LOCATION
As with any electrical device, the OSD2154P should be placed where the unit will not be subjected to
extreme temperatures, humidity, or electromagnetic interference. Specifically, the site selected should
meet the following requirements:
The ambient temperature should be between -20°C to 75°C (-4°F to 167°F).
•
The relative humidity should be less than 95 percent, non-condensing.
•
Surrounding electrical devices should not exceed the electromagnetic field (RFC) standards.
•
Make sure that the switch receives adequate ventilation. Do not block or obstruct the
•
ventilation holes on any side of the switch.

FIXED RJ45 COPPER PORT PIN ASSIGNMENTS
The OSD2154P complies with IEEE802.3af, IEEE802.3at and PoE++, and is capable of supplying up
to 60W of PoE per RJ45 port. The OSD2154P supports Alternative A & B (pins 1/2, 3/6, 4/5, 7/8). For
PoE++ the OSD2154P transmits power over all 8 pins. Bidirectional data as well as power terminate on
all 8 pins. Both or either ports can optionally support dual signature PD. Port 3 (see Figure 2) on the
rear panel supports High-PoE output (see Table 5).
Figure 6 shows the pin configuration for the fixed RJ45 copper port.
