Overview

The CL5708 / CL5716 Slideaway™ LCD KVMP Switch is an integrated LCD console and keyboard, video, and mouse (KVM) switch that offers secure access to 8 or 16 attached computers and mounts in only 1U of rack space. It features an independently retractable 17" LCD monitor and keyboard with built-in touchpad. An extra console port is provided on the rear panel to manage the LCD KVM switch from an external console (monitor, keyboard, and mouse) up to 20 meters away. For added convenience it also supports an external USB mouse.

The CL5708 / CL5716 supports both PS/2 and USB keyboards and mice for the connected computers, and the CL5708 / CL5716 supports USB peripheral devices to be used with the attached computers. A single CL5708 / CL5716 can control up to 8 or 16 computers. As many as 31 additional compatible KVM switches can be daisy chained together, so that up to 256 or 512 computers can all be controlled from a single keyboard, monitor, and mouse console. (See the Appendix for a list of compatible ATEN switches.)

The CL5708 / CL5716 is built on a modular design. The KVM section can be detached from the switch section for convenient maintenance and repair. A special feature of the CL5708 / CL5716 D and E models is their use of DC power instead of the AC power used by most switch products.

There are four models in the series as outlined in the following table:

Model LCD	Panel KVM	Ports Power
CL5708D 17"	8 DC
CL5716D 17"	16 DC
CL5708M 17"	8 AC
CL5716M 17"	16 AC

Your CL5708 / CL5716 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.

Setup is fast and easy: plugging cables into their appropriate ports is all that is entailed. Because the CL5708 / CL5716 intercepts keyboard input directly, there is no software to configure, no need to get involved in complex installation routines, nor any need to be concerned with incompatibility problems. Access to any computer connected to the installation is easily accomplished either by entering hotkey combinations from the keyboard, or by means of a powerful, mouse driven, OSD (on-screen display) menu system. A convenient Auto Scan feature also permits automatic scanning and monitoring of the activities of all computers running on the installation one by one.

There is no better way to save time and money than with a CL5708 / CL5716 installation. By using the CL5708 / CL5716 with its sliding LCD console to manage your installation, you: eliminate the expense of having to purchase a separate keyboard, monitor, and mouse for each computer; save all the space those extra components would take up; save the space that a keyboard, monitor, and mouse would take with a standard KVM switch; save on energy costs; and eliminate the inconvenience and wasted effort involved in constantly moving from one computer to another.

2. Release the catches; pull the module slightly toward you; then push it all the way in.

Note: The reason for the two step procedure is to minimize the chances of you pinching your fingers when sliding the module in.

Operating Precautions

The maximum load bearing capacity of the keyboard module is 30kg. Failure to heed the information below can result in damage to the keyboard module.

	Right!Rest your hands and arms lightly on the keyboard module as you work.
	Wrong!♦ DO NOT lean your body weight on the keyboard module.♦ DO NOT place heavy objects on the keyboard module.

Powering Off and Restarting

If it becomes necessary to power off the CL5708 / CL5716, do the following before restarting it:

1. Shut down all the computers that are attached to the CL5708 / CL5716.

Note: Unplug the power cords of any computers that have the Keyboard Power On function. Otherwise, the CL5708 / CL5716 will still receive power from the computers.

1. Unplug the CL5708 / CL5716 from its power source.
2. Wait 10 seconds, then plug the CL5708 / CL5716 back in.
3. After the CL5708 / CL5716 has started and ascertained its station ID, power on the computers.

Note: If you have shut down more than one station, power up the highest station first and work your way down to the lowest one.

LCD OSD Configuration

The LCD Buttons

The LCD OSD allows you to set up and configure the LCD display. Four buttons are used to perform the configuration, as described in the table, below:

Button Function
MENU	When you have not entered the LCD OSD Menu function, pressing this button invokes the Menu function, and brings up the Main Menu.When you have entered the LCD OSD Menu function, and have reached a setting choice with the navigation buttons, pressing this button brings up its adjustment screen.
▶|▲	When navigating through the menus, this button moves you Right or Up. When making an adjustment, it increases the value.
◀|▼	When navigating through the menus, this button moves you Left or Down. When making an adjustment, it decreases the value.
EXIT	When you have not entered the LCD OSD Menu function, pressing this button performs an auto adjustment. An auto adjustment automatically configures all the settings for the LCD panel to what the OSD considers their optimum values to be.When you have entered the LCD OSD Menu function, pressing this button exits the current menu and returns you to the previous menu. Use it to leave an adjustment menu when you are satisfied with the adjustment you made.When you are at the Main Menu, pressing this button exits the LCD OSD.

LCD Adjustment Settings

An explanation of the LCD OSD adjustment settings is given in the table below:

Setting Explanation
Brightness Adjusts the background black level of the screen image.
Contrast Adjusts the foreground white level of the screen image.
Phase If pixel jitter or horizontal line noise is visible on the display, your LCD may have the wrong phase setting. Adjust the phase setting to eliminate these problems.
Clock If vertical banding is visible on the display, your LCD may have the wrong clock setting. Adjust the clock setting to eliminate vertical banding.
H-Position Positions the display area on the LCD panel horizontally (moves the display area left or right).
V-Position Positions the display area on the LCD panel vertically (moves the display area up or down).
Color Temperature Adjusts the color quality of the display. You can adjust the warmth value, color balance, etc. The Adjust Color selection has a further submenu that lets you fine tune the RGB values.
Language Selects the language that the OSD displays its menus in.
OSD Duration Lets you set the amount of time the OSD displays on the screen. If there is no input for the amount of time you choose, the OSD display turns off.
Reset Resets the adjustments on all menus and submenus to their factory default settings.

Note: As an alternative to manually adjusting the LCD settings, you can have the LCD auto-adjusted for optimum display by pressing the Exit button. See EXIT, page 25

Hot Plugging

The CL5708 / CL5716 supports hot plugging - components can be removed and added back into the installation by unplugging their cables from the ports without the need to shut the unit down. In order for hot plugging to work properly, however, the procedures described below must be followed:

Changing Station Positions

You can change a station's position by simply disconnecting it from its master and reconnecting it to another switch in the chain. In order for the OSD menus to correspond to the change, the station IDs must be reset in the OSD. See RESET STATION IDS, page 41, for details.

Hot Plugging KVM Ports

You can add or remove computers by plugging/unplugging them into/from a switch's KVM ports. In order for the OSD menus to correspond to the change, however, you must manually reconfigure the OSD to reflect the new Port information. See F3: SET, page 36, and F4: ADM, page 38, for details.

Note: If the computer's Operating System does not support hot plugging, this function may not work properly.

Hot Plugging External Console Ports

The external keyboard, monitor, mouse and front panel mouse connections can all be hot plugged. When hot plugging a mouse:

• You may unplug and replug the mouse (to reset the mouse, for example), as long as you use the same mouse.
• If you plug in a different mouse, all the stations and all the computers on the installation must be shut down for 10 seconds, then restarted following the power up sequence described under Step 5 on page 19.

Port Selection

The CL5708 / CL5716 provides three port selection methods to access the computers on the installation: Manual, an OSD (on-screen display) menu system, and Hotkeys. Manual port switching is discussed below. See Chapter 4, OSD Operation and Chapter 5, Keyboard Port Operation for more information.

Manual Port Switching

Use the UP and DOWN Port ID / Station ID selection buttons located on the keyboard module (page 8) to switch KVM focus to any port on the installation. Continually pressing any button cycles through the list of available ports/stations.

Port ID Numbering

Each KVM port on the installation is assigned a unique Port ID. The Port ID is made up of two parts: a Station Number, and a Port Number:

• The Station Number is a two digit number of the switch's position in the daisy chain sequence. This number is displayed on the front panel station ID LED.
• The Port Number is a two digit number of the port on the CL5708 / CL5716 station that a computer is connected to. This number is displayed on the front panel port ID LED.
• When keying in a Port ID number, the station number precedes the port number.
• Station and port numbers from 1–9 are padded with a preceding zero, so they become 01–09.

For example, a computer attached to Port 6 of Station 12 would have a Port ID of: 12-06.

USB Peripheral Devices

The front panel USB port is available to connect a USB peripheral device (flash drive, CD-ROM drive, printer, etc.) to the CL5708 / CL5716. Any computer connected to the CL5708 / CL5716 can access the USB peripheral on a one-at-a-time basis. The peripheral device is available to computers connected to the CL5708 / CL5716 on the same level only, and is not available to computers connected to daisy chained switches.

The USB peripheral device is automatically detected on target computers when switching ports on the CL5708 / CL5716. For example, when switching from a computer connected to port 1 to a computer connected to port 2, the peripheral device automatically disconnects from the computer on port 1 and connects to the computer on port 2.

OSD Overview

The OSD (on-screen display) is a mouse and keyboard enabled, menu driven method to handle computer control and switching operations. All procedures start from the OSD main screen.

OSD Login

The OSD incorporates a two level (administrator / user) password system. Before the OSD main screen displays, a login screen appears requiring a password. If this is the first time that the OSD is used, or if the password function has not been set, simply press [Enter]. The OSD main screen displays in administrator mode. In this mode, you have administrator privileges, with access to all administrator and user functions, and can set up operations (including password authorization) as you like. However, if the password function has been set, you must provide an appropriate administrator/user password in order to access the OSD.

OSD Hotkey

You can display the OSD on the LCD or an external console monitor while also viewing the display of any port on the CL5708 / CL5716 by pressing the [Scroll Lock] key twice.

Note: You can optionally change the OSD hotkey to the Ctrl key, in which case you would press [Ctrl] twice (see OSD Hotkey, page 36). With this method, you must press the same [Ctrl] key.

OSD Main Screen

When you invoke the OSD, a screen similar to the one below appears:

Note: 1. The diagram depicts the administrator's main screen. The user main screen does not show the F4 and F6 functions, since these are reserved for the administrator and can't be accessed by users.
2. The OSD always starts in list view, with the highlight bar at the same position it was in the last time it was closed.
3. Only the ports that have been set accessible by the administrator for the current logged in user are visible (see SET ACCESSIBLE PORTS, page 39, for details).
4. If the port list is collapsed, click on a switch number, or move the highlight bar to it then press the right arrow key to expand the list. Similarly, to collapse a switch's port list, click on the switch number, or move the highlight bar to it then press the left arrow key to collapse the list.

OSD Main Screen Headings

The table below describes the OSD Main Screen headings.

Heading Description
SN--PN This	column lists the port ID numbers (station number - port number) for all the KVM ports on the installation. The simplest method to access a particular computer is move the highlight bar to it, then press [Enter].
QV If a port	has selected for quick view scanning (see Set Quick View Ports, page 40), an arrowhead displays in this column.
	The computers that are powered on and are online have a sun symbol in this column.
NAME	If a port has been given a name (see Edit Port Names, page 40), its name appears in this column.

• While you are in Auto Scan mode, you can pause the scanning in order to keep the focus on a particular computer either by pressing [P], or with a left-click of the mouse. See Invoking Auto Scan, page 48, for details.
• To exit Auto Scan mode, press the [Spacebar] or [Esc].

F8: LOUT

Clicking the F8 field, or pressing [F8] logs you out of OSD control of the computers, and blanks the console screen. This is different from simply pressing [Esc] when you are at the main screen to deactivate the OSD. With this function you must log in all over again to regain access to the OSD, whereas with [Esc], all you have to do to reenter the OSD is tap the OSD hotkey.

Keyboard Port Operation

Hotkey Port Control

Hotkey port control allows you to provide KVM focus to a particular computer directly from the keyboard. The CL5708 / CL5716 provides the following hotkey port control features:

• Selecting the Active Port
• Auto Scan Mode Switching
• Skip Mode Switching
  ◆ Computer Keyboard / Mouse Reset

The following settings can also be controlled in Hotkey mode:

Setting the Beeper
Setting the Quick Hotkey
Setting the OSD Hotkey
Setting the Port Operating System
♦ Restoring the OSD Default Values

Invoke Hotkey Mode

All hotkey operations begin by invoking Hotkey mode. ¹ There are two possible keystroke sequences used to invoke Hotkey mode, though only one can be operational at any given time:

Number Lock and Minus Keys

1. Hold down the Num Lock key;
2. Press and release the minus key;
3. Release the Num Lock key:

[Num Lock] + [-] 

Control and F12 Keys

1. Hold down the Ctrl key;
2. Press and release the F12 key;
3. Release the Ctrl key:

[Ctrl] + [F12] 

When Hotkey mode is active:

A command line appears on the monitor screen. The command line prompt is the word Hotkey: in white text on a blue background, and displays the subsequent hotkey information that you key in.
- Ordinary keyboard and mouse functions are suspended – only hotkey compliant keystrokes (described in the sections that follow), can be input.

Pressing [Esc] exits Hotkey mode.

Select the Active Port

Each KVM port is assigned a port ID (see Port ID Numbering, page 27). You can directly access any computer on the installation with a hotkey combination that specifies the port ID of the KVM port that a computer is connected to. To access a computer using hotkeys:

1. Invoke hotkey mode with the [Num\ Lock] + [-] or [Ctrl] + [F12] combination.
2. Key in the port ID.

The port ID numbers display on the command line as you key them in. If you make a mistake, use [Backspace] to erase the wrong number.

1. Press [Enter].

After you press [Enter], the KVM focus switches to the designated computer and you automatically exit hotkey mode.

Note: In hotkey mode, KVM focus will not switch to a port if an invalid switch or port number is entered. The hotkey command line will continue to display on the screen until you enter a valid switch and port number combination, or exit hotkey mode.

Auto Scan Mode

Auto Scan automatically switches, at regular intervals, among all the KVM ports that have been set as accessible under Scan-Skip Mode, so that their activity can be monitored automatically. See Scan-Skip Mode on page 37 for more information.

Invoking Auto Scan:

To start Auto Scan, key in the following Hotkey combination:

1. Invoke hotkey mode with the [Num Lock] + [-] or [Ctrl] + [F12] combination.

2. Press [A]. After you press A, then [Enter], you automatically exit hotkey mode, and enter Auto Scan mode.

- While you are in Auto Scan mode, you can pause the scanning in order to keep the focus on a particular computer either by pressing P or with a left click of the mouse. During the time that auto-scanning is paused, the command line displays: Auto Scan: Paused.

Pausing when you want to keep the focus on a particular computer is more convenient than exiting Auto Scan mode because when you resume scanning, you start from where you left off. If, on the other hand, you exited and restarted, scanning would start over from the very first computer on the installation.

To resume Auto Scanning, press any key or left-click. Scanning continues from where it left off.

- While Auto Scan mode is in effect, ordinary keyboard and mouse functions are suspended – only Auto Scan mode compliant keystrokes and mouse clicks can be input. You must exit Auto Scan mode in order to regain normal control of the console.

1. To exit Auto Scan mode press [Esc] or [Spacebar]. Auto-scanning stops when you exit Auto Scan mode.

Skip Mode

This feature allows you to switch between computers in order to monitor them manually. You can dwell on a particular port for as long as you like – as opposed to auto-scanning, which automatically switches after a fixed interval. To invoke Skip mode, key in the following hotkey combination:

The Firmware Upgrade Utility

Introduction

The purpose of the Windows-based firmware upgrade utility is to provide an automated process for upgrading the CL5708 / CL5716 and compatible adapter cable firmware. The program comes as part of a firmware upgrade package that is specific for each device.

As new firmware versions become available, new firmware upgrade packages are posted on our website. Check the website regularly to find the latest information and packages.

Downloading the Firmware Upgrade Package

To download the firmware upgrade package:

1. From a computer that is not part of your KVM installation go to our website and choose the model name that relates to your device. A list of available firmware upgrade packages appears.
2. Choose the firmware upgrade package that you wish to install (usually the most recent) and download it to your computer.

Preparation

To prepare for the firmware upgrade, do the following:

1. Use the Firmware Upgrade Cable (provided with this unit), to connect a COM port on your computer to the Firmware Upgrade Port of your switch.

Note: On a daisy chained installation, the chained stations will automatically receive the upgrade via the daisy chain cables.

1. Shut down all the computers, but not the stations, on the KVM installation.
2. From your KVM switch console, login to the OSD as the administrator (see page 31) and select the F4 ADM function.
3. Scroll down to FIRMWARE UPGRADE. Press [Enter], then press [Y] to invoke Firmware Upgrade mode (see page 41.).

Note: During Firmware Upgrade mode, the port LEDs will flash on and off.

Starting the Upgrade

To upgrade the firmware:

1. Run the downloaded firmware upgrade package file either by double-clicking the file icon, or by opening a command line and entering the full path to it.

The Firmware Upgrade Utility welcome screen appears:

Note: The screens shown in this section are for reference only. The wording and layout of the actual screens put up by the Firmware Upgrade Utility may vary slightly from these examples.

1. Read and Agree to the License Agreement (enable the I Agree radio button).
2. Click Next to continue.

The Firmware Upgrade Utility main screen appears. The devices capable of being upgraded are listed in the Device List panel:

1. Click Next to perform the upgrade.

If you enabled Check Firmware Version, the utility compares the device's firmware level with that of the upgrade files. If it finds that the device's version is higher than the upgrade version, it brings up a dialog box informing you of the situation and gives you the option to continue or cancel.

If you didn't enable Check Firmware Version, the utility installs the upgrade files without checking whether they are a higher level, or not.

As the upgrade proceeds, status messages appear in the Status Messages panel, and the progress toward completion is shown on the Progress bar.

Upgrade Succeeded

After the upgrade has completed, a screen appears to inform you that the procedure was successful:

Click Finish to close the firmware upgrade utility.

Upgrade Failed

If the Upgrade Succeeded screen doesn't appear, it means that the upgrade failed to complete successfully. See the next section, Firmware Upgrade Recovery, for how to proceed.

Firmware Upgrade Recovery

There are three conditions that call for firmware upgrade recovery:

• When a firmware upgrade is manually aborted.
• When the mainboard firmware upgrade fails.
• When the I/O firmware upgrade fails.

To perform a firmware upgrade recovery, do the following:

1. Power off the switch. If it is part of a daisy chain, disconnect it from the chain.
2. Connect the Firmware Upgrade Cable to its Firmware Upgrade Port.
3. Slide the Firmware Upgrade Recovery Switch to the Recover position.
4. Power the switch back on and repeat the upgrade procedure.
5. After the switch has been successfully upgraded, power it off, and slide the Firmware Upgrade Recovery Switch back to the Normal position.
6. If the switch is part of a daisy chain, replace it in the chain.
7. Power the switch back on.

Optional Rack Mounting

For convenience and flexibility, three optional rack mounting kits are available:

A long bracket standard rack mounting kit for 68.0–110.0 cm racks;
♦ A short bracket Easy-Installation rack mount kit for 52.0–70.0 cm racks;
♦ A long bracket Easy-Installation rack mount kit for 68.0–110.0 cm racks.

Standard - Long

To install the long bracket standard rack mount kit, simply replace the short L brackets on the standard rack mount kit with the long ones, and mount the switch according to the instructions given for Standard Rack Mounting, page 12.

Easy Installation

With an Easy-Installation, kit, one person can mount the switch. To install the Easy-Installation kit, do the following:

1. Remove the standard L brackets, and the side mounting brackets from both sides of the switch.

1. Attach the left and right easy-installation mounting rails to the inside of the rack. The flange that supports the switch will be to the inside.

a) Screw the front flanges to the rack first.
b) Slide the bars with the rear flanges toward the rack until the flanges make contact with the rack, then screw the rear flanges to the rack.

(Continues on next page.)

(Continued from previous page.)

1. Slide the switch onto the support flanges. Use the screws supplied with this package to loosely attach the front of the switch to the front of the rack (only tighten the screws part way).

1. Slide the rear attachment sliding brackets along the slide bars until they contact the rear of the switch, then use the screws supplied with this package to attach the bars to the rear of the switch (tighten the screws all the way).

1. Slide the switch open and closed a couple of times to be sure that it is properly aligned and operating smoothly. (See p. 21 for opening and closing procedures.)

2. After determining that the switch is properly lined up and operating correctly, finish up by fully tightening down the partially tightened front attachment screws inserted in step 3.

Troubleshooting

Overview

Operation problems can be due to a variety of causes. The first step in solving them is to make sure that all cables are securely attached and seated completely in their sockets.

In addition, updating the product's firmware may solve problems that have been discovered and resolved since the prior version was released. If your product is not running the latest firmware version, we strongly recommend that you upgrade. See The Firmware Upgrade Utility, page 57, for upgrade details.

Problem Solution
There are ghost images on the external monitor.	The distance between the external console and the CL5708 / CL5716 is too great. The maximum VGA cable distance should not exceed 20m and, in some cases, may need to be shorter. Replace the VGA cable with one of an appropriately short length.

Keyboard Invocation Keys

Two dedicated keys are provided on the keyboard module to make it easy to invoke Hotkey mode and the OSD, as shown in the diagram, below

Note: These keys are toggles. Press them once to invoke the feature, press them again to exit.

About SPHD Connectors

This product uses SPHD connectors for its KVM and/or Console ports. We have specifically modified the shape of these connectors so that only KVM cables that we have designed to work with this product can be connected.
