6-5Console Cabling Requirements
Examples of Use
System Console
The System Console (ASCII terminal) is offered in the following cluster configurations:
• Uni-node Escala EPC: the system console is attached through serial port S1 of the node.
• Two–node Escala EPC: the System Console can be used alone. In this case the System
Console is connected to a node’s S1 port, as shown on Figure 10. There can be two
System Consoles, one per node, each one connected to a node’s S1 port.
• Escala EPC configuration with Console Concentrator: the System Console can be used
with a Cluster Console or a PowerConsole. In that case, the System Console is
connected to a serial port on the Console Concentrator, as shown on Figure 11.
Note: A 9M/25M RS232 cable (CBL1912) shipped with any Escala CPU drawer (EPC800
node, EPC400 node, EPC1200/EPC1200A node), is connected to the node’s S1
serial port (9F).
Graphics Display
The Graphics Display is offered in the following cluster configurations:
• In a uni-node Escala EPC, the Graphics Display can be ordered in lieu of a System
Console (an ASCII terminal)
• For a two–node Escala EPC, there can be a System Console attached to a first node and
a Graphics Display attached to the second node, or conversely.
• The latter applies to any two-node Escala EPC used in disaster recovery architecture.
• EPC800 node: there is no Graphics display.
• MATROX board can run on EPC400 configuration with a PCI expansion drawer.
• The Fibre DAS management requires a graphical terminal.
Note: An Ethernet cross–over cable (CBLG161–1900) is provided with the Graphics
Display. It can interconnect the two nodes by using the integrated Ethernet boards.
This Ethernet link allows to access the second node from the graphical terminal of
the first one.
