Power | Amber. The Power LED lights up when the Switch is pow- |
| ered on. |
Link/Act | Green. The Link/Act LED serves two purposes. If the LED |
| is continuously lit up, the Switch is successfully connected to |
| a device through the corresponding port (1 through 8). If the |
| LED is flickering, the GigaSwitch is actively sending or |
| receiving data over that port. |
FD/Col | Green. The FD/Col LED also serves two purposes. If this |
| LED is lit up continuously, the connection made through the |
| corresponding port is running in Full Duplex mode. If the |
| LED flickers, the connection is experiencing collisions. |
| Infrequent collisions are normal. If this LED flickers too |
| often, there may be a problem with your network. |
10/100 | Amber. The 10/100 LED lights up for any port when that port |
| is operating at 100Mbps. If the LED is off while the network |
| is operating, the port is operating at 10Mbps. |
1000 | Amber. The 1000 LED lights up when the Gigaswitch port is |
| operating at 1000Mbps. If the LED is flickering, data is |
| being transmitted through the port. |
1000 Link/Act | Green. The 1000 Link/Act LED lights up when the Gigabit |
| port is operating at 1000Mbps. |
1000 FD/Col | Green. The 1000 FD/Col LED lights up continuously when |
| the switch is operating at 2000Mbps and flickers when expe- |
| riencing data collisions. |

Planning Your Network
Overview
Building a Gigabit network involves more topology rules in addition to the 10BaseT/100BaseT network rules. These rules specify distance limitations and cabling specifications. Data loss, collisions, and other network problems causing down time are likely to occur if the rules below are not followed.
•Use UTP Category 5 (or better) Ethernet cabling with four pairs of wires and
•Use the chart below to position your switches, hubs and workstations.
From | To | Maximum Distance |
Switch | Switch or Hub* | 100 meters (328 feet) 1 |
|
|
|
Hub* | Hub* | 5 meters (16.4 feet) 1 |
|
|
|
Switch or Hub | Workstation 1 | 100 meters (328 feet) 1 |
|

*Hub refers to any type of 100Mbps hub, including regular hubs and stackable hubs. A 10Mbps hub connected to another 10Mbps hub can span up to 100 meters (328 feet).
•No more than two hubs should be uplinked in a row in a Fast Ethernet net- work. A set of stacked hubs, which must be stacked with a stacking cable, counts as one hub or node on the network.
•In Fast Ethernet networks, your 10/100 Switch acts as a repeater, regener- ating data signals before passing them on to the next device. Passive hubs do not function as repeaters.
Switches Versus Hubs
Your Workgroup GigaSwitch boosts your network performance several times over, conserving your time, money and resources. The scalability of your Switch, its full duplex data transfer and dedicated bandwidth all contribute to maximizing efficiency in your Fast Ethernet network.
Your Switch’s 10/100 feature gives you a key advantage over other forms of networking by upgrading
