only. The new fuse must be the same or equivalent as the one replaced. Contact technical support for details and support.
2-2 General Safety Precautions
Follow these rules to ensure general safety:
•Keep the area around the SuperBlade 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.
2-3 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.
