Stackable switch

A stackable switch is a <a href="/facts/Network_switch/CnvmhNYT">network switch</a> that is fully functional operating standalone but which can also be set up to operate together with one or more other network switches, with this group of switches showing the characteristics of a single switch but having the <a href="/facts/Port_(computer_networking)/ygoHVKNC">port</a> capacity of the sum of the combined switches.
The term stack refers to the group of switches that have been set up in this way.
The common characteristic of a stack acting as a single switch is that there is a single <a href="/facts/IP_address/z9V22Sw9">IP address</a> for <a href="/facts/Remote_administration/sPIwCm1S">remote administration</a> of the stack as a whole, not an IP address for the administration of each unit in the stack. 
Stackable switches are customarily Ethernet, <a href="/facts/19-inch_rack/yFvLAnBg">rack</a>-mounted, managed switches of 1–2 rack unit (RU) in size, with a fixed set of data ports on the front. Some models have slots for optional slide-in modules to add ports or features to the base stackable unit. The most common configurations are 24-port and 48-port models.
