Installing the Switch 408
Installation Procedures
When the switch is powered on, it performs its diagnostic self
test. The self test takes approximately 3 seconds to complete.
LED Behavior:
During the self test:
• All the switch and port LEDs are on.
When the self test completes successfully:
• The Power LED stays on and the Fault LED goes off.
• The port LEDs (Link/Act, FDx, and 100) go into their normal
operational mode.
If the LED display is different than what is described above,
especially if the Fault LED stays on for more than 5 seconds, the
self test has not completed correctly. Refer to chapter 3, “Trou-
bleshooting” for diagnostic help.
