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 same 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. This procedure assumes that the new switch being added has a clean configuration from manufacturing and is running the same firmware image version as other switches in the stack. 1. Ensure that power is off on the new switch being installed. 2. Use one of the following methods to complete the stack cable connections: 3.
