Out-of-band Operations
ATM network administrators can upgrade CPSW microcode (but not media modules) using an out-of-band
operation with an RS-232 plug. To do this, you must attach a workstation with an emulated VT100
protocol to the CPSW module.
After locating the directory where the microcode updates are stored, use the workstation as the CPSW
console. Log on using the administrator password and enter the following commands:
1. MAINTAIN (to activate Maintenance mode)
2. DOWNLOAD OUT_OF_BAND (to specify boot or operational code and to load it in the flash EEPROM
of the CPSW module).
Start the file transfer in the workstation using the Xmodem protocol. The transfer takes approximately
6 minutes for the boot code, 22 minutes for the operational code, at 9600 bps (the time is halved if the
transfer is done at 19200 bps).
If you enter DOWNLOAD OUT_OF_BAND BOOT, you automatically quit Maintenance mode and
activate the new BOOT microcode.
3. BOOT (to restore normal operation), if you did not enter DOWNLOAD OUT_OF_BAND BOOT in Step
2.
