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. For an
EPC400 node or an EPC800 node you must use a CBLG106 cable and a CBL1912 adapter.
In the case of an EPC1200/EPC1200A node, in order to stop the RI signal to which the
node is sensitive, you must use a CBL2101 cable in addition to the CBLG106 cable and the
CBL1912 adapter.
A CBL2101 cable is generated automatically for each EPC1200 and EPC1200A node of a
configuration containing a 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.
