INTRODUCTION

The NTI Sun Switch allows a single keyboard, monitor, and mouse to communicate directly with any Sun workstation connected to the switch (up to 32 computers with a single switch, depending on the switch model, or 128 computers when cascaded – see CASCADE section). These computers can be file servers, network managers, etc. The auto-boot circuitry in the NTI Switch allows all computers to boot simultaneously without keyboard error.

Available Options

1. Switch models are available in 60 or 50 Hz, and 110 or 220V.

2. A hard-wired remote control (RMT) is available. This remote comes

standard with a 25 foot cable (REXT-

), but a cable of up to 250 feet can be ordered.

CABLES

Monitor, keyboard and mouse interface CABLES ARE REQUIRED but not supplied. Before beginning installation, refer to installation drawing to insure that you have the proper type and number of cables needed.

1. SUCEXT-xx Connects the video port of the computer to the switch (up to 250 feet)

2. SUKINT-xx-MM OR SUKEXT-xx-MM Connects the keyboard port of the computer to the switch

Optional Materials:

1. SUCEXT-xx-MF Extension cable for the monitor. Use if the video cable is permanently attached to the monitor.

2. SUKINT-xx or SUKEXT-xx Extension cable for the keyboard.

3. REXT-xx-SR Extension cable for the optional wired remote and / or cascading units together.

Where:

xx = length of the cable MM = male-male connector

Cables can be purchase from Network Technologies Inc.

MF = male-female connector

INSTALLAT ION

1. Turn OFF power to all computers that will be connected to the NTI Switch before connecting or disconnecting any cables.

WARNING! Y

OU MAY DAMAGE YOUR COMPUTER IF YOU DO NOT TURN THE POWER

OFF

BEFORE CONNECTING OR DISCONNECTING CABLES

2. If you are cascading units together, configure dip-switches accordingly (see Tables 2-4 on page 4).

3. Connect the monitor to the port labeled MONITOR on the rear of the NTI Switch.

4. Connect the keyboard to the port labeled KEYBD on the rear of the NTI Switch. (The mouse connects to the keyboard.)

5. For each computer: Connect a cable from the Keyboard port of the computer to a Keyboard port of the NTI switch. Note the port’s number. Connect a cable from the Video port of the computer to the Video port of the NTI switch with the same port number as the keyboard. See the illustration below. Make sure the computer is connected to a Keyboard port and a Video port with the same number. Otherwise, you may be typing commands to one computer, but viewing a different computer on the monitor.

6. Plug the NTI Switch into an AC power outlet.

(

)

The dip-switches on the front panel are configurable for several tasks. Switches 1-6 are used for cascading actions (see CASCADING section) and switches 7 & 8 are for keyboard configuration. These keyboard configuration switches come preconfigured with switch 7 in the “ON” position and switch 8 in the “OFF” position. You should not change these settings as this will cause your SUN keyboard to not work. Should the positions of switch 7 or 8 get changed, you will need to power down the entire system (including CPU’s), change the dip-switches back to the required position and then power the system back up. Should you find the need to replace one SUN keyboard with another one, it can be hot swapped without powering down. Refer to Table 1 and the following diagram for instructions on proper keyboard dip-switch configuration.

CASCADING

The SUN switch can be expanded to access up to 128 CPU’s by cascading multiple units together. Up to 8 SUN switches can be connected into another switches CPU ports, as illustrated below. The SUN switch connected to the monitor & keyboard must be configured as the “MASTER” unit (via dip-switc he s). Any switches connected to the “MASTER” must be configured as “SLAVE” units. All SUN switches are fully configurable for this expansion method, the only additional hardware required is a set of keyboard, monitor & RMT extension cables for each “SLAVE UNIT” (see materials).

USING THE NTI SWITCH

The switch can be operated by the front control panel or by keyboard control.

Front Panel Control

1. Pressing any touch switch on the front panel will connect the selected computer to the keyboard, monitor, and mouse.

2. Holding down any front panel touch switch for more than 2 seconds will cause the switch to cycle through 3 extended modes

of operation: SCAN, BROADCAST and COMMAND (described in the

Keyboard Control

panel indicate when these modes are enabled. Release the touch switch when the LED’s show that the mode you desire is

On.

Keyboard Control

In order to control the switch with your keyboard, COMMAND Mode must be enabled. To enable or disable COMMAND Mode from the keyboard:

• Press “CTRL” and “`” (accent key) at the same time.

All 4 status lights on the keyboard will light to indicate that command mode is enabled. When the COMMAND LED is on, the following functions are available:

BROADCAST Mode allows the operator to send keystrokes to all active computers simultaneously. However, BROADCAST Mode has some critical requirements:

1. BROADCAST LED must be OFF when booting any attached computers.

2. BROADCAST LED must be ON and COMMAND LED must be off for keystrokes to reach attached computers.

KEYBOARD UPDATING

Keyboard configuration of each computer is saved in the NTI Switch. For example, if the computer attached to Port 4 had CAPS LOCK and NUM LOCK selected the last time that computer was access e d, then they will auto matically be set when that computer is accessed again.

HOW TO DISABLE OPERATING MODES

The three operating modes of the KEEMUX-Sx SUN KVM switch 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 jumpers 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-Sx.
