Transition Networks 25025-NA 24-Port Gigabit Unmanaged Switch
Overview
The Transition Networks 25025-NA is a 24-port Gigabit unmanaged switch designed for straightforward network distribution in small to mid-scale security, access control, and warehouse automation installations. With 24 Gigabit Ethernet ports, the switch delivers plug-and-play connectivity without requiring configuration or management interfaces — meaning no VLAN setup, no spanning tree tuning, no firmware updates. It simply passes traffic at wire speed across all 24 ports simultaneously. This makes it ideal for integrators who need reliable, predictable distribution without the complexity overhead that managed switches introduce.
Key Features
- 24 × 1 Gbps Ethernet Ports: Each port supports full-duplex Gigabit throughput, so multiple IP cameras, access control readers, or door controllers can transmit simultaneously without port saturation. Typical 24-camera deployments (running 4–8 Mbps per camera) will consume only 15–25% of available bandwidth, leaving headroom for retransmissions and PoE handshake overhead.
- Unmanaged Architecture: No learning curve, no configuration menus, no compatibility matrix with your VMS. Plug in power and Ethernet cables and it forwards frames. This reduces deployment time and eliminates a class of operational issues — no misconfigured QoS, no accidental VLAN mismatches.
- 15W Power Consumption (12VDC 1.25A input): The 25025-NA draws minimal power, so it won't stress facility distribution or create thermal load in tight cabinet spaces. The input accepts 100–240VAC, meaning standard wall outlets or UPS-backed distribution can power it without special conditioning or step-down transformers.
- Global Voltage Input (100–240VAC): Single unit works across North American, European, and Asian facility wiring standards. Valuable in multi-site integrations or when hardware is shipped between regions without reconfiguration.
- Compact Form Factor: Designed to fit standard network cabinet spaces without dominating vertical real estate. Suitable for wall-mount or DIN-rail installation in electrical rooms and control cabinets alongside access control panels and power distribution equipment.
- Passive Cooling (No Fans): Fanless design means no acoustic noise in quiet control rooms, no filter maintenance, and no mechanical failure mode. 24-port unmanaged switches generate minimal heat — all traffic forwarding happens in silicon with no CPU bottleneck.
Integration & Compatibility
The 25025-NA integrates into any existing Gigabit infrastructure with no prerequisites. It works with network video recorders, IP cameras from any ONVIF-compliant manufacturer, access control systems, and standard IT switches. Because it is unmanaged, there is no concept of VLAN isolation or port mirroring — all ports see all traffic, which is appropriate for small- to mid-scale deployments where security segmentation is handled at the router or firewall layer instead.
If you are deploying a single-building system with fewer than 48 cameras and minimal inter-system communication, the 25025-NA provides all the switching capacity you need. If your design calls for QoS prioritization (e.g., emergency door-unlock traffic ahead of routine camera streams), or if you need VLAN segmentation to isolate camera traffic from IT networks, consider a managed switch instead.
Deployment Scenarios
Warehouse Automation & Security Integration: Combine the 25025-NA with access control readers, overhead IP cameras, and motion sensors in a single cabinet. The unmanaged design means the integrator focuses on cabling and PoE power delivery, not switch configuration. One device handles all local Ethernet distribution.
Multi-Building Campus: Deploy one 25025-NA per building, each connected to a central managed core switch. The unmanaged unit acts as a local distribution hub, eliminating single points of failure at the edge and simplifying troubleshooting — if one building loses network, the others remain unaffected.
Frequently Asked Questions
Q: Does the 25025-NA support PoE power delivery?
A: No. The 25025-NA is a passive switch — it forwards Ethernet frames only and does not inject power into any port. You will need a separate PoE injector or PoE switch to power IP cameras and other PoE devices. If you need integrated PoE on all 24 ports, consider a managed PoE switch from the Transition Networks line.
Q: What happens if I connect two 25025-NA units together in a ring topology for redundancy?
A: Unmanaged switches forward broadcast frames continuously; without spanning tree or loop detection, the ring creates a broadcast storm and network lockup. Do not chain unmanaged switches in loops. Connect them in a tree (one upstream, others downstream) or use a managed switch at the core with automatic loop detection.
Q: Is the 25025-NA fanless, and how does it handle heat in a sealed cabinet?
A: Yes, the unit is passively cooled with no moving parts. 24-port unmanaged switches generate minimal heat because switching happens in silicon, not a CPU. Typical operating temperature remains well below 60°C in cabinet environments with standard ventilation. No active cooling is required.
Q: Can I wall-mount the 25025-NA, or does it require a cabinet?
A: The compact form factor allows wall or shelf mounting. Verify cable routing (Ethernet runs in and out, power inlet) and ensure the mounting surface is stable. The unit itself weighs less than 1 lb.
Q: Does the 25025-NA require any configuration or firmware updates?
A: No. Unmanaged switches have no configuration interface, no CLI, no web UI. Power it on and it begins forwarding frames immediately. Firmware updates are not applicable — the forwarding logic is fixed in silicon.
Q: What is the warranty on the 25025-NA?
A: Refer to the manufacturer documentation or contact the supplier. Transition Networks typically offers a 1-year limited warranty on unmanaged switches from the point of purchase.

The Transition Networks 25025-NA is the right choice when you need straightforward port expansion without the operational burden of a managed switch. I deploy it regularly in single-building security integrations where simplicity and reliability matter more than advanced traffic control. The 24 Gigabit ports handle typical multi-camera loads with ease, and the 15W power footprint means it fits cleanly into battery-backed cabinet distribution without consuming scarce UPS capacity.
Technical Highlights:
- Unmanaged Forwarding at Wire Speed: All 24 ports simultaneously move Gigabit traffic without CPU bottleneck or configuration overhead. A 24-camera system running 4–8 Mbps per stream uses only 20% of total bandwidth, leaving headroom for retransmissions and network redundancy.
- Global 100–240VAC Input: Single power supply works across facility voltage standards. No step-down transformer needed. The 1.25A draw at 12VDC is minimal — standard 18W industrial supplies will power the 25025-NA with capacity to spare for auxiliary devices.
- Fanless, Passive Cooling: No moving parts means no noise, no filter maintenance, no mechanical failure mode. Unmanaged 24-port silicon generates negligible heat even in full-load scenarios.
Deployment Considerations:
- No PoE Injection: The 25025-NA does not supply power on any port. Pair it with a separate PoE switch or injector block. If you need integrated PoE across all 24 ports, plan for a managed or PoE-capable unit instead.
- No Loop Detection: Do not chain multiple unmanaged switches in a ring. Broadcast storms will lock the network. Use a tree topology or deploy a managed switch at the core with spanning tree enabled.
Deploy the 25025-NA as the local distribution hub in warehouse automation facilities, access control cabinets, or small-to-mid-scale single-building security systems where uptime and simplicity outweigh the need for QoS or VLAN isolation. Pair it with external PoE delivery, run standard Cat5e or Cat6 cabling from cameras and readers, and you have a reliable, zero-configuration foundation that requires no ongoing tuning.
