Each plug-in card is equipped with a red diagnostic indication LED on the front side,
near the top of the card. This LED can assume one of three states of illumination: OFF,
ON, or FLASHING. The illumination state of the LED indicates the card's operating
condition.
Table 10-1
lists the indication provided by each of the three LED states.
During normal operation, the card diagnostic LED should be extinguished. However,
the LED routinely illuminates steadily whenever power is first applied to the system,
the entire system is initializing, or the card is first inserted into a card slot. The LED
remains illuminated steadily until the card receives a card database from the system.
LED Constantly Lit
If the LED stays lit for more than two or three minutes, a problem may exist within the
card. The most likely problem is a conflict with the system database, although it also
may be an actual malfunction of the card circuitry.
Table 10-1 Card
Diagnostic LED
Indications
The system database will prevent a card from initializing:
„
When the card is inserted into a card slot that has been initialized with another
card type.
Check the Card List branch (Route: CLIS) in the database, to determine whether
the card slot has been previously initialized with a different card type. If the
STATUS field shows CARD REPLACED, and the I_TYPE for the card slot shows a
different card type, enter NO_CARD to clear the slot.
„
There are insufficient system resources allocated in the System Sizes Definition to
support the new card. The STATUS field in the Card List branch (Route: CLIS)
shows NO RESOURCES. Check the Sizes branch (Route: SIZ) in the database to
determine the maximum number of ports of the type provided by the problematic
card, and then determine how many of these ports are already installed. If the
additional ports provided by the new card exceed the maximum number allocated
in Sizes, the card cannot initialize.
This situation can be rectified only through restructuring the memory allocation of
the system. Initializing the database and reprogramming the system restructures
the memory allocation.
