data continues to flow via the Category 5, 6 or 6e cabling regardless of the status of the end
device.
Prior to connecting end devices to the 3300 In-Line Power Unit, determine if:
1. The end device is "Power over LAN Enabled" or not. If the end device is not "Power over
LAN Enabled", the end device may be safely connected. However, the port will supply no
power and will function as a normal Ethernet data port.
2. The end device's power requirements are consistent with the 3300 In-Line Power Unit
voltage and power ratings.
To connect end devices to the 3300 In-Line Power Unit:
1. Connect a Category 5, 6, or 6e cable to the end device directly (if the device is "Power
over LAN Enabled").
2. Connect the opposite end of the same cable to the RJ-45 wall outlet.
3. On the front panel of the 3300 In-Line Power Unit, monitor the response of the correspond-
ing port LEDs. If the "Power Active" LED lights up, the 3300 In-Line Power Unit has
identified your end device as a "Power over LAN Enabled" device and the port is sending
power.
Install the 3300 In-Line Power Adapter
The Mitel Networks 3300 Phone Power adapter (p/n 57003121) is required to enable certain
Mitel Networks IP Phones to be powered from the Mitel Networks 3300 In-Line Power Unit p/n

To install the In-Line Power Adapter:
1. Connect the RJ-45 output (male end) of the power adapter to the IP Phone network
connector located on the underside of the telephone.
2. Connect the LAN cable (male end) to the power dongle RJ-45 input (female end).
The Power Unit, sensing the Power Adapter, will apply -48VDC across pins 4,5 and 7,8 spare
pair LAN cable to power the IP Phone.
