Remote Maintenance
Using Two Modems
Two modems are provided with every 2-node configuration which does not include any
console concentrator. When extending a uni-node configuration with an additional node, an
external modem is added. An original uni-node EPC RT model is provided with a modem
integrated in the CPU drawer.
In any EPC400 configuration, there should be at least one node with an integrated modem.
CAUTION:
DAS management can be performed either with DAS manager tool or with
ArrayGuide application (Navisphere for DAS57xx). In the former, there is a need to
connect a serial cable between a node and a DAS service processor, which requires
a serial port free on the node (S2 on ECP400). As conflicts on serial ports may
happen, and as Array Guide can only be exerted from a graphical terminal, it is
recommended to have a graphics display or an X terminal when the remote
maintenance option is chosen. A 2-node EPC400 configuration with 2 system
consoles is inadvisable.
