Circuit cards
553-3001-520 Standard 17.00 January 2002
Handle cards as follows:
• Unpack or handle cards away from electric motors, transformers, or
similar machinery.
• Handle cards by the edges only. Do not touch the contacts or
components.
• Set cards on a protective antistatic bag. If an antistatic bag is not
available, hand-hold the card, or set it in a card cage unseated from the
connectors.
• Store cards in protective packing. Do not stack cards on top of each other
unless they are packaged.
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. Figure 1 on page 16 shows the recommended connection
points for the wrist strap and the bare metal strips you should touch.
