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:
3. Change your baud rate to 115200 bps, and press Enter to enable download
mode. From the terminal emulation program, select the file you want to
download, set the protocol to XModem, and then initialize downloading.
Notes: 1. If you use Windows HyperTerminal, disconnect and reconnect to
enable the new baud rate.
2. The download file should be an OmniStack
®
6148 binary file from Alcatel;
otherwise the agent will not accept it. The file naming convention is:
Runtime program: Agent-Vx.yz,
POST program: Boot-Vx.yx, and
Mainboard program: 8051-Vx.yz
