8/24-port GbE L2 Nebula Cloud Managed PoE Switch

The Zyxel Nebula NSW100 Series Cloud Managed Switches provide Layer-2 Gigabit access switching with 8/24-port PoE and non-PoE models. The PoE models support 802.3at PoE Plus standards to provide a 180/375-watt highpower budget. Every Nebula switch is designed to be managed completely from the Nebula Control Center. The cloud-based management interface provides site-wide configuration and monitoring of all ports, which allows multiple switches to be configured at the same time with a single click over the Web.

The Nebula switches bring many benefits of the cloud management systems, such as simplified configuration, easy management, site-wide visibility and real-time control for speedy branch network deployments into networks. Advanced settings such as user friendly ACL, VLAN-based QoS and PoE scheduling significantly improve the efficiency of network management.

  • Essential L2 features with user-friendly ACL and VLAN configuration
  • Optimized for quality voice and video traffic with high 375 (28P)/180 (10P)-watt power budget PoE technology
  • Support Port Mirroring for network traffic monitoring
  • Support DHCP Server Guard and IGMP snooping
  • RADIUS, static MAC forwarding and 802.1X authentication


Zero-touch deployments

The Zyxel Nebula Cloud Managed Switches support plug-and-play installation through remote provision with simple steps. Every Nebula Switch automatically downloads the current network configuration to the device and enables auto-provisioning without the need for on-site network professionals.

Efficient network provisioning

Rather than traditional management operations that require network administrators to configure each device separately with repetitive command lines, all Nebula Switches connected to the Nebula Control Center can be centrally managed with a single management interface. For better network management efficiency, switch settings made in the Nebula Control Center can automatically propagate to all connected Nebula switches.

Increased network uptime

User misspecifications are commonly seen in setting up ACL, reconfiguring VLAN/IP or other similar operations, and these may cause interruption to cloud connection. The Zyxel Nebula Cloud Managed Switches provide stable network environments by incorporating a mechanism that detects and prevents configuration that could potentially cause network disconnection between the switch and Nebula Control Center.

Better user experience

Quality-of-service (QoS) functionality is essential for applications that require guaranteed quality for stable connections. The Zyxel Nebula PoE switches offer a smarter way for optimizing quality of service, which enables administrators to specify VLAN configuration with different priorities directly. This means that administrators can assign a priority to a specific VLAN through Nebula Control Center, and this priority can be applied to all tagged traffics for a specific VLAN. Traffics of the higher priority VLAN will receive preferential treatment and are serviced before VLANs with lower priorities. The same mechanism applies to voice VLAN configuration as well.

Holistic management

Zyxel Nebula Switches can automatically discover wired and wireless devices that connected to a network, and then draw the network topology to enable network administrators to easily troubleshoot issues remotely without the need for manual mapping and overlay monitoring software.

Ultra Durable Hardware Design

Unlike normal switch hardware design with Electrolytic capacitors (E-cap), the Zyxel Nebula Cloud Managed Switches adopt solid capacitors to get rid of drying out, bursting and leaking problems. Solid capacitors ensure Nebula switches with longer lifetime, high stability and robust operation.
