• 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, close the system back up and secure it to the rack
unit with the retention screws after ensuring that all connections have been made.
Caution: The C2112-4KL1 system and any other rackmounted equipment is not to be used as a
shelf or workspace.
Figure 2-2 Slide-rail Mounted Equipment Caution
Caution: 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. The discharge 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.
