3.2 Status-indicating LEDs
3.2.1 Brief Overview of the LEDs
The following devices come with LEDs that inform subsystem managers about the
operational status of the component on which they are mounted. The EonStor
subsystems feature status-indicating LEDs distributed over the active components in
the following ways:

3.2.2 Controller Module LEDs
The rear-facing faceplate of the RAID controller module is shown in Figure 3-1 for
model A12U-G2421. The rear-facing faceplates on the two models look identical.
The LEDs are numbered from 1 to 5. There are two more LEDs on the Ethernet port.
The definitions are shown in Table 3-2 below.
