Replacement or system upgrades 1.1
NOTE Do use orginal Siemens spare parts only! It’s not permitted
to use other parts!
Because the device has to be shut down before system
hardware components can be installed or uninstalled, it is a
good idea to print out the relevant sections of this chapter.
It may be necessary to update the BIOS when carrying out a
system expansion or hardware upgrade. A BIOS CD is avail-
able for each product (see (BIOS Installation / p. 7)).
The device must be switched off when system expansions
are installed or removed, and must not be in energy-saving
mode.
Remove the power plug before opening the device.
If the complete PC tower is replaced, all HW options and
extensions installed in the defective tower have to be
swapped from there to the replacement tower.
This chapter provides detailed instructions on modifying your device hardware (e.g.
installing boards or drives).
Read the supplied documentation before installing any new drives or boards.
NOTE If it was needed to remove a cable inside the housing, route
and fasten them like it was before.
Information about boards 0
Take care with the locking mechanisms (catches and centering pins) when you are replac-
ing boards or components on boards.
To prevent damage to the board or the components and conductors on it, please take care
when you insert or remove boards. Make sure expansion boards are inserted straight.
Never use sharp objects (screwdrivers) for leverage.
EBoards with electrostatic sensitive devices (ESD) are identified by the label shown.
When you handle boards fitted with ESDs, you must, under all circumstances, observe the
following points:
•You must always discharge static build up (e.g. by touching a grounded object) before
working.
•The equipment and tools you use must be free of static charges.
•Always hold boards with ESDs by their edges.
•Never touch pins or conductors on boards fitted with ESDs.
