1.5 Powering Up
The initial power up can easily be done by connecting a terminal to ttya (serial port A). The
advantage of using a terminal is that no frame buffer, monitor, or keyboard is used for initial
power up, which facilitates a simple start up.
Please see the chapter “Boot the System” on page 12 for more detailed information on booting
the system.
1.5.1 VME Slot-1 Device
The SPARC CPU-5CE can be plugged into any VMEbus slot; however, the default
configuration sets the board as a VME slot-1 device, which functions as VME system
controller. To configure your CPU-5CE so it is not a VME slot-1 device, the default
configuration must be changed so that SW5-1 is OFF.
CAUTION
Before installing the SPARC CPU-5CE in a miniforce chassis, please first disable the
VMEbus System Controller function by setting switch SW5-1 to OFF.
1.5.2 VMEbus SYSRESET Switches
When the SPARC CPU-5CE is a VMEbus slot-1 device, it generates the SYSRESET signal
to the VMEbus. This can be disabled by setting the switch SW9-1 to OFF.
An external SYSRESET generates an on-board RESET in the default switch setting, i.e.,
SW9-2 is ON. When SW9-2 is OFF, the external SYSRESET does not generate an on-board
RESET.
1.5.3 Serial Ports
By default, both serial ports are configured as RS-232 interfaces. It is also possible to
configure both ports as RS-422 or RS-485 interfaces. This optional configuration is achieved
with the special FORCE Hybrids FH-003 and FH-005.
The chapter “Default Switch Settings” on page 5 shows the necessary switch settings for
RS-232 operation, where SW3 controls serial port A and SW4 controls serial port B. Please
check that the switches are set accordingly.
