It is the forward-airflow unit in Cisco's wording, which NetworkTigers lists as back-to-front: cooling air enters at the power supply side and exits at the port side. The reversed version for port-side intake rows is the N2200-PAC-400W-B.\u003c\/p\u003e\r\n\u003cp\u003eThe supply takes standard 100 to 240V AC input at 50 to 60 Hz and runs at 89 to 91 percent efficiency at 220V. Each compatible chassis carries two power supply bays, so fitting a second supply gives 1+1 redundancy, and the units are hot-swappable, so a failed supply can be replaced while the switch keeps running on its partner.\u003c\/p\u003e\r\n\u003cp\u003eCisco's ordering tables list this part for the Nexus 3048, 3064, 3132Q, 3172PQ, and 3500 Series switches, and the Nexus 2248TP and 2232PP fabric extenders. Every power supply and fan module in one chassis must share the same airflow direction, so pair this unit with forward-airflow fan trays.\u003c\/p\u003e\r\n\u003cp\u003eIt powers switches such as the \u003ca href=\"https:\/\/www.networktigers.com\/products\/n3k-c3048tp-1ge-cisco-48x-1-gigabit-rj45-4x-10-gigabit-sfp-front-to-back-airflow-switch\"\u003eNexus 3048TP-1GE\u003c\/a\u003e.

Running two supplies from separate feeds keeps the switch up through a single circuit failure, and a cold spare on the shelf turns a supply failure into a one-minute swap.\u003c\/p\u003e\r\n\u003cp\u003eThis seller refurbished power supply is tested, working, and covered by the NetworkTigers one-year warranty.\u003c\/p\u003e","brand":"Cisco","offers":[{"title":"Default Title","offer_id":16698920902,"sku":"NSH-2564","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/9318\/products\/cisco-N2200-PAC-400W_4f69849f-7a16-4dc6-ad63-c289f6330ca9.jpg?v=1676066072","url":"https:\/\/www.networktigers.com\/products\/n2200-pac-400w-cisco-400w-ac-back-to-front-airflow-port-side-exhaust-power-supply","provider":"NetworkTigers","version":"1.0","type":"link"}
