Chapter 1 Preparing to Service the System 7
Note – If you have just installed an internal or external storage device other than a
Fibre Channel-Arbitrated Loop (FC-AL) drive or a Universal Serial Bus (USB)
device, or any new part that plugs in to the main logic board, bring up the system
after performing a reconfiguration boot (
boot -r).
The operating system cannot recognize newly added devices or parts until you have
performed a reconfiguration boot. The new boot will add any new devices to the
factory-configured device tree. For more information, see “How to Initiate a
Reconfiguration Boot” on page 12.
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. For
more information, see “How to Power Off the System” on page 5.
Caution – Before you power on the system, make sure that the top cover and front
doors are properly installed. See “How to Replace the System Cover” on page 33 for
more information.
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 local graphics console or ASCII terminal.
A local graphics console or ASCII terminal is required for viewing system messages.
For setup instructions, see “How to Attach an Alphanumeric Terminal” on page 38
or “How to Configure a Local Graphics Console” on page 39.
3. Turn the front panel keyswitch to the Power-On/Off position.
See “Keyswitch Settings” on page 3 for information about each keyswitch setting.
