10.2.2 The STATUS LED
The STATUS LED indicates the health of the device and sync status.
Ø
LED Static
If the LED is lit and static, then either the device is booting or there is an internal problem:
Static LED

Color (not white)
Ø
LED Blinking
If the LED is blinking at regular intervals, then the device is working properly and the LED indicates the sync
status.
Note that if the LED is blinking from white to a color, then this indicates that Power Core is running as a PTP
Master. The table below describes the possible states:
Blinking LED
Blue <-> Off
Yellow <-> Off
Red <-> Off
Green <-> Off
Magenta <-> Off
Red <-> white
Green <-> white

10.2.3 Replacing Defective Parts
All rear panel IO cards are hot-pluggable which means that they can be exchanged during uptime. This allows
fast replacement of a card in the case of a hardware failure. Providing the card is of the same type and fitted to
the same rear panel slot as the faulty card, the new card will immediately take over the same functions.
Other components can be serviced by removing the top cover of the Power Core frame. You must disconnect
the unit from its power source to perform these operations.
Do NOT remove the cover while the device is powered.
For more information on these procedures, please contact your local Lawo representative or email
support@lawo.com.
