Installation 2–9
2.2 Running the DECserver 90M Self-Tests
The DECserver 90M runs a series of self-tests when you turn on the power and re-
ports test status through the DECserver 90M LEDs (refer to Figure 1–1).
If the DECserver 90M is not properly connected to an Ethernet LAN (refer to Section
2.1), the network loopback self-tests fail.
The following list describes the status of the LEDs during self-test.
•
Initially, all LEDs go on briefly, then go off, leaving only the power LED on.
•
The Port Activity LEDs go on one-by-one and remain on, as the DECserver
90M completes each segment of self-test. All eight LEDs are on once the
tests have run successfully.
•
After successful completion of the self-tests, the System OK LED is on and
the eight port LEDs go off.
To reset the DECserver 90M to the factory-default settings, press the Reset switch
after port 7 LED goes on, but before port 4 LED goes on during self-test. Keep the
Reset switch depressed until the Network OK and System OK LEDs flash rapidly.
This indicates that the DECserver 90M has been reset to the factory settings.
NOTE
If a self-test pattern halts, an error condition has been
detected (refer to Chapter 3).
