Cisco WS-CAC-1300W enterprise networking (router/Catalyst switch/UCS families) Datacentre Switch

The Cisco WS-CAC-1300W (Cisco part number 34-0918-02) is a 1300W AC power supply for the Catalyst 6000 and 6500 series switch chassis, including the 6009, 6509 and 6513, converting a 100-240VAC mains input to the -48VDC the chassis backplane distributes to its Supervisor and line-card modules. As with other Catalyst 6000/6500 supplies, a second unit can be fitted alongside it for N+1 redundancy so the chassis stays powered through a single supply failure, and the exact power budget needed depends on how many line cards and PoE-capable modules the chassis is running. Catalyst 6000/6500 chassis of this generation remain in service across many established enterprise networks, and a genuine spare such as this restores full power budget after a supply failure. Tech-Star (UK-based, shipped worldwide) stocks Cisco power supplies for engineers maintaining these platforms.
