Four PoH outputs can provide a second power path for up to four compatible hosts through suitable Ethernet cabling.\u003c\/p\u003e\n\u003cp\u003eIts separate management interface supports status monitoring and port-priority settings.

The DPS-520 adds a supported redundant-power path to non-PoE DGS-1520-28 and DGS-1520-52 switches. Compatibility is model-specific; a familiar Ethernet connector does not make an arbitrary switch or PoE endpoint suitable.\u003c\/p\u003e\n\u003ch3\u003eAllocate the Shared Power Budget\u003c\/h3\u003e\n\u003cp\u003eThe four outputs share a total 180 W budget, with up to 90 W available from an individual output within that total. Four outputs do not mean four simultaneous 90 W loads. Size the complete installation and its priority settings for the intended hosts and failure conditions.\u003c\/p\u003e\n\u003ch3\u003eUse the Supported PoH Connection\u003c\/h3\u003e\n\u003cp\u003ePower over HDBaseT connections allow a compatible switch to receive its redundant power over standard CAT5e cabling at distances up to 100 m. Follow the host and supply instructions for the connection. Do not treat the output as an ordinary 802.3af\/at injector for cameras, phones or access points.\u003c\/p\u003e\n\u003ch3\u003eMonitor the Redundant Supply\u003c\/h3\u003e\n\u003cp\u003eA dedicated management interface separates administration from the four power outputs. Web status reporting and output priorities help the administrator understand the connected power arrangement. Protect access to this interface and test the intended failover behaviour before relying on the system.\u003c\/p\u003e\n\u003ch3\u003eFit the Equipment Layout\u003c\/h3\u003e\n\u003cp\u003eUse the supply as a standalone unit or mount suitable modules in the optional DPS-800 two-slot rack chassis. Allow clearance for ventilation, cable routing and service access. The chassis is a separate accessory; a redundant-power installation should be planned with the supported host and all required connection cables.\u003c\/p\u003e\n\u003ch3\u003eSeparate Redundancy From Battery Runtime\u003c\/h3\u003e\n\u003cp\u003eThe DPS-520 uses AC mains and contains no backup battery. It helps address a supported switch’s internal supply failure, but cannot provide runtime when all AC sources fail. Use a suitable UPS and a tested power arrangement if mains-outage continuity is required.\u003c\/p\u003e\n\u003ch2\u003eSummary\u003c\/h2\u003e\n\u003cp\u003eThe DPS-520 is a dedicated redundant-power option for supported non-PoE DGS-1520 switches. Its four outputs, shared budget and management functions support a deliberate availability design when the host models, cabling, power priorities and separate UPS requirements are checked together.\u003c\/p\u003e\n\u003csection class=\"ace-article-faq\" aria-label=\"Frequently asked questions\"\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdetails class=\"ace-form-disclosure\" open\u003e\u003csummary\u003e\u003ch3 class=\"ace-form-title\"\u003e\n\u003cspan class=\"ace-form-title-text\"\u003eWhich Switches Does It Support?\u003c\/span\u003e\u003cspan class=\"ace-form-toggle\" aria-hidden=\"true\"\u003e\u003cspan class=\"ace-form-expand\"\u003eExpand\u003c\/span\u003e\u003cspan class=\"ace-form-collapse\"\u003eCollapse\u003c\/span\u003e\u003cspan class=\"ace-form-chevron\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\u003c\/summary\u003e\u003cdiv class=\"ace-form-body\"\u003e\u003cp\u003eThe verified application is the non-PoE DGS-1520-28 and DGS-1520-52.
