System Power-On Methods

This section discusses the following system power-on methods:

ŸPower-on Switch

ŸService Processor Menus

Privileged

users can power-on the system bySystemselecControling

the

Power

Menu

option

from

the main

menu

and then Powerselecting-on

the

System

option from

the

system

power

control menu. General users should select

Power-on

System

on

the

general

user

menu.

 

ŸRemote Power-on via Ring-Indicate Signal

The

server

automatically

powers on

when

it

detects

a

"ring

indicate" signal from

a

modem

attached

to

serial

port 1 (S1) or serial

port 2

(S2).

A remote

user

can

call

the

server

to

activate ring detection by the modem.

Listen

for

a

few

more

rings

than

the

threshold number

for

starting the system.

The

system

powers

on

without

answering

the

call.

The Service Processor can be enabled to recover from the loss of ac power (see

Enable/Disable Unattended Power-On Mode

in

the SYSTEM POWER

CONTROL

 

MENU). When ac power is restored,

the system returns to the then current

power state at the time ac loss

occurred. For example,

if the system

was

powered-on when ac loss occurred,

it

reboots/restarts when power is restored. If

the system was powered-off when

ac

loss

occurred, it

remains off when

power is

restored.
