Slave Hub Role
Slave hubs supply the stack with additional ports (12/24) and an addi-
tional expansion module slot. Slave hubs can be positioned above or
below the master hub. The 8112-01-S and 8124-01-S can also act as stand
alone unmanaged hubs.
Hub ID
The master hub and slave hubs can be positioned anywhere in the stack
and each hub’s ID is automatically assigned based on its position (in the
stack).
Segmenting Hubs
CenturyStack hubs can isolate one or both segments (10 Mbps and 100
Mbps segments) from the other hubs in a stack. When a segment is
isolated it does not repeat to the other segments in the hub or to other
segments in the stack.
Connecting Devices
The dual speed CenturyStack can connect to 10Mbps, 100Mbps, or
10/100Mbps devices due to its auto sensing capability. CenturyStack will
auto sense the connected port speed and set its port to match the speed of
the connected port.
Cables
CenturyStack ports accept Cat 3, 4 and 5 cables with RJ-45 connectors
for 10Mbps connections and Cat 5 cables with RJ-45 connectors for
100Mbps connections. The maximum length of cables, between hub and
workstations is 100 meters. The maximum length of cables, between hub
and hub is 5 meters for 100Mbps connections and 100 meters for
