2.3 Connecting to Power
Step 1: Connect the supplied AC power cord to the receptacle
on the back of the switch, and then plug it into a
standard AC outlet with a voltage range from 100 to
240 Vac.
Step 2: Disconnect the power cord if you want to shut down
the switch.
POWER-ON SELF TEST (POST)
The Switch performs its Power-On Self Test (POST) when the
power is switched on. During the POST, the switch CPU will:
l
perform a series of diagnostic procedures to make sure the
basic system is functioning integrity
l
decompress the main switching software runtime image from
the flash ROM into DRAM area
l
begin executing the main switching software
A command line prompts when you press the Esc key on a
terminal connected to the switch serial port during the POST
process. Then you can execute the following options:
DOWNLOAD RUNTIME SOFTWARE FROM SERIAL PORT
This will download the runtime system image to the switch via
the serial port. Before selecting this option, make sure:
l
A host system is running a terminal emulation program that
supports the Kermit file transfer protocol.
l
The host system’s hard drive has the required binary file that
will be downloaded to the switch.
