load or unload a rack. A third person might be required to help align the server if the server is
installed higher than check level.
•
For rack stability, make sure only one unit is extended at a time. A rack might get unstable if
more than one server unit is extended.
•
Make sure the rack is stable when you operate a server in the rack.
•
To maintain correct airflow and avoid thermal damage to the server, use blank panels to fill
empty rack units.
ESD prevention
Electrostatic charges that build up on people and tools might damage or shorten the lifespan of the
system board and electrostatic-sensitive components.
Preventing electrostatic discharge
To prevent electrostatic damage, follow these guidelines:
•
Transport or store the server with the components in antistatic bags.
•
Keep the electrostatic-sensitive components in separate antistatic bags until they arrive at an
ESD-protected area.
•
Place the components on a grounded surface before removing them from their antistatic bags.
•
Avoid touching pins, leads, or circuitry.
Grounding methods to prevent electrostatic discharge
The following are grounding methods that you can use to prevent electrostatic discharge:
•
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
•
Take adequate personal grounding measures, including wearing antistatic clothing and static
dissipative shoes.
•
Use conductive field service tools.
•
Use a portable field service kit with a folding static-dissipating work mat.
Cooling performance
Poor cooling performance might result from improper airflow and poor ventilation and might cause
damage to the server.
To ensure good ventilation and proper airflow, follow these guidelines:
•
Install blanks if the following module slots are empty:
Drive bays.
Fan bays.
PCIe slots.
Power supply slots.
•
Do not block the ventilation openings in the server chassis.
•
To avoid thermal damage to the server, do not operate the server for long periods in any of the
following conditions:
Access panel open or uninstalled.
Air baffles uninstalled.
PCIe slots, drive bays, fan bays, or power supply slots empty.
