DANGER Overloading a branch circuit is potentially a fire hazard and a shock hazard under certain conditions. To avoid these hazards, ensure that your system electrical requirements do not exceed branch circuit protection requirements. Refer to the information that is provided with your device for electrical specifications. After you plug one end of each server power cord into the power-supply outlets on the rear of the server and the other end of each power cord into an electrical outlet, the server can start in any of the following ways: v You can press the power-control button on the front of the server to start the server. Notes: 1. You can install a circular disk over the power-control button to prevent accidental manual power-off. This disk, known as the power-control button shield, comes with your server. 2. After you plug the power cords of your server into the electrical outlets, wait approximately 20 seconds before pressing the power-control button. During this time, the ISMP is initializing; therefore, the power-control button does not respond. v If the server is turned on and a power failure occurs, the server will start automatically when power is restored. v If ac power is present, the server is in Standby mode, and the server is connected to an Advanced System Management (ASM) interconnect network that contains at least one system with an optional Remote Supervisor Adapter installed, the server can be turned on from the Remote Supervisor Adapter user interface. v If ac power is present, the server is in Standby mode, and an optional Remote Supervisor Adapter is installed in the server, the server can be turned on from the Remote Supervisor Adapter user interface. v When you plug in your server for the first time, the Wake on LAN feature can turn on the server. v If your server was previously turned on, it must be properly placed in Standby mode for the Wake on LAN feature to turn on the server. v If your operating system supports the Preboot eXecution Environment (PXE) option and the PXE option is enabled through the Planar Ethernet PXE/DHCP menu choice under Start Options on the Configuration/Setup Utility program menu (see "Using the Configuration/Setup Utility program" on page 11), the integrated Gigabit Ethernet controller (see "Configuring the Gigabit Ethernet controller" on page 24) can turn on the server. Complete the following steps to manually turn on the server: 1. Review the information in "Before you begin" on page 41, "Handling static-sensitive devices" on page 42, and "Safety information" on page 169. 2. Turn on all external devices, such as the monitor. 3. Plug the server power cords into the power source. 4. Press the power-control button on the front of the server. Note: While the server is turning on, the power-on LED on the front of the server is lit. Chapter 1. General information 7

DANGER
Overloading a branch circuit is potentially a fire hazard and a shock hazard
under certain conditions. To avoid these hazards, ensure that your system
electrical requirements do not exceed branch circuit protection
requirements. Refer to the information that is provided with your device for
electrical specifications.
After you plug one end of each server power cord into the power-supply outlets on
the rear of the server and the other end of each power cord into an electrical outlet,
the server can start in any of the following ways:
v
You can press the power-control button on the front of the server to start the
server.
Notes:
1.
You can install a circular disk over the power-control button to prevent
accidental manual power-off. This disk, known as the power-control button
shield, comes with your server.
2.
After you plug the power cords of your server into the electrical outlets, wait
approximately 20 seconds before pressing the power-control button. During
this time, the ISMP is initializing; therefore, the power-control button does not
respond.
v
If the server is turned on and a power failure occurs, the server will start
automatically when power is restored.
v
If ac power is present, the server is in Standby mode, and the server is
connected to an Advanced System Management (ASM) interconnect network that
contains at least one system with an optional Remote Supervisor Adapter
installed, the server can be turned on from the Remote Supervisor Adapter user
interface.
v
If ac power is present, the server is in Standby mode, and an optional Remote
Supervisor Adapter is installed in the server, the server can be turned on from
the Remote Supervisor Adapter user interface.
v
When you plug in your server for the first time, the Wake on LAN feature can
turn on the server.
v
If your server was previously turned on, it must be properly placed in Standby
mode for the Wake on LAN feature to turn on the server.
v
If your operating system supports the Preboot eXecution Environment (PXE)
option and the PXE option is enabled through the
Planar Ethernet PXE/DHCP
menu choice under
Start Options
on the Configuration/Setup Utility program
menu (see “Using the Configuration/Setup Utility program” on page 11), the
integrated Gigabit Ethernet controller (see “Configuring the Gigabit Ethernet
controller” on page 24) can turn on the server.
Complete the following steps to manually turn on the server:
1.
Review the information in “Before you begin” on page 41, “Handling
static-sensitive devices” on page 42, and “Safety information” on page 169.
2.
Turn on all external devices, such as the monitor.
3.
Plug the server power cords into the power source.
4.
Press the power-control button on the front of the server.
Note:
While the server is turning on, the power-on LED on the front of the
server is lit.
