*Power wiring
The PSE-SW5B44DB is IEE802.3bt PoE switch, for PoE operation, make sure your power supply
could offer over 70W for 4x 802.3af PoE ports, or over 140W for 4x802.3at PoE ports, or over
360W for 4x 802.3bt PoE ports. For 802.3af operation, the input voltage range must in 44V to
57VDC. For 802.3at or 802.3bt type 3 operation, the input voltage range must in 50V to 57VDC. For
802.3bt type 4 operation, the input voltage range must in 53V to 57VDC.
The PoE switch PSE-SW5B44DB allow powered by another PoE source on port 5 (UPLINK) as a
PoE repeater or extender. From port 5 (UPLINK) input can get up to 71W (802.3bt Type 4 PD).
If powered via port 5 (UPLINK), Port 1~4 can get 16.8W per port. If only connected to 2 ports,
then there can be 35W per port.
If powered via the rear terminal, please make sure the input current is not over 10A. If powered on
port 5, make sure the input current is not over 2Amp.
Ports 1~4 will deliver DC power over the Ethernet cable as detailed below:
* Data pair A plus V- on line 1 and 2
* Data pair B plus V+ on line 3 and 6
* Data pair C plus V+ on line 4 and 5
* Data pair D plus V- on line 7 and 8
Port 5 may get DC power over the Ethernet cable, as detailed below:
* Data pair A plus V+ /V- on line 1 and 2
* Data pair B plus V-/V+ on line 3 and 6
* Data pair C plus V+/V- on line 4 and 5
* Data pair D plus V-/V+ on line 7 and 8
The terminal block on the rear panel should be wired as detailed below:
The power input Vin1 supply power to PoE port 1&2, power input Vin2 supply power to PoE port
3&4.
