Upgrading Firmware via the Serial Port
You can upgrade system firmware by connecting your computer to the
serial port on the switch, and using a console interface package that
supports the XModem protocol. (See “Required Connections” on page
1-2.)
1. Restart the system by using the Restart System command or resetting
the power by pulling out the power cord, waiting five seconds, and
plugging it back in.
2. When the system initialization screen appears as shown below, press
“D” to download system firmware, and then indicate the code type (1:
Runtime, 2: POST, 3: Mainboard).
For example, if you select 1 (for downloading agent firmware), the system
will display the following message:
