Chapter 5: Local Management
Advertised Ability (Selectable)
During auto-negotiation, the FE-100TX informs the device at the other end of the segment what its capabilities are. The capabilities of a port with an FE-100TX installed are 10BASE-T, 10BASE-TFD (full duplex mode), 100BASE-TX and 100BASE-TXFD (full duplex mode). In normal operation, with all capabilities enabled, the FE-100TX “advertises” that it has the ability to operate in any mode. The Network Manager may choose to set up the port so that only a portion of the available capabilities are advertised and the others are disabled. For example, only 100BASE-TX and 100BASE-TXFD might be enabled so that only devices that operate at 100 Mbps can communicate with that port. Section 5.11.4 describes how to enable or disable advertised modes.
5.11.1Configuring an FE-100FX Interface or a Port 7 or 8 FE-100FX/F3 Interface
Whether configuring the fixed interface (ports 1–6) or an FE-100FX or FE-100F3 installed in port 7 or 8, the procedure is the same. The port must be manually set to operate in the same mode as the device at the other end of the connected segment. Use the Desired Oper. Mode field to set the FE-100FX or FE-100F3 ports. This field toggles between 100BASE-FX and 100BASE-FXFD (full duplex). To set the active technology through Local Management, proceed as follows:
1.Use the arrow keys to highlight the Desired Oper. Mode field.
2.Use the SPACE bar to select 100Base-FXor 100Base-FXFD(full duplex).
3.Press ENTER. The port now operates in the chosen mode.
4.Use the arrow keys to highlight the SAVE command. Press ENTER. The message “SAVED OK” displays and Local Management saves the changes to memory.
5.11.2 Configuring an FE-100TX Interface
In normal operation, a port with an FE-100TX interface automatically establishes a link with the device at the other end of the segment and no user setup is required. Section 5.11.3 and Section 5.11.4 provide instructions to manually configure the port with an FE-100TX installed.
