The DSRIQ-SRL (serial) module is a DCE device that provides the primary interface between a serial device and a DSR appliance. It provides VT100 terminal emulation, break suppression and port history in a convenient module. The DSRIQ-SRL is compatible with the ARI port of a DSR system. These DSRIQ modules eliminate the need for extra rack space or additional cables. The connection between the DSR system and DSRIQ modules is via industry standard UTP cabling. DSR Installer/User Guide DSR Installer/User Guide No special software or drivers are required on the attached, or host, computers. Users access the DSR appliance and all attached systems via Ethernet from a PC running the DSViewTM application residing on the user PC. User PCs can be located anywhere a valid network connection exists. The DSR appliance can be configured on a separate network from your data network, allowing access to your servers even if your applications network is down. Simple point and click access to any server When a user activates DSView, it will display a listing of all computers and serial devices to which the user has permission to access. When a user selects a computer from the list, the video of the selected computer is displayed in a session window. Multiple servers can be accessed by one user. Each additional computer’s video will appear in a separate program window. Create and manage user permissions with DES encrypted security An administrator describes the configuration of computers attached to the DSR using an application called DSAdmin. Once the topology is described, the administrator then establishes which computers a user has permission to access. Usernames and passwords are derived from Windows NT®, eliminating the need for redundant user databases. Once the topology is established, the DSAuth software manages the system’s user permissioning. DSView polls the server running DSAuth for access permissions on power up and every time a switch is initiated for the most current permissions possible. A refresh is also available for immediate updates to a user’s access profile. In addition to the permissioning function, DSAuth also stores pertinent information about attached devices in a database. Room location, rack location and computer type can all be stored for quick reference. Access serial devices If an Avocent CPS810 or CPS1610 appliance is attached to the DSR unit, operators can gain access to serial devices through the DSView software. When a user connects to the network using DSView, a listing of all computers and serial devices to which the user has permission to access displays. Selecting a serial device will initiate a Telnet session.

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. • 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 Uninterruptible Power Supply (UPS), power the computer, the monitor and the DSR appliance off the supply. NOTE: The AC inlet is the main disconnect. 1 3 5 7 9 11 13 15 2 4 6 8 10 12 14 16 100-240V , 1.0A, 50-60 Hz LAN 1 3 5 7 9 11 13 15 2 4 6 8 10 12 14 16 LAN 1 3 5 7 9 11 13 15 2 4 6 8 10 12 14 16 LAN DSR 800 DSR 1010 DSR 2010 DSR 4010 Number of servers Digital sessions/ output Analog user 8 1 1 16 1 1 16 2 1 16 4 1 Chapter 1: Product Overview Chapter 1: Product Overview • Elevated Ambient Temperature: If installed in a closed rack assembly, the operation temperature of the rack environment may be greater than room ambient. Use care not to exceed the rated maximum ambient temperature of the appliance. • 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 connection of the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Consider equipment nameplate ratings for maximum current. • Reliable Earthing: Reliable earthing of rack mounted equipment should be maintained. Pay particular attention to supply connections other than direct connections to the branch circuit (for example, use of power strips). DSR Inst...
