    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.
