Client Hub Role

Client hubs supply the stack with additional ports (12/24) and an addi- tional expansion module slot. Client hubs can be positioned above or below the master hub. The LH8112A-S and LH8124A-S can also act as stand alone unmanaged hubs.

Hub ID

The master hub and client 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

The 10/100 Managed 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 10/100 Managed Hub can connect to 10Mbps, 100Mbps, or 10/100Mbps devices due to its auto sensing capability. The 10/100 Managed Hub will auto sense the connected port speed and set its port to match the speed of the connected port.

Cables

The 10/100 Managed Hub ports accept Cat 3, 4 and 5 cables with RJ-45 connectors for 10Mbps connections and Cat 5 cables with RJ-45 connec- tors 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
