LEDs
Check the PWR LED on the front of the network extender. If the LED is
OFF, indicating that the network extender is not receiving power, do the
following:
❑ If the network extender is inserted in the AT-MCR12 chassis, make
sure that the power cord is securely connected to the power
source and to the power connector on the back panel of the
AT-MCR12 chassis.
❑ If the network extender stands alone, make sure that the provided
adapter is securely connected to the power source and to the
power connector on the back panel of the network extender.
❑ Verify that the power outlet has power by connecting another
device to it.
❑ Try connecting the network extender to another power source.
❑ Try using a different power cord or a different power adapter.
❑ Check that the voltage from the power source is within the
required levels for your region.
Verify that the ACT LED for each twisted pair port is ON. If a ACT LED is
OFF, do the following:
❑ Verify that the end node connected to the port is powered ON and
is operating properly.
❑ Check that the twisted pair cable is securely connected to the port
on the network extender and to the port on the end node.
❑ Make sure that the twisted pair cable does not exceed 100 meters
(328 feet).
❑ Verify that you are using the appropriate category of twisted pair
cable: Category 3 or better for 10 Mbps operation, Category 5 and
Category 5E for 100 Mbps operation.
❑ Make sure that the operating parameters of the port on the
network extender are compatible with the end node to which the
port is connected.
