8 Upgrading Firmware
The ECN330-switch contains three firmware components that can be upgraded;
the diagnostics (or Boot-ROM) code, runtime operation code and the loader
code. For more information, see section 5.1 on page 35. The diagnostics and
the loader code can be upgraded only through the ECN330’s RS-232 serial
console port.
Note: The runtime software is upgraded through PEM. Please refer to the
PEM User's Guide for details.
ECN330-switch firmware can be upgraded by connecting a PC directly to the
serial Console port on the ECN330’s front panel and using VT100 terminal
emulation software that supports the XModem protocol. (See section 5.2.2 on
page 38.)
1. Connect a PC to the ECN330’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 ECN330.
4. When the ECN330-switch initialization screen appears, enter firmware-
download mode by pressing <Ctrl+u> immediately after power on or
rebooting the ECN330-switch.
5. Type mercury at the password prompt. Screen text similar to that shown in
Figure 239 on page 1168 is displayed:
