Safety Considerations
To avoid bodily harm and damage to electronic components, read the following safety and
comfort guidelines before unpacking and configuring the system components.
1 Avoiding Electrical Shocks
To avoid electrical shock, do not open the power supplies. There are no user-serviceable parts
inside. To avoid electrical shock and harm to your eyes by laser light, do not open the DVD laser
module. The laser module should be serviced by service personnel only. Do not attempt to make
any adjustment to the laser unit. See the label on the DVD for power requirements and wavelength.
This product is a Class 1 laser product.
2 Moving and Stabilizing Racks
To reduce the risk of personal injury or damage to equipment in the racks, do not attempt to
move the racks without adequate assistance, due to their height and weight. Also, do not attempt
to move a rack on an incline that is greater than 10 degrees from the horizontal.
When stabilizing racks, always ensure that the leveling jacks are extended to the floor and that
the full weight of each rack rests on the leveling jacks. For a multiple-rack installation, ensure
that the racks are coupled together.
3 Removing and Replacing Components
To reduce the risk of personal injury or damage to equipment in the racks, do not attempt to
extend more than one component from a rack at a time. The rack might become unstable and tip
over if more than one component is extended.
Be careful when pressing component rail release latches and sliding a component into the rack.
The slide rails can pinch your fingertips.
If you need to remove more than one component from a rack for any reason, always start from
the top of the rack and remove the lightest items first. When reloading the rack, start from the
bottom of the rack and replace the heaviest items first.
4 Removing and Replacing Component Covers
For your safety, never remove the cover from a component without first disconnecting the power
cord from the power outlet and removing any connection to a telecommunications network. If
a Power Protection Device is fitted to your system, you must shut down the computer using its
on/off switch, then remove the power cord before removing the components cover. Remove the
Power Protection Device cables before any servicing operation. Always replace the cover before
switching the component on again.
5 Using Cellular Phones and Other Wireless Technology
Cellular telephones and other wireless technology can interfere with the operation of components
in a HP SFS when the racks are opened and components are removed for service. You should
shut off all wireless technology when servicing the equipment.
6 Battery Safety Information
There is a danger of explosion if a battery is incorrectly installed. For your safety, never attempt
to recharge, disassemble, or burn an old battery. Replace the battery with the same or equivalent
type, as recommended by the manufacturer. The battery in this system is a lithium battery that
does not contain any heavy metals. However, to protect the environment, do not dispose of
batteries in household waste. Return used batteries either to the shop from which you bought
