10.
Save the PM configuration, by clicking one of the following buttons:
a.
Create
b.
Create Device & Outlets
c.

11.
If you have not uploaded the PM device during the previous step, select:
“Admin” tab > “Devices” menu.
The devices list appears. The PM device and possibly, the device to which
it is attached will have indications in the “Upload” columns indicating
that an upload is required.
12.
Click on the checkbox next to the listed devices requiring uploads.
13.
Click the “Upload” button near the bottom of the form, and wait for the
upload to take place.
Note:
If you create an admin user with access restricted to a PM device only,
and such a user subsequently logs onto the APM and uploads the PM device,
the parent device will also be uploaded. This happens even if the parent
device is specifically
not
checked in the upload menu.
Redundant (Fault Tolerant) Configuration
Note:
This feature is not supported on the APM E2000.
Heartbeat, Redundancy, Data Synchronization, and Failover support provides
the ability to back up and restore an APM 2500 or APM 5000 system with
little or no downtime in the event of a failure of a primary APM. By using the
heartbeat protocol in conjunction with network RAID, a redundant APM
automatically takes over device and console management in the event of a
failure of the primary APM or its Ethernet connection.
A heartbeat signal between a primary and secondary APM verifies that the
primary APM is up and running. If the heartbeat signal is not received from
the primary APM for a predetermined interval (5 seconds by default), the
primary APM is assumed to be down and the redundant APM takes over.
When the primary APM is brought back up, the secondary APM fails back
and synchronizes data with the primary APM.
