• Orange on a component or an orange label on or near a component indicates that the component can be
hot-swapped if the solution and operating system support hot-swap capability, which means that you can
remove or install the component while the solution is still running. (Orange 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 solution and operating system support hot-swap capability. This means that you can remove or install
the drive while the solution 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 solution, make sure you reinstall all safety shields, guards, labels, and
ground wires.
System reliability guidelines
Review the system reliability guidelines to ensure proper system cooling and reliability.
Make sure the following requirements are met:
• When the solution comes with redundant power, a power supply must be installed in each power-supply
bay.
• Adequate space around the solution must be spared to allow solution cooling system to work properly.
Leave approximately 50 mm (2.0 in.) of open space around the front and rear of the solution. Do not place
any object in front of the fans.
• For proper cooling and airflow, refit the solution cover before you turn the power on. Do not operate the
solution for more than 30 minutes with the solution cover removed, for it might damage solution
components.
• Cabling instructions that come with optional components must be followed.
• A removed hot-swap drive must be replaced within two minutes after removal.
• A removed hot-swap power supply must be replaced within two minutes after removal.
• All processor sockets must contain either a socket cover or a processor with heat sink.
• When more than one processor is installed, fan population rules for each solution must be strictly
followed.
Working inside the solution with the power on
Guidelines to work inside the solution with the power on.
Attention: The solution might stop and loss of data might occur when internal solution components are
exposed to static electricity. To avoid this potential problem, always use an electrostatic-discharge wrist
strap or other grounding systems when working inside the solution with the power on.
• Avoid loose-fitting clothing, particularly around your forearms. Button or roll up long sleeves before
working inside the solution.
• Prevent your necktie, scarf, badge rope, or long hair from dangling into the solution.
• Remove jewelry, such as bracelets, necklaces, rings, cuff links, and wrist watches.
• Remove items from your shirt pocket, such as pens and pencils, in case they fall into the solution as you
lean over it.
• Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the solution.
