Step #2 Selftest
•
After the DRAM tests a set of selftest diagnostics run. The selftest diagnostics only affect the LEDs if
there is a failure. On failure, the Power LED changes from solid green to solid yellow (and remains
that way as long as the unit is powered on, or the selftests are run again and pass).
•
Additionally, the first four Port Status LEDs are temporarily lit with a code indicating the last selftest
failure. The pattern is a binary number indicating the kind of failure. Table 6-1, shown below,
provides information on the port failure patterns including a short description and required action.
Note: If there are multiple failures you will only see the pattern for the last failure (refer to the System
Status LED chart on page 144, for more information).
•
The error code will remain on the Port Status LEDs until the runtime image is entered (when these
LEDs are cleared so they can show Port Status). The Power LED will remain "Yellow" (indicating a
failure) instead of "Green".
Note: The selftest diagnostic results for the DSP can be viewed at anytime from the MI using the following
path: Status->System->HW Diagnostics

Step #3 ROM Countdown
After the diagnostics run, the ROM goes through a short countdown on the console. During this time the
WAN1 LED flickers green. The WAN1 LED goes solid green and the WAN2 LED flickers green while the
runtime image is being loaded into memory. WAN2 goes solid green when the runtime image is
successfully loaded into memory. Control is then passed to the runtime image (see Step #4).
Step #4 Runtime Image
The runtime image first turns all system status and Port Status LEDs off, except for the Power LED (which
is solid green if there are no self-test failures, or solid yellow if there are self-test failures).
During initialization the runtime image flickers Port Status LED1 while it's downloading the Programmable
Logic Device (PLD), and then makes Port LED1 solid once the PLD download is complete. Similar
flickering and solid LED patterns are used when downloading each Digital Signal Processor (DSP), where
Port LED2 is the signaling DSP, and Port LED8 is the voice DSP. So when the runtime image is starting
up you see each Port LED 1 through 8 successively flicker and go solid until all eight are solid.
After the PLD and DSP downloads are complete, the Port LEDs drop into their normal operating patterns.
