Note
If you have stacked your switches, refer to the “Powering Considerations”
section on page 3-15 for more information.
Note
If you are connecting the switch to a Cisco redundant power system (RPS), refer
to the documentation that shipped with your RPS.
As the switch powers on, it begins the power-on self-test (POST), a series of tests
that runs automatically to ensure that the switch functions properly. POST lasts
approximately 1 minute.
When the switch begins POST, the System, the RPS, the Master, the Status, the
Duplex, the Speed, and the Stack LEDs turn green. (On the Catalyst 3750-24PS
and 3750-48PS switches, the Power over Ethernet [PoE] LED also turns green as
POST begins.) The System LED flashes green, and the other LEDs remain
continuous green.
When POST completes successfully, the System LED remains green. The RPS
LED remains green for some time and then returns to its operating status. The
other LEDs turn off and return to their operating status. When POST fails, the
System LED turns amber. If POST fails, see
Chapter 4, “Troubleshooting,” to
determine a course of action.
After you have powered all the switches in the stack, a switch is elected as the
stack master. The master LED is green on the stack master switch.
If you started the terminal emulation program before you powered on your switch,
the PC or terminal displays the bootloader sequence. You need to press
Enter to
display the setup program prompt.
