Chapter 5. Remote Support Facility Installation Planning
This section describes the telephone line and modem requirements for the
Hardware Management Console Remote Support Facility (RSF). The Remote
Support Facility provides communication to a centralized IBM support network for
problem reporting and service, as well as providing a means for remote operation of
the Hardware Management Console.
It is the customer's responsibility to arrange for installation and all costs of
common-carrier equipment.
