PowerConnect 3448 and PowerConnect 3448P Stacking Overview PowerConnect 3424/P and PowerConnect 3448/P stacking provides multiple switch management through a single point as if all stack members are a single unit. All stack members are accessed through a single IP address through which the stack is managed. The stack is managed from a: • Web-based interface • SNMP Management Station • Command Line Interface (CLI) PowerConnect 3424/P and PowerConnect 3448/P devices support stacking up to six units per stack, or can operate as stand-alone units. During the Stacking setup, one switch is selected as the Stack Master and another stacking member can be selected as the Backup Master. All other devices are selected as stack members, and assigned a unique Unit ID. Switch software is downloaded separately for each stack members. However, all units in the stack must be running the same software version. Switch stacking and configuration is maintained by the Stack Master. The Stack Master detects and reconfigures the ports with minimal operational impact in the event of: • Unit Failure • Inter-unit Stacking Link Failure • Unit Insertion • Removal of a Stacking Unit 22 Introduction
