What To Do - Sun Microsystems Enterprise 250 Owner's Manual

Note -
Do not use this power-on procedure if you have just installed an internal or
external storage device, or any new part that plugs into the main logic board. To
power on the system after adding any of these options, see "How to Initiate a
Reconfiguration Boot" on page 58.

What to Do

Caution - Never move the system when system power is on. Movement can cause
catastrophic disk drive failure. Always power off the system before moving it.
Caution - Before you power on the system, make sure that the side access panel and
all plastic outer panels and doors are properly installed.
Caution - Removing the side access panel or removable media assembly activates
the system power interlock switches. This safety mechanism prevents all DC voltages
(except 5V standby power) from reaching any internal component when the side
panel or removable media assembly is removed and the front panel keyswitch is in
the Power-on position.
1. Turn on power to any peripherals and external storage devices.
Read the documentation supplied with the device for specific instructions.
2. Turn on power to the monitor or terminal.
A terminal or monitor is required for viewing system messages. For setup
instructions, see "How to Attach an Alphanumeric Terminal" on page 50 or
"How to Configure a Local Graphics Console" on page 51.
3. Turn the front panel keyswitch to the Power-on, Diagnostics, or Locked
position.
See "About the Status and Control Panel" on page 6 for information about each
keyswitch setting.
