Configuring Equipment Racks
The VSU-2000 can be placed on a desktop, shelf, or mounted in a standard
19-inch equipment rack. The location of the unit and the layout of your
equipment rack or wiring room are extremely important for proper system
operation. Equipment placed too close together, inadequate ventilation, and
inaccessible panels can cause system malfunctions and shutdowns, as well as
make system maintenance difficult.
The following information will help you plan an acceptable equipment rack
configuration.
• Enclosed racks must have adequate ventilation. Ensure that the rack is not
overly congested because each unit generates heat. An enclosed rack should
have louvered sides and a fan to provide cooling air.
•
When mounting a chassis in an open rack, ensure that the rack frame does not
block the ventilation grates. If the chassis is installed on slides, check the
position of the chassis when it is seated all the way into the rack.
•
In an enclosed rack with a ventilation fan in the top, excessive heat generated
by equipment near the bottom of the rack can be drawn upward and into the
ventilation grates of the equipment above it in the rack. Ensure that you
provide adequate ventilation for equipment at the bottom of the rack.
Instructions for rack mounting are provided in the section “Rackmount
Installation” on page 2-1.
