NS-1G48 Overview and Use Cases

What Is the NS-1G48?

The OREI NS-1G48 is a 48-port Gigabit PoE network switch with 6x 10G SFP+ uplink ports, housed in a 1U 19-inch rackmount metal chassis. It is designed for high-performance, scalable network deployments in medium to large environments — including enterprise AV systems, surveillance installations, large office networks, and multi-zone AV over IP setups. With a 216Gbps switching capacity and full line-speed forwarding, it delivers smooth, stable data transmission across all connected devices even under heavy loads.

The NS-1G48 supports Power over Ethernet (PoE) on all 48 RJ45 ports, with a total PoE power budget of 850W and up to 30W per port. This allows compatible devices such as IP cameras, wireless access points, VoIP phones, and AV over IP encoders and decoders to be powered directly through the Ethernet cable — no separate power adapters required at the device end. The NS-1G48 is specifically designed to work with OREI's ToVi X1, X2, and X4 series of AV over IP products. A built-in web management interface provides centralized network monitoring and configuration.

IMPORTANT — PoE Powers Connected Devices Over the Network Cable

The NS-1G48 delivers both network data and electrical power over standard Ethernet cables (IEEE 802.3af/at PoE). This means compatible devices such as IP cameras, wireless APs, and ToVi AV over IP encoders/decoders can be powered directly through the RJ45 cable connection — no separate power supply needed at the device end.

The total PoE power budget across all 48 ports is 850W. If you plan to connect many high-draw devices, ensure the combined power draw of all connected PoE devices does not exceed this budget.

IMPORTANT — Non-PoE Devices Are Also Supported

The NS-1G48's PoE ports are adaptive. Standard (non-PoE) Ethernet devices such as computers, NAS units, or non-PoE switches can be connected to any of the 48 RJ45 ports without any issues. The switch automatically detects whether a connected device requires PoE and only delivers power to devices that request it.

IMPORTANT — SFP+ Ports Are for Uplink Use Only

The 6x SFP+ ports (ports 49-54) are 10G uplink ports intended for connecting the NS-1G48 to a core switch, router, or other network infrastructure — not for directly connecting end-user devices. SFP+ transceivers (fiber or copper) are required and are not included.

Step-by-Step Setup

• Place the switch on a flat surface using the included rubber feet, or mount it in a standard 19-inch EIA rack using the included mounting ears and screws. Ensure there is adequate ventilation around the unit — do not stack heavy objects on top of it.
• Connect the included AC power cord to the power port on the rear panel, then press the power switch to turn on the unit. The PWR LED on the front panel will light up.
• Connect your network devices (IP cameras, wireless APs, ToVi encoders/decoders, computers, etc.) to the PoE ports (1-48) using standard Cat5e or Cat6 Ethernet cables. PoE-capable devices will be powered automatically.
• Connect the SFP+ uplink ports (49-54) to your core switch, router, or fiber infrastructure using compatible SFP+ transceivers and cables as needed.
• For basic plug-and-play use, no further configuration is required. The switch will forward traffic automatically.
• To access the web management interface, connect a PC to any port on the switch. Set the PC's IP address to the same subnet as the switch (e.g., 192.168.0.x). Then open a web browser and navigate to the switch's default IP address: 192.168.0.1.
• Log in with the default credentials (Username: admin, Password: admin) to access network configuration, VLAN settings, PoE management, port monitoring, and more.

Web Management Interface

The NS-1G48 includes a built-in web-based management interface accessible from any standard web browser. It allows you to monitor port status, configure VLANs, manage PoE settings per port, view traffic statistics, set up DHCP, and perform firmware updates.

Default login credentials:

• IP Address: 192.168.0.1
• Username: admin
• Password: admin

It is recommended to change the default password after first login to secure your network.

What Devices Is the NS-1G48 Compatible With?

The NS-1G48 is compatible with any device that uses a standard Ethernet (RJ45) connection, including:

• OREI ToVi X1, X2, and X4 series AV over IP encoders and decoders
• IP cameras and NVRs
• Wireless access points
• VoIP phones
• Computers, laptops, and servers
• NAS devices and other network storage
• Other managed or unmanaged network switches (via uplink)

For PoE-powered devices, the connected device must comply with IEEE 802.3af (up to 15.4W) or IEEE 802.3at (up to 30W) standards. Non-PoE devices work on any port without any configuration change.

Frequently Asked Questions

Q: What is the OREI NS-1G48 used for?

A: The NS-1G48 is a 48-port Gigabit PoE managed network switch designed for connecting and powering large numbers of network devices such as IP cameras, wireless access points, and AV over IP equipment. It is specifically optimized for use with OREI's ToVi X1, X2, and X4 series products.

Q: How many devices can I connect?

A: Up to 48 devices via the RJ45 PoE ports, plus additional uplink connections via the 6x SFP+ ports.

Q: What is the difference between the NS-1G48 and the NS-1G24?

A: The NS-1G48 has 48 PoE ports (vs. 24 on the NS-1G24), 6x SFP+ uplink ports (vs. 4), and an 850W total PoE power budget (vs. 420W). It is designed for larger deployments that require more device connections and higher total PoE capacity.

Q: Can I use the NS-1G48 with non-PoE devices?

A: Yes. The PoE ports are fully adaptive and work with both PoE and standard non-PoE Ethernet devices. The switch only delivers power to devices that request it.

Q: What is the total PoE power budget?

A: The switch has a total PoE power budget of 850W across all 48 ports, with a maximum of 30W per port. If the combined draw of all connected PoE devices approaches this limit, lower-priority ports may have their power reduced or disabled. Monitor usage via the web interface.

Q: Is the NS-1G48 rack-mountable?

A: Yes. It uses a standard 1U 19-inch metal chassis and includes mounting ears and screws for rack installation. It can also be used as a desktop switch using the included rubber feet.

Q: Do I need to install any software to use it?

A: No software installation is required for basic plug-and-play use. The web management interface is accessed directly through a browser using the switch's IP address.

Q: How do I access the web management interface?

A: Connect a PC to any port on the switch, set the PC's IP address to the same subnet (e.g., 192.168.0.x), then open a browser and navigate to 192.168.0.1. Log in with the default credentials (admin / admin).

Q: The switch does not power on — what should I check?

A: Verify the power cord is securely connected to both the switch and the wall outlet. Try a different power outlet if needed. Check that the PWR LED on the front panel is lit. If the unit still does not power on, contact OREI support.

Q: A connected device is not receiving PoE power — what should I check?

A: Confirm the device is IEEE 802.3af/at PoE-compatible. Check that the total PoE power draw across all ports does not exceed 850W. Try connecting the device to a different PoE port. Review the PoE status in the web management interface to check for port shutdowns or budget overruns.
