3 Console -- 1K Xmodem update firmware

The 24 + 2 Giga SNMP Ethernet Switch provides the ability to perform a 1k X modem firmware update feature from the RS-232 console port. 1K X modem only works in 57600bps mode. So you must change the default baud rate to 57600bps to download the firmware image.

There are 2 situations where the 1k X modem update feature can be used:

a.The Administrator enters "1K X modem receiver mode" by pressing any key within 5 seconds after system is powered on.

b.The system automatically enters "1K X modem receiver mode" if it detects a firmware checksum failure while booting.

1.When you initially start the “1K X modem mode” from one of the 2 options above, press the disconnect button. (You need to disconnect, as the connection is currently 9600bps, not 57600bps)

Select File -> Properties, and change the baud-rate to 57600bps, then press OK.

2.Press the connected icon, you will see “CCCC…”displayed on the console. Then select Transfer, Send File.
