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 10Base- T networks because new hubs and new wiring configurations are necessary.
Follow the guidelines below when planning your 100Base-TX network con- figuration:
❏100Base-TX supports a maximum cable length (distance from a network station to the hub) of 100 meters.
❏The total network diameter (the maximum cable distance between any two stations on the network) is 205 meters.
❏Because 100Base-TX sends signals 10-times faster than 10Base-T, the collision window (the time during which the network can detect a collision between packets) is reduced to one-tenth the duration of the 10Base-T collision window, making the maxi- mum network diameter smaller.
❏Only two hubs can be cascaded together (in a repeater envi- ronment, 100Base-TX allows only a single layer of cascaded hubs). See Figure 2-1.
