(B) Reboot:
Press the “Reboot Now” button to reboot the device. All
your settings will be preserved.
From fi rmware 2.8.4 and higher an auto reboot option in case of times-
tamp off set has been added.
Very seldomly and only for the following scenario, an off set on the
hardware timestamp may occur.
When the GigaCore is used with PTPv2 or AVB (gPTP) enabled on fi ber
ports (Not applicable for copper ports), and if only a small fraction of
a packet did already arrive on the fi ber port, when the port was dis-
connected. In that particular event the hardware timestamping may
be off set.
GigaCore measures this off set at disconnection and checks if it is faulty.
In the rare case it is indeed considered faulty, the only way to recover
from this off set is to restart the switch and thus reset the fi ber PHYs to
eliminate the off set. This is needed to have a synchronized system. Via
the utilities web page of the
GigaCore, the user can now choose to reboot automatically if this (Out-
OfSync symptom) occurs. By default, the auto reboot is disabled.
If the off set occurs on the fi ber port, the port mode LED will blink RED
to indicate the problem. A message will also be displayed in Araneo
and the web UI of the GigaCore (E).
If the user does not opt for automatic reboot of the switch, then the
aff ected fi ber link will automatically get a diff erent path cost in case it
concerns a designated port. This means that the link will not be your
primary link in case you have a redundant path available (example: ring
connection).
In case the switch does reboot, a persistent reboot reason will be
logged into the switch.
