GROUNDING
Signal and chassis ground are not connected together in the drive. To ensure minimal EM emissions, the user should provide maximum surface contact area when connecting the drive to chassis ground.
FAULT LED OUT SIGNAL
The Fault LED Out signal is driven by an open collector driver capable of sinking 30mA. It is driven low when an internal fault is detected along with both Enable Bypass signals.
READY LED OUT SIGNAL
The Ready LED Out signal is driven by an open collector driver capable of sinking 30mA. It will typically be connected to the cathode of an LED in the enclosure. The Ready LED function is nearly identical to the

-PARALLEL ESI AND SEL_n/P_ESI_n
SEL_n/P_ESI_n are a set of dual purpose pins that are used to convey either a Loop Identifier address or Enclosure Service Information (where this is supported by the backplane) to the SSD.
