Console Cabling Requirements
Usage cases DCKU119–2000
The Console Concentrator is used with:
•
a Powerconsole whatever is the number of nodes in the Escala EPC configuration. See
Figure .
•
a Cluster Console if the number of nodes is more than two nodes. See Figure 17.
If there is a cluster Hub (case of dedicated administration network), the Console
Concentrator is connected to it. Otherwise, the Console Concentrator is connected to the
Customer’s Ethernet Network. In that case, if the customer’s network is COAXIAL THICK or
COAXIAL THIN then the Customer is in charge of connecting the Console Concentrator to
his network with his own cable (As usual for all the Escala platforms).
The nodes (S1 port) are connected via serial cables to the Console Concentrator. A cable
CBLG197-2000 (Cable Remote RS232 (25M-25F) is provided depending on the number of
nodes ordered.
For EPC400/430 a CBL1912 is connected to the CBLG197-2000.
For EPC440/1200/1200A/2400 the cable P/N40H6328 delivered with the node is connected
to the CBLG197-2000.
The cable CBLG197-2000 is connected to the Console Concentrator.
One Console Concentrator is needed for configurations up to 8 nodes. Once the nodes (S1
port) are connected to the Console Concentrator, the console ports of the two FDDI
LinkBuilder hubs can be connected onto the Console Concentrator, if there are two serial
ports left on the Console Concentrator. To do this, the two small RS232 adapter cables
provided are used to plug the serial link on the FDDI equipment. This also applies to the
Fast Ethernet Switch and the Gigabit Ethernet Switch (only one serial port on the console
concentrator is required to connect a switch).
Several Console Concentrators are necessary for large configurations.
Cascading Console Concentrators through a serial line is not operational. Therefore, the
Console Concentrators must be connected to the Cluster Hub or the customer’s LAN.
