NSTALLATION
When the VM1548C is unpacked from its shipping carton, the contents should include the
following items:
(1) VM1548C VXIbus module
(1) VM1548C Open Collector Digital I/O Module User’s Manual (this manual)
All components should be immediately inspected for damage upon receipt of the unit.
Once the VM1548C is assessed to be in good condition, it may be installed into an appropriate
C-size or D-size VXIbus chassis in any slot other than slot 0. The chassis should be checked to
ensure that it is capable of providing adequate power and cooling for the VM1548C. Once the
chassis is found to be adequate, the VM1548C’s logical address and the chassis’ backplane
jumpers should be configured prior to the VM1548C’s installation.

The power and cooling requirements of the VM4018 are given in the Specifications section of
Section 1 in this manual. It is imperative that the chassis provide adequate power and cooling for
this module. Referring to the chassis User’s Manual, confirm that the power budget for the system
(the chassis and all modules installed therein) is not exceeded and that the cooling system can
provide adequate airflow at the specified backpressure.
It should be noted that if the chassis cannot provide adequate power to the module, the instrument
might not perform to specification or possibly not operate at all. In addition, if adequate cooling is
not provided, the reliability of the instrument will be jeopardized and permanent damage may
occur. Damage found to have occurred due to inadequate cooling will void the warranty on the
instrument in question.
