Safety instructions
NOTE:
Whenever you need to lift the system, get others to assist you. To avoid injury, do not attempt to lift the system by
yourself.
CAUTION:
Ensure that two or more people lift the system horizontally from the box and place it on a flat
surface, rack lift, or into the rails.
WARNING:
Opening or removing the system cover while the system is powered on may expose you to a risk of
electric shock.
WARNING:
Do not operate the system without the cover for a duration exceeding five minutes. Operating the
system without the system cover can result in component damage.
CAUTION:
Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or
telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by
your warranty. Read and follow the safety instructions that are shipped with your product.
NOTE:
It is recommended that you always use an antistatic mat and antistatic strap while working on components inside
the system.
CAUTION:
To ensure proper operation and cooling, all system bays and fans must always be populated with a
component or a blank.
NOTE:
While replacing the hot swappable PSU, after next server boot; the new PSU automatically updates to the same
firmware and configuration of the replaced one. For updating to the latest firmware and changing the configuration, see the
Lifecycle Controller User's Guide at https://www.dell.com/idracmanuals.
NOTE:
While replacing faulty storage controller, FC, or NIC card with the same type of card, after you power on the
system; the new card automatically updates to the same firmware and configuration of the faulty one. For updating to
the latest firmware and changing the configuration, see the Lifecycle Controller User's Guide at
idracmanuals.
