via the TERM interface, or by performing a successful telnet login via the Ethernet port FCC1
(FE). If the operator does not intervene, the boot operation is continued after the boot wait time
has been exceeded.
5.2.1 MC1 (Abort) Signal
The MC1 (Abort) signal is routed to the VMP3 from the carrier board via the System Interface
(CON1 connector) and, if made available from the carrier, provides the operator with the ability
to directly terminate the boot operation during the boot wait time which is indicated by the al-
ternately asserted MC6 (LED1) signal. This is the sole purpose of the MC1 (Abort) signal during
the NetBootLoader operation.
5.2.2 TERM Serial Interface
The TERM serial port, if realized on the carrier board, is used to provide direct operator inter-
facing to the NetBootLoader. As soon as the CPU board has been initialized this port is acti-
vated and the operator may input commands. During the boot wait time the operator may
terminate the boot operation and take control of the NetBootLoader. Once the boot wait time is
exceeded the command interpreter is normally deactivated and the boot process is continued.
If the NetBootLoader does not find a valid boot image, the boot process is discontinued and
system control is returned to the operator via the NetBootLoader.
The TERM serial interface may either be directly connected to a terminal device or may inter-
face with a terminal emulator.
5.2.3 SER0 Serial Interface
The SER0 serial port is used to provide the NetBootLoader with the ability to access Motorola
S-Records for programming an application to FLASH. No command interpreter is available for
this interface.
5.2.4 Ethernet Port FCC1 (FE) Interface
The Ethernet port FCC1 (FE) provides the capability of remotely interfacing with the NetBoot-
Loader. Prior to using this interface it is necessary to configure the Ethernet port settings. This
is accomplished via the TERM interface or a dhcp/bootp server. Once the port settings have
been configured, the remote operator has the same capabilities as with the TERM interface.
During the boot wait time the operator gains control of the NetBootLoader by performing a tel-
net login it via the Ethernet port FCC1 (FE). This causes the boot operation to be terminated
and gives control to the remote operator.
In addition to the operator interface via this interface, the NetBootLoader can also use it for tftp
and ftp server accessing.
