    Prompt

    Description

    OK

    Registers settings but does not save them in nonvolatile memory (NVM). A reset command returns to previously saved settings.

    Save

    Saves all settings (including ones not on that screen) to NVM. This is the same as Save Configuration in the Special Functions screen.

    Save ALL APs

    To save the AP installation configuration information to all APs with the same WLAN Service Area. This option saves the configuration changes for the current AP on the Known APs table to update their configurations and reset after the configuration has been modified. Users can perform this option only among the same hardware platforms and same firmware versions. Example: AP-3020 running FW 4.01-xx.

    Cancel

    Does not register settings changed in a screen.

Entering Admin Mode

The UI defaults to User mode, allowing read-only access to the AP's functions (view statistics, for example). Switching to Admin mode provides access to configuration menus and allows you to configure the AP.

To enter Admin mode requires the administration password. To enter Admin mode, do the following:

  1. Select Enter Admin Mode from the Main Menu. The AP prompts for the administration password:
  2. Enter System Password:
  3. Type the default (case sensitive) password:

  1. Select Set System Configuration from the Main Menu.
  2. Select Telnet Logins.
  3. Press the space bar or left/right arrow to toggle between Enabled and Disabled.

Configuring for Dial-Up to the UI

A dial-up connection requires a straight-through Ethernet cable between the modem and the AP. The remote PC requires a modem and a communication program, such as HyperTerminal.

The AP supports modems that use the generic Hayes Smartmodem command set. The AP uses Hayes commands and is capable of working with various modems of 19200 baud or faster. 3Com does not support modems the company has not qualified.

The following modems qualify to work with the AP:

Configuring The Serial Port

To enable and configure the serial port connection on the AP:

  1. Select Set Serial Port Configuration from the Main Menu.
  2. Set the Port Use parameter to PPP.
  3. Set the Modem Connected parameter to Yes.

Configure the other settings as required on the AP. The table below explains the other settings.
