Configuring Switches in a Stack Once installed in a stack, the switches behave and perform as a single switch. As such, you can start with a single switch and add more switches as your network expands. You can also mix different products in the family in a single stack to provide a desired combination of port types and functions to match the requirements of individual applications. In all cases, a stack of switches performs as one large product, and is managed as a single network entity.
Configuring Switches in a Stack Recommended Procedures for New and Existing Stacks Important The following procedures assume that all switches have a clean configuration from manufacturing. When adding a new switch to an already running stack, it is also assumed that the new switch is using the same firmware image version as other switches in the stack. Installing a New Stackable System of Up to Eight Switches Use the following procedure to install a new stack of up to eight switches out of the box.
Connecting AC and RPS-SYS Power Adding a New Switch to an Existing Stack Use the following procedure to install a new switch to an existing stack configuration.
