the values should match. If the value does not match, two failing cards are identified, the one driving the test value and the one receiving the test value, as it is impossible to determine which of the two cards has the failing bus connection.
testing output or input cards
The test can have two results. One is success. The other is failure, along with a list of one or more cards that failed. This result is accessible to the host through the compositor protocol. The result is also available without the host. A successful test puts the cards into normal operation. If the test fails, the speaker on the compositor sounds a long,
testing controller cards
This procedure does not do any specific test of the controller card backplane connections. Being a single connector, and having a position that is the same for all configurations, it is believed that failure of the card upon installation is unlikely. In the event there is a bent pin or a poorly seated controller card, it is likely that the controller card will not function at all, since it controls the power switch and the processor that can test the other cards. Although very unlikely, it is possible that an input or output card that fails the test may actually be a failure of one of the pins on the controller card.
The test procedure depends of a few of the bus connections in order to detect that a card is present in a slot. If one of these critical signals is shorted or open, the test may miss a failure by not knowing that a card is even in the slot, or the test may misidentify a card.
