Hot Remove
The Fast EtherHub 3500 System supports “hot remove” capability that allows you to connect/disconnect hubs or media connectors from the system with minimal disruption to the network. You can remove any network cabling without affecting traffic passing across the internal repeater bus. However, if the FlexBus 3500 stack cable is disconnected at any point in the stack, or is not properly terminated, all Ethernet and management traffic passing across the stack’s backplane will be disrupted.
ΙWhen changing modules in the expansion slot or changing power supply modules, first disconnect power to the concerned hub.
