Honeywell K14392V1 manual Last Valid Password, If a Used Unit Comes from Another Multi System

Security for a Multi-Media System

Last Valid Password

Tip

The scenarios described below are exceptional; they only apply when dealing with re-entry of information in a site definition for used units.

Last valid system password

When your Multi-Media system administrator (Multi SA) adds a site definition, the “last valid password” (LVP) entry for that site remains blank in your Multi central database (Multi db). When a system password is added, this database entry is updated along with the unit. There are situations where a discrepancy can occur between the system password held by a unit and the system password entry in the Multi db. An LVP utility is available to resolve the discrepancy.

The LVP utility may need to be used if you:

•Obtain a “used” unit, from another organization’s Multi system. A Multi-Media unit may still be protected by a system password. You may need to contact the other organization’s Multi SA.

- or -

•Delete a site definition, by mistake. The Multi-Media unit of a mistakenly deleted site definition is (usually) protected by a system password. Please note that, if a site definition is deleted by mistake, but no system password has been set, you can disregard using the LVP when re- entering the site.

The LVP utility enters the last valid password (the password protecting the unit) in the Multi db.

Entering a site definition for an “other” unit

If you have obtained a unit from another user and you suspect that the system password on that unit was not removed, use the next procedure.

If A Used Unit Comes from Another Multi System

1.Create a site definition (see Naming / Renaming a Site on p. 24).

2.Use View to run a Maintenance Session. If an error message is produced, contact the previous owner to obtain the unit’s system password on the previous owner’s system.

3.Having obtained that password, use Admin to update your site definition.

4.Click LVP (last valid password). A Match the Password at Unit dialog box appears. See figure 10–6, below.

5.Type the password obtained from the previous owner. For clarity, figure 10–6shows a one- character password; Honeywell does not recommend using one-character passwords.

6.Confirm the password.

7.Click Save and Close.

8.Using View, start a Maintenance Session, to register the site.

Failure to run a Maintenance Session

If the site cannot be accessed, you have either:

•Obtained an incorrect system password from the unit’s previous Multi SA/owner.

•Incorrectly typed the password in the LVP utility.

•A Maintenance Session is being run by another user. Try to run a Live Session instead.
