The TP-Link 18-Port Gigabit Rackmount Switch offers comprehensive network connectivity with integrated Power over Ethernet Plus (PoE+) functionality. This switch model features 16 Gigabit Ethernet ports that comply with the 802.3at/af PoE+ standards, providing a total power budget of up to 250 W for directly powering compatible devices such as IP cameras, Wi-Fi access points, and VoIP phones over network cables. Two additional Gigabit Ethernet ports offer standard connectivity without PoE functionality, while two combined Gigabit SFP slots enable fiber connectivity options for network expansion or connection to fiber backbones. Designed for rack installation in professional environments, this switch measures 44.4 cm in width, 22.0 cm in depth, and 4.4 cm in height (1U height), making it suitable for standardized 19-inch rack cabinets. The metal housing ensures durability and efficient heat dissipation during continuous operation. With a switching capacity of 36 Gbps and a forwarding rate of 26.8 million packets per second, this switch delivers reliable performance for small to medium business networks, surveillance systems, and office environments. The fanless design allows for quiet operation in noise-sensitive locations. Management features include support for VLAN, QoS, IGMP Snooping, and port mirroring functions for network optimization and monitoring. The switch operates within a temperature range of 0°C to 40°C and requires 100-240 V AC input power. All ports support auto-negotiation and auto-MDI/MDIX for simplified installation without manual configuration. The compact 1U form factor maximizes rack space efficiency while providing substantial connectivity options for expanding the network infrastructure.
