Connecting Powered Devices (PDs)
Note that this device does not comply with IEEE 802.3at at 48‐51.4 VDC, or with IEE 802.3bt at 48‐53.4 VDC.
This device drops ~1.3V from Vin to PSEout. IEEE requires these PSEout voltages at the PSE output into the
cable:
• 802.3af: 44VDC
• 802.3at: 50VDC
• 802.3bt: 52VDC
Not meeting this PSEout requirement may cause power up failures or power cycling with devices drawing
maximum power with maximum cable loss.
Power
can be from either of the two power sources (AC input or DC input) or site source DC. Note that DC
power is required for PoE operation.
Connecting to AC Power
1. Connect the AC power cord to the AC power receptacle of switch.
2. Connect the other end of the AC power cord to the AC power outlet.
3. Check the SYS LED. If it is ON, the power connection is correct.
