Appendix B: Troubleshooting
1. The device connected to POE-151S cannot be powered?
Answer:
a. Please check the POE-151S is connect with an IEEE
802.3af complied in-line device like POE-150, and check
if the POE LED indicator at POE-151S is steady blink
once attach to the IEEE 802.3af in-line power device.
Then connect the DC plug cable to the device you would
like to power on.
b. Please check the cable type of the connection from one
end to the other end. The cable should be an 8-wire UTP,
Category 5 or above, EIA568 cable within 100 meters. A
cable with only 4-wire, short loop or over 100 meters, all
will affect the power supply.
c. Please check the power requirement of the device you
would like to power and check the label of the POE-151S
if it meets the requirement. There are three models of
POE-151S for different power output, DC 5V, DC 9 V and
DC 12V.
d. Please check the specification of the powered device. If
the device is over the specification of POE-151S, the LED
indicator of POE-151S will blink instead of stead green.
The maximum currents that POE-151S can supply are:
2A (5V DC), 1.3A (9V DC) and 1A (12V DC).
2. The device can only work at 100Mbps through it is connected to
Gigabit Ethernet device?
Answer:
POE-151S will use 4-wire for data transmission (pair 1,
2, pair 3, 6) and 4-wire for power supply (pair 4, 5, pair
7, 8), thus Gigabit Ethernet device connect to POE-151S
will not send data over the power wire and the transmit
speed shall change to 100Mbps.
