Checking drive status LEDs
The quickest way to check drive status if you are near the device is to simply look at
the hard drive status LED indicators, then use the other LED indicators to help
diagnose any problems that might exist.
Figure 19:
Drive status LEDs
1. System Status
2. Global RAID
3. HDD status LEDs
Each drive slot on the LenelS2 EVA 54 has a single corresponding HDD Status LED,
the LED display is located on the front panel. In addition to these, pay attention to the
System Status and Global RAID LEDs to get an idea of what might be wrong with the
affected hard drive.
Table 6: Status LED behavior
HDD Status
One LED for each HDD carrier. Each LED lights GREEN when healthy, RED if
the RAID member is offline or there is a physical disk error, ORANGE indicates
the drive is rebuilding, and a dark LED indicates either no drive is installed or
the drive is not configured. A RED LED here means that drive should be
replaced.
System Status
Lights GREEN when healthy, RED if there is a critical problem (LD offline, fan
malfunction, PSU malfunction, voltage out of range, system temperature alert),
remains dark when not ready.
Global RAID
Status
Lights GREEN when healthy or RED if any RAID volume is offline, ORANGE
for critical state of any logical drive. If a hard drive has failed, this will be
ORANGE. In this case, it will be necessary to replace the affected drive and
rebuild the affected RAID volume.
The Alarm buzzer sounds
When you first power-up LenelS2 EVA 54 beeps twice to show normal operation.
The audible alarm sounds at other times to inform you that the system needs
attention. But the buzzer alarm is not specific. Check the device LEDs and Events
displays or logs for more information.
When the alarm sounds:
Check the front and back of the enclosure for red or orange LEDs.
