SPARC/CPU-5TE
Installation Guide
1.4
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 startup.
Please see the chapter “Boot the System” on page 14 for more detailed information on booting
the system.
1.4.1
VME Slot-1 Device
The SPARC CPU-5TE can be plugged into any VMEbus slot; however, the default
configuration automatically detects that the board is a VME slot-1 device, which functions as
VME system controller. To configure your CPU-5TE so it is not a VME slot-1 device, the
default configuration must be changed so that SW10-2 is OFF.
CAUTION: Before installing the SPARC CPU-5TE in a miniforce chassis, please first disable
the VMEbus System Controller function by setting switch SW10-2 to OFF.
1.4.2
VMEbus SYSRESET
1.4.2.1
SYSRESET Input
A SYSRESET received from VMEbus generates an on-board RESET if switch SW11-1 is ON
(default setting). When SW11-1 is OFF, the SYSRESET received from the VMEbus does not
generate an on-board RESET.
1.4.2.2
SYSRESET Output
There are several possible ways for the CPU-5TE to generate a SYSRESET signal to the
VMEbus. One way is when the CPU-5TE is a VMEbus slot-1 device and an on-board local
SBus reset occurs, then the CPU-5TE generates the SYSRESET signal to the VMEbus. A
second way for the SYSRESET signal to be generated is by power-up reset. Power-up reset
occurs by switching on the power. Power-up Reset also occurs when the power monitor
detects power fail or the front panel reset key is toggled.
This SYSRESET signal can be disabled by setting the switch SW11-2 to OFF.
1.4.3
Serial Ports
By default, both serial ports are configured as RS-232 interfaces. The chapter “Default Switch
Settings” on page 4 shows the necessary switch settings for RS-232 operation.
