Using Beaconing
The beaconing feature enables you to force a specific adapter’s LEDs to blink in a particular sequence.
The blinking pattern acts as a beacon, making it easier to locate a specific adapter among racks of other
adapters. (Not available in read-only mode.)
When you enable beaconing for LightPulse adapters, the two LEDs blink rapidly in unison for 24
seconds, after which the LEDs report the adapter health status for 8 seconds. When the 8 seconds are
up, the adapter returns to beaconing mode. This cycle repeats indefinitely until you disable this feature
or you reset the adapter.
When you enable beaconing for OneConnect adapters, the two LEDs blink rapidly in unison until you
disable beaconing.
To enable or disable beaconing:
1. From the discovery-tree, select the adapter port whose LEDs you want to set.
2. Select the Diagnostics tab and click Beacon On or Beacon Off.
Saving the Log File
You can save the test log to a log file for later viewing or printing. When new data is written to a saved
file, the data is appended to the end of the file. Each entry has a two-line header that contains the
identifier of the adapter being tested and the date and time of the test. Over time, the data accumulates
to form a chronological history of the diagnostics performed on the adapter. (Not available in read-only
mode.)
The default location is:
• In Windows: the OneCommand Manager application install directory on your local drive
• In Solaris: /opt/ocmanager/Dump
• In Linux: /usr/sbin/ocmanager/Dump
Note: The beaconing buttons are disabled if the selected adapter does not support
beaconing.
