Lightwave Communications PC ServerSwitch 2x16

1.0 PC ServerSwitch 2x16 - Introduction

The PC ServerSwitch 2x16 is an intelligent KVM switch for PC keyboard, high­resolution video and mouse for up to a 2-User by 16-server configuration. The PC
ServerSwitch 2x16 (for simplicity, it may be referred to as the “2x16”) supports
PS/2 keyboards and mice. The PC ServerSwitch 2x16 has full-time keyboard and
mouse emulation to each PC or server. This assures that there will be no
interruptions or interference to boot processes or other CPU activity. The video
switching circuitry is designed with state of the art video multiplexers that support
high-resolution graphics adapters with video resolutions of 1600 x 1200 pixels.

Figure 1: PC ServerSwitch 2x16 - Front Panel

The PC ServerSwitch 2x16 front panel has a built-in 20 character, 4 line backlit
LCD display. The top two lines display Port data for the currently-selected server
port, and the bottom lines are dedicated to real-time status monitoring. The PC
ServerSwitch 2x16 can be controlled either through on-screen menus (see section

3.0) or directly using the Up and Down buttons on the 2x16 (see Section 3.3).

The PC ServerSwitch 2x16’s rear panel provides industry-standard connections for
Keyboard, Mouse and Video for 16 Servers (Inputs), 2 USER/OUTPUT console
positions, and CONTROL and Video Cascade ports for expanded configurations
(see Section 6.0) that supports up to 96 connected servers. Also found on the back
panel is the AC power input, fuse, and Power Switch for the unit.

Figure 2: PC ServerSwitch 2x16 - Rear Panel

The PC ServerSwitch 2x16 is designed for rack mounting in a conventional 19-inch
equipment rack, requiring 2RU (3.5 inches) of rack height. The unit may also be
placed on a shelf; and the included rack mounting flanges are removable. The unit
is convection cooled and does not require a fan or air conditioning.

2.0 PC ServerSwitch 2x16 - System Information

2.1 Video

The PC ServerSwitch 2x16 incorporates an active, high-bandwidth switch for
graphics adapter cards supporting resolutions up to 1600 x 1200 pixels. A constant
impedance of 75 ohms is maintained on all video lines in the 2x16, so that the
video signal is not compromised by mismatched impedance. Monitor sense lines
are also transported by the PC ServerSwitch 2x16. The ID lines are buffered and
passed from the monitor to the attached graphics adapters in the servers.

2.2 Keyboard / Mouse

The PC ServerSwitch 2x16 is an intelligent switch for the keyboard and mouse.
Each port emulates the keyboard and mouse fully, allowing an attached server or
PC to boot without having been previously selected. Power for each connected
device is monitored from the keyboard port.

If there is no connection on a keyboard port, an error message will be displayed
on the front panel display. The attached servers are not affected because of the
keyboard and mouse emulati on.

Each port maintains a local copy of the keyboard and mouse configuration. When
the user switches from one port to another, the keyboard is set up just as it was
prior to switching to another port. The mouse behaves in a similar manner.

2.3 System Control

The PC ServerSwitch 2x16 is controlled either by using the UP and DOWN arrows
on the front panel of the unit or via On-Screen Menus from their Console
(Keyboard, Monitor and Mouse).

The 2x16 is a transparent device to the User. The User (of which there may be one
or two) can select which server they wish to access from their Console, from up to
16 connected Servers. In cases where two or more 2x16 units have been
cascaded, additional Servers can be accessed by the two Users, up to a maximum
of 96 Servers.

To access the 2x16’s switching capability, the User must “wake up” the on-screen
display to control the system by pressing both ‘Cntl’ keys simultaneously (referred
to as ‘Cntl-Cntl’) or press the Scroll Lock key twice on their PS/2 keyboard.

If the User is near the 2x16 (for example, in a backroom location), the User may
instead select a server by using the Up and Down buttons on the front of the Unit.
The display will show which Servers are a vailable. To select between User A and
User B, press both the Up and Down buttons on the front panel of the 2x16 at the
same time to shift between the two users.

3.0 On-Screen Menus

On-screen Menus are used for two purposes:

• Server Port selection for a Console

• System setup programming for the PC ServerSwitch 2x16

On-Screen Menus are displayed on the User's monitor. Either Console may
administer the system, but only one user may edit the setup at a time.

NOTE: While in the on-screen menu mode, the "Caps Lock", "Num Lock", and

"Scroll Lock" LEDs will flash on the User Console’s keyboard.

Navigating the on-screen menus

• Press both Control keys (Cntl-Cntl) to access the on-screen menus, or
press the Scroll Lock key twice

• Up Arrow/Down Arrow

• + and - keys on number pad

• Enter (select or scroll through options)

• Esc to exit, or to back up one level

• Most options have a single-character hot-select key, highlighted and

capitalized on the screen. Press that letter to select that option.

3.1 Main Menu

Pressing and releasing both CONTROL buttons (Ctrl-Ctrl) on either Console's
keyboard will bring up the main menu of the PC ServerSwitch 2x16.

Main Menu Options

Navigate through the Main Screen window by using the up and down arrows on
your keyboard and “Enter” to select from the following:

• System Setup - for customizing your PC ServerSwitch 2x16.

• Auto Scan - This option scans each attached port for a duration

determined by the user. See Section 3.1.1.

• Jump to port... - You can jump to specific ports several different ways.
By selecting “Jump to port...”, navigate by typing either the name or
number of the desired port. Press [J] and press Enter to get a prompt to
enter the server Port name or number. See Section 3.1.2.

• Disabled - Select this entry to disconnect this User Console (A or B) from
all Server ports (enabling the other user to access all Server ports).

• Ports 1 through 8 - direct-select an association with Server Ports 1
through 8

• Next unit - go to the Next page of eight server ports using [N].

• Prev unit - go to the Previous page of eight server ports using [P].

• Esc exits - press [Esc] to exit the server window. If Scanning is enabled,

port scanning will start upon exiting.

NOTE: You can set up your PC ServerSwitch 2x16 options, port names, etc.

before you connect your PCs or servers.

The preset values do not list any server names, but instead identify each port with
a generic Port number. The Port Number is fixed and always displayed, even if the
user enters a name.

System Setup Options

System Setup Options are used for system maintenance and software updates.
The System Setup options are also accessible from the Main Menu Screen, by
pressing the F1 key to access the System Setup screen. System Options include
System Flash Memory Update (F) and Load Factory Settings (F12).

Caution: Do NOT use System Setup Options during normal operation, as these
will erase all user-entered data and may require a system reset. Updating the
FLASH memory requires that the System re-enumerate (reboot) which can
interrupt normal operation.

Refer to Section 7 for System Maintenance features and instructions.
