Description

The CAB-SPWR-35CM is a 35 cm StackPower interconnect cable from the Cisco Catalyst StackPower accessories range. It links the StackPower ports between stackable Cisco Catalyst switches so the stack members can share power as a single pool. It suits campus and branch access layers where switches sit next to each other in the same rack.

The cable is passive, with no power supply of its own, and simply carries shared power between stack members. Pooling supplies lets you add redundancy or extra capacity by fitting a single power supply to any switch in the stack. On the Catalyst C9350 Series, StackPower+ is a 55V power-sharing architecture that supports up to four switches in a ring and full 90W PoE on all ports using shared power. At 35 cm it is the short option for adjacent switches, while the 100 cm CAB-SPWR-100CM covers wider spacing. No licence is required for the cable itself.

Cisco lists CAB-SPWR-35CM as the StackPower cable for the Catalyst C9350 Series Smart Switches. The C9350 is not compatible with StackPower cables from the Catalyst 9300 Series or other previous-generation switches, so confirm the cable against your specific switch model before ordering.

Enquire with XS Network Tech for new or used pricing and availability.
