Jumper Description JT11 Keyed I2C Connector JT12 Individual Drive Fault LED header Type 3-pin keyed connector 8 x 2 header JT13 Universal Asynchronous 4-pin connector Receiver/Transmitter (UART) Comments Out-of-band enclosure management (SES2) Indicates drive faults. There is one LED per port. When lit, each LED indicates the corresponding drive has failed or is in the Unconfigured-Bad state. The LEDs function in a direct-attach configuration (there are no SAS expanders). Direct attach is defined as a maximum of one drive connected directly to each port. Note: This header is used for RAID controllers with internal SAS ports only. For factory and debug use Technical Specifications Table 2.
