Advantages

Here are the advantages of the MikroTik CRS328-24P-4S+RM:

✅ High PoE Capacity

• Supplies power to up to 24 PoE devices (like Wi-Fi APs, IP cameras, VoIP phones) directly from the switch.

• Large total PoE power budget, reducing need for separate injectors.

✅ Flexible Uplink Options

• 4 × 10 Gbps SFP+ ports provide high-speed connections to servers, core switches, or fiber networks.

✅ Advanced Network Management

• Run RouterOS (robust routing and Layer 3 features) or SwitchOS (simplified switch-centric interface).

• Supports VLANs, link aggregation (LACP), STP/RSTP/MSTP, ACLs, IGMP snooping, monitoring tools, and more.

✅ Scalable and Professional

• Rackmount (1U) design ideal for medium to large networks in enterprises, campuses, and ISP access layers.

• Metal chassis and fans built for continuous operation.

✅ Cost-Effective for the Features

• Combines managed switching + PoE + 10G uplinks in one unit — often more cost-efficient than separate devices.

✅ Reliable and Extensible

• Serial console access for recovery and advanced management.

• Fans with temperature control enhance lifespan and stability.
