3.2.1 What the Blinking Lights Mean
3.2.1.1 The Green LED
During the initial boot up the green LED may blink unevenly. However after 10
seconds the green LED should begin blinking at a steady rate of 1/2 second on
and 1/2 second off. This is considered the node’s “heartbeat.” If the green light
fails to come on, is a solid green, or flashes at any other rate, the node has
malfunctioned and the node must be replaced.
3.2.1.2 The Red LED
During the initial boot up the red LED may blink unevenly. During system
operation the red LED will be a solid red whenever it is communicating with any
other Eka node. If the red light flashes continuously, the node has malfunctioned
and the node must be replaced.
