CPU

The CPU LED indicates the operating status of the EMM-E6, and is primarily concerned with the operation of the onboard i960 RISC processor.

NOTE

The STBY, RCV, XMT, and CLN LEDs are in a matrix, which provides these indicators for four of the EMM-E6 Ethernet channels. To read the LEDs, the vertical column indicates the interface or channel the LED designates (D, C, B, or A), while the horizontal row denotes the condition or statistic being monitored.
