System description
The Phontech 7200, 24 PoE Ethernet GBit Switch has 2 internal power supplies. One serves as the main power source
and the other as a back up power source. There are 2 power input configurations, AC/AC and AC/DC. The unit also
includes a built-in power supply voltage measurement circuit for monitoring purposes. The measurements are
available both on the web and CLI interface.
For best power reduction results the Phontech 7200, 24 PoE Ethernet GBit Switch should be implemented with an
EEE 802.3az power saving option, which automatically turns off the port when there is low to no traffic utilization.
This unit supports IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) on all 24 gigabit Ethernet (GbE) ports. The PoE system
is capable of delivering up to 150 watts of power. The delivered power is managed and monitored per each port.
There are 3 modes for configuring power reservation by the ports (PDs):
1.
Power allocation per port.
2. Power according to class.
3. Power reserved by exchanging PoE information using Link Layer Discovery Protocol (LLDP) protocol.
The system description of the Phontech 7200, 24 PoE Ethernet GBit Switch includes details regarding each of the
