1.9 Phone Home Alarm Reporting
When this UPS is activated for phone home operation and the UPS senses one of
several preselected alarm conditions, the UPS automatically dials IPM’s Field Service or
another designated computer without human assistance and notifies service personnel of a
system problem requiring attention.
Important information downloaded during each phone home event includes:
1) UPS name, ID, phone number and serial number
2) customer ID and phone number
3) list of active alarms.
You obtain the following benefits from this feature:
0.
a. Immediate service personnel notification of site power or UPS problems, even
when the UPS is unattended.
b. Increased availability due to reduced mean-time-to-repair with automatic
notification and complete remote diagnostic capabilities.
c. 24 hours per day, 7 days per week monitoring of unmanned facilities and
locations where operators are unfamiliar with the UPS. Often, service personnel
can take steps to solve a UPS problem remotely before the user is aware that there
is a problem.
An internal modem and a dedicated telephone line are required. Phone Home Alarm
Reporting can be activated only with a Field Service level of password. It is normally done
at the time of startup by a Customer Engineer.
1.10 Dial-Back Security
This security feature is provided to insure system integrity. It prevents “hackers” or
other unauthorized persons from intentionally or unintentionally accessing the UPS database.
Anyone calling the UPS must establish authority through the use of a dial-back password.
The unit will validate this password against up to four passwords stored in nonvolatile
memory. One of the passwords allows direct communication to commence with the UPS.
The other three passwords have associated telephone numbers. If one of these three
passwords receives validation, the UPS logic will hang up and dial back the phone number
associated with that password. When the connection is made, the remote operator must enter
the normal privilege level password for access to the corresponding level of monitoring
diagnostics and controls. In this way high level security is provided because the remote
operator must know the dial-back and access passwords and be calling from the proper
associated phone number.
An internal modem and a dedicated telephone line are required. Dial-Back Security can be
activated only with a Field Service level of password. It is normally done at the time of
startup by a Customer Engineer.
