1 Introduction FriendlyNet FH100TX8 and FH100TX16 Thank you for purchasing the Asanté FriendlyNet FH100TX8 or the FriendlyNet FH100TX16 Fast Ethernet Hub. The FH100TX8 and FH100TX16 Fast Ethernet Hubs are 100Base-TX multiport repeaters designed for networks using Unshielded Twisted Pair (UTP) Category 5 cable or Shielded Twisted Pair (STP) cable.
Introduction Network Reliability To ensure network reliability, each hub monitors their ports for signal quality and automatically disconnects stations transmitting excessive noise, reconnecting them when the problem is resolved. The hubs automatically truncate data packets that exceed the maximum length for IEEE 802.3u, preventing a device from blocking the network by transmitting continuous data streams or extra long packets.
2 Installation Installation of the FH100TX8 or FH100TX16 hub consists of the following steps: ❏ Plan your 100Base-TX network. ❏ Review cabling and voltage requirements. ❏ Connect your hub to network devices. ❏ Mount the hub in an equipment rack or prepare it for desktop placement. Planning 100Base-TX Networks 100Base-TX networks need to be planned out slightly different from 10BaseT networks because new hubs and new wiring configurations are necessary.
Installation Figure 2-1 Sample 100Base-TX network layout Cabling Requirements 100Base-TX requires data-grade (Category 5) UTP (Unshielded Twisted Pair) cable. ▲ Important: Some installations have Category 5 cabling but do not have wall outlets and/or wiring closet punch-down blocks that meet Category 5 requirements. 100Base-TX requires that all wiring and accessories meet EIA/ TIA 568B specifications for proper operation.
FriendlyNet Fast Ethernet Hub User’s Manual Connecting Network Devices Before you connect the hub to other devices, review the following guidelines: ❏ Make sure the network cable length is less than 100 meters. ❏ Use a straight-thr ough twisted pair cable to connect ports to network devices. ❏ When connecting two hubs together (cascading hubs), make sure that the link between them is not longer than 5 meters.
Installation Hub to Hub Connection (Cascading Hubs) To connect two hubs together, follow the instructions and diagram below. ▲ Important: When using the uplink port on a hub, that hub’s last port (port #8 on the FH100TX8, port #16 on the FH100TX16) CANNOT be used. A FriendlyNet Fast Ethernet Hub’s uplink port and its last port cannot be used simultaneously. ❏ Do NOT connect two hubs’ uplink ports together. ❏ Do NOT use a crossover cable with the uplink port.
FriendlyNet Fast Ethernet Hub User’s Manual Multiple Hub and Station Configuration To connect two FriendlyNet Hubs and multiple Fast Ethernet network stations, follow the guidelines and diagram below. ▲ Important: Your Fast Ethernet network configuration must comply with the IEEE 802.3u standard. ❏ The maximum number of 100Base-TX hubs between any two network stations is TWO. ❏ The maximum cable distance between any two stations on the network is 205 meters.
Installation Mounting the FriendlyNet Hub The FriendlyNet Fast Ethernet Hub can be mounted in a standard 19-inch equipment rack or it can be prepared for desktop placement. This section describes both mounting scenarios. Equipment Rack Placement To mount the hub in an equipment rack: 1 Mount one rack-mounting bracket (provided) on each side of the hub using the six screws provided. See Figure 2-5. Figure 2-5 Installing rack-mounting brackets 2 3 Place the hub in the equipment rack.
3 LED Indicators The FriendlyNet FH100TX8 and FH100TX16 each have LEDs that represent the following: ❏ Power ❏ Partition ❏ Link/Receive ❏ Utilization % Figure 3-1 FriendlyNet FH100TX8 Fast Ethernet Hub LEDs Figure 3-2 FriendlyNet FH100TX16 Fast Ethernet Hub LEDs Page 3-1
LED Indicators Power The gr een PWR (power) LED on the hub’s front panel illuminates when the hub is turned on and receiving power. Partition The yellow Partition LEDs, associated with each port, illuminate if a port has been partitioned. A port will automatically disconnect a segment if there are excessive collisions (two or more stations on the network attempt to transmit packets simultaneously). The segment will be reconnected when the collisions have subsided.
A Troubleshooting Monitoring LEDs The following table describes how to troubleshoot problems with your network and/or the hub by monitoring the hub’s LEDs. Problem Action Power LED is off ✔ Make sure the power adapter is connected to the power outlet and is properly inserted into the power connector on the hub. ✔ Determine if the outlet is functional by plugging another device into the receptacle.
Troubleshooting Problem Action Link/Receive LED is off ✔ Make sure the hub is powered on. ✔ Make sure the device on the other end is powered on. ✔ Make sure the proper cabling is used between the device and the hub (refer to the cable guidelines specified in Chapter 2). ✔ Make sure the correct cable is properly connected to the hub and to the network device. ✔ Make sure the cable does not exceed recommended length (100 meters).
