Safety considerations
Always follow safety recommendations to avoid damage to the system or harm to personnel.
CAUTION:
● If the system is used in a manner not specified by the manufacturer, the protection provided by the
equipment could be impaired.
● The RJ45 ports on the motherboard, PCI cards, or I/O modules are for Ethernet connection only and must
not be connected to a telecommunications network.
CAUTION: Improper installation on the rails may damage the rails or cause the system to fall when extended.
When extending the system from the rack, pull outward slowly and verify the system is properly installed on the
rails.
Review and follow these important safety recommendations:
● For ESD protection, Dell recommends that you wear a suitable antistatic wrist or ankle strap. Observe all conventional ESD
precautions when handling plug-in modules and components.
● All plug-in modules and blank plates are part of the fire enclosure system and should not be removed unless a replacement
can be added immediately. Do not run the system without all parts in place.
● Provide a suitable power source with electrical overload protection.
● Provide a safe electrical ground connection to each power cord. Check the grounding of the power sources before applying
power.
● DD9410 and DD9910 systems must be operated only from a power supply input voltage range of 100–240 VAC and 50–60
Hz
● DS600 shelves use 200-240 VAC and 50-60 Hz.
● FS240 shelves use 90-264 VAC and 47-63 Hz.
● The system is intended to operate with all installed power supplies working as designed.
● A faulty power supply module should be replaced within 24 hours.
● Always disconnect the power connections before removing or replacing a power supply module.
● The main way to disconnect power from the system is to unplug the power supply cord.
● The system includes two power supplies. To completely remove system power, you must disconnect both power supplies.
● Always disconnect the power connections before moving the system.
● If you think the unit is damaged in any way, permanently unplug it.

CAUTION:
The system components are heavy. To avoid personal injury and/or damage to the equipment,
do not attempt to install or remove system components without a mechanical lift and/or help from another
person.
○ DD9410 and DD9910 systems weigh up to 79.58 lbs (36.1 kg).
○ DS600 shelves weigh up to 222 lbs (100.69 kg).
○ FS240 shelves weigh up to 47.99 lbs (21.76 kg).
Working with a portable lift
If you are installing the shelf with all field replaceable units (FRUs) removed, you can install the shelf without using a lift. If you
need to install the shelf with FRUs onboard, use a portable lift.
Service personnel generally use the portable lift manufactured by Alum-A-Lift. Instructions for this lift are included in the lift kit.
NOTE:
If you are using a portable lift other than the Alum-A-Lift, adapt these instructions as necessary while following all
required safety requirements.
Lift requirements
For installations in racks that are 28U (49 inches) or less above the floor, use the lower mast, which is rated for 400 pounds.
For installations in racks that are more than 28U (49 inches) above the floor, use the lower mast configuration and a support
table with the "Voyager" conversion kit, which is rated for 225 pounds.
