1. Retry the command at 1-minute intervals up to 3 times.
1 FAIL Either Reference A failed or CI card A failed. This condition usually indicates a
failure of the DS1 reference; however, there may also be a failure of the CI card
to which the reference is connected. The system technician dispatched to
investigate this problem should take a spare CI card in case the CI card caused
the failure. If you are NOT ON-SITE, use the following procedure:
1. Look for DS1-BD (DS1 Interface Circuit Pack) errors using the display
2. If there are no DS1-BD errors or after resolving every DS1-BD error, issue

If you are ON-SITE, use the following procedure:
1. Look for a red LED on CI card A (i.e., the left CI card). If there is a red
