– Distribute the weight of the object equally between your feet.
– Use a slow lifting force. Never move suddenly or twist when you lift a heavy object.
– To avoid straining the muscles in your back, lift by standing or by pushing up with your leg muscles.
• Back up all important data before you make changes related to the disk drives.
• Have a small flat-blade screwdriver, a small Phillips screwdriver, a T8 screwdriver and a T20 torx
screwdriver available.
• To view the error LEDs on the system board (system board assembly) and internal components, leave the
power on.
• You do not have to turn off the server to remove or install hot-swap power supplies, hot swap fans, or hot-
plug USB devices. However, you must turn off the server before you perform any steps that involve
removing or installing adapter cables, and you must disconnect the power source from the server before
you perform any steps that involve removing or installing a riser card.
• When replacing power supply units or fans, make sure to refer to redundancy rules for these components.
• Blue on a component indicates touch points, where you can grip to remove a component from or install it
in the server, open or close a latch, and so on.
• Terra-cotta on a component or a terra-cotta label on or near a component indicates that the component
can be hot-swapped if the server and operating system support hot-swap capability, which means that
you can remove or install the component while the server is still running. (Terra-cotta can also indicate
touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap
component for any additional procedures that you might have to perform before you remove or install the
component.
• The Red strip on the drives, adjacent to the release latch, indicates that the drive can be hot-swapped if
the server and operating system support hot-swap capability. This means that you can remove or install
the drive while the server is still running.
Note: See the system specific instructions for removing or installing a hot-swap drive for any additional
procedures that you might need to perform before you remove or install the drive.
• After finishing working on the server, make sure you reinstall all safety shields, guards, labels, and ground
wires.
