Connection hardware requirements
Before you can use the ICSRT to configure remote systems, you must install a RAD (MICS), or
use a software key to activate the Internal-RAD (CICS) on the systems that you want to manage.
The RAD Installation Guide provides details about the RAD module and how to physically
connect it to the Norstar system and to the remote computer. The CICS Programming and
Installation Guide explains how to configure an I-RAD.
Explaining RAD connections
There are three ways to connect to a RAD from your computer.
If you are managing a number of systems, you could have more than one type of connection. For
instance, if your computer is co-located with a system, you could use a serial cable in a
direct
connection. If another system is located in another building or too far away for a serial cable, you
might set up a
remote connection. You also might be managing another system that has high
security requirements, so that you need to be verified by a central operator before you connect, so
you would need to set up an operator-assisted connection to that system.
The three connection methods are:
• remote : through a dial-up modem and auto-answer line on Norstar system ( Figure 1 )
• operator or auto attendant-assisted : through a dial-up modem that calls a system operator or
auto attendant ( Figure 2 )
• direct : through a serial cable directly to the RAD ( Figure 3 )
Note:
Operator-assisted connections do not support the scheduled backup and restore
operations.
