This chapter covers the suggested inspection, preparation considerations and
background information necessary prior to using the V5C. Unpacking, initial
inspection, and first-time operation of the V5C are also covered. Following the
procedures given in this chapter is recommended, since these will verify proper
operation, both after shipping and before the product is integrated into your
VMEbus system.
Proper handling of the V5C is critical to ensure proper operation and long-term
reliability. When unpacking the board, and whenever handling it thereafter, be
sure to hold the V5C by the front panel or the card ejectors as shown in the
drawing on the left. Do not hold the V5C by the circuit card edges, the heat
sink, or the VMEbus connectors.
The discharge of static electricity, known as
E
lectro
S

ischarge or ESD, is
a major cause of electronic component failure. The V5C has been packaged in a
static-safe bag which protects the board from ESD while the board is in the bag.
Before removing the V5C or any other electronic product from its static-safe
bag, be prepared to handle it in a static-safe environment.
You should wear a properly-functioning antistatic strap and ensure you are fully
grounded. Any surface upon which you place the unprotected V5C should be
static-safe, usually facilitated by the use of antistatic mats. From the time the
board is removed from the antistatic bag until it is in its card cage and functioning
properly, extreme care should be taken to avoid “zapping” the board with ESD.
You should be aware that you could “zap” the board without your knowing it; a
small discharge, imperceptible to the eye and touch, can often be enough to
damage electronic components. Extra caution should be taken in cold and dry
weather when static easily builds up.
