Fast EtherHub-12s User’s Guide

Note: If the hub displays a high collision rate, check to see if any of the connected devices are malfunctioning or if a loop has been formed in your network connections. Otherwise, you may need to reconfigure your network to balance the traffic load.

Partition

Shows if the port has been isolated from the network

Indication Indicates port has been partitioned due to an abnormal network condition. Port is in good condition.

A port is temporarily partitioned when a line error or too many collisions are detected on the attached segment. While it is automatically partitioned, the port continues to receive data from the segment. However, data is not transmitted onto the segment. When the problem is corrected or a valid data packet is received through the port, the port is automatically reconnected. When partitioning occurs, the port’s corresponding Partition LED will be continually lit (RED light). Otherwise, this LED should be OFF (unlit).

Notes: 1. When a long run of collisions occur on the cable connected to a hub port (i.e., 64 collisions), that port is automatically partitioned by the hub. It is automatically reconnected when a collision-free data packet at least 512 bits long (i.e., a minimum size legal packet) passes through the port.
