Page 12: Basic Features
Automatic polarity detection and correction permits automatic adjustment for wiring errors • Plug-and-play operation The Fast EtherHub-8se also supports the following basic system safeguards: • This hub features automatic partitioning and reconnection, jabber lockup protection, and automatic polarity detection for network cabling. - Page 13 Fast EtherHub-8se User’s Guide • With automatic partitioning and reconnection, any port is automatically isolated if excessive collisions occur on it. When the condition is corrected, 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.

Page 17: Simplified Cable Length Constraints
Fast EtherHub-8se User’s Guide Simplified Cable Length Constraints The Fast EtherHub-8se is a Class II repeater. IEEE recommends that Class II repeaters be limited to a cascade of two hubs. The simplest rule is that workstation connections be limited to 100 meters (328 feet) for twisted-pair cabling and that interhub cabling be limited to 5 meters (16 feet). - Page 18 Fast EtherHub-8se User’s Guide However, when setting up these kinds of distributed cascades, you have to be very careful in calculating the maximum length for each node pair. All end- node devices (e.g., workstations or servers) must be within 100 meters (328 feet) of the connected hub when using twisted-pair cabling.

Page 24: Figure 3.3 Cabling Limits For Multiple Hub Configuration
Fast EtherHub-8se User’s Guide Figure 3.3 Cabling Limits for Multiple Hub Configuration Notes: 1. The maximum length for each cable must be determined by calculations for the longest path (i.e., node-to-node connection) that passes through that segment. 2. To control the number of hubs in a path, we recommend that one hub be used to connect to several other hubs. -
