Configuring the Switch 63
Other Configuration Requirements
The following is required for downloading embedded software and configuring the device:
• ASCII terminal (or emulation) connected to the serial port (cross-cable) in the front of the
unit
• Assigned IP address for the switch for device remote control use with Telnet, SSH, and so
forth
NOTE: The configuration process defines only one port.
Booting the Switch
When the power is turned on with the local terminal already connected, the switch goes through
Power On Self Test (POST). POST runs every time the device is initialized and checks hardware
components to determine if the device is fully operational before completely booting.
If a critical problem is detected, the program flow 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.
To boot the switch, perform the following steps:
1
Ensure that the ASCII cable is connected to the terminal.
2
Connect the power supply to the switch.
3
Power on the switch.
As the switch boots, the bootup test first counts the device memory availability and then
continues to boot. The following screen is an example of the displayed POST:
Boot1 Checksum Test...............................PASS
Boot2 Checksum Test...............................PASS
Flash Image Validation Test.......................PASS
Testing CPU PCI Bus Device Configuration..........PASS
BOOT Version 1.0.0.13 Date 13-Aug-2003 Time 15:28:31
Autoboot in 2 seconds - press RETURN or Esc. to abort and enter
prom.
The boot process runs approximately 30 seconds.
The auto-boot message that appears at the end of POST (see the last lines) indicates that no
problems were encountered during boot.
