This is a Cisco compatible 1m FlexStack stacking cable that can connect a combination of Catalyst 2960-X and 2960-XR stackable switches to form a single switching unit. Our Cisco data cables are specifically intended to work with Gigabit Ethernet, while also making it easy to allow switch additions, deletions and redeployment without interruption. Furthermore, you can use these data cables to stack up to eight switches to become a single unit with one master switch.
