network manager.
The following section explains how to use the three
positions on the key mode switch:
Warning: The Reset button is enabled when the key
mode switch is in the Normal or Service position. If
you press Reset, data can be damaged or lost if the
Model 170 is still running.
• The Normal position is used for unattended
operation. The IPL proceeds according to the
list of adapters established during the
configuration of the Model 170.
• The Service position is used for attended
operation when hardware or software service
is performed. The Service position allows
debug and dump procedures. In the Service
position, the Model 170 attempts to IPL from the
diskette drive, if it contains a diskette, or from
the disk.
• The Secure position is used to prevent user
intervention locally from the operator panel
and remotely from the SNMP network manager.
