Unit ID LEDs (LE2/LKE2)
There are two unit ID LEDs on the motherboard, one for each node. Each Unit ID
LED is associated with a Unit ID switch. The Unit ID Switch activates the Unit ID
LED next to it, and the corresponding Unit ID LED on the front panel of the chassis
(if so equipped). This enables a user or a service person to easily identify which unit
is being serviced from behind or in front of the system, a mounting rack or cabinet
by simply looking at what chassis has its Unit ID LED activated.
Main Power LED (LE1/LKE1)
There are two main power LEDs on the motherboard, one for each node. This
LED indicates that power from the power supply is reaching the motherboard (hard
switched, usually on the power supply).
Power/Suspend LED (DP2/DKP2)
There are two Power/Suspend LEDs on the motherboard, one for each node. This
LED indicates that the system is turned on (soft switched). When this LED is blink-
ing, it indicates that the system is on suspend mode.
SATA LED (DKP3/DP3)
There are two SATA LEDs on the motherboard, one for each node. When this LED
is blinking, it indicates activity on the system's SATA port(s).
BMC Heartbeat LED (DKP1/DP1)
There are two BMC Heartbeat LEDs on the motherboard, one for each node.
When this LED is blinking, it indicates that the Baseboard Management Controller
(BMC) is activated.
