ROUTINE MAINTENANCE5-15Edition OneXC1000 Service5.8 STORING AND HANDLING DISK DRIVESHard-disk drives can be damaged if improperly stored or handled. Shockor vibration, electrostatic discharge (ESD), and effects from humidity candamage the disk drive.Dropping a drive from a height of as little as 1/ 2 inch ontoa solid surface can shock a drive. This results in damageto the drive.Caution!Use the following guidelines to ensure safe and proper handling of diskdrives:Shock or vibration: Subjecting a hard-disk drive to excessive shock orvibration that causes the causes the drive head to contact the mediasurface results in permanent damage to the drive.Electrostatic discharge: Exposing the electronic components of a harddisk to ESD results in damage to the components. When handling drives,use the following precautions: Before removing a drive from a XC1000, either attach an antistaticwrist strap or use an equivalent method, to provide a high-resistancepath to ground. After a drive is removed, immediately place it in an antistatic bag. When installing a drive, keep the drive in its antistatic bag until readyfor use. When returning a drive to Octel Communications, place the drive inan antistatic bag, and place the bag into a shipping containerimmediately.Humidity: If moisture forms on the media surface of the drive, it causesthe head to stick to the media, resulting in damage to the media surface.Use the following precautions when working in an environment with highhumidity: Keep the disk drive in a sealed bag to prevent moisture from condens-ing on it. Do not store disk drives in a high-humidity environment for long periodsof time, because, over time, moisture will penetrate a sealed bag.SECTION 5.8
