Powering The Reader - Nordic ID SAMPO S2 User Manual

1.8. POWERING THE READER

Nordic ID Sampo S2 can be powered via DC power supply (sold separately) or ethernet port if the network
supports power over Ethernet (PoE) feature or PoE injector is being used. Regardless of what powering
method is used, the data communication can be handled via USB connection or if IP connectivity is
required then via WWAN, WLAN or ethernet. Nordic ID Sampo S2 powers up automatically when
connected to DC power supply or PoE.
The rated maximum power consumptions for Nordic ID Sampo S2 reader are:
• Powered via 802.3af PoE: 12W
• Powered via DC power supply (sold separately): 20W (12-24V DC)
NOTE! WLAN and 3G are disabled If the reader is powered via the PoE. 802.3af PoE can't
provide enough power to the reader to keep WLAN and 3G features working as expected.
