1.6 System overview

1.6.1 Power supply and additional equipment
There is one LAN interface and one DC power input on the EXPLORER 540.
Note
Depending on your configuration, you may have to use a PoE switch or a PoE injector
connected to the LAN interface or a battery connected to the DC input in order to
provide power to the EXPLORER 540.
Note
For examples, see M2M application examples on page 2-12. You may also need to
provide a switch to be able to accommodate more than one LAN connection, e.g. for
local access to the web interface during installation or service.
1.6.2 M2M overview, example
In the example below, the M2M system has a built-in PoE switch, providing the power
to the EXPLORER 540 together with the M2M communication through the LAN
interface.

The EXPLORER 540 works as a Powered Device (PD). This means it may be
powered by PoE, but it does not supply PoE.
If you are using a cellular modem, you cannot use PoE to power the system.
Use the DC input instead.
