MAINTENANCE
The only regular maintenance required is to ensure that the cooling airflow remains unrestricted. To do this, it
may be necessary to clean the inside of the chassis at regular intervals to prevent dust build up inside the unit.
Generally the enclosure design and the wiring layout will ensure that the cooling is stable. However, bear in
mind that any modifications to the installation may cause a restriction of the air vents.
After a period of several years, it may be necessary to replace the battery on the processor board, if it cannot
maintain the CMOS memory whilst the AC power is disconnected.
Replacing the Processor Battery
The processor board includes a small 3V-lithium battery (type CR-2032) to retain the BIOS settings in the
CMOS memory when the unit is powered down. Before attempting to replace the battery, please read the
precautions detailed in the introductory section. Remember that even discharged batteries can present a real
personnel hazard if mistreated.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the
manufacturer.
Dispose of used batteries according to the manufacturer's instruction.
ATTENTION
Il y a danger d'explosion s'il y a remplacement incorrect de la batterie.
Remplacer uniquement avec une batterie du même type ou d'un type
recommandé par le constructeur.
Mettre au rébut les batteries usagées conformément aus instructions du
fabricant.
The battery is located on the motherboard adjacent to the AGP (brown) socket, underneath the hard disk
drive mounting plate
.
Remove the hard drive assembly as indicated in the section on Upgrading the CPU
:
The battery is mounted vertically in the holder held in place by the clip in the top.
Do NOT under any circumstances try to remove the battery with metallic tools (pliers, tweezers etc.).
They will short out the battery with possible disastrous results.
To remove the battery, push the top of the retaining clip away from the AGP connector to force it away from
the battery, then lift the battery clear of the holder.
Replace the battery by one of the same type, ensuring that it is fitted with the positive terminal facing the
CPU, and that the clip is fully engaged. When the battery has been replaced, the BIOS settings will revert to
their default settings. Reset them as necessary to suit your application.
Fuses
There are no user-serviceable or replaceable fuses within the unit.
