8 DSR Switch Installer/User Guide
• One USB2 or USB2L DSRIQ module per target server for virtual media sessions
• (Optional) DSView 3 software
• (Optional) V.34, V.90 or V.92-compatible modem and cables
• (Optional) power control device(s)
Setting up your network
The DSR switching system uses IP addresses to uniquely identify the switch and the target devices.
The DSR switch family supports both Dynamic Host Configuration Protocol (DHCP) and static IP
addressing. Avocent recommends that IP addresses be reserved for each switch and that they
remain static while the switches are connected to the network.
For additional information on setting up the DSR switch using the DSView 3 software, and for
information on how the DSR switch uses TCP/IP, see the DSView 3 Installer/User Guide.
Rack Mounting a DSR Switch
A rack mounting kit is supplied with each DSR switch. You may either place the DSR switch on
the rack shelf or mount the switch directly into an Electronic Industries Alliance (EIA)
standard
rack.
Most DSR switches may be rack mounted in a 1U configuration. The DSR switch family does not
support a 0U configuration.
Rack mounting safety considerations
• Rack Loading - Overloading or uneven loading of racks may result in shelf or rack failure,
causing damage to equipment and possible personal injury. Stabilize racks in a permanent
location before loading begins. Mount components beginning at the bottom of the rack, then
work to the top. Do not exceed your rack load rating.
• Power Considerations - Connect only to the power source specified on the unit. When multiple
electrical components are installed in a rack, ensure that the total component power ratings do
not exceed circuit capabilities. Overloaded power sources and extension cords present fire and
shock hazards.
• 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: Install the equipment in the rack so that the amount of airflow required for
safe operation of the equipment is not compromised.
• Reliable Earthing: Maintain reliable earthing of rack mounted equipment. Pay particular
attention to supply connections other than direct connections to the branch circuit (for
example, use of power strips).
