Rack stability
Rack stability protects personnel and equipment.
WARNING!
To reduce the risk of personal injury or damage to equipment:
• Ex tend leveling jacks to the floor.
• Ensure that the full weight of the rack rests on the leveling jacks.
• Install stabilizing feet on the rack.
• In multiple-rack installations, fasten racks together se curely.
• Extend only one rack component at a time. Racks can become unstable if more than one component
is extended.
Taking ESD precautions
Components within the library contain static-sensitive parts. To prevent damage to these parts while
performing installation, m aintenance, or replacement procedures, observe the following electrostatic
discharge (ESD) precautions:
• Always use the Ethernet cables that come with your product.
• Keep the rack turned off during all installation, maintenance, and replacement procedures,
unless specifically instructed to do otherwise.
• Use an antistatic wrist strap when touching internal rack components. To use the wrist strap
properly, place the ba nd around your wrist and attach the clip to the rack frame. Keep the strap
on until you are ready to close the rack doors.
• Keep static-sensitive parts in their shipping containers until ready for installation.
• Do not place static-sensitive parts on any metal surface. If you need to put down a static-sensitive
part, place it inside its protective shipping bag or on a grounded antistatic mat.
• Avoid direct contact with static-sensitive parts. Avoid touching connectors a nd discrete
components.
• Closerackdoorswhennotworkingontherack.
• Be careful when installing the rack or handling components in dry climates or environments where
cold weather heating is used. Environm ents such as these with lower relative humidity have
greater potential to produce static electricity.
