ICB status LED indicator

The ICB has a red LED indicator at the top of the faceplate that indicates
the status of the card. If the LED is lit, the card can be faulty or manual
busy (Man). The card goes through a series of tests. When inserted into
the slot or reset, the card:
•
•
•
•
This procedure takes approximately 45 seconds. If the card turns on and
remains on without blinking, the card is not functioning correctly. The LED
turns off when the card returns to service.

Power Up Self-test

The ICB card has testability features that aid in fault isolation. When
inserted into an operating system module, when it is powered up, or when
the system is reset, each ICB card automatically performs a Power Up
Self-test. A Power Up Self-test can be performed on a card using software
commands or menus.
The self-test checks general ICB functions and determines if they are
operating correctly. The checks are useful when first installing the cards,
because the card automatically starts the self-test when inserted. The
self-test provides an immediate indication of the card's operating status by
performing a detailed test and analysis of the installed hardware. The test
determines the integrity of the hardware and establishes the connection
of the ICB card.
The Power Up Self-test is executed through the maintenance port. If any
fault has been detected, an error message is stored in the system log file
and is printed on the maintenance port.
