SECTION 2

PREPARATION FOR USE

INSTALLATION

When the VM4016 is unpacked from its shipping carton, the contents should include the

following items:

One VM4016 VXIbus module

One VM4016 Analog Comparator Module User’s Manual (this manual)

All components should be immediately inspected for damage upon receipt of the unit.

Once the VM4016 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 VM4016. Once the

chassis is found be adequate, the VM4016’s logical address and the chassis’ backplane jumpers

should be configured prior to the VM4016’s installation.

CALCULATING SYSTEM POWER AND COOLING REQUIREMENTS

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

may 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 would also void the warranty of

the module.
