Configuring a Remote Support Modem

8. Press the keyboard’s left arrow or Esc two times to return to the main
menu of the Diagnostic Partition or Platform CD-ROM. Select “Reboot
System” from this menu.
Since both console redirection and the modem utilities interface with the
COM port, you must reboot your server to re-initialize console redirection
fully.
In some instances, redirection may not be operational when you finish
configuring the modem. Rebooting your server corrects this problem.
Using a Remote Password
When you run the modem utilities from the Diagnostic Partition or Platform
CD-ROM, they initialize the COM port and modem. The utilities transmit
modem command strings through the COM port.
Using the COM port and transmitting commands to the modem disrupts
console redirection functions provided by the system BIOS. A person who is
accessing the server remotely relies on console redirection to view the server
screen and input keyboard data. If redirection is disrupted by the modem
utilities, there is no remote indication of what is happening on the server
screen or what to enter at the keyboard. For these reasons, you cannot run
most of the modem utilities remotely.
For security reasons, two modem applications on the Diagnostic Partition and
Platform CD-ROM are written especially for remote use. These applications
set or delete a Remote Password.
It is important to be able to set and delete the Remote Password from a remote
location. This allows remote management of a server in a “lights out”
environment, if the server console and keyboard hardware are not easily
accessible, or if local personnel are not sufficiently trained.
In these situations, call-back passwords are required to be defined for the
server’s modem, for security reasons. Console redirection should be enabled
by default and the modem set for auto-answer with one or more call-back
passwords defined.
