Out-of-band Operations
ATM network administrators can upgrade 6416SW microcode (but not ATM 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 6416SW module.
After locating the directory where the microcode updates are stored, use the workstation
as the 6416SW 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 6416SW 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.
