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 ÉQUIVALENT
RECOMMANDÉ PAR LE CONSTRUCTEUR. METTRE AU REBUT LES BATTERIES USAGÉES CONFOR-
MÉMENT AUX INSTRUCTIONS DU FABRICANT.
The motherboard battery maintains clock and CMOS settings when the node is without power for any reason. Con-
tact Avere Global Services if you suspect that the motherboard battery needs to be replaced.
2.7 Laser Radiation
CLASS 1 LASER PRODUCT
FXT Series nodes that contain optical networking ports may emit invisible laser radiation from those ports. When
no fiber-optic cable is connected, do not stare into the open apertures. In addition, install protective covers over any
optical ports that will not have a cable connected.
2.8 Thermal Considerations
• FXT Series nodes use front-to-back cooling airflow. If the FXT Series node is installed in a rack, the installer
is responsible for ensuring that adequate airflow is available through the rack to effectively cool the node.
• Environmental ambient temperature requirements apply to the area immediately around the node. For a node
installed into an enclosed rack or a rack with perforated doors, the ambient temperature requirement applies to
the area inside the rack or door, immediately around the node.
• Operating the FXT Series node in a rack with open EIA U spaces can cause unintended airflow paths and as-
sociated temperature inconsistencies. To maintain proper airflow and temperatures, cover all open rack spaces
with blank panels.
• Ensure that the node cover is in place when the node is operating to assure proper airflow and cooling. Ther-
mal damage to the system can occur if this practice is not strictly followed.
• Do not remove disk drives or power supply units unless a replacement component is immediately available.
If you remove a replaceable component, replace it before putting the unit back into service to ensure proper
airflow and cooling. Damage to the system can occur if this practice is not strictly followed.
2.9 Electrostatic Discharge (ESD) Precautions
An ESD event occurs when two objects with different electrical charges come into contact with each other. Elec-
tronic devices can be severely damaged by ESD.
When handling electronic modules such as disk drives, printed circuit boards (PCBs), and power supplies, observe
the following basic ESD precautions to prevent damage.
