Powering On Switch Stacks
Switches in stacked Switch groups should be powered on simultaneously after all the FireWire connections are
in place. The auto-detect mechanism of the stacking function requires that all participating Switches share MAC
address information at the same time to establish the stack order. Once the group hierarchy has been established,
it can only be changed using a software-driven override or a factory reset of each Switch in the group followed
by simultaneous power on.
Cable Connections for a Stacked Switch Group
Interconnection of the Switch stack is accomplished using IEEE 1394 “FireWire” cabling. The ports used to
connect the Switch stack are referred to here as the “stacking” ports. For uplink to the Ethernet backbone, it is
recommended that the Master Switch be used, although other Switches in the stack can be used for uplink.
Follow these steps to connect the stacked devices:
1. Connect the FireWire port on the Master Switch labeled “Out” to the FireWire port labeled “In” on
the Number 2 Switch.
2. Connect the FireWire port of the Number 2 Switch labeled “Out” to the FireWire port of the Number
3 Switch. Continue to connect the stacking ports of all the Switches in the stack in a likewise fashion.
3. Connect the FireWire port labeled “Out” on the last Switch in the stack i.e. the highest numbered
Switch, to the FireWire port labeled “In” on the Master Switch.
4. Finally, you can connect the Uplink port (10/100BASE-TX) to the Ethernet backbone with Category
5 cabling with RJ-45 connectors.
