Power-On Self-Test
After you connect the DSU/CSU to a power source, the unit performs the power-on
self-test to ensure that it is in good working order. The DSU/CSU performs this test
on itself upon power-on or after a device reset, unless it has been disabled by the
Self-Test configuration option (see
Appendix C,
Configuration Options
).
The self-test includes a basic processor test, a limited memory test, a code
checksum test, and basic verification tests of the internal components. The front
panel LCD displays the progress and pass/fail status of these power-on tests.
Procedure
The power-on self-test consists of the following steps:
1. Once the DSU/CSU is plugged in, the In Progress screen appears and the Fail
LED blinks ON and Off continuously.
2. All the LEDs then start to flash simultaneously in the pattern twice ON, then
Off. Then, the LCD begins to flash characters and numbers in the same
pattern, alternating with the flashing LEDs.
3. If the self-test is successful, the Passed screen appears for one second, the
Fail LED turns Off and the OK LED lights.
