CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have connectors with locking
tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep
them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented
and aligned.
CAUTION: To avoid damaging the computer, perform the following steps before you begin working inside the computer.
CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device.
CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back
of the computer. While you work, periodically touch an unpainted metal surface to dissipate static electricity, which could harm internal
components.
