Line cards can be installed in slots in the card cage. As each line card powers on,
a power-on self-test (POST) is performed on the line card memory. A full set of
field diagnostics can also be run on a line card from the system console providing
a pass/fail message both in the line card alphanumeric LED display and on the
system console.
Check the following to help isolate a problem with the line cards:
Are both banks of alphanumeric LED displays on?
•
The two displays are powered separately. The left display receives power
–
from the DC-DC converter on the line card. The right display is powered
directly from the power supply. So, even if the line card has not powered
up, the right display could be on. If both displays are off, the line card
might not be fully plugged into the backplane connector, there might be
a problem with the MBus module on the line card, or the system power
supply may be off.
If both displays are on, check the message being displayed. As soon as
–
the DC-DC converter is turned on by the MBus module, the processor on
the line card begins the boot process. Status messages are displayed in the
alphanumeric displays as the boot process continues on the line card.
