MikroTik CSS318-16G-2S+IN 16-Port Gigabit Managed Switch with 2x 10G SFP+ Uplinks (SwOS)

MikroTik CSS318-16G-2S+IN — 16-Port Gigabit Managed Switch with 2x 10G SFP+ Uplinks for ISP & Enterprise Networks

The MikroTik CSS318-16G-2S+IN is a compact, high-performance 16-Port Gigabit Managed Switch with 2x 10G SFP+ uplink ports, purpose-built for ISPs, WISPs, and enterprise networks across Uganda and East Africa. Running MikroTik SwOS, this switch delivers Layer 2 managed switching — including VLAN, RSTP, bandwidth limiting, and port mirroring — through a clean, browser-based interface that requires no CLI expertise.

Engineered in MikroTik's signature white 1U rackmount chassis, the CSS318-16G-2S+IN brings 10G backbone uplinks to a 16-port access switch at a price point that makes sense for Ugandan ISP distribution layers, hotel networks, and SMB server rooms. When you need to aggregate 16 Gigabit devices and hand off to a 10G fibre core, this switch does it cleanly and reliably.

Key Features

• 16x Gigabit Ethernet ports — wire-speed 1G on every access port, no oversubscription

Ideal Use Cases for Uganda & East Africa ISPs

The CSS318-16G-2S+IN hits the sweet spot between affordability and 10G uplink capability, making it the ideal access-layer switch for a wide range of East African deployments:

• ISP access layer aggregation — connect 16 CPE devices or subscriber ONUs with VLAN isolation per customer, then hand off at 10G to your core
• WISP tower distribution — aggregate multiple sector radios and backhaul links at your tower site with per-port bandwidth control
• Hotel & campus wired networks — provide dedicated Gigabit to each room or office with VLAN segmentation for guest, staff, and management traffic
• SMB server & NAS backbones — connect servers, NAS, hypervisors, and workstations at 1G with a 10G uplink to your core
• NOC infrastructure switching — manage billing servers, NMS platforms, and monitoring tools on isolated VLANs

ISP Billing & Subscriber Management Integration

The CSS318-16G-2S+IN integrates directly into MikroTik-based ISP network architectures. Its per-port VLAN and bandwidth limiting features work seamlessly alongside a RADIUS-based edge router to enforce subscriber policies. Connect your network to our purpose-built ISP billing and subscriber management platform for automated PPPoE session management, bandwidth throttling, invoicing, and real-time reporting:

Frequently Asked Questions

Q: What is the difference between SwOS and RouterOS on this switch?

SwOS is a lightweight browser-based Layer 2 OS for VLAN, RSTP, port mirroring, and bandwidth limiting. It does not support full routing. For PPPoE, RADIUS, and firewall, pair it with the MikroTik hEX S router.

Q: Does it support 10G SFP+ fibre uplinks?

Yes — both SFP+ ports support 10G SMF, MMF, and DAC cables. MikroTik-branded SFP+ modules recommended for full compatibility.

Q: Is it suitable for ISP subscriber distribution?

Yes. Per-port VLAN isolation and bandwidth limiting make it ideal for aggregating subscriber CPE. Pair with the MikroTik ISP Starter Kit and our ISP billing platform for full subscriber automation.

Q: Does it support VLANs?

Yes — IEEE 802.1Q with port-based and tagged VLAN configuration via the SwOS browser interface. Isolate subscriber, guest, staff, and management traffic on separate logical networks.

Q: Is it available in Uganda?

Yes. NetEdge Supplies stocks it at UGX 460,000. Delivery to Kampala, Entebbe, Jinja, Mbarara, and Gulu. Bulk ISP pricing on request.

Q: Can it be powered via PoE?

Yes — Port 1 accepts 24V passive PoE input from a MikroTik PoE router or injector, ideal for tower and field cabinet deployments without a separate DC power run.
