NTI NODEMUX SERIES UNIVERSAL KVM SWITCH

Switch Configuration

Switch Configuration enables the administrator to configure the NODEMUX to be used as a stand alone switch or as one of the switches in a cascaded system. Switch Configuration is also used to setup the communication settings for RS232 communication with a remotely connected terminal through the RS232 port. For the Switch Configuration Mode menu, press <W> from the Administration Mode menu (page 16).

Be careful with this field. If changed to SLAVE, OSD will not work after power cycling.

Configure for Cascading

By default, the NODEMUX is configured to be used by itself, as a "STAND ALONE SWITCH". If the NODEMUX is going to be

used in a cascaded system of switches (see "Cascading" on page 10)		it must be configured for the application. With the
highlighted cursor bar on the top line, press the <	> (up arrow) or <	> (down arrow) to toggle between the following choices:

•MASTER W/ 4-PORT SLAVES

•MASTER W/ 8-PORT SLAVES

•MASTER W/ 16-PORT SLAVES

•SLAVE UNIT

•STAND ALONE SWITCH

Figure 20- Switch configured as a master with one slave attached

A unit configured as a MASTER W/ 4-PORT SLAVES can have up to 8 slaves attached, each with up to 4 ports for CPUs.

A MASTER W/ 8-PORT SLAVES can also have up to 8 slaves attached but those slaves can each have up to 8 CPUs attached. The unit configured as a MASTER W/ 16-PORT SLAVES can have slaves with up to 16 CPUs attached.

With a switch configured as a master, it must also be configured for how many slaves will be connected to it. Move the highlighted cursor bar to "SLAVE COUNT" and press the < > (up arrow) or < > (down arrow) until the number shown reflects the number of slaves being connected to the master.

With the switch configured as a master with one or more slaves, the NODEMUX will automatically sense other switches attached when powered up and list those switches in the Command Mode menu.

If "SLAVE UNIT" is selected, then the Unit number in the configuration must also be selected. No two slaves connected to a master can have the same Unit number. Choose a unit number between 1 and 8 (typically the same number as the port number the slave will be attached to on the master NODEMUX.)
