After all diagnostic tests are completed on a line card, a PASSED or TEST
FAILURE message appears on the console.
• If the line card passes, the Cisco IOS software image on the line card is
automatically reloaded (unless the
wait keyword is specified).
•
If the line card fails, the Cisco IOS software image on the line card is not
automatically reloaded.
If the line card fails the test, the line card is defective and must be replaced. Under
certain circumstances, TAC engineers may direct you to replace field-replaceable
memory modules and then retest. For example, if the DRAM test fails, you might
only need to replace the DRAM on the line card. However, this should only be
performed under the guidance of a TAC engineer and only when observing tightly
controlled static-sensitive device handling procedures.
dl-timeout-plus
<1-2000
seconds >
(Optional) Manipulates the download timeout value for
users with slow TFTP boot paths.
300 seconds is the baseline value. Any value from 1 to 2000
adds that value to 300. For example, a
dl-timeout-plus
value of 12 makes the total value 312 seconds.
update-fpga (Optional) Updates flash memory with FPGA images from
the current field diagnostics download image.
This option limits the field diagnostics session to one task;
updating the FPGA images in flash memory on the line
card. No other testing is performed during this session.
This process is non-selective in cases where a line card
contains multiple FPGA images.
Caution Do not unplug the line card or terminate the field
diagnostics session during an FPGA upgrade.
