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.
100BASE-FX device. The Fast EtherHub-12se has 11 RJ-45 station ports, of which Port 12 can serve as either a station port or a daisy-chain port (depending on the port’s switch setting).
Fast EtherHub-12se User’s Guide model you purchased) to connect any compatible network device to the TX/RX jacks on the fiber optic port. Note: The EH3012-TF-SC provides an SC-type fiber connector. The EH3012-TF-ST provides an ST-type fiber connector. Making RJ-45 Connections 1.
Both of these methods are described in this section. Simplified Cable Length Constraints The Fast EtherHub-12se is a Class II repeater. IEEE recommends that Class II hubs be limited to a cascade of two hubs. The simplest rule is that workstation connections be limited to 100 meters for twisted-pair cabling and 112 meters for fiber optic cabling, and that interhub cabling be limited to 5 meters.
Fast EtherHub-12se User’s Guide Precise Cable Length Budgeting If you plan on installing a network for a small office, it may not be convenient to place hubs within 5 meters of each other, and then run up to 100 meters of cabling for each end user.
Fast EtherHub-12se User’s Guide On the other hand, if two hubs are connected via 100m of fiber optic cabling, then the total length of remaining cabling that can be used to connect two end- nodes to hub 1 and 2 respectively is 367m - (2 x 80m) - (0.9 x 100) = 117m.
Fast EtherHub-12se User’s Guide Verifying System Operation Verify that all attached devices have a valid connection. The hub monitors link status for each port. If any device is properly connected to the hub and transmitting a link beat signal, the Link indicator lights up for the corresponding port.
Chapter 3: Configuring the Network The Fast EtherHub-12se allows great flexibility in configuring your network. You can use it in a stand-alone or multiple hub configuration. Moreover, this hub also provides a fiber optic port which can be used to connect to any compatible 100BASE-FX device (e.g., a switch or router).
Fast EtherHub-12se User’s Guide Using the RJ-45 Daisy-Chain Port You can easily connect to another hub via the MDI daisy-chain port (Port 12). 6LPSOLHG &DEOH /HQJWK &RQVWUDLQWV When using as described in Chapter 2, the inter- hub cable length is 5 meters. Figure Chapter 3:-2 shows a sample configuration.
Fast EtherHub-12se User’s Guide Precise Guidelines for Configuring Multiple Hubs A detailed formula for calculating maximum cable length was provided in the 3UHFLVH &DEOH /HQJWK %XGJHWLQJ section on in Chapter 2. This formula stated that the maximum length of cabling that can be run from end-node to end-node is: ≥...

Fast EtherHub-12se User’s Guide Figure Chapter 3:-4 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 cable segment. 2. To control the number of hubs in a path, we recommend that one hub be used to connect to several other hubs.
Chapter 4: HardwareReference This chapter describes the hardware features of the Fast EtherHub-12se. For easier management and control of the hub, familiarize yourself with the display indicators and ports. This hub includes 11 RJ-45 MDI-X station ports, of which Port 12 can also serve as an MDI daisy-chain port. In addition, it...
