Introduction

Overview

The Master View CL-1758 KVM Switch is a control unit that allows access to multiple computers from a single keyboard, monitor, and mouse (KVM) console. Before the development of the Master View, the only way to control multiple computer configurations from a single console was through a complex and costly network system. Now, with the Master View CL-1758, you can easily access multiple computers in a cost effective manner.

A single Master View CL-1758 can control up to 8 computers. Since the CL-1758 supports cascading to three levels, in a complete three stage installation, up to 72 Master View CS-1758 models can be cascaded from the CL-1758 to control up to 512 computers - all from the original single console.

The Master View CL-1758 offers a space-saving, streamlined approach to KVM switch technology by integrating a keyboard, LCD monitor, and touchpad in a Slideaway™ housing. The LCD display is built into the cover; the keyboard and touchpad are built into the base. Slide the KVM module section out; flip the cover up; and you are ready to go to work. When finished, flip the cover down and slide the KVM module away.

For further convenience and flexibility, the switch also supports an external keyboard, monitor, and mouse console. Although external consoles often use a PS/2 keyboard and mouse, the CL-1758 supports both PS/2 and USB computers. Depending on the cable you use to link the switch to the computer, you can attach to a computer with PS/2 connectors or USB connectors.

(See Cables, page 4, for more details.)

The Slideaway™ housing is 1U high for easy rack mounting, and because of its modular design, the KVM section can be detached from the switch section. The CL-1758 also features high density 15 pin KVM connectors instead of the usual 25 pin kind. This space-saving innovation provides more reliable and efficient transmission of KVM data, at the same time that it reduces cable clutter.

Your CL-1758 investment is protected by an included Firmware Upgrade Utility. You can stay current with the latest functionality improvements by downloading firmware update files from our website as they become available, and using the utility to quickly and conveniently perform the upgrade.

CL-1758 User Manual

Access to any computer connected to the installation is easily accomplished either through a powerful, mouse driven, OSD (On Screen Display) menu system, or by entering Hotkey combinations from the keyboard. A convenient Auto Scan feature also permits automatic scanning and monitoring of the activities of all computers running on the installation one by one.

Setup is fast and easy; simply plug cables into their appropriate ports. There is no software to configure, no installation routines, and no incompatibility problems. Since the CL-1758 intercepts keyboard input directly, it works on multiple operating platforms (PC compatible, Mac*, Sun*, etc.).

There is no better way to save time and money than with a CL-1758 installation. Since a single console manages all of the computers, the CL-1758 setup: (1) eliminates the expense of having to purchase a separate keyboard, monitor, and mouse for each computer; (2) saves all the space those extra components would take up; (3) saves on energy costs; and (4) eliminates the inconvenience and wasted effort involved in constantly moving from one computer to another.

* Mac and Sun computers must use the USB cable connection (see p. 4).

Note: It takes two people to mount the switch: one to hold it in place; the other to screw it in.

Optional mounting kits - including single person Easy Installation kits - are available with a separate purchase. See Optional Rack Mounting, page 67 for optional rack mounting details.

Chapter 2. Hardware Setup

To rack mount the switch, do the following:

1.While one person positions the switch in the rack and holds it in place, the second person - using the screws provided with the rack mounting kit - loosely screws the front brackets to the rack.

2.While the first person still holds the switch in place, the second person slides the L brackets into the switch's side mounting brackets, from the rear until the bracket flanges contact the rack, then - using the screws provided with the rack mounting kit - screws the L brackets to the rack.

3. After the L brackets have been secured, tighten the front bracket screws.

Note: 1. Cage nuts are provided for racks that are not prethreaded.

2.Allow at least 5.1 cm on each side for proper ventilation, and at least 12.7 cm at the back for the power cord and cable clearance.

Two Stage Installation

To control even more computers, up to eight additional Master View CS-1758 units can be cascaded from the KVM ports of the First Stage unit. The cascaded Master Views that connect back to the First Stage unit are considered Second Stage units. As many as 64 computers can be controlled in a complete two stage installation. A table showing the relation between the number of computers and the number of units needed to control them is provided on page 64.

To set up a two stage installation, refer to the Two Stage Installation diagram on the next page as you do the following:

1.Make sure that power to all the devices you will be connecting up, including all preexisting devices on the installation, have been turned off.

2.Use a USB KVM cable set (see Cables, page 4), to connect any available KVM Port on the First Stage unit to the Console ports of the Second Stage unit.

Note: Plug the USB connector into the USB port next to the Console SPHD port (they are both marked with a similar icon to remind you of the correct USB port).

3.Using a KVM cable set (see Cables, page 4), plug the custom SPHD connector into any available KVM Port on the switch.

Note: The CL-1758 does not support the audio features of audio enabled KVM switches.

Three Stage Installation

The procedures for setting up a three stage installation are essentially the same as for a two stage installation. With a three stage setup, as many as 512 computers can be controlled in a complete installation. A table showing the relation between the number of computers and the number of switches needed to control them is provided on page 64.

Note: Switches cannot be cascaded beyond the third level.

To set up a three stage installation, refer to the Three Stage Installation diagram on the next page. Once you have finished cabling up (see Two Stage Installation for details, if necessary), power up according to the following sequence:

1.For each Third Stage unit, plug the power adapter cable into the switch's Power Jack; plug the power adapter into an AC source.

2.For each Second Stage unit, plug the power adapter cable into the switch's Power Jack; plug the power adapter into an AC source.

3.Power On the First Stage unit.

4.Turn on the power to all the computers.

Note: The Power On sequence requires that all Third Stage units be powered on first. After they are all on, the Second Stage units must be powered on next. After all the Second Stage units are on, the First Stage unit must be powered on. Only after all the switches have been powered on in this sequence, can the computers be powered on.
