NIC Hardware Key
iSCSI and other future functionalities for the system’s embedded NICs are
enabled by installing an optional NIC hardware key in the ISCSI_KEY socket
on the system board.
CAUTION:
Many repairs may only be done by a certified service technician. You
should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
