3. Install the replacement EM2100 hardware as described in: Installation on page 21.
4. Reconnect the networking cables from the remaining, functioning EM1100 as shown in:
EM2100 and EM1100 Autosync — Ethernet Cabling on page 55.
5. Using the SetNetGo interface, connect to the EM1100 Management IP address.
6. Update the software on the EM1100 as described in: Update the ARAMCentral Software
on page 71.
7. From SetNetGo on the Secondary appliance, select Software and then Autosync.
8. If the EM1100 is not already configured as a Secondary appliance, configure it as
described in: Configure the Secondary Appliance on page 57.
9. Configure the replacement EM2100 as the Primary appliance as described in: Configure
the Primary Appliance on page 56. If not already configured as a Primary, which is the
default (shipped) setting.
10. Wait for Autosync to start and for normal operation to resume.
The AIVs automatically reconnect to the new Primary appliance.
The queue, configuration, and map data on the new Primary is identical to that of the old
Primary, prior to failure. Depending on exact network configuration, it takes between 1-3
minutes for AIVs to reconnect and resume operation.
You can now safely remove the original (failed) Primary appliance from the rack without caus-
ing disruption to the fleet. The following considerations apply:
The new Primary operates on the same Fleet IP as the old Primary appliance. Do not
l
reconnect the old Primary to the network without first reconfiguring it. Doing so might
cause a network IP conflict.
The failed Primary has the queue file, which is no longer current. Before putting the
l
failed Primary back into service, you should manually clear the queue. See Manually
Clearing (Flushing) the Entire Queue on page 70.
