Front control panels on SL units

Control panel buttons, icons, and LED indicators display on
the right side of the front panel. The buttons let you perform
a function on the unit, while an LED indicator corresponding
to an icon alerts you to the status of that feature on the unit.
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.
