Installing a circuit card

During repair and maintenance procedures do the following:
• Turn off the circuit breaker or switch for a module power supply before
the power supply is removed or inserted.
• In AC-powered systems, capacitors in the power supply must discharge.
Wait five full minutes between turning off the circuit breaker and
removing the power supply from the module.
• Software disable cards, if applicable, before they are removed or
inserted.
• Hardware disable cards, whenever there is an enable/disable switch,
before they are removed or inserted.
• Return defective or heavily contaminated cards to a repair center. Do not
try to repair or clean them.
This procedure provides detailed installation instructions for Meridian 1
