System Password Extras
Older system password
If you do not know the system password at a site, you will run into some difficulty using the
procedure "Remove on One of Many Units" in Removing a System Password, on p. 169. Table
10–2 on p. 169, shows that reports of “Yes; set.” or “No; set.” indicate that the system password
on the unit is not current.
If a unit reports “Yes; set.” or “No; set.”, run a Maintenance Session to update security on the unit,
as explained in Updating Security on a Multi-Media Unit, on p. 131; or in part 3 of Changing the
System Password, Part 1 (of 3): Using Admin, on p.
168.
When there are many Multi-Media units in a Rapid Eye system
What you want to avoid when there are many Multi-Media units in your Rapid Eye system, is to
avoid changing the system password then updating security on only a few units. Doing so
repeatedly, to different unit subsets, serves no security purpose and can lead to unnecessary
confusion, should repair or sale of units occur. Changing a system password means you need to
update the security on every unit in your Multi db.
Using another Multi central database
Using other Multi dbs to run your system can be considered only for:
• Troubleshooting new installations before a system password is added
• Databases using identical system passwords.
After a system becomes established and a system password is added to your system, Honeywell
does not recommend using many Multi databases.
Honeywell cannot recommend using many databases for the same unit(s) if the Multi dbs
use different system passwords. System passwords should match on all Multi dbs.
What to avoid
The warning above means that using the LVP utility to connect to units protected by the system
password of in another Multi database is an abuse of system function and could jeopardize your
organization’s ability to respond to alarms and to requests for video clips/stills. See also

Security Considerations, on p.

Replacing a Unit
New unit
When you replace a Multi-Media unit at a site with a fresh, factory unit, the factory unit’s “last valid
password” (LVP) is blank.
When a system password is in use: LVP
If you replace a Multi-Media unit and your Multi database is set to a system password (see
System
Password), you need to use the LVP utility to match the site definition to the blank password on
the unit.
