Mode Button
The Mode Button toggles between port activity and port duplex settings.
Stack ID Button
The PowerConnect 3324/3348 front panel contains a Stack ID button that permits network
administrators to manually select the Stack Master and stack members.
NOTE: The Stack Master and stack members must be selected within 15 seconds after booting
the device. If the Stack Master is not selected within 15 seconds, the device must be reset to
select the Unit IDs.
Once the Stack Master is selected, the remaining devices are defined as stack members.
Master units receive the Unit ID of 1. Stack members receive a separate Unit ID (2-6). For
example, if there are 4 units in a stack, the Master unit is 1, the second stack member is 2,
the third stack member is 3, and the fourth stack member is 4.
Stacking Modules and Connectors
PowerConnect 3324/3348 Stacking modules are connected to port G2. The Stack module is
a mini GBIC module with two stacking connectors: RX and TX. RX is the lower connection
point, and TX is the upper connection point. The module is connected to other stacking
units using a stacking cable connection. The top unit’s RX is connected to the lower unit’s
TX. This completes the Ring Topology. The Stacking Connections figure illustrates the
Ring Topology.
