D-Link DIS-210G-12 Industrial Smart Managed Switch, 12-Port

Applications

Highlights

• 8x 10/100/1000BASE-T ports plus 4x 1G SFP slots for long-distance fiber uplinks
• Redundant 12-55V DC dual power input via terminal block for uninterrupted operation
• -40°C to 75°C operating range and IP40 housing for cabinets and DIN-rail mounting
• Layer 2 ring redundancy (ERPS, sub-50ms recovery) and link aggregation
• Comprehensive security and management features for professional network operation

Technology Overview

With a 24 Gbps switching capacity and a 17.85 Mpps forwarding rate, the DIS-210G-12 reliably handles data-intensive industrial networks. STP/RSTP/MSTP and ERPS v1/v2 protect ring topologies, while 802.1AX/802.3ad link aggregation bundles bandwidth across up to 8 groups of 8 ports each. 802.1Q VLAN support, granular QoS with 8 queues per port, and IGMP/MLD snooping round out the feature set. Cable diagnostics, 802.3ah Ethernet Link OAM, and 802.1ag Connectivity Fault Management simplify troubleshooting across extended networks, while RMON v1/v2 and system logging support continuous operational monitoring.

Security & Management

Port security, DHCP snooping, dynamic ARP inspection, and IP source guard protect against unauthorized access, while 802.1X and RADIUS/TACACS+ handle user authentication. Management runs through an encrypted web GUI, SSH/CLI, or SNMP v1/v2c/v3 — including dual-image support for uninterrupted firmware upgrades.

Notes

The DIS-210G-12 has no PoE capability; for powering connected devices, see the DIS-210G-12P (PoE+) and DIS-210G-12UP (PoE++) variants. Compatible DIS-S3xx series SFP transceivers extend fiber runs to various distances. With an MTBF above 200,000 hours and compact dimensions of 164 x 107 x 44 mm at 0.72 kg, the switch fits space-efficiently into existing control cabinets.
