User Manual
FAQ
How many network ports does this QNAP switch have?
The QNAP QSW-2104-2S-A-US provides four 2.5 Gigabit Ethernet RJ45 ports for connecting network devices. Additionally, it includes two SFP+ expansion slots that support 10 Gigabit Ethernet modules for high-speed uplink connections to core network infrastructure.
Is this switch managed or unmanaged?
This is an unmanaged Layer 2 switch, meaning it operates automatically without requiring configuration, management interfaces, or specialized software. All ports auto-negotiate speed and duplex settings, while built-in Layer 2 features like IGMP snooping and spanning tree protocol function without user intervention.
What type of cabling does this switch support?
The switch supports standard twisted pair Ethernet cabling (CAT5e, CAT6, or CAT6a) for all four RJ45 ports. This allows for cost-effective deployment using widely available cables with maximum supported distances of 100 meters per connection. The SFP+ slots accept compatible SFP+ modules for either fiber or copper connections.
What are the SFP+ slots used for on this switch?
The two SFP+ expansion slots provide 10 Gigabit Ethernet uplink capability, allowing connection to core switches, routers, or servers at higher speeds than the 2.5GbE ports. These slots accept standard SFP+ transceiver modules for either fiber optic or copper connections, offering flexibility for different network infrastructure requirements.
What Layer 2 features does this switch include?
As a Layer 2 switch, it includes essential features such as IGMP snooping for efficient multicast traffic handling, port mirroring for network monitoring and troubleshooting, and spanning tree protocol for preventing network loops. These features operate automatically in the background without requiring configuration.
Is this switch suitable for connecting to a 10GbE network?
Yes, through its two SFP+ expansion slots, this switch can connect to 10 Gigabit Ethernet networks. By installing compatible SFP+ modules, you can establish 10GbE uplinks to core network equipment while the four 2.5GbE ports handle device connections. This makes it effective for integrating 2.5GbE devices into existing 10GbE infrastructure.
