Cisco MA-CBL-SPWR-150CM is a 1.5 m stacking cable manufactured by Cisco for the Meraki MS390 Series switches. It is a dedicated switch stacking cable with proprietary stacking interfaces designed to interconnect MS390 units and support high-speed stack data transmission between members of the same stack.
The cable is compatible with all Cisco Meraki MS390 models and is used to create a physical stack for unified switch management and control. At 150 cm in length, it supports flexible rack placement within standard equipment cabinets. It functions as a passive stacking interconnect and does not provide external power delivery.
