User Manual
FAQ
How many devices can this switch power simultaneously with PoE?
The switch features 24 PoE+ ports with a total budget of 370 watts. This allows simultaneous power delivery to multiple devices such as IP phones, wireless access points, and security cameras. Each PoE+ port can deliver up to 25.5 watts, enabling support for power-hungry devices like PTZ cameras or multi-radio access points across the available port count.
What types of SFP modules are compatible with this switch?
The four dedicated SFP (mini-GBIC) slots support standard SFP modules for both copper and fiber connections. You can use 1000Base-SX, 1000Base-LX, or 1000Base-T SFP modules to connect to fiber optic networks or extended copper runs. The slots are not shared with Ethernet ports, providing full flexibility for uplink configurations without sacrificing PoE port availability.
Is this switch suitable for rack mounting in a server cabinet?
Yes, the switch is designed for standard 19-inch rack mounting with a 1U form factor. It includes mounting brackets and fits seamlessly into server racks, network closets, or data center environments. The compact dimensions of 1.73" height, 17.52" width, and 13.58" depth ensure compatibility with most rack systems while providing front-panel access to all ports for easy cable management.
What management features does this Layer 2 switch offer?
As a Layer 2 managed switch, it provides web-based management for configuration, monitoring, and troubleshooting. Key features include VLAN support for network segmentation, quality of service (QoS) for traffic prioritization, port mirroring for diagnostics, and access control lists for security. These capabilities allow network administrators to optimize performance, enhance security, and maintain reliable business operations.
What is the warranty coverage for this refurbished switch?
