5-4 Installing Options
Always hold a chip or board by its edges. Avoid touching
the components on the chip or board.
Take care when connecting or disconnecting cables. A
damaged cable can cause a short in the electrical circuit.
When installing a cable, route the cable so it is not pinched
by other components and is out of the path of the system
unit covers.
Prevent damage to the connectors by aligning connector
pins before you connect the cable.
Misaligned connector pins can cause damage to system
components at power-on.
When disconnecting a cable, always pull on the cable
connector or strain-relief loop, not on the cable itself.
