If an Aggregator is already configured to operate in stacking mode, simply attach SFP+ or direct attach cables to connect 10G ports on the base module of each stacked Aggregator. The new unit synchronizes its running and startup configurations with the stack. Dell Networking OS Behavior: When you add a new Aggregator to a stack: • If the new unit has been configured with a stack number that is already assigned to a stack member, the stack avoids a numbering conflict by assigning the new switch the first available stack number. • If the stack has been provisioned for the stack number that is assigned to the new unit, the preconfigured provisioning must match the switch type. If there is a conflict between the provisioned switch type and the new unit, a mismatch error message is displayed. Resetting a Unit on a Stack Use the following reset command to reload any of the member units or the standby in a stack. If you try to reset the stack master, the following error message is displayed: % Error: Reset of master unit is not allowed. To reset a unit on a stack, use the following command: • Reset any designated stack member, except the management unit. EXEC Privilege mode reset stack-unitunit-number {hard} • Hard reset any stack unit including master unit. EXEC Privilege mode power-cycle stack-unit [unit-number] Removing an Aggregator from a Stack and Restoring Quad Mode To remove an Aggregator from a stack, follow the below steps: 1. Disconnect the stacking cables from the unit. The unit can be powered on or off and can be online or offline. 2. Log on to the CLI and enter Global Configuration mode. Login: username Password: ***** FTOS> enable FTOS# configure 3. Configure the Aggregator to operate in standalone mode. CONFIGURATION stack-unit 0 iom-mode standalone 4. Log on to the CLI and reboot each switch, one after another, in as short a time as possible. EXEC PRIVILEGE reload When the reload completes, the base-module ports comes up in 4x10GbE (quad) mode. The switch functions in standalone mode but retains the running and startup configuration that was last synchronized by the master switch while it operated as a stack unit. 192 Stacking
