The buttons and LED indicators for the depicted icons func-
tion as follows:
Overheat/Fan Fail
(icon) – This LED is unlit
unless the chassis is overheated. A flashing red
LED indicates a fan failure. A steady red LED (on
and not flashing) indicates an overheating condi-
tion, which may be caused by cables obstructing
the airflow in the system or the ambient room tem-
perature being too warm.
NIC2
(icon) – A flashing green LED indicates net-
work activity on LAN2. The LED is a steady green
with link connectivity, and unlit if there with no link
connectivity.
NIC1
(icon) – A flashing green LED indicates net-
work activity on LAN1. The LED is a steady green
with link connectivity, and unlit if there with no link
connectivity.
HDD
(icon) – In addition to displaying in the control
panel, this icon also displays on the front panel on
each hard drive carrier. Hard drive activity is indi-
cated by a flashing amber LED in the control
panel, and a flashing green LED on a drive carrier.
An unlit LED on a drive carrier may indicate a hard
drive failure. (See Hard drive failure in the Trouble-
shooting sub-section for information on detecting a
hard drive failure and resolving this problem.)
Power
(icon) – The LED is unlit when the server is
turned off. A steady green LED indicates power is
being supplied to the unit’s power supplies. (See
also Rear of chassis.) (See Power supply failure in
the Troubleshooting sub-section for information on
detecting a power supply failure and resolving this
problem.)
