Fast EtherHub 3500 System User’s Guide
Installing the System 2-5
2. Connect one end of the cable to the RJ-45 port of the network
interface card, and the other end to any available (MDI-X)
station port on the hub. Just remember that if you use Port
12MDI-X, the daisy-chain port (12MDI) cannot be used. When
inserting an RJ-45 plug, be sure the tab on the plug clicks into
position to ensure that it is properly seated. Using the hub in a
stand-alone configuration, you can network up to 12 nodes.
IDo not plug a phone jack connector into the RJ-45 port. This may
damage the switch. Instead, use only twisted-pair cables with RJ-45
connectors that conform with FCC standards.
Notes: 1. Make sure each twisted-pair cable does not exceed 100 meters.
2. We advise using Category 5 cable for all network connections to
avoid any confusion or inconvenience in the future when you
upgrade attached devices to Fast Ethernet.
3. You may also connect a device to the switching port located on
hub’s front panel if required. However, be sure you use a
SmartExtender Module that meets your communication requirements.
Refer to
SmartExtender Module
in Chapter 1 for more details.
4. To facilitate troubleshooting, label all network cables to indicate the
attached device and location.
Connecting to the Stack’s Backplane
Plug one end of the FlexBus 3500 stack cable (provided with
the base package) in the Out port of the top hub and the other
end to the In port of the next hub. Repeat this step for each hub
in the stack. Form a simple chain starting at the Out port on the
first hub and ending at the In port on the last hub. Refer to
FlexBus Ports in Chapter 5 for related information.
FHubs in a stack can only be grouped into segments through the
FlexBus 3500 stack cable. You should therefore use the FlexBus ports to
make Out to In connections in a stack.
Hubs in a stack can only be managed by the network management
agent through the stack cable. In a managed stack, you should therefore
use the stack ports to make Out to In connections, and include a
management agent (i.e., a Fast EtherHub-12mi) in the chain.
You can also cascade hubs using the daisy-chain port (Port 12MDI).
However, hubs cascaded using the daisy-chain port cannot be managed by
the management agent. See the next section for details.
