Network Technologies KEEMUX-Px operation manual Power Up, Cascading, Limitations

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 light 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). 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.
