Managing the Hub 2-37

The SmartSwitch 2000 Chassis View

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.
