Booting the Switch
After the local terminal is connected, turn on power. The switch then goes
through power-on self-test (POST). POST runs every time the switch is
started and checks hardware components, to determine if the switch is
operational before completely booting. If the system detects a critical
problem, the boot process stops. If POST passes successfully, a valid
executable image is loaded into RAM. POST messages are displayed on the
terminal and indicate test success or failure.
The boot process runs for approximately 40-45seconds.
When the boot process completes, the following LEDs are lit, as shown in
Figure 7-2:
•Power
• Status
• Fan (should be green)
• RPS (if it is being used)
