## Long description

The MikroTik CRS354-48P-4S+2Q+RM is a 1U rack-mountable managed L3 switch offering 48 Gigabit RJ45 ports with PoE support, 4 x 10G SFP+ ports and 2 x 40G QSFP+ ports for high-speed uplinks. Designed for professional network environments, it provides configurable PoE on all 48 Ethernet ports (Passive PoE, low-voltage PoE, 802.3af and 802.3at) and comes with a 750 W power supply and a cable management bracket.
Advantages
The switch combines high port density with multi-standard PoE output, allowing flexible power delivery to a wide range of devices. With 4 SFP+ and 2 QSFP+ ports it supports both 10 Gbps and 40 Gbps fiber uplinks or stacking. The device is built for rack installation with an included power supply and cable management bracket, and it offers non-blocking throughput and hardware performance suitable for demanding deployments.
Suitable for
Enterprise and data center access/aggregation layer
Powering PoE devices such as IP cameras, VoIP phones and wireless access points
High-bandwidth uplinks and fiber interconnects between switches
Racked network installations requiring centralized PoE power

Form factor: 1U rack-mountable with cable management bracket
How to use
Install the CRS354-48P-4S+2Q+RM into a standard 19-inch rack using the provided mounting hardware. Connect uplinks to the SFP+ or QSFP+ ports for 10 Gbps or 40 Gbps links and attach end devices to the RJ45 ports. Configure PoE mode per port to match connected devices (Passive PoE, low-voltage, 802.3af or 802.3at) and set required network parameters through the switch management interface for VLANs, routing and access control.
Usage recommendations
Verify connected device PoE requirements before enabling power on each port, and plan total power consumption to stay within the 750 W supply budget. Use SFP+/QSFP+ modules and quality fiber or DAC cables that match the desired link speed and distance. For large deployments, segregate uplink and access traffic with VLANs and monitor power and port utilization from the management interface.
