5.4 Preventive Maintenance
Use the following guidelines for general preventive maintenance:
• Keep the inside of the equipment items clean, especially if your facility
is subject to dust or dirt in the atmosphere. Use compressed air, an
antistatic cloth, or a gentle vacuum to clean the frame and internal
components.
• Observe proper procedures for preventing electrostatic discharge
when cleaning the units, and when inserting and removing cards.
Ensure that all tools and personnel handling individual components are
properly grounded.
• Avoid covering the front grille for any extended period. Blocking the
front grille will block the air flow through the fan and may overheat the
internal circuit cards.
