FAQ
How many devices can I connect to this switch?
The Ubiquiti US-48-500W provides 48 Gigabit Ethernet ports, allowing direct connections for up to 48 devices such as computers, printers, IP phones, or access points. Additionally, the four SFP/SFP+ expansion slots can be used for uplinks to other switches or network segments, effectively supporting larger networks through cascaded connections.
Does this switch support Power over Ethernet (PoE)?
No, this switch does not provide PoE on its RJ45 ports. It is designed as a data-only switch, focusing on Gigabit connectivity and uplink flexibility. If PoE is required for devices like wireless access points or IP cameras, you would need to use separate PoE injectors or consider a PoE-capable switch model from the UniFi lineup.
What types of uplink connections are possible with the expansion slots?
The switch includes four expansion slots: two SFP slots for Gigabit connections and two SFP+ slots for 10 Gigabit connections. These slots support SFP or SFP+ modules for fiber (e.g., 1000Base-X, 10GBase-X) or copper uplinks, allowing you to connect to core switches, servers, or other network equipment at high speeds based on your infrastructure needs.
Is this switch manageable, and how is it configured?
Yes, the US-48-500W is a Layer 2 managed switch.
