The order in which stack members are arranged is established not by thephysical order of the stack members but by the Unit ID assignment. The stackconfiguration is stored in stack master after the stack order is changed, and the stack isreset.If the PowerConnect 3324/3348 unit is removed or replaced in a stack, the stack recoversfrom the disconnection as follows:• If the stack is disconnected for more than two minutes, the entire stack no longerforwards network traffic. Every stack member reboots and waits until the stack isreconnected. If the unit is not replaced, the master unit constantly polls the stack.• If the stack is reconnected in under two minutes, all units remain stacked and regaintheir connection to other units within five seconds. A new stack member is connectedto the master unit but initialized according to the master unit’s configuration. If aconfiguration is not stored, the device is configured with the default configuration.Replacing Stack MembersIf a stack member is replaced with a new device, the requested device ID is selected. Inaddition, the previous device configuration is applied to the inserted stack member. If thenew inserted device has either more or fewer ports than the previous device, the relevantport configuration is applied to the new stack member. For example:• If a PowerConnect 3324 replaces a PowerConnect 3324, the new 24 10/100 BaseTports receive the previous 24 10/100 BaseT port configuration. Ports G1 and G2 receivethe previous device’s G1 and G2 port configuration.• If a PowerConnect 3324 replaces PowerConnect 3348, then ports 1-24 10/100 BaseTreceive the previous device’s configuration for ports 1-24. Ports G1 and G2 receive theprevious device’s G1 and G2 port configuration.
