Removing A Hub From a
Stack
Reinserting a Hub into a Stack
If a removed hub is re-inserted back into the same stack, the Management
Module remembers all of the configuration for that hub. The reinserted hub
will quickly reconnect to the network and this hub will automatically be
reconfigured to the same port settings it had before it was removed.
Effect on Network Connectivity When a Hub
is Removed from a Stack
Network connectivity and network management flow through the Extender
Cables which connect each hub together in the stack. If you need to remove
a hub from a stack, the type of network connectivity lost during removal
depends on which hub was removed:
Not Top or Bottom Hub: If you disconnect a hub in the middle of the stack
by disconnecting the Extender Cables, network connectivity for the stack is
off for the disconnected hub, and on for the connected hubs. However, the
power remains on. Traffic between the two halves of the stack is resumed
when the Extender Cables are reattached.
Removed hub reinserted into the stack
Management Module
keeps configuration.
