D.6.12 Link Card Operating in Wrong Mode
The downlink card is receiving packets over the management link, but the format of
the data indicates the uplink card (boat link card) is functioning as a downlink card
(server link card). A reserved pin in a boat link card slot is used by the link card to
determine if the card is installed in the boat or in a host system.
D.6.12.1

Cause

Location signal failure in a link card or boat.
■
D.6.12.2

Resolution

Swap the boat link card. If the problem is resolved, the link card was faulty.
■
If the problem still exists, swap the boat to see if the problem is resolved.

D.6.13

Can't Read ManR FRUID Data

The service processor examines the static FRUID to read part number, serial number,
and dash number. If attempts to decode the FRUID data fail, errors are generated.
Any of the FRUs can cause this problem.
The centerplane in the I/O Box has three FRUID SEEPROMs. SEEPROM=0 and
SEEPROM=1 are on the nonshared side of the DEMUX and are only used to
determine I/O Box information. SEEPROM=2 is the shared device containing
dynamic FRUID data on the centerplane.
Note – For this error, the fault is isolated to a single FRU, but attempts to update
FRUID fault status will fail, so the failure is posted as Ext sensor instead of Ext
FRU.
D.6.13.1 Cause
FRUID not programmed.
■
D.6.13.2 Resolution
Replace the faulty FRU.
