CAB-SPWR-30CM, Cisco 3750X/3850 Stack Power Cable, 30CM, Refurbished
Warranty: Lifetime
Condition: Refurbished
Cisco Catalyst CAB-SPWR-30CM StackPower Cable
Product Overview The Cisco CAB-SPWR-30CM is a 30 cm (0.3 m / 1 ft) StackPower cable designed for Cisco Catalyst 3850 and 9300 Series switches. It enables power sharing and redundancy across stacked switches via the Cisco StackPower technology, allowing up to four power supplies to form a single power pool of up to 4,380 watts. This compact cable is ideal for front-to-back or adjacent stacking configurations in high-density racks.
