Power Up

This section provides instructions on how to power up
your system. See Chapter 3 and Chapter 5 for

Power-up Diagnostics

The Switch 3900 system runs diagnostic software at
power up. This software verifies that the system
works before you add it to the network.
If any component fails during power-up diagnostics,
the system either fails to power up or keeps faulty
ports off-line. To verify if any ports have failed
diagnostics, look at the system configuration display
in the Switch 3900 Administration Console.
To view messages that are displayed in the
Administration Console during power-up diagnostics,
connect a terminal, workstation, or PC that has
terminal emulation to the system's Console port.
During power up, the system status LEDs provide
information on components in the Switch 3900
system. The system and port status LEDs and the
information that they provide are shown in Figure 14.
