Turning On the System
To turn on the system, perform the following, with all peripheral devices
turned off:
1 Turn on the power to your display. The power indicator LED on the dis-
play unit shows that it is turned on, even if the screen remains dark. Make
sure of the following:
• For systems using a graphics display, there must be a keyboard con-
nected (the monitor will not initialize if no keyboard is present).
• The appropriate LAN connection has been made to the Model 744.
• If you use a remote graphical display host connected via LAN, make
sure the remote system is configured to host the board computer. Nor-
mally, you will use a character terminal connected to the RS-232C
(Port A) on the board computer.
2 Check the SCSI connections and power on any peripheral devices.
3 Turn on the VMEbus chassis. Your Model 744 system turns on with the
VMEbus chassis that it is plugged into.
NOTE: If your Model 744 does not have on-board or supplementary graphics, the
default console display is available through the RS-232C (Port A).
If there is a problem arising from the console path having been changed, you
can boot your Model 744 to display on any console device. See “Configuring
the Console Path and Display Format” and “Using the Emergency Interactive
Console Search” in Appendix A.
The green LED (on the right) on the panel blinks slowly until the OS is
booted; then remains on. The red LED (on the left) will be on when power
is activated and before HP-UX boots. After VME services is booted, the
red light is off.
