A circuit card’s components include CMOS chips that are sensitive to
static electricity. Before touching a card first touch a grounded metal
object, such as any unpainted surface on the matrix, to dissipate static
electricity.When handling a card, be careful not to bend any of the
card’s connector pins or component leads.
Store spare cards in electrically insulated packaging such as anti-static
heavy duty plastic bags or in unused port card slots in the matrix.
HOT PATCHING
Analog port and expansion circuit cards are “hot patchable” and “self
initializing”, meaning that a faulty card can be removed and replaced
while the system is powered, having no effect on any part of the
system operation, except to the analog port card’s assigned sixteen
ports.
Communication to a card’s connected remote devices will be
interrupted when that card is removed from the matrix. When the card
is replaced, communication is restored.
ANALOG PORT NUMBERING
Each MVX-A16 interface has circuitry to support 16 ports. A grid
printed on the matrix’s rear panel gives the numbering scheme for the
ports, as shown in Figure 7-4.
