PASSWORD RECOVERY
If you mislay a device's password, they can be recovered. To obtain the recovery password you must contact
the Contact Centre and supply the Serial Number and its Security Code. The Contact Centre will use these
items to generate a Recovery Password.
The security code is a 16-character string of upper case characters. It is a read-only parameter. The device
generates its own security code randomly. A new code is generated under the following conditions:
●
On power up
●
Whenever settings are set back to default
●
On expiry of validity timer (see below)
●
When the recovery password is entered
As soon as the security code is displayed on the LCD, a validity timer is started. This validity timer is set to
72 hours and is not configurable. This provides enough time for the contact centre to manually generate and
send a recovery password. The Service Level Agreement (SLA) for recovery password generation is one
working day, so 72 hours is sufficient time, even allowing for closure of the contact centre over weekends
and bank holidays.
To prevent accidental reading of the IED security code, the cell will initially display a warning message:
PRESS ENTER TO
READ SEC. CODE
The security code is displayed on confirmation. The validity timer is then started. The security code can only
be read from the front panel.
4.4.1
PASSWORD RECOVERY
The recovery password is intended for recovery only. It is not a replacement password that can be used
continually. It can only be used once – for password recovery.
Entry of the recovery password causes the IED to reset all passwords back to default. This is all it is
designed to do. After the passwords have been set back to default, it is up to the user to enter new
passwords. Each password should be appropriate for its intended function, ensuring NERC compliance, if
required.
