Quick Installation

The Fast EtherHub-12se is a Class II repeater.  It contains 11 100BASE-TX
Fast Ethernet RJ-45 ports, as well as 1 100BASE-FX fiber optic port that
supports connection using standard multimode fiber cable.  The smart design
built into the front display panel provides a friendly interface that simplifies
installation and network troubleshooting.  If you are already familiar with basic
network operations, you should be able to install this hub as described below:

1.

 

Unpack the Fast EtherHub-12se.

2.

 

Find a location close to the network devices you need to connect, and within
easy reach of an electrical outlet.

3.

 

Mount the hub on a desktop or any other flat surface.  If you are installing
multiple hubs, you can stack them on top of each other (after attaching the
foot pads), or install them in an standard EIA 19-inch rack.

4.

 

Connect servers or workstations to the RJ-45 MDI-X station ports.  Use
100

W

 Category 5 STP or UTP cable to connect to the hub, and be sure the

length of any individual twisted-pair connection does not exceed 100 meters.

5.

 

You can connect the hub’s 100BASE-FX port to a workstation, another hub,
or to a collapsed backbone (e.g., a 100 Mbps switch).  Use 50/125  

m

m or

62.5/125 

m

m fiber optic cables with SC or ST connectors to connect to the

hub. Assuming the maximum cable length of 100 meters is used to connect
various devices to the hub with twisted-pair cable, then the maximum length
you can run a fiber optic link depends on the device type you want to attach
to the hub, as shown in the following table:
