Upgrading Firmware via the Serial Port

The switch contains two firmware compon ents that can be upgraded; the

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 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 1-2.)

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><f> immed iately after

the diagnostic test results. Screen text similar to that shown below

displays:
