LinkCard Hardware Problems
If a LinkCard hardware problem exists, complete the following procedure:
1. Remove the computer’s cover if it is not already removed.
2. Start Status Cue for Windows.
3. Observe the LinkCard’s LEDs. Refer to Figure A.2 for location information
• LED1: +12 volts to console: When "on" this LED indicates that +12 volts is being
sent to the console through fuse F8. An "off" LED indicates that F8 may be blown.
This LED will only be on if it is the master LinkCard. The power to this LED is
supplied through the pigtail from the computer power supply.
• LED2: +5 volts to console: When "on" this LED indicates that +5 volts is being
sent to the console through fuse F7. An "off" LED indicates that F7 may be blown.
This LED will only be on if it is the master LinkCard. The power to this LED is
supplied through the pigtail from the computer power supply.
• LED3: +5 volts to LinkCard: When "on" this LED indicates that +5 volts is
present on the LinkCard from the computer’s mother board. An "off" LED
indicates no +5 volts power to the LinkCard.
• LED4: This LED (heartbeat) indicates the status of the LinkCard by flashing at the
following rates:
• Flashing at a 1 hertz rate – Status Cue has found the LinkCard, boot code is
running, and communication is transpiring (Status Cue for Windows is not
running).
• Latching on one time and flashing at an inverted 1 hertz rate (pulsing) –
Status Cue has found the LinkCard, but the checksums in the LinkCard do not
match the checksum in
statusq.ini
(Status Cue for Windows is running).
This will instigate the LinkCard upload procedures.
• Flashing Rapidly – Status Cue has found the LinkCard and the LinkCard is
running system code (Status Cue for Windows is running). This is normal
operation.
• Flashing mostly on – There is an IRQ conflict between the LinkCard and
another system device or option card. Refer to "Conflict Between Option Cards
and Computer Components" on page A-7.
• Flashing mostly off – There is a base memory conflict between LinkCard and
another system device or option card. Refer to "Conflict Between Option Cards
and Computer Components" on page A-7.
• LED 4 – Multiple LinkCards: it takes a few seconds per LinkCard for
synchronization to occur. Once the LinkCards are synchronized, each LED 4 will
blink in sync.
