4.8 Verifying Normal Operation
After powering up, verify that the HCM/ACM LEDs (see Figure 4-28) indicate normal operation. If the RF source is operational,
also verify that the RIM LEDs (see Figure 4-30
) indicate normal operation.
Note: The LEDs are the same for HCM and ACM modules.
HCM LED Description
PWR Steady green - power input detected by module.
RUN Blinking green – module software up and running
SYS Steady green - overall status of the managed system
is OK
FAN Steady green – normal operation status for all fans
