Monitoring the AastraLink Status LED
The LED on the front of the AastraLink Pro 160 indicates the current status of the
device. The current LED state also displays on the bottom left of the status bar
each time a WebUI page is refreshed. The table below describes the LED
variations.
LED Color Meaning
Off Power is off.
Steady Green The AastraLink Pro 160 has successfully completed internal hardware
diagnostic tests and is starting up.
Alternating Green/Red The AastraLink Pro 160 is updating its onboard firmware, either because it is
the first time you started up the device, or you just uploaded a new firmware
image.
Warning: Do not interrupt power during the system update, as system
corruption can result.
Flashing Green The AastraLink Pro 160 has successfully booted and is up and running, ready
to process calls.
Alternating Green/Red/Off The AastraLink Pro 160 is running in recovery mode. This sequence occurs if
the last boot attempt failed.
Try rebooting. If the problem persists, use the recovery procedure described in
“Reinstalling System Software Using Recovery Mode” on page 7-11.
Flashing Red The AastraLink Pro 160 is running in a degraded state:
• Flash speed: Slow
(approximately once per second) indicates that the
AastraLink is running normally but that a full-duplex network connection
could not be negotiated. This may limit the system capacity and/or cause
problems with collisions or integrity of the network connection, leading to
problems such as WebUI time-outs and garbled voice-path. Recommend
connecting the AastraLink to a full-duplex Ethernet device, such as a
router or switch, rather than a half-duplex device such as a hub.
• Flash speed: Fast (approximately 5 times per second) indicates a system
error occurred during startup; the AastraLink software was unable to
initialize correctly. Contact Aastra support for assistance with diagnosing
the problem.
