8. Power Requirements
A.
Standard input power to the TC3301's is 12VDC @600mA.
B.
The TC3301's power connectors are two terminal blocks located on the rear panel of the unit. Polarity
is indicated under each connector block (see Figure 2).
C.
Should an external power adapter need to be replaced, use one with the following specifications: 12VDC
@600mA. You may order it directly from TC Communications.
D.
The TC3301 can also be ordered with an optional 24VDC, 48VDC, 125VDC or 115/230VAC with an
external power cube.

+5V Voltage indicator.
This LED should light whenever power
is connected to the unit. It indicates the
correct operating voltage is being derived
from the power source.
Full Duplex LED indicator:
Solidly lit, when Ethernet signal
is in 1000M full duplex mode.
Link LED indicator:
Solidly lit, when the twisted pair port has
established a valid link.
Optic transmitter and receiver
Fiber Optic Link Status LED:
Lit while receiving an optical
signal at the optical receiver (Rx).
Power A & Power B LEDs: The power source can be redundant:
both Power A and Power B share the load. If either
power source fails, the other one takes over full load.

Activity LED indicator:
Lit when there is Ethernet activity
detected through the RJ-45 port.
Note: As the Ethernet activity going through
the RJ-45 port becomes greater, this LED
will become brighter.
1000M LED indicator:
This LED will always be lit
since the media converter
operates at a fixed 1000Mbps.
