POWER SUPPLY CONNECTIONS
IMPORTANT! There are two options available for the OSD2184P: The OSD2184P and OSD2184PW.
The Table below (Table 4) indicates the power requirements for each. They both require external DC
power which is connected via the 2-way terminal block located on the front panel as shown in Figure 5.
CAUTION
It is highly recommended to wait about 30 seconds before reconnecting the PD
after the PD has been disconnected from the unit. This will prevent a high inrush
current being applied to the unit. Although the OSD2184P/PW has a high inrush
current tolerance (400mA for 50 to 75ms as per the IEEE802.3at standard), inrush
currents higher than 1.5A may damage the device.
