High Speed Interface Configuration Screen (2H23-50R Only)
2H23-50R/2H33-37R User’s Guide 5-49
Current Oper. Mode (Read-only)
This field displays the current operating mode of slots 5 and 6. Depending
on whether a 100BASE-FX or 100BASE-TX Fast Ethernet Interface
Module is installed, this field displays the following:
• With a 100BASE-FX interface: 100Base-FX, 100Base-FXFD (full
duplex), or N/A when the slot is empty.
• With a 100BASE-TX interface: Unknown, 10Base-T, 10Base-TFD
(full duplex), 100Base-TX, 100Base-TXFD (full duplex), or N/A
when the slot is empty.
Desired Oper. Mode (Selectable)
This field allows the user to select the desired operational mode for an
interface in slot 5 or 6. The field toggles between 100Base-FX and
100Base-FXFD (full duplex) when an FE-100FX or FE-100F3 is
installed. Section 5.13.1 describes how to configure a port with an
FE-100FX or FE-100F3.
If an FE-100TX is installed, the field steps to Auto-Negotiation,
10Base-T, 10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD
(full duplex). In normal operation, the port with an FE-100TX installed is
capable of auto-negotiating the operational mode and no further user
setup is required. Section 5.13.2 describes how to manually configure an
FE-100TX.
In Auto-Negotiation, the FE-100TX negotiates to the highest common
denominator of the two interfaces. The order of priority of negotiation is
100Base-TXFD, 100Base-TX, 10Base-TFD, and 10Base-T.
NOTE
In normal operation, the port with an FE-100TX installed
automatically establishes a link with the device at the other end
of the segment without requiring user setup. However, Local
Management provides the user with the option of manually
configuring that port.
