Note – If JumpStart automatic installation begins unintentionally, interrupt it
by pressing “L1-A” (Stop-A) or “Break” (on ttya). Perform a manual
installation when you are ready.
If JumpStart completes the installation incorrectly, you may need to reinstall
Solaris 2.x manually.
3.2 Powering On the System
Note –
It is advisable to connect an ASCII terminal to the system during
installation. See Section 2.5, “Connecting an ASCII Terminal,” for terminal
settings and connections.
Observe the yellow (middle) LED on the front panel. It should go off when
boot completes. If it remains lit, observe the terminal screen for boot messages
produced by the firmware diagnostic program during power on.
To power on the Enterprise 3000 system:
1. Begin with a safety inspection of the system.
a. Use the handle on the front of the system to pull the front door open.
b. Turn the system key switch to (the Standby position).
See Figure 3-1.
c. Turn the AC power sequencer power switch to Off.
The AC power sequencer is at the rear of the enclosure. See Figure 3-2.
d. Verify that the AC power cord is plugged into a wall socket.
Caution – Do not disconnect the power cord from the wall socket when
working on the server. This connection provides a ground path that prevents
damage from uncontrolled electrostatic discharge.
2. Turn on power to any expansion cabinets.
Read the documentation supplied with each type of expansion cabinet for
specific instructions.
3. Turn on the terminal (if applicable).
