My trial to upgrade to SVN 570 fails. Unlike the previous version, all green light signal of TEL, WAN and SYS are off after the new firmware is uploaded. Only PWR light is on.
From HyperTerminal screen, I note that a numuber of modules fail to load and install with errors. Hence, network cannot be detected.
Also, I cannot access the back-end system via Putty and WinSCP. Fortunately, HyperTerminal is still function and I can manage to restore the SVN 506M. |
