To set your desired operational mode:
1. Click on the Desired Operational Mode combo box to display the menu of
available options; click to select the operational mode you wish to set.
For 100Base-TX ports, the available options are:
10Base-T — 10 Mbps connection, Standard Mode
10Base-T Full Duplex — 10 Mbps connection, Duplex Mode
100Base-TX — 100 Mbps connection, Standard Mode
100Base-TX Full Duplex — 100 Mbps connection, Duplex Mode
Auto Negotiation — the operational mode will be dynamically set based on
the modes selected in the Advertised Abilities field (where both link partners
are auto-negotiating) and the speeds and modes supported by the attached
device.
For 100Base-FX ports, options are:
100Base-FX — 100 Mbps connection, Standard Mode
100Base-FX Full Duplex — 100 Mbps connection, Duplex Mode
2. If you have selected Auto Negotiation (for 100Base-TX ports only), use the
Advertised Abilities field to select the operational capabilities you wish to
advertise to the port’s link partner. If both link partners will be
auto-negotiating, be sure there is at least one mutually-advertised operational
mode, or no link will be achieved.
3. Click on the Apply button to save your changes. Click on the Refresh button
to display the new settings. Note that it may take a few minutes for mode
changes to be completely initialized, particularly if the link partners must
negotiate or re-negotiate the mode; you may need to refresh the window a few
times before current operational data is displayed.
TIP
The selected Advertised Abilities only come into play when both link partners are
auto-negotiating; if only one link partner is set to auto-negotiate, that node will establish a
link at whatever mode its partner is set to, even if that mode is not currently being
advertised.
