TP-Link TL-SG1048 48-Port Gigabit Rackmount Switch
Overview
The TL-SG1048 is a 48-port unmanaged gigabit switch purpose-built for equipment racks housing IP cameras, NVRs, access control systems, and PoE infrastructure. All 48 RJ-45 ports deliver 10/100/1000 Mbps throughput with automatic MDI/MDIX negotiation—no crossover cables needed, no configuration required. The 1U 19-inch form factor fits standard rack enclosures, consuming minimal space in server rooms, network closets, or on-site equipment cabinets. Switching capacity of 96 Gbps handles full-duplex traffic across all ports simultaneously, eliminating backplane congestion when aggregating multiple devices into a single rack.
Compatibility
The TL-SG1048 works with any Gigabit Ethernet device: IP cameras from all vendors, NVRs, DVRs, wireless access points, PoE midspan injectors, firewalls, and management workstations. It functions as a passive aggregation point and does not perform VLAN segmentation, QoS, traffic shaping, or MAC filtering. If your deployment requires port mirroring, remote management, or traffic prioritization for surveillance video, select a managed switch alternative. Standard Cat5e or better Ethernet cabling to cameras, PoE injectors, or intermediate distribution points is supported.
Installation Notes
External power adapter operation (100–240V, 50/60Hz) simplifies rack deployment—no dedicated PoE budgeting through the switch itself. Supports jumbo frames (12 KB) for large-file transfers between NVRs and storage. IEEE 802.3x flow control in full-duplex mode and backpressure in half-duplex mode prevent traffic congestion. Operating temperature range 0°C–40°C (32°F–104°F); confirm ambient conditions in your equipment cabinet meet this requirement. The switch features energy-efficient technology that adjusts power consumption based on link status, reducing operational carbon footprint. Complies with EU RoHS regulations.
