ARX-500 ACM Status LEDs
There are additional status LEDs on the right side of the rear panel that
apply to the ACM board only (not the chassis as a whole):
• ARX-500 NVRAM LED
The following table lists the colors and states for the non-volatile RAM
(NVRAM) LED, also known as the battery-charging LED. These are
labeled NVR.
• ARX-500 alarm and status LEDs
The combined states of the Alarm (ALM) and Status (STAT) LEDs
indicate the status of the ACM. The following table lists these colors and
states.
e System fault
• Solid green indicates normal operation.
• Blinking green indicates degraded
performance.
• Solid yellow indicates a critical or
non-recoverable condition.
• Blinking yellow indicates a non-critical
condition.
• No light indicates POST is running or
the system is off.
f System ID Blinking blue indicates system
identification is active.
No light indicates system identification is
not activated. Use this to help find the
chassis in a densely-populated rack.
Press the ID button on the front panel to
activate the LED on the rear panel.
