Internal USB system board 2x5 connector

The 2x5 internal USB system board connector can be mated to either a wide 2x5 option cable connector or a narrow 1x5 option cable connector.

CAUTION: Possible equipment damage.

Always key all option connectors to the blank pin 9 position to prevent damage to connectors and equipment. Always connect a narrow 1x5 option cable connector to pins 1,3,5, and 7 only.
