Avocent DSR® switches combine analog and digital technology to provide flexible, centralized
control of data center servers and facilitate the OA&M (operations, activation and maintenance) of
remote branch offices where trained operators may be unavailable. They provide enterprise
customers with a significant reduction of cable volume, secure remote access and flexible server
management from anywhere at anytime.
Each DSR switch model consists of a rack mountable keyboard, video and mouse (KVM) switch,
configurable for analog (local) or digital (remote) connectivity. Video resolutions are supported
up to1280 x 1024 for remote users. Enhanced video quali ty of up to 16 00 x 1200 is available to
local users via the video port.
The DSR switch has user peripheral ports for PS/2 and USB keyboards and mice and an SPC port
that may be used to connect to an SPC power control device. An SPC device is an 8- or 16-outlet
device that can be used to control the power state of any attached target devices using the
DS software.
The DSR switches work over standard LAN connections. Users can access target devices
across a 1000BaseT LAN port that is used to establish an Ethernet connection, or directly
through a local port. Each DSR switch model includes a MODEM port that supports V.34, V.90
or V.92-compatible modems that may be used to access the switch when an Ethernet
connection is not available.
The IP-based DSR switches give you flexible target device management control from anywhere in
the world.

Reduce cable bulk
With server densities continually increasing, cable bulk remains a major concern for netw ork
administrators.The DSR switches significantly reduce KVM cable volume in the rack by utilizing
the innovative DSRIQ module and single, industry-standard Unshielded Twisted Pair (UTP) CAT
5 cabling. This allows a higher server density while providing greater airflow and cooling capacity.
The DSRIQ module is powered directly from the target device and provides Keep Alive
functionality when the DSR switch is not powered.
2 DSR Switch Installer/User Guide
The DSRIQ-SRL (serial) module is a DCE device that provides the primary interface between a
serial device and a DSR switch. It provides VT100 terminal emulation, break suppression and port
history in a compact, convenient module.
Access the DSR switch via network connection
No special software or drivers are required on the attached, or client, computers.
NOTE: The client connects to the server housing the DSView® management software using an Internet browser.
For modem access, you must install DSR Remote Operations software included on the DSView software
CD-ROM (see the DSView Installer/User Guide for more information).
Users access the DSR switch and all attached systems via Ethernet or using a V.34, V.90 or V.92
modem from a client computer, such as a PC. Clients can be located anywhere a valid network
connection exists.
Simple access to any target device
When a user accesses the DSView Server software, a listing of all target devices to which the user
has permission to view and manage is displayed. When a user selects a target device from the list,
the video of the selected target device is displayed in a Video Viewer window.

Safety Precautions
To avoid potential video and/or keyboard problems when using Avocent products:
•If the building has 3-phase AC power , ensure th at the co mputer and monit or are on the same phase.
For best results, they should be on the same circuit.
To avoid potentially fatal shock hazard and possible damage to equipment, please observe the
following precautions:
•Do not use a 2-wire power cord in any Avocent product configuration.
•T est AC outlet s at the t ar get device and moni tor for proper po larity and grou nding.
•Use only with grounded outlets at both the tar get device an d monitor. When using a backup
Uninterruptible Power Supply (UPS), power the tar get device, the monitor and th e DSR switch from
the UPS.
NOTE: The AC inlet is the main power disconnect.
Rack mount safety considerations
•Elevated Ambient Temperature: If installed in a closed rack assembly, the operating temperature of
the rack environment may be greater than room ambient. Use care not to exceed the rated maximum
ambient temperature of the switch.
•Reduced Air Flow: Installation of the equipment in a rack should be such that the amount of airflow
required for safe operation of the equipment is not compromised.
•Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.
•Circuit Overloading: Consideration should be given to the con nection of the equipment to the supply
circuit and the effect that over loading of circu its might have on overcurrent pro tection and supply
wiring. Consider equipment nameplate rating s for maximum curr ent.
•Reliable Earthing: Reliable earthing of rack mou nted equipment sho uld be maintained . Pay
particular attention to supply connections other than direct connections to the branch circuit (for
example, use of power strips).
CHAPTER

The DSR switching system requires connectivity to a server running the DSView Server software.
DSView software allows a user to view and control target devices (one at a time) attached to the
DSR switching system. For more information on the DSView software, see the DSView
Installer/User Guide.
The DSR switching system transmits keyboard, video and mouse (KVM) information between
operators and target devices attached to the DSR switch over a network using either an Ethernet
connection or a modem connection.
The DSR switch uses TCP/IP for communication over Ethernet. Although 10BaseT Ethernet may
be used, Avocent recommends a dedicated, switched 100BaseT network, or even a
1000BaseT network.
The DSR switch uses the Point-to-Point Protocol (PPP) for communication over a V.34, V.90 or
V.92 modem.

Verifying the Connections
DSR switch
The front panel of the DSR switch features two LEDs indicating the Ethernet connection. The top
green LED is the Link indicator. It will illuminate when a valid connection to the network is
established and blink when there is activity on the port. The lower amber/green LED, labeled 100/1000, will indicate that you are communicating at the 100 Mbps rate (amber) or the 1000 Mbps rate
(green) when using an Ethernet connection.
Additionally, there are two LEDs above each port number on the front of your DSR switch to
indicate the target device status: one green and one amber. The green LED will illuminate when the
attached target device is powered. The amber LED will illuminate when that port is selected.
DSRIQ modules
PS/2, Sun and USB DSRIQ modules are available for attaching computers to your DSR switch.
The DSRIQ-SRL serial module is used to connect serial devices to your DSR switch and features
two green LEDs: a POWER LED and a STATUS LED. The POWER LED indicates that the
attached DSRIQ-SRL is powered. The STATUS LED indicates that a valid selection has been made
to a DSR switch. The DSRIQ-SRL module prevents a serial break from the attached device if the
module loses power. However, a user can generate a serial break with the attached device by
pressing
Alt-B after accessing the Terminal Applications menu.

Setting the keyboard country code
NOTE: Using a keyboard code that supports a language different from that of your DSR switch firmware will
cause incorrect keyboard mapping.
Sun servers may use keyboard mappings for non-US keyboards. By default, the DSR switch sends
the US keyboard country code to Sun and USB modules attached to target devices and the code is
applied to the target devices when they are powered up or rebooted. Codes are then stored in the
DSRIQ module.
Issues may arise when you use the US keyboard country code with a keyboard of another country.
For example, the
keyboard. Sun servers will interpret pressing the
when the US keyboard country code is used.
The Keyboard dialog box enables you to send a different keyboard country code than the default
US setting. The specified country code is sent to all target devices attached to the DSR switches
when they are powered up or rebooted and the new code is stored in the DSRIQ module.
Z key on a US keyboard is in the same location as the Y key on a German
Y key on a German keyboard as pressing the Z key
NOTE: If a DSRIQ module is moved to a different target device, the keyboard country code will need to be reset.
See Appendix F for information on emulating certain Sun keys using a PS/2 keyboard and special
considerations for Japanese and Korean Sun USB keyboards.
NOTE: Only local users can view or change keyboard country code settings.

Reset Certificates
This menu option enables you to clear the certificate sent by the DSView software to the
DSR switch.
When a DSR switch is added to a server running DSView software, a certificate is downloaded
from that server to the DSR switch automatically. That certificate is replicated across all servers
running DSView software operating in a predefined system. Thereafter, any of the servers in that
system will be able to communicate with the DSR switch.
If the server running DSView software cannot contact the DSR switch to add the
certificate, an error message is displayed and the DSR switch is not added to the database.
Secure Mode
The DSR switch operates in one of two modes: Security disabled or Security enabled.
In Security disabled mode, the DSR switch allows any server running DSView software to
communicate with it.
In Security enabled mode, an initial server running DSView software is allowed to download a
certificate to the switch. If that server is part of a system that replicates certificates, it will pass
the certificate to the other servers in that certificate replication system. Thereafter, all servers in
that system will be allowed to access the DSR switch. All servers that are not part of that system
will be locked out.
When the DSR switch is removed from the DSView software database, the certificate is
removed from the DSR switch. This enables you to move the DSR switch from one certificate
44 DSR Switch Installer/User Guide
replication system to another. The certificate can also be removed using the Console menu

Appendix B: Using DSView Software Over a Modem Connection
An external modem may be attached to the DSR switch. This modem may be used to access the
switch when an Ethernet connection is not available.
A modem/PPP dial-up connection must be established before the remote operation is enabled. The
dial-up connection options should be set to 115,200 bps, 8 bits, 1 stop bit, no parity and enabl ed
hardware flow control.
Before you begin
The following actions should be performed before using the DSR Remote Operations software:
•Ensure that the DSR switch is configured. See Chapter 2 for more inf or mation.
•Ensure that DSR switch users have been added to the DSR switch internal database. If the
DSView Server software is not available, the switch database is used for authentication. If
neither are available, authentication cannot be performed for the DSR switch. See
for more information.
•Ensure that an external modem is attached to the DSR switch MODEM port. The modem
should have auto-answer turned off (typically a modem’s default setting).
•Ensure th at your client PC contains dial-up software and that the software is configured

Appendix C: Using DSRIQ-SRL Modules
The DSRIQ-SRL module is a serial-to-VGA converter which permits VT100-capable devices to be
viewed from the DSR switch local port or by using the DSView software. The actual serial data is
not accessed, but is merely displayed. All serial data coming from the target device is displayed in a
VT100 window, placed into a video buffer and sent to the DSR switch as though it came from a
VGA target. Likewise, keystrokes entered on a keyboard are sent to the attached device as though
they were typed upon a VT100 terminal.
DSRIQ-SRL module modes
The following modes can be accessed from the DSRIQ-SRL module:
•On-Line: This mode enables you to send and receive serial data.
•Configuration: This mode enables you to specify DSR switch communication parameters, the
appearance of the Terminal Applications menu and key combinations for specific actions
and macros.
•History: This mode enables you to review serial data.
Configuring the DSRIQ-SRL module
NOTE: The DSRIQ-SRL module is a DCE device and only supports VT100 terminal emulation.
Pressing Ctrl-F8 will activate the Configuration screen of the DSRIQ module’s Terminal
Applications menu, which enables you to configure your DSRIQ-SRL module.
NOTE: When any Terminal Applications menu is active, pressing Enter saves changes and returns you to the
previous screen. Pressing Escape returns you to the previous screen without saving changes.
Within the Terminal Applications menu’s Configuration screen, you can modify the
following options:
•Baud Rat e: This option allows you to specify the serial port communications speed. A v ailable
options are 300, 1200, 2400, 9600, 19,200, 34,800, 57,600 or 115,200 bps. The default value
is 9600.
•Parity: This opti on allows you to specify the serial port’s communications parity. Available

Appendix D: UTP Cabling
The following information is intended to brief you on various aspects of connection media. The
performance of a DSR switching system depends on high quality connections. Poor quality or
poorly installed or maintained cabling can diminish DSR system performance.
NOTE: This appendix is for information purposes only. Please consult with your local code officials and/or
cabling consultants prior to any installation.
DSR switching systems utilize UTP cabling.
UTP copper cabling
The following are basic definitions for the three types of UTP cabling that the DSR
switch supports:
•CAT 5 UTP (4-pair) high performance cable consists of twisted pair conductors, used
primarily for data transmission. The twisting of the pairs gives this cable some immunity from
the infiltration of unwanted interference. CA T 5 cable is generally used for networks running at
10 or 100 Mbps.
•CAT 5E (enhanced) cable has the same characteristics as CAT 5, but is manufactured to
somewhat more stringent standards.
•CAT 6 cable is manufactured to tighter requirements than CAT 5E cable. CAT 6 has higher
measured frequency ranges and significantly better performance requirements than CAT 5E
cable at the same frequencies.
Wiring standards
There are two supported wiring standards for 8-conductor (4-pair) RJ-45 terminated UTP cable:
EIA/TIA 568A and B. These standards apply to installations utilizing CAT 5, 5E and 6 cable
specifications. The DSR switching system supports either of these wiring standards. Please refer to
the following table for details.
The following is a list of important safety considerations that should be reviewed prior to installing
or maintaining your cables:
•Keep all CAT 5 runs to a maximum of 10 meters each.
•Maintain the twists of the pairs all the way to the point of termination, or no more that one-half
inch untwisted. Do not skin off more than one inch of jacket while terminating.
•If bending the cable is necessary, make it gradual with no bend sharper than a one inch radius.
Allowing the cable to be sharply bent or kinked can permanently damage the cable’s interior.
•Dress the cables neatly with cable ties, using low to moderate pressure. Do not over
tighten ties.
•Cro ss-connect cables where necessary, using rated punch blocks, patch panels and
components. Do not splice or bridge cable at any point.
•Keep CAT 5 cable as far away as possible from potential sources of EMI, such as electrical
cables, transformers and light fixtures. Do not tie cables to electrical conduits or lay cables on
electrical fixtures.
•Always test every installed segment with a cable tester. “Toning” alone is not an
acceptable test.
•Always install jacks so as to prevent dust and other contaminants from settling on the contacts.
The contacts of the jack should face up on the flush mounted plates, or left/right/down on
surface mount boxes.
•Always leave extra slack on the cables, neatly coiled in the ceiling or nearest concealed
location. Leave at least five feet at the work outlet side and 10 feet at the patch panel side.
•Choose either 568A or 568B wiring standard before beginning. Wire all jacks and patch panels
for the same wiring scheme. Don’t mix 568A and 568B wiring in the same installation.
•Alw ays obey all local and national fire and building codes. Be sure to firestop all cables that
penetrate a firewall. Use plenum rated cable where it is required.

These key combinations will work with the DSRIQ-USB module (if your Sun system comes with a
USB port) as well as the Sun DSRIQ-VSN and DSRIQ-WSN modules. With the exception of
these key combinations are not recognized by Microsoft Windows. Using

When finished, press and hold Ctrl+Shift+Alt and then press the Scroll Lock key to toggle Sun
Advanced Key Emulation mode off.
Special considerations for Japanese Sun USB and Korean Sun
USB keyboards (DSRIQ-USB modules only)
Japanese Sun USB and Korean Sun USB keyboards assign usage IDs for certain keys that differ
from standard USB usage IDs. If DSRIQ-USB modules are attached to your Sun servers, the Han/
Zen and Katakana/Hiragana keys on Japanese Sun USB keyboards and Hangul and Hanja keys on
Korean Sun USB keyboards must be accessed using alternate keystrokes.
Due to these keyboard-specific differences, keyboard mapping inconsistencies may be encountered
when switching between target devices using Sun DSRIQ-VSN and DSRIQ-WSN modules and
target devices using DSRIQ-USB modules. These keys function normally if your Sun servers are
attached to the DSR switch using a DSRIQ-VSN or DSRIQ-WSN module.
The following table lists the keyboard mapping that will take place when a DSRIQ-USB module is
used in this setting.
