Chapter 5. Monitoring the system using LEDs
The section provides information about LED based monitoring of IBM Elastic Storage System 3200. The
chapter guides customers to use LEDs for monitoring and maintenance of the system.
The following components of IBM Elastic Storage System 3200 support LED-based monitoring:

System status LEDs
System status LEDs provide status of IBM Elastic Storage System 3200.
Ten status LEDs are available along the upper-left edge on the front of the enclosure, just above the drive
bays as shown in Figure 73 on page 83. From left of the enclosure, the first three LEDs provide status of
FRUs that are not visible from the cold aisle—the fans, server canisters, and power modules.
The next six LEDs provide status of FRU groups and direct the user to the appropriate FRU for further
investigation when there is a fault. The last LED on the enclosure is not in use.
The following figure shows system status LEDs on an IBM Elastic Storage System 3200 enclosure:
