D-Link DWM-311-GP 5G Dual-SIM M2M PoE+ Modem

5G Backhaul and PoE+ Power in a Compact Gateway Give a compatible remote endpoint a fast cellular uplink and a powered 2.5GbE connection, with dual SIM slots for carrier failover. The DWM-311-GP combines a cellular WAN, 1 × 10/100/1000/2500 Mbps 2.5GbE PoE+ LAN and remote-management tools in a compact metal enclosure. Choose it for protected installations where the network must reach equipment beyond an ordinary fixed broadband connection. Highlights Cellular Connectivity 5G cellular WAN with 4G LTE support 2 × Nano-SIM (4FF) with automatic failover External cellular antenna connectors Wired Installation 1 × 10/100/1000/2500 Mbps 2.5GbE PoE+ LAN 30W shared PoE+ output budget with up to 30W per powered port NAT/router and bridge modes; static routing Practical Management OpenVPN and WireGuard clients Web management and SMS event tools D-ECS remote management support with separate licensing Key Features A Mobile Uplink for the Right Application Give a compatible remote endpoint a fast cellular uplink and a powered 2.5GbE connection, with dual SIM slots for carrier failover. A suitable mobile data plan and signal at the actual installation are essential. This is an Ethernet cellular modem/router, with no built-in Wi-Fi access point. Add a suitable access point separately when wireless clients are required. Wired Connections That Match the Equipment The modem provides 1 × 10/100/1000/2500 Mbps 2.5GbE PoE+ LAN. Its 30W shared PoE budget supplies up to 30W per powered port at the PSE, for compatible IEEE 802.3af/at devices. PoE is an output: feed the modem from the supplied DC adapter or a correctly rated DC source, rather than expecting a PoE switch to power it. SIM Planning for a Dependable Connection Dual SIM slots allow automatic switching to a backup mobile connection when the primary connection fails. This is failover rather than two simultaneous cellular modems or bonded bandwidth. Use suitable active plans, ideally with different carriers. Secure Remote Access with Clear Boundaries OpenVPN and WireGuard clients help establish encrypted connections to a configured remote VPN endpoint. Web management, SMS event tools and connection monitoring support remote maintenance. Configure access controls and the receiving VPN service carefully; mobile carrier CGNAT can prevent unsolicited inbound access even when port forwarding is configured. Built for Protected Industrial Installations A corrosion-resistant metal enclosure and an operating range of −30 to 70°C suit protected industrial installations. Wall or DIN-rail installation; DIN-rail kit included in the standard package. The power input is 48–57V DC via 2-pin terminal block. Keep the unit dry and ventilated; this is not an IP-rated outdoor enclosure. Manage One Device or a Wider Deployment Use the local Web UI for setup, firmware maintenance and status checks. D-ECS offers central remote management for supported deployments, but requires a separate device licence or an applicable included entitlement. Keep the carrier plan, licensing and installation requirements in the deployment budget. Summary DWM-311-GP is a focused choice for powered remote equipment that needs both cellular data and PoE+ delivery. Match the SIM, carrier coverage, regional radio specification and power arrangement to the site, then configure remote access and management to suit the application. Frequently Asked Questions Does this modem provide Wi-Fi?ExpandCollapse No. It provides cellular WAN and wired Ethernet connectivity. Connect a separate access point or suitable router if phones, laptops or other Wi-Fi clients need wireless access. Which SIM card and mobile network should I use?ExpandCollapse 2 × Nano-SIM (4FF) with automatic failover. The listed radio bands follow the offered regional specification. Confirm the supplied regional hardware, carrier bands, APN and data-plan permission before deployment; a SIM and mobile subscription are not included. Does it support dual-SIM failover?ExpandCollapse Dual SIM slots allow automatic switching to a backup mobile connection when the primary connection fails. This is failover rather than two simultaneous cellular modems or bonded bandwidth. Use suitable active plans, ideally with different carriers. Can this modem power a PoE camera or access point?ExpandCollapse Yes, compatible IEEE 802.3af/at devices can use its 1 PoE+ output port, with up to 30W per port and a 30W shared budget at the PSE. The modem itself needs 48–57V DC via 2-pin terminal block. Check the endpoint power requirement and cable losses. Will remote access work through every mobile data plan?ExpandCollapse Not automatically. Carrier CGNAT, APN restrictions and firewall policies can affect inbound access. A correctly configured outbound VPN or an appropriate public/static-IP carrier service may be required. Advertised cellular rates are theoretical and depend on coverage, signal and network load. What is included and is cloud management free?ExpandCollapse The standard package includes 4 cellular antennas, an Ethernet cable and a power adapter. A 2-pin terminal block and DIN-rail kit are also included. D-ECS licensing is separate unless a specific included entitlement applies. SIM cards, mobile data plans and any additional access point are separate. Magbasa pa
