This document presents the results of the Linux Compatibility tests, which included the testing of Redhat 9.0, Redhat Enterprise Server 3.0, SuSE 9.1, and SuSE Linux Enterprise Server 9 with the Avocent DSR™ 1020, 2020 and 4020 switches.
AppLabs' Linux compatibility testing of this system showed the Avocent DSR™ 4020 series of switchs to be compatible with Redhat 9.0, Redhat Enterprise Server 3.0, SuSE 9.1, and SuSE Linux Enterprise Server 9 The Avocent DSR™ 1020, 2020 and 4020 switches are awarded the AppLabs Linux Compatibility mark.
System Configuration
The following table defines the system configuration tested by AppLabs.
| KVM Hardware Tested |
|
This document covers the setup and testing of the Avocent DSR™ 1020, 2020 and 4020 KVM units in the context of a Linux environment. The testing
attempts to ensure that the unit will function as advertised when used with the Linux OS.
All testing of the DSR™ 1020, 2020 and 4020 switches were done in a mixed OS environment.

| Other Hardware |
Video Monitor: Dell UtlraScan P780 color monitor
Mouse: IBM PS/2 mouse
Keyboard: IBM standard keyboard
CPU 1, Compaq Deskpro EN 933Mhz, 512 MB RAM, 9 GB hard drive for Linux distributions.
CPU 2, Gateway Desktop 1GHz, 256 MB RAM, 40 GB hard disk for Microsoft Windows 2000 platform.

Testing Results
The following table provides the pass/fail result for the hardware as tested in this system by AppLabs.
| INSTALL THROUGH TEST |
| Install Linux on one or more CPUs while connected to the DSR™ 1020 switch. | PASS |
| Notes: All four distributions installed through
the KVM with no problems.
|
| POWER CYCLE |
| Verify the DSR™ 1020 switch is state-independent of its controlled CPUs. | PASS |
| Notes: Power cycling indicated no problems with any
of the Linux Distributions.
|
Switching Commands Testing
| HOT KEY SWITCHING |
| Verify switching works with Linux keyboard drivers. | PASS |
| Notes: |
| AUTO SWITCHING |
| Verify auto switching works with Linux drivers. | PASS |
| Notes:
|
| PS/2 or SERIAL MICE POINT, CLICK, DRAG |
| Verify the functioning of the mouse as the KVM switches between the various CPUs | PASS |
| Notes: Mouse performed well with no negative effects
when being switched between the connected CPUs.
|
Monitor Testing
| DISPLAY RESOLUTION TEST |
| Verify the stability of cycling through the various CPUs with X
operating on each and at different resolutions | PASS |
| Notes: The Linux distributions worked at various
screen resolutions.
|
| MONITOR ON/OFF TEST |
| Verify the stability of the displays on the various CPUs when the KVM monitor is turned off and on during cycling | PASS |
| Notes: The power state of the monitor did not effect the
state of the CPUs.
|
| IDLE TIME TEST |
| Verify the KVM can recover from idle periods without loss of keyboard, monitor or mouse contact. | PASS |
| Notes: The KVM was unaffected by periods of idle time and remained functional. |
Multiple OS Test
| With Microsoft Windows 2000 |
| Verify the continued functionality of the connected CPUs and KVM units when running different operating systems on one or more of the connected CPUs | PASS |
| Notes: The KVM showed no adverse effects when switched between the various OSes and remained functional.
|
Notes and
Observations:
This device was tested using the following manufacture recommend settings for Linux; video adapter is non-interlaced and is set to a supported video resolution and refresh rate, and mouse acceleration is turned off.
