N o t e
The alternate password provided by the ProCurve Customer Care Center is
valid only for a single login attempt. You cannot use the same "one-time-use"
password if you lose the password a second time. Because the password
algorithm is randomized based upon your switch's MAC address, the pass­
word will change as soon as you use the "one-time-use" password provided
to you by the ProCurve Customer Care Center.
