Hub Maintenance Tasks; Testing The Hub Only; Clearing A Password For The Ascii Console - HP J3188A Installation And Reference Manual

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.
To clear the password, follow these steps:
1. Verify the hub has powered-up, passed power-on test, and that the System
LED is lit.
2. Press the Password Reset button on the back of the hub for 10 seconds.
