General Safety Precautions
Follow these rules to ensure general safety:
•
Keep the area around the server clean and free of clutter.
•
Place the blade module cover and any system components that have been removed
away from the system or on a table so that they won't accidentally be stepped on.
•
While working on the system, do not wear loose clothing such as neckties and
unbuttoned shirt sleeves, which can come into contact with electrical circuits or be
pulled into a cooling fan.
•
Remove any jewelry or metal objects from your body, which are excellent metal
conductors that can create short circuits and harm you if they come into contact with
printed circuit boards or areas where power is present.
•
After accessing the inside of the system, replace the blade module's cover before
installing it back into the blade enclosure.

Electrostatic Discharge Precautions
Electrostatic discharge (ESD) is generated by two objects with different electrical
charges coming into contact with each other. An electrical discharge is created to
neutralize this difference, which can damage electronic components and printed circuit
boards.
The following measures are generally sufficient to neutralize this difference
before
contact is made to protect your equipment from ESD:
•
Use a grounded wrist strap designed to prevent static discharge.
•
Keep all components and printed circuit boards (PCBs) in their antistatic bags until
ready for use.
•
Touch a grounded metal object before removing the board from the antistatic bag.
•
Do not let components or PCBs come into contact with your clothing, which may
retain a charge even if you are wearing a wrist strap.
•
Handle a board by its edges only; do not touch its components, peripheral chips,
memory modules or contacts.
•
When handling chips or modules, avoid touching their pins.
•
Put the mainboard and peripherals back into their antistatic bags when not in use.
•
For grounding purposes, make sure the blade enclosure provides excellent
conductivity between the power supplies, the blade modules and the mainboard.

Operating Precautions
Care must be taken to assure that the cover of the blade unit is in place when the blade
is operating to assure proper cooling. Out of warranty damage to the blade can occur if
this practice is not strictly followed.
Any drive carrier without a hard drive installed must remain fully installed in the drive bay
when the blade module is operating to ensure proper airflow.
