5.3.2 Function of the keys and switches

UNIT EMERGENCY switch (SE700 / SE500 only)

The UNIT EMERGENCY switch switches the system off as quickly as possible when an emergency or disaster

occurs. The Server Unit is switched off immediately when the switch is pressed.

This switch should only be used in the utmost emergency. If there is still time, the system should be switched off

normally using the STAND-BY key.

CAUTION!

There is a risk of data loss. When the UNIT EMERGENCY switch is pressed, system data can no longer

be written back.

After it has been pressed, the UNIT EMERGENCY switch is mechanically locked. POWER ON can only

be used again to switch the system on when the lock has

been canceled by Customer Support.

CAUTION!

Danger of fire and electric shock

After the UNIT EMERGENCY has been pressed, some of the circuits remain live!

Only some of the circuits are switched off. Switch off the fuses in the power distribution cabinet to

eliminate this danger.

Procedure in the event of an emergency power-off:

Pull out and remove the protective cover of the UNIT EMERGENCY switch.

Move the switch down (from position to position ).

POWER ON key

This key initiates the sequential power-on of the power supplies of the entire /390 system (/390-CPU, AROMA, CHE

boxes). They are powered on independently of an automatic power-on/off function.

IMPL (Initial Micro Program Load) is then performed. The system is ready when POWER ON lights up and the

status indicator displays 000.

When POWER ON IPL is configured, the operating system is then loaded (see SVP frame LOAD PRESET1,

"Server Unit /390" Operating Manual [ ]).

Before pressing the POWER ON key, check whether the following requirements are met:

POWER ON is flashing and the status indicator displays nothing. When all displays are off and the status

indicator displays nothing, the power supply of the Server Unit is switched off. In this case switch the fuses in

the power distribution cabinet on to supply the Server Unit with power.

The status indicator displays no error code. If an error code is displayed, notify Customer Service of this error

code.

Press the POWER ON key to begin powering up the system. The power-up sequence begins. POWER ON lights up

and the status indicator displays a sequence from 001 through 399 while powering up.
