VX1410A & VX1420A IntelliFrame Mainframe Instruction Manual
The IntelliFrame Mainframe provides optimal cooling for all installed modules.
The mainframe uses an intelligent, adaptive cooling scheme to efficiently remove
heat while maintaining quiet operation. The mainframe monitors the temperature
rise of the exhaust air above each module slot and automatically adjusts the fan
speed to keep the temperature rise to user specified temperature rise or less for
the each module. You can also manually set the fan to full speed to provide
maximum cooling.
Air is exhausted at the sides of the mainframe, allowing you to stack the
mainframe with other rackmount equipment. You don’t have to worry about
restricting airflow out of the top of the mainframe or creating a chimney effect.
Cooling is not wasted on empty slots. IntelliGuides automatically direct air to
only those slots containing modules; empty slots are shut off. The mainframe
directs airflow across each installed module from the bottom to the top of each
slot. Baffles balance the airflow from the front to back and across occupied slots
in the mainframe.
You can remove the air filter from the rear of the mainframe. The fans can be
replaced without disassembling the entire mainframe.
The VX1420A Super Cooler has all the features of the VX1410A IntelliFrame
Mainframe, but with higher cooling capacity and very quiet operation. The
higher cooling fan operates at a low fan speed with equivalent airflow.
The IntelliFrame Mainframe has an auto configuration, solid-state backplane that
uses electronic jumpering of the IACK and BUS GRANT signal lines. There are
no jumpers to move or install on the backplane. This results in a high quality
backplane that is ideal for ATE systems that must be reconfigured frequently.
The EMI DIN shields are standard to provide superior EMI protection.
Full differential distribution of the CLK10 signals provides a clean timing source
for your VXIbus instruments.
You can order the IntelliFrame Mainframe with user-installed rackmounts and
cable trays. The cable trays provide a means to conveniently route cables from
the front of the modules to the rear of the mainframe. Options 1U and 2U cable
tray depths range from 1.75 to 6.0 inches. Install Option 1U to provide a
1.75-inch, 2.5-inch, or 4.25-inch deep cable tray. You can install Option 2U to
provide a 3.5-inch, 4.25-inch, or 6.0-inch deep cable tray.
The rackmount adapters let you recess the mainframe from the front panel
mounting surface at specified depths from 0.735 inches to 5.735 inches in
0.5-inch increments. Similarly, you can configure the mainframe to extend out of
the front of the rack at specified depths (0.57 inches to 5.57 inches in 0.5-inch
increments).
