◆ PoE power supply is impossible.
■ Power is not supplied to a Powered Device.
● If you use an STP cable, PoE power supply may not be possible depending
on the installation environment. In such cases, use a UTP cable.
● Is a CAT5e or better straight cable (RJ45-8/8) used?
●
Is the cable connected to the port 1 to 16 that supports PoE power supply?
●
Ensure that either the port alone or the entire equipment is not over
-
loaded.
● Is the Powered Device connected to the port compliant with the
IEEE802.3at (30W) standard?
■ Port LED (right) is blinking orange:
● Ensure that the total power supply demand from PoE-powered devices
does not exceed 185 W.
■ When the power supply is suddenly shut off
● It is likely that a PoE-powered device in use has a different power consump
-
tion in normal operation and standby states. After turning on the PoE LED
(power supply mode), confirm that a single port is not overloaded [the Port
LED (left) is not blinking orange] and that the maximum limit of the total
power supply is not exceeded (the PoE LIM. LED is not blinking orange).
