Configurable Alarm Contact
The alarm contact located on the top of the NT24k compact series, can be used to control an external warning device
based on an event. The current carrying capacity is 1A at 24VDC. It is normally open and the relay closes when a fault
condition occurs, though this can be reversed via configuration. These pins can be used to connect an external warning
device such as a light in order to provide an external alarm. The conditions for generating a fault condition (closing the
relay) can be configured through software.
Refer to the NT24k Software User’s Guide for more information.

Connecting the Unit
For 10/100/1000/T(x) ports, plug a Category 5E twisted pair
cable into the RJ45 connector. Connect the other end to the
far end station. Verify that the LNK LEDs are ON once the
connection has been completed. To connect any port to
another device, use a standard CAT5E straight through or
crossover cable with a minimum length of one meter and a
maximum length of 100 meters.
Red Lion recommends the use of pre-manufactured CAT5E
cables to ensure the best performance. If this is not an option
and users must terminate their own ends on the CAT5E
cables; one of the two color coded standards shown to the
right should be utilized. If a user does not follow one of these
standards then the performance and maximum cable
distance will be reduced significantly, and may prevent the switch from establishing a link.
For FX/FXE/GX/GXE units, remove the dust cap from the fiber optic connectors and connect the fiber optic cables. The TX
port on the FX/FXE/GX/GXE models should be connected to the RX port of the far end station. The RX port on the FX/FXE/
GX/GXE versions should be connected to the TX port of the far end station.
Warning:
Creating a network loop without employing a network path protocol such as N-Ring, N-Link, or RSTP is an illegal
operation that can create a network storm which will crash the network.
