The USB interface is designed for the connection to the "X5" – external ETH/USB adapter. The "X5"
is an optional accessory to RipEX, for more see Section 5.3, “Connecting RipEX to a programming
PC”. The adapter is used for service access to RipEX’s web configuration interface.
The USB connector also provides power supply (5 V/ 0.5 A). It can be used to temporarily power a
connected device, for instance a telephone. The USB connector should not be used as permanent
source of power supply.
4.2.6. Reset button
Fig. 4.11: Reset
RipEX’s bottom-side enclosure includes a reset button accessible through
an opening. When this button is pressed, the STATUS diode on the LED
panel goes dark (indicating that the button has been pressed). If you hold
the button for 5 seconds, the STATUS diode starts flashing slowly indicat-
ing that the reset is complete. If you continue to hold the button for 15 or
more seconds (the STATUS diode starts flashing quickly) and then release
it, you will reset the device’s access information to default: parameters
such as the
login, password
and
ethernet IP
will be reset to their defaults.
Resetting access parameters to defaults also sets the Ethernet speed to
„Auto“ and results in clearing all
firewall
rules (which may have been
blocking the access by accident). Remember to re-install your firewall if you are using one.
Note
To reset the RipEX only use the RESET button as described above or use the button in RipEX’s web
configuration, see
Adv. Conf., Maintenance
. Never use a power cycling (disconnecting and reconnecting
power supply) to reset it. While power cycle resets, or rather reboots the RipEX, its software will not
terminate correctly resulting in logs, statistics and graphs not being saved properly.
