Power: Indicates power is being supplied to the system's power supply units. This
LED should normally be illuminated when the system is operating.
HDD: Indicates SAS/SATA drive and/or DVD-ROM drive activity when ashing.
NIC1: Indicates network activity on Gigabit LAN1 when ashing.
NIC2: Indicates network activity on Gigabit LAN2 when ashing.
Informational LED:
Continuously on and blue: UID function has been activated.
Flashing red: Fan failure.
Continuously on and red: Overheat condition. This may be caused by cables
obstructing the airow in the system 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 chassis covers
are installed. Finally, verify that the heatsinks are installed properly. This LED will
remain ashing or on as long as the overheat or fan failure condition exists.
