Hub Maintenance Tasks

Hub Maintenance Tasks

There are several hub maintenance tasks you can perform. They include:

■testing the hub only

■clearing a password from the ASCII console

■running connectivity tests

Each of these tasks is described in the following sections.

Testing the Hub Only

If you believe that the hub is not operating correctly, remove and reinsert the power cord for that hub. This procedure will cause the hub to complete its power-on self-test. If any error conditions exist in the hub, the LEDs should display the condition.

Clearing a Password for the ASCII Console

You can use the Password Reset button to clear a forgotten console password that was previously configured on the hub. The password is configured from the ASCII console.

Troubleshooting
