Password Recovery Process
If you have lost the switch’s manager username/password, but
password-
recovery
is enabled, then you can use the Password Recovery Process to gain
management access to the switch with an alternate password supplied by
ProCurve.
N o t e
If you have disabled
password-recovery
, which locks out the ability to recover a
manager username/password pair on the switch, then the only way to recover
from a lost manager username/password pair is to use the Reset+Clear button
combination described under “Restoring the Factory Default Configuration”
on page 2-25. This can disrupt network operation and make it necessary to
temporarily disconnect the switch from the network to prevent unauthorized
access and other problems while it is being reconfigured.
To use the
password-recovery
option to recover a lost password:
1. Note the switch’s base MAC address. It is shown on the label located on
the upper right front corner of the switch.
2. Contact your ProCurve Customer Care Center for further assistance.
Using the switch’s MAC address, the ProCurve Customer Care Center will
generate and provide a “one-time use” alternate password you can use
with the to gain management access to the switch. Once you gain access,
you can configure a new, known password.
