. It is useful to group compute

To select a computer by hotkey command, you need to know its port number, which is determined by the KVM switch module connection. For a computer connected to a master, its port is represented by the PC port label (1 – 8 or A – H). For a computer connected to a slave, two characters represent its port. The first character is the port number of the master unit (1 – 8); the second is the port number of the slave (1 – 8 or A – H). Note that only a master’s PC-1 through PC-8 ports can be conne

NOTE: The master must have at least as many PC-x ports as the slave; e.g., if an IKM108D is the master, another IKM108D can be a slave, but not an IKM116D (see the reference on Page 5). The ports PC-1 through PC-8 can be connected to either a computer or a slave’s local (or console) port, as shown at right. The ports PC-A through PC-H can only be connected to computers. NOTE: Only a master’s PS/2 PC ports (not USB ports) can be connected to a slave’s local (or console) port for casc

5. MULTI-ACCESS MODEL A multi-access console KVM switch (IKM2108D, IKM2116D) features a pair of console ports, facilitating access to multiple computers from both a local and a remote location. An example of the practicality of this feature is the ability to access all computers in a configuration from inside a server room when you need to physically access the computers — as when performing a software upgrade — while being able to manage the computers outside the server room for daily use.

6. SUN/MAC KEYBOARD MAPPING IGM108D and IGM116D models emulate a Sun keyboard and mouse when a computer is marked with a Sun in the OSD menu by function key F5. A Sun keyboard has more keys than a standard PS/2 keyboard. These extra keys are simulated by pressing the right Control key followed by one of the function keys on the PS/2 keyboard. For example, press the right Control key, then press function key F7 to activate Open for a Sun computer. From PS/2 Map to Sun Map to Mac keyboa
