Fast EtherHub-12se User’s Guide

These Fast EtherHubs support the following basic system safeguards:

∙This hub features automatic partitioning and reconnection, jabber lockup protection, and automatic polarity detection for network cabling.

∙With automatic partitioning and reconnection, any port is automatically isolated if excessive collisions occur on it. When the collision rate subsides, the port is automatically reconnected.

∙With the jabber lock-up function, the hub automatically stops transmission of abnormal Ethernet frames that may cause data loss for all network users. (Jabber refers to abnormal Ethernet frames which are much too long and may come from a malfunctioning Ethernet card.)

∙With automatic polarity detection, the hub recognizes and adjusts for attached cable assemblies which may be wired with incorrect polarity on the receive pair.
