CHAPTER 3
Intel Express 100BASE-T4 Stackable Hub
Unit Numbering Convention
When Express Hubs are stacked, cascaded, and powered, they are
assigned “unit” numbers that are stored in the hub’s nonvolatile
memory. Hub numbers are assigned according to a hub’s physical
location in the stack. The NMM assigns numbers from the top down—
the hub at the top of the stack is numbered 1, the hub below hub 1 is
numbered 2, and so on.
NOTE
A stack of Express Stackable
Hubs can contain a maximum
of six hubs.
In a fully equipped stack, hubs are assigned numbers 1 through 6. You
can identify the unit numbers of the hubs in the stack using network
management software such as Intel LANDesk® Network Manager.
As you build your stack to include more hubs, each hub you add is
assigned a unit number according to its position in the stack after the
NMM is reset or the stack is renumbered through network management
software.
Partitioned Ports
When the Express Stackable Hub detects a large number of consecutive
collisions on a port, it automatically disables, or partitions, that port.
These collisions often occur due to excessive traffic or a
malfunctioning port or network adapter. After the problem is corrected,
the port is automatically re-enabled.
