Chapter 2 Installing the Model 5399 Remote Access Concentrator Module
The Model Remote Access Concentrator performs a series of
self-test diagnostics each time it is reset or powered up. These
tests take about a minute to complete and cannot be deactivated.
While these tests are running, the annunciator remains amber.
The annunciator changes to green upon successful test
completion. For information about possible error conditions, see
Chapter 4.

When the Remote Access Concentrator is operating correctly, the
front-panel LEDs (see
• Annunciator: The annunciator should be green. If the
annunciator remains amber after completing the self-tests,
refer to
Chapter 4
• Segment Connection LEDs: A steady green indicates which
Ethernet LAN segment the module is using.
• Module Status LEDs:
• Init: Turns green when the module begins the
initialization process after a power-up or reset. Typically,
this is the first LED that lights after power-up. The Init
LED turns off after the initial diagnostics have
successfully completed.
• Unit: Turns green after the module passes the power-up
diagnostics. If the Unit LED turns amber, refer to
Chapter 4

Ethernet connection exists.
