    Precautions 19 Precautions To avoid personal injury and equipment damage, review the following guidelines before handling Meridian 1 equipment. Power equipment There are no user-repairable components in the power system. If a power supply fails, the complete unit must be replaced. Do not disassemble a power supply under any circumstances.

  • Page 20: Circuit Cards

    To avoid card damage from static discharge, wear a properly connected antistatic wrist strap when you work on Meridian 1 equipment. If a wrist strap is not available, regularly touch one of the bare metal strips in a module to discharge static.
