connector pins. When connecting cables, ensure that the connectors and ports
are correctly oriented and aligned.
CAUTION: To disconnect a network cable, first unplug the cable from your
computer and then unplug the cable from the network device.
CAUTION: Press and eject any installed card from the media-card reader.
