Safety Inspection Checklist - Lenovo ThinkEdge SE350 V2 Hardware Maintenance Manual

• To view the error LEDs on the system board and internal components, leave the power on.
• You do not have to turn off the server to remove or install hot-plug USB devices. However, you must turn
off the server and disconnect the power source from the server before performing any steps that involve
removing or installing internal cables.
• 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 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 this
component can be removed or installed 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 removing or installing 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 the drive can be removed
or installed 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 removing or installing the drive.
• After finishing working on the server, make sure to reinstall all safety shields, guards, labels, and ground
wires.
