POWER SUPPLY CONNECTIONS
The OSD2153P requires external DC power. The voltage range of the OSD2153P is +46V
DC
to
+57V
DC
@ 6W. >52V
DC
is recommended for PoE+ (30W) and
≥
55V
DC
for PoE++ (60W) operation.
Power is connected to the 2-way terminal block located on the front panel as indicated in Table 2.

FIXED RJ45 COPPER PORT PIN ASSIGNMENTS
The OSD2153P complies with IEEE802.3af, IEEE802.3at and PoE++, and is capable of supplying up
to 60W of PoE. The OSD2153P supports Mode A (i.e. transmitting power over pins 1, 2, 3, & 6) and
Mode B (i.e. transmitting power over pins 4, 5, 7, & 8). For PoE++ the OSD2153P transmits power
over all 8 pins. Bidirectional data as well as power terminate on all 8 pins.
Figure 6 shows the pin configuration for the fixed RJ45 copper port.
