5.1 Handling Electrostatic Discharge-Sensitive Parts
Take the following precautions when handling 7131 Storage Tower parts:
1. Attention: The drives, backplane, and SE/DIFF card can be damaged by electrostatic discharge (ESD). ESD-sensitive parts are
wrapped in antistatic bags to prevent damage. Handle the ESD-sensitive parts carefully to prevent permanent damage.
2. Do not remove the ESD-sensitive part from the antistatic bag (see Figure 5-1) until you are ready to install it.
Figure 5-1. Antistatic Bag
3. Do not place any ESD-sensitive parts on the machine cover or on a metal table. Large metal objects can become discharge paths if
they are not grounded. If you must set aside an ESD-sensitive part, first place it into an antistatic bag.
4. Be very careful when you work with ESD-sensitive parts in cold weather, as low humidity and heating increase static electricity.
5. When either end of a SCSI cable is unconnected to a device, the pins on the SCSI signal cable are exposed and must not be touched.
