❓ Frequently Asked Questions (FAQ)
🔌 Can the switch power IP PoE cameras and WiFi access points simultaneously?
Absolutely! The CRS328-24P-4S+RM has a PoE budget of 450W spread across 24 ports. It can simultaneously power IP cameras, WiFi access points, VoIP phones, and any equipment compatible with 802.3af/at. Each port delivers up to 30W with automatic power detection. Ideal for enterprise network installations, IP video surveillance, and WiFi infrastructures.
🚀 What is the difference between RouterOS and SwOS on this model?
This MikroTik switch offers Dual Boot: RouterOS (level 5) for advanced routing, firewall, VPN, QoS, and full Layer 3 features, or SwOS for ultra-fast Layer 2 switch configuration via an intuitive web interface. You can switch between the two systems depending on your needs. RouterOS is suitable for complex deployments requiring advanced routing and security, while SwOS is perfect for simplified and efficient switch management.
📡 Are the 10Gbps SFP+ ports compatible with my standard 1Gbps SFP modules?
Yes, the 4 SFP+ 10Gbps ports on the CRS328 are backward compatible with standard 1Gbps SFP modules. You can use optical modules (single-mode or multi-mode fiber), SFP+ copper modules, or DAC (Direct Attach Cable) to create 10Gbps links between switches or servers. This flexibility allows you to gradually upgrade your network backbone infrastructure according to your bandwidth needs.
🌐 Can I create VLANs to segment my network with this manageable switch?
Absolutely! The CRS328 supports up to 4096 simultaneous VLANs compliant with IEEE 802.1Q. You can segment your network by department, equipment type, or security level. Features include VLAN tagging, port isolation, ACL, and QoS for granular traffic management. Ideal for separating guest WiFi, IP video surveillance, VoIP, and enterprise data on the same physical infrastructure.
🔧 Is 19-inch rack mounting included with this rackmount switch?
Yes, this CRS328-24P-4S+RM comes with its rack mounting bracket included in the package. The standard 1U form factor (443mm wide) fits into any professional 19-inch rack bay. The switch has 2 fans for optimal cooling in datacenter or network cabinet environments. The universal 100-240V AC power supply allows installation worldwide without an additional transformer.
🌡️ Can this Gigabit switch operate in an uncooled environment?
The CRS328 is designed for demanding conditions with an operating temperature range from -20°C to +60°C. It is therefore suitable for installation in uncooled technical cabinets, server rooms, or industrial environments. The active cooling system with 2 fans ensures effective heat dissipation even under maximum PoE load. The MTBF (mean time between failures) is about 200,000 hours at 25°C, demonstrating MikroTik’s reliability for intensive professional use.
📊 What is the MAC address table capacity of this manageable switch?
The CRS328 switch features a MAC address table with 16,000 entries, more than enough for medium to large enterprise networks. With a non-blocking switching capacity of 128 Gbps and a forwarding rate of 95.2 Mpps (million packets per second), this Layer 2/3 switch delivers wire-speed performance on all ports simultaneously. The ARM Marvell Prestera 98DX3236 processor and its 512 MB of RAM efficiently handle dense network traffic with VLAN, link aggregation, and spanning tree protocols without performance degradation.
