System upgrades
i
As the device has to be shut down in order to install/deinstall system hardware
components, 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. Additional information is contained in the "BIOS Setup" manual or
possibly in the technical manual for the mainboard.
When installing components that become very hot, make sure that the maximum
permissible temperature is not exceeded.
The devices are very similar to each other. Therefore, only the Celsius V is shown in the
following illustrations. In case of differences, this will be pointed out at the appropriate
point.
!
The device must be switched off when installing/removing the system expansions and may
not be in the energy-saving mode.
Remove the power plug before opening the device.
This chapter describes all the activities required to modify your device hardware (e.g. installing
boards or drives).
Read the supplied documentation before installing new drives and/or boards.
Refer to the technical manual for the mainboard before making any extensions to the mainboard.
Information about boards
Take care with the locking mechanisms (catches and centring pins) when you are replacing 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.
Boards with electrostatic sensitive devices (ESD) are identifiable 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.
