Upgrading Firmware Via The Serial Port - SMC Networks SMC6724L3 Management Manual

U
PGRADING
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
