6-4 CHAPTER 6: PROBLEM SOLVING

Check the settings on your terminal or emulator. The parity must be set to ‘none’, the stop bit ‘1’ and the character size ‘8’. The management facility’s autoconfiguration works only with speeds from 1200 to 19200 baud.

The Telnet management station cannot access the device. Check the hub’s IP address, subnet mask and default router are correctly configured, see “Giving the Hub an IP Address” on page 4-7, and the device has been reset. Ensure that you enter the IP address correctly when invoking the Telnet facility.

You forget your password.

Another user with security access level can log in using VT100, delete your user name, and create a new user name, with a new password for you, see “Configuring Users” on page 5-17.

If you know your community string, you can log in using Quick Config Manager and initialize the device, see “Initializing the Hub” on page 4-11. This returns all configuration information, including passwords, to the default values.

Alternatively, another user with security access level can log in and initialize the device.

Problems When Using an IP/IPX-based Management Application

The IP/IPX-based management application cannot access the device. Check that:

■The hub’s IP address, subnet mask and default router are correctly configured, see “Giving the Hub an IP Address” on page 4-7.

■The hub has been reset, see “Resetting the Hub” on page 4-11.

■The hub’s IP address is correctly recorded by the IP/IPX-based management application. For information on how to do this, refer to the documentation accompanying the application.

Traps are not received by the IP/IPX-based management application. Check that the address of the management station is entered in the hub’s trap table, see “Setting Up Traps” on page 5-12.
