3-3 Control Panel LEDs
The control panel located on the front of the chassis has fi ve LEDs. These LEDs
provide you with critical information related to different parts of the system. This
section explains what each LED indicates when illuminated and any corrective
action you may need to take.
Overheat/Fan Fail: When this LED fl ashes it indicates a fan failure. When
on continuously (on and not fl ashing) it indicates an overheat condition, which
may be caused by cables obstructing the airfl ow 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 (see Chapter 5). This LED will remain fl ashing or on as long as
the overheat condition exists.
NIC2: Indicates network activity on GLAN2 when fl ashing .
NIC1: Indicates network activity on GLAN1 when fl ashing.
HDD: Indicates IDE channel activity. On the SuperServer 6015B-8 this
light indicates SCSI and/or DVD-ROM drive activity when fl ashing.
