NT24k Series Common Features
The NT24k are modular managed switches designed for factory automation, utilities, security surveillance,
SCADA and other industrial applications.
The versatile N-Tron® NT24k Managed Industrial Ethernet Switches feature connectivity for up to 24
Gigabit (16 for the NT24k-DR16) ports and offer a wide range of connectivity options—including 100Base,
Gigabit, fiber optic and copper options—in rugged Rack Mount or DIN-rail enclosures. Designed to handle
the most demanding environments, the NT24k Switches deliver wire-speed throughput and include
expanded shock and vibration tolerances, extreme operating temperature range and two or three slots to
accommodate mix-and-match port modules. N-Ring™ technology restores network communication within
~30ms of fault detection. Robust remote monitoring capabilities make management easy.

Please make sure the NT24k Ethernet Switch package contains the following items:
1. NT24k Switch
2. Product CD
Contact your carrier if any items are damaged.
Installation
Read the following warning before beginning the installation:
WARNING
Never install or work on electrical equipment or cabling during periods of lightning activity. Never connect
or disconnect power when hazardous gasses are present.
Disconnect the power cable before removing any enclosure panel.
UNPACKING
Remove all the equipment from the packaging, and store the packaging in a safe place. File any damage
claims with the carrier.
CLEANING
Clean only with a damp cloth.
RACK AND PANEL MOUNTING
The NT24k comes configured with standard rack mount brackets which may be used to mount our
products to standard 19" racks. As an alternative we offer our NT24k Panel Mount Assembly (P/N:
NT24k-PM) which may be used to securely mount the NT24k products to a panel or other flat surface.
A clearance of 1 inch should be observed on the sides, back, top and bottom to allow proper ventilation.
Also a cable bend radius of 4 inches should be observed for the front and back side of the unit.

APPLYING POWER AND FAULT CONNECTIONS (Back View)
All NT24k can operate with one power supply, either AC or DC. The Rack Mount NT24k can accept up to
two power supply units. Each power supply can be AC or DC. Each low voltage DC Power supply includes
redundancy (two DC supplies).
The example below is shown from the back and includes a AC Power supply on the left and a DC
power supply on the right, looking from the back:
NT24k with DC Power Supply Installed:
Unscrew & Remove the DC Voltage Input
Plug from the Power Input Header
Install the DC Power Cables into the Plug
(observing polarity).
Plug the Voltage Input Plug back into the
Power Input Header.
Tightening torque for the terminal block
power plug is 0.5 Nm/0.368 Pound Foot.
Verify the Power LED stays ON.
Notes:
When a DC Power supply is installed, only one power supply must be connected to power for
minimal operation. For redundant power operation, V1and V2inputs must be connected to separate
DC Voltage sources. This device will draw current from both sources simultaneously. Use 16-28
gauge wire when connecting to the power supply.
Recommended 24V DC Power Supplies, similar to: N-Tron’s P/N NTPS-24-1.5
Input AC 115/230V
Output DC 24-28V
Output Current 1.5A @ 24V
