Problems updating catalyst
Up to four switches can be configured in a Stack Power stack with the special connector at the back of the switch using the Stack Power cable**, which is different than the Stack Wise cables.
Stack Power can be deployed in either power sharing mode or redundancy mode.
Based on the license's type, Cisco IOS Software activates the appropriate feature set.
Stack Wise technology was designed to respond to additions, deletions, and redeployment while maintaining constant performance.The Cisco® Catalyst® 3750-X Series Switches are an enterprise-class lines of stackable and standalone switches, respectively.These switches provide high availability, scalability, security, energy efficiency, and ease of operation with innovative features such as IEEE 802.3at Power over Ethernet Plus (Po E ) configurations, optional network modules, redundant power supplies, and Media Access Control Security (MACsec) features.A working stack can accept new members or delete old ones without service interruption.
Stack Wise creates a highly resilient single unified system of up to nine switches, providing simplified management using a single IP address, single telnet session, single command-line interface (CLI), auto-version checking, autoconfiguration, and more.
Software activation authorizes and enables the Cisco IOS Software feature sets.
