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.

4.0 Operational Safety

The PC ServerSwitch 2x16 should be installed in a suitable equipment room
environment. It is designed for rack mounting in a 19-inch equipment rack.

A) The PC ServerSwitch 2x16 is designed to operate in an ambient temperature of
0°C (32°F) to 50°C (122°F), 10-90% humidity, non-condensing. Ensure that closed
or multi-unit racks maintain an ambient temperature not to exceed 50 °C (122 °F).

B) The PC ServerSwitch 2x16 is designed to operate with convection cooling
provided by the air holes located in both sides of the unit. Heat flow rate is 82
BTU/hour. Make sure that these ventilation holes are not obstructed by equipment
placed directly in contact with either side of a PC ServerSwitch 2x16.

If the unit is placed on a shelf, be sure to allow air space around the unit for air
flow, especially to the sides of the unit. The unit is shipped with four rubber feet
which will raise the unit off of a co unter or shelf and allow air flow beneath the unit.

C) Make sure that each PC ServerSwitch 2x16 unit is properly supported in the
front of the unit, by bolting the PC ServerSwitch 2x16 into a standard 19 inch rack.

D) The PC ServerSwitch 2x16 has a universal power supply which requires
85-264 VAC, 47-63 Hz at 1 ampere. Power consumption is 24 watts. It is important
for each unit to be supplied with the proper operating voltage and current.

E) All rack mounted equipment should be reliably connected to earth ground. Pay
close attention to grounding at all times, particularly when equipment is not directly
connected to power mains (such as when a power strip is used).

WARNING: The top cover should not be removed due to the potentially

hazardous voltages in the unit. No user serviceable parts are
inside the PC ServerSwitch 2x16. All repairs should be
performed by Lightwave to avoid cancellation of the warranty.

Note: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of FCC Rules. These limits are designed to provide a
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.

Lightwave Communications PC ServerSwitch 2x16

5.0 Installation

The PC ServerSwitch 2x16 unit is designed to occupy 3.50 inches of rack space.
Sufficient space is required behind the rear panel of the unit to allow for attached
cables bend radius (6 inches should be sufficient). It is helpful to plan ahead if
additional units might be added to the configuration at some later date. If
cascading (adding PC ServerSwitch 2x16’s) is to be used, make certain to leave
enough space in the rack for additional units. The PC ServerSwitch 2x16
installation can be expanded at any time, without interfering with servers
connected to existing switches.

STEP 3 -- Connecting CPUs

Referring to Figure 4, connect a single PC to the PC ServerSwitch 2x16 and verify
its operation. Use the cables that were purchased with the PC ServerSwitch 2x16
to attach the PC. Connect the cables in the following order:

Make certain that all PCs are powered off when connecting them to the PC
ServerSwitch 2x16. It is important to note that some servers do not allow for
keyboards to be connected and disconnected during operation. This may cause
them to halt.

1) A Mini-DIN6 male-to-male cable from the Server keyboard connector to
the PC ServerSwitch 2x16. Maximum length is 25 feet.

2) A Mini-DIN6 male-to-male cable from the Server mouse connector to the
PC ServerSwitch 2x16. Maximum length is 25 feet.

3) An HD15 male-to-male video cable from the Server graphics adapter to
the PC ServerSwitch 2x16.

Once step three is complete, continue to connect the remaining PCs. Repeat step
three until all of the devices are connected.

NOTE! CPUs can be connected to any port. It is not necessary to use Port 1

as the first connection, Port 2 as the second, etc.

6.0 Cascading the PC ServerSwitch 2x16

This section only applies to configurations with more than one PC ServerSwitch
2x16. Up to six (6) PC ServerSwitch 2x16 units may be cascaded for a maximum
of 96 server ports and 2 Console Ports. See Figure 8.

Figure 8: Cascading PC ServerSwitch 2x16 systems (3 units shown)

www.lightwavecom.com Page 20 of 24

Lightwave Communications PC ServerSwitch 2x16

If more than sixteen servers are to be connected, then cascading of the PC
ServerSwitch 2x16 is necessary. In a cascade environment, the first unit that is
installed is considered the "Master Unit." All information is stored in the Master
Unit. Cascading the units is very simple.

If the existing PC ServerSwitch 2x16 unit has been installed and running, it is not
necessary to turn off the power to the Unit. The installation of additional units can
be accomplished without any interruption to the existing servers.

STEP 1 - Connect CONTROL Cable

Connect the DB9 Serial data cable (supplied with each PC ServerSwitch 2x16)
from the Master Unit "Control Out" port to the first Aux Unit "Control In" port. Make
certain that these cables are securely fastened to the units. These data cables
carry all mouse, keyboard, and control data necessary for cascading units. Follow
this procedure for as many Aux units

If more units are cascaded, connect the Control Out port to the Control In port of
the next unit to be cascaded, using a DB9 Female to Male serial cable.

STEP 2 - Connect Video Cascade Cables

Connect the "Video Cascade In" ports on the Master Unit to the "USER/OUTPUT"
video ports (Port A Output to Port A Cascade In, Port B Output to Port B Cascade
In). This will allow the video signals from the Aux units to reach the Consoles that
are connected to the Master unit. Follow this procedure for as many Aux units (one

Master plus 5 Auxiliary units, max) as required for the servers.

STEP 3 - Turn the Auxiliary Unit On

Turn on all of the Auxiliary units that were installed. Connect the servers to these
units as done in the earlier installation for a single unit.

To install a PC ServerSwitch 2x16 as the new master, turn the old master off,
connect it, and then turn it back on. Turning off the old master may affect PCs
connected to it, so it is recommended that you shut down any PCs connected to
the old master before performing this installation.
