{"answer":"Long outdoor Ethernet cables can carry surge energy from lightning or nearby electrical events, even without a direct strike. Use appropriate outdoor-rated cable, correct separation from power conductors, shield and earth only according to the designed system, and install surge protection at suitable entry points.\n\nEthernet has a practical 100-metre channel limit under standard conditions, and voltage drop can become significant for PoE at high power. Water entry, poor terminations and ground-potential differences can also cause intermittent faults or equipment damage. Outdoor grounding and lightning protection should be designed for the site by a competent installer; simply adding a metal enclosure does not solve the risk.","approval_status":"draft_for_dave_review_pending_public_brain_audit","approved":false,"category":"Power over Ethernet Deployments","category_slug":"power-over-ethernet-deployments","created_at":"2026-06-13T09:10:00+00:00","daily_publish_cap":2,"date_published":"2026-06-13","display_date":"2026-06-13","drip_status":"review_seed","freshness_note":"Confirm current model specifications, carrier compatibility, stock, pricing, firmware, warranty and commercial terms directly with Comset where they affect a decision.","id":"comset-qa-042","image_ids":["comset-product-poe-2401","comset-category-hero-014-power-over-ethernet-deployments"],"language":"en-AU","last_updated":"2026-06-13T09:10:00+00:00","matched_image_ids":["comset-product-poe-2401","comset-category-hero-014-power-over-ethernet-deployments"],"public_brain_verified":false,"publish_status":"review_preview","published_at":"2026-06-13T09:10:00+00:00","question":"What grounding, surge and cable-length issues should be considered in an outdoor PoE deployment?","question_intent":"public_guidance","question_type":"deployment_or_troubleshooting","real_image_mapping_status":"mapped_to_approved_comset_catalogue_v1_6","site_key":"comset","slug":"what-grounding-surge-and-cable-length-issues-should-be-considered-in-an-outdoor-poe-deployment","source":"Comset public website scrape and stable industrial-networking explanation","source_record_ids":["comset-source-0348","comset-source-0351","comset-source-0352","comset-source-0395"],"source_type":"client_source_plus_stable_explanatory_context","source_urls":["https://comset.com.au/product/power-over-ethernet-adapter-poe-2401","https://comset.com.au/product/5g-4g-3g-wifi-router-with-dual-sim-cm550w-poe","https://comset.com.au/product/5g-4g-3g-outdoor-router-cm580w"],"tenant_slug":"comset","updated_at":"2026-06-13T09:10:00+00:00"}
