Alert Led; Recovering From Corrupted Software - 3Com OfficeConnect User Manual

6 Re-apply power to the Router, and when the start-up sequence
has completed, browse to:
http://192.168.1.1
and run the configuration wizard. You may need to restart your
computer before you attempt this.
7 When the configuration wizard has completed, you may
reconnect your network as it was before.

Alert LED

When the Router is first powered on, the Alert LED will be on for
between three and five seconds, and then start to flash while the
system software checks the hardware for proper operation. The
Alert LED may continue to flash for one minute or longer,
depending on your network configuration. Once the Router has
started normal operation, the Alert LED will go out.
If the Alert LED does not go out following start up, but
illuminates continuously, this indicates that the software has
detected a possible fault with the hardware. If the Alert LED is
flashing slowly this indicates a firmware failure. Remove
power from the Router, wait 10 seconds and then re-apply
power. If the Alert LED comes on continuously again, then a
fault has been detected, refer to "Recovering from Corrupted
Software" below. If this does not fix the problem, contact
your supplier for further advice.
During normal operation, you may notice the Alert LED
lighting briefly from time to time. This indicates that the
Router has detected a hacker attack from the Internet and
has prevented it from harming your network. You need take
no specific action on this, unless you decide that these attacks
are happening frequently in which case you may wish to
discuss this with your ISP. The Router logs such attacks, and
this information is available through the configuration screens.

Recovering from Corrupted Software

If the Alert LED flashes slowly on and off following power-up, it
is possible that the system software has become corrupted. In
this condition, the Router will enter a fail-safe state; DHCP is
disabled, and the LAN IP address is set to 192.168.1.1. Follow
the instructions below to upload a new copy of the system
software to a Router unit in this state.
Ensure that one of your computers has a copy of the new
software image file stored on its hard disk. If not contact 3Com

1 Remove power from the Router and disconnect the Cable/DSL
