48-Port Gigabit Rackmount Switch

The TP-Link TL-SG1048 is an unmanaged 48-port Gigabit Ethernet switch built for rackmount installation. It delivers 48 RJ45 ports operating at 10/100/1000Mbps with a 96Gbps switching capacity and an 8K MAC address table. The fanless metal chassis runs silently in 0°C to 40°C environments. It suits workgroups and departments that need simple, high-density wired connectivity without configuration overhead.

Plug-and-Play Accessories

The box contains the switch, a power cord, and a user guide. No software or licences are bundled. Auto MDI/MDIX on every port removes the need for crossover cables, and auto-negotiation handles speed and duplex automatically. 802.3X flow control and back-pressure support help prevent packet loss during congestion. The 100-240VAC internal power supply accepts global mains voltages without an external adapter.

Pre-Installation Checks

Verify that your rack provides a 1U space measuring at least 17.3 inches deep and 14.2 inches wide to accommodate the unit. Ensure the site temperature stays within 0°C to 40°C and humidity remains below 90 per cent non-condensing. Confirm you have a grounded AC outlet supplying 100-240V at 50 or 60Hz for the 29.8-watt maximum draw. This switch is unmanaged, so buyers who need VLANs, QoS configuration, or SNMP monitoring should choose a managed model instead.

Questions about this item

Will the fanless cooling need any maintenance or replacement over time?

The switch uses a fanless design with no moving parts, so no fan maintenance or replacement is required.

What is the maximum switching capacity the TL-SG1048 can sustain continuously?

The non-blocking architecture provides a 96Gbps switching capacity at full wire speed across all 48 ports.

How much power does the unit draw and how much heat does it produce when running 24/7?

Maximum power consumption is 29.8 watts at 220V/50Hz, and the fanless metal chassis dissipates heat silently within the 0°C to 40°C operating range.
