Diagram with Escala S100 and one modem by node
Figure 134 shows an example which is relevant for any Powercluster configuration with an
Escala S100 based PowerConsole 2, though this figure shows a configuration with a
dedicated–administration network. In that case you may have one modem on the
PowerConsole and/or one modem by node. This solution is more safety because in case of
the PowerConsole is out of service you will be able to use RSF facilities.
Figure 134. RMCF04:Remote maintenance: Modem on a PowerConsole (Escala S100) and a
modem by node
Example of Use
The PowerConsole is directly linked to the console concentrator (CS/2600) with a serial line
(RS232). A modem is a board inserted inside the Escala S100.
RSF is installed in a cluster distributed configuration. The PowerConsole is used by the
remote maintenance as the access point to the nodes and the PowerConsole itself.
•
RSF is configured with ”callscarf” module on PowerConsole to interface the remote
maintenance center.
•
RSF is configured with ”cluster” module on every node, enabling the messages sent to
and from the nodes to be relayed by the PowerConsole.
Cabling the Powerconsole to the concentrator allows the management of EPC nodes even
if the dedicated–administration network or the customer’s LAN network is out of order. In
that case, it is assumed that there is a serial port left (e.g. J9) on the concentrator for
connecting the Powerconsole enabling to reach the nodes for service.
