APPENDIX B

UPGRADING FIRMWARE VIA

THE SERIAL PORT

The switch contains three firmware components that can be upgraded; the loader code, diagnostics (or Boot-ROM) code, and runtime operation code. The runtime code can be upgraded via the switch’s RS-232 serial console port, via a network connection to a TFTP server, or using SNMP management software. The loader code and diagnostics code can be upgraded only via the switch’s RS-232 serial console port.

Note: You can use the switch’s web interface to download runtime code via TFTP. Downloading large runtime code files via TFTP is normally much faster than downloading via the switch’s serial port.

You can upgrade switch firmware by connecting a PC directly to the serial Console port on the switch’s front panel and using VT100 terminal emulation software that supports the XModem protocol. (See “Required Connections” on page 2-2.)

1.Connect a PC to the switch’s Console port using a null-modem or crossover RS-232 cable with a female DB-9 connector.

2.Configure the terminal emulation software’s communication parameters to 9600 baud, 8 data bits, 1 stop bit, no parity, and set flow control to none.

3.Power cycle the switch.

4.When the switch initialization screen appears, enter firmware-download mode by pressing <Ctrl><u> immediately after
