How can I update a SmartNode 4552/4554 in redboot mode ?
Hold down the reset button while you power cycle the unit and make sure you hold it down for at least 10 seconds. Connect a PC to the WAN port of the SN4554. You will have to set your PC statically to an IP address on the same subnet (172.16.40.2 255.255.0.0). The WAN interface IP address in reboot mode should be 172.16.40.1 255.255.0.0. You will then have to open a telnet session to the above IP address. Once there you should see the RedBoot> prompt. Follow these instructions to reset back to factory. 1. RedBoot> fis load 2.
