2.2.2.3 Powering the module
In general any external power supply which is providing the specified input voltage (see
Technical Data chapter) can be used to power the module.
An external 12V
DC
power supply is recommended and is provided with an ANET1553
module. All onboard voltages are generated from this voltage.
Power Up behaviour:
- when applying external power for the first time, the module will start up w/o
requiring an explicit power button press.
- as long as the external power supply is present, the module can powered down
(shutdown) and powered up via pressing the power button.
- Interrupting the external power or pressing the power button longer than
3 seconds, will force a power off without shutdown (power down) of the OS.
Note: It is recommended, but not mandatory, to shutdown (power down) the module
via the power button or the ANET web front (‘maintenance’ page) end or SSH
shell command (‘power off’ as user ‘root’) to avoid any user data corruption,
especially when having customer applications/scripts active on the module.
