incorrect

responses

are

given

to

the

password

prompt,

the

server

locks

up

and

must be turned

off

 

and

turned on

again

to

be

reset. If

the

 

power-on

password

has

been

lost,

then

the

power-on password jumper

must

be

reset

or

disabled:

 

 

Ÿ

To reset the power-on

password,

remove

the

server

power cable;

then

remove

 

 

 

the

server

battery

for 30 seconds. See

“Changing the

page 4-36

for

 

the

location

of

the

battery.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

ŸTo disable the power-on password, see “Enabling and Disabling the Power-On Password” on page 4-8.

Attention : Removing the battery may also erase system configuration information stored in the nonvolatile random access memory (NVRAM), such as the custom boot list.
