Features and Benefits

The DS1800 digital solution provides secure, non-blocked KVM connections to virtually any number of servers using a standard LAN connection.

Operators can connect to servers no matter where they are located with performance that meets the requirements of both local and remote operators.

Because the DS1800 leverages industry standard LAN equipment, complex wired configurations are no longer necessary. All of the analog KVM signals are converted in real time to digital form and transported using standard

Ethernet protocols. This design allows for your future growth needs without complex reconfiguration.

DS1800 Installer/User Guide

PCs can be located anywhere a valid network connection exists. The DS1800 can be configured on a separate network “out of band” of your data network, allowing access to your servers even if your applications network is down.

Safety Precautions

To avoid potential video and/or keyboard problems when using Avocent products:

• If the building has 3-phase AC power, ensure that the computer and monitor are on the same phase. For best results, they should be on the same circuit.

• Use only Avocent-supplied cable to connect computers and KVM switches. Avocent warranties do not apply to damage resulting from usersupplied cable.

To avoid potentially fatal shock hazard and possible damage to equipment, please observe the following precautions:

• Do not use a 2-wire extension cord in any Avocent product configuration.

• Test AC outlets at the computer and monitor for proper polarity and grounding.

• Use only with grounded outlets at both the computer and monitor. When using a backup power supply (UPS), power the computer, the monitor and the DS1800 unit off the supply.

NOTE: The AC inlet is the main disconnect.

DC installation safety considerations

As a safety precaution, install this product in an area with limited or controlled access. A readily accessible disconnect device that is suitably approved and rated shall be incorporated in the field wiring. Connect field wiring from the

48 VDC power source to the screw terminals marked plus (+) and minus (-) on the rear panel of the unit. Connect field wiring from earth ground to the screw terminal marked with the ground symbol. Terminals will accommodate wiring from 26 to 12 AWG (up to 2.5 mm

Chapter 2: Installation


The DS1800 system requires that the DSView, DSAdmin and

DSAuthentication Service software be installed prior to use. DSView is the application which allows a user to view and control a server attached to the DS1800 system. DSAdmin is used to configure and maintain the system.

DSAuthentication is a Windows NT or 2000 service used to prevent unauthorized access to the DS1800 system. For more information on these programs, see your DSView Installer/User Guide.

The DS1800 system uses Ethernet networking infrastructure and TCP/IP protocol to transmit keyboard, video and mouse information between operators and connected computers. Although 10BaseT Ethernet may be used, Avocent recommends a dedicated, switched 100BaseT network.

Power Up and LEDs

The DS1800 should be powered up before any attached servers or switches.

Indicator lights on the front of the unit will illuminate to indicate the status and activity of each port and a green LED labeled Power will show that the unit is receiving power.

There are two LEDs above each port number on the front of your unit: one green and one amber. The green LED will illuminate when the attached system or switch is powered. The amber LED will illuminate when that computer or a computer attached to that switch is being accessed by a

DSView client.

There are also LEDs on the DS1800 front panel to indicate the status of your

LAN connection. If you are successfully linked to the network, the green LED labeled Link will be lit and an amber LED labeled 10/100 will indicate that you are communicating at the proper speed. This LED will blink if there is activity on the associated DS1800 unit.

Finally, you will find a 9-pin serial connector labeled Terminal on the right end of the front panel of the DS1800. This is used to configure the DS1800 and will be discussed further in Chapter 4.

Once the DS1800 is configured and powered, users may connect to attached systems through the DSView software. For more information on DSView, see the DSView Installer/User Guide.

Terminal Operations

Each individual DS1800 may be configured at the unit level through the terminal port on the front of the unit. All Terminal commands are accessed through a terminal or PC running terminal emulation software.

18


To access the Terminal menu:


HyperTerminal) to the terminal port on the front panel of the DS1800 using the supplied null-modem cable. The terminal should be set to 9600 baud, 8 bits, 1 stop bit, no parity and no flow control. The terminal may be connected at any time, even when the unit is powered.

2. Press any key to access the main menu.

Terminal Applications Menu Commands

The main menu of the DS1800 features the following selections: Network

Configuration, Security Configuration, SNMP Configuration, Firmware Management, Enable Debug Messages, Set/Change Password, Restore Factory

Defaults, Reset Appliance and Exit. Each is discussed below.

Network Configuration

The DS1800 is configured for network access through this option. When it is selected, you will have access to the addressing that allows the DS1800 to be positioned in your network.

Security Configuration

This menu option allows you to configure DS1800 authentication security. When it is selected, you will be given two menu options: Reset Authentication Tokens and Authentication Server Connection Status.

The DS1800 operates in one of two modes: All or Secure. This setting is controlled from the Security menu on the DS1800 console port. In the default

All mode, the DS1800 allows any authentication server to initiate a session between the DS1800 and DSView. In Secure mode, only one specific authentication server is allowed to initiate this session; other authentication servers are locked out.

NOTE: In Secure mode, the ability to select a backup authentication server through DSView is eliminated.

When a DS1800 is added to the database with DSAdmin, the appropriate authentication token is added to the DS1800 automatically. If DSAuthentication cannot contact the DS1800 to add the token, an error message is displayed and the DS1800 is not added to the database.

When the last reference to a DS1800 is removed from the database, the authentication token is removed from the DS1800, which allows the DS1800 to be


19

18

DS1800 Installer/User Guide Chapter 3: Operations

19

moved from one authentication server to another. The authentication token can also be removed from the Security menu on the DS1800 console port via the Reset Authentication Tokens option.

When the DS1800 is in All mode, DSAdmin displays a warning message when the DS1800 is added to the database, stating that the token could not be installed. If you intend to operate in All mode, you may safely ignore this warning. Otherwise, you may wish to change the security settings on the console port of the DS1800.

SNMP Configuration

The SNMP Configuration menu option allows you to enable SNMP and specify parameters for SNMP operation. The DS1800 supports an SNMP MIB agent that provides read/write access to the MIB-II variables except for the EGP group. DS1800 does not implement External Gateway Protocol.

DS1800 implements the following MIB-II traps: coldStart (all reboots will be cold start traps), linkUp and authenticationFailure.

The DS1800 MIB agent provides one read community name, one write community name and one trap community name. Community names must be correctly provided in all standard SNMP messages. SNMP Get and GetNext requests must contain the read community name. SNMP Set requests must contain the write community name and SNMP traps must contain the trap community name.

Firmware Management

This menu option allows you to access the FLASH Download command which allows you to upgrade your DS1800 firmware with upgrades available from

Avocent. For more information on FLASH upgrading your DS1800, see Appendix

A: FLASH Upgrades.

Enable Debug Messages

This menu option allows you to configure the DS1800 to display messages regarding the status of the DS1800 unit. Once you select the level of detail you wish to receive, the DS1800 will begin to display information on your terminal screen. When you are finished viewing, press any key to exit this mode.

Appendix D: TCP Ports

When the DSView client is started, the Node Manager will become active.

Node Manager will try to establish a SSPI Messenger Class session using

TCP/IP over port 2068 to the DSAuthentication Server (Avocent Service).

First, Node Manager will use the current NT/2000 cached credentials to establish the session. If the cached credentials have the proper permissions, the browse list is returned from the DSAuthentication Server over TCP/IP port 2068.

NOTE: The DSView client caches the browse list. Using the refresh option will update the list from the DSAuthentication Server.

If the session is refused using the cached credentials, a pop-up dialog box will prompt for the proper username and password.

TCP/IP port 8192. The DS1800 verifies with the DSAuthentication Server that the calling DSView client has permission to have a KVM session with the selected port. Then the connection between the DS1800 and the

DSAuthentication Server is closed. All communication between the DS1800 and the DSView client takes place over TCP/IP port 8192 until the DSView client closes the session.

DSAdmin functions similarly to the DSView client. It establishes a connection using TCP/IP port 2068, and uses the same process for authentication and return of the browse list. Changes made to the browse list through DSAdmin are transmitted back to the DSAuthentication Server using TCP/IP port 8190.

After the changes are made, DSAdmin refreshes its browse list view over the

TCP/IP port 2068 connection.

When the backup Authentication Service is active, it communicates with the primary Avocent Authentication Service via TCP port 8193. Changes to the topology are copied to and from the primary over this port.
