5.10.2 - Control Panel LEDs
The control panel located on the front of the OneBlox has several LEDs. These LEDs provide you
with critical information related to different parts of OneBlox. This section explains what each LED
indicates when illuminated and any corrective action you may need to take.
5.10.2.1 - Power Fail
Indicates a power supply module has failed. The second power supply module will take the load
and keep OneBlox running but the failed module will need to be replaced. Refer to Chapter 6 for
details on replacing the power supply. This LED should be off when OneBlox is operating normally.
5.10.2.2 - Information LED
This LED will be blue when the UID function has been activated. When this LED flashes red, it
indicates a fan failure. When red continuously it indicates an overheat condition, which may be
caused by cables obstructing the airflow in OneBlox or the ambient room temperature being too
warm. Check the routing of the cables and make sure all fans are present and operating normally.
You should also check to make sure that the OneBlox covers are installed. Finally, verify that the
heatsinks are installed properly. This LED will remain flashing or on as long as the indicated
condition exists.
5.10.2.3 - NIC1
Indicates network activity on the LAN1 port when flashing.
5.10.2.4 - NIC2
Indicates network activity on the LAN2 port when flashing.
5.10.2.5 - HDD
