The mainframe is inspected mechanically and electrically
before shipment. It should be free of marks or scratches and
should meet or exceed all electrical specifications. To confirm
this, inspect the mainframe for physical damage incurred
during transit. Retain the mainframe packaging if reshipment
is necessary.
Cleaning procedures consist of exterior and interior cleaning
of the mainframe and cleaning fan filters. Refer to your module
user documentation for information on cleaning the individual
VXIbus modules.
Always power off the mainframe and disconnect
the power cord before cleaning or servicing the
mainframe.
Use a dry, low-velocity stream of air to clean the interior of the
mainframe. Use a soft-bristle brush for cleaning around
components. If you must use a liquid for minor interior
cleaning, use a 75% isopropyl alcohol solution and rinse with
deionized water.
Clean the exterior surfaces of the mainframe with a dry lint-
free cloth or a soft-bristle brush. If any dirt remains, wipe with
a cloth moistened in a mild soap solution. Remove any soap
residue by wiping with a cloth moistened with clear water. Do
not use abrasive compounds on any part of the mainframe.
Avoid getting moisture inside the mainframe
during exterior cleaning - use just enough
moisture to dampen the cloth.
Do not wash the front or rear panel connectors or
switches. Cover these components while cleaning
the mainframe.
Do not use chemical cleaning agents; they may
damage the mainframe.
contain benzene, toluene, xylene, acetone, or
