Table 4-1. Remote Annex 5393/PRI Front Panel LEDs

LED(s) Description
Annunciator The Annunciator backlights the model number of the
module and indicates, by its color, the operational
condition of the module. The conditions are:
Green - The module is performing normally.
Amber - Some portion of the module has failed, or the
module is being initialized.
Off - The module is not receiving +5 volt power, or the
power level is below the reset limit (4.65 volts).
Segment These LEDs indicate which backplane Ethernet LAN
Connection segments are being used. There are 12 green LEDs,
labeled S1 through S12, for the 12 Ethernet segments.
When an LED is illuminated, it indicates that the
Remote Annex is connected to the corresponding
backplane Ethernet LAN segment; when off it indicates
that the corresponding backplane Ethernet LAN
segment is not connected.
Module Status Init - Turns green when the Remote Annex begins the
initialization process after a power-up or reset. This is
the first LED that lights after power-up or reset. The
Init LED turns off after the diagnostics have
successfully completed.
Unit - Turns green after the Remote Annex passes the
power-up diagnostics. Turns amber if the power-up
diagnostics fail.
Net - Turns green after the Remote Annex verifies that
a valid Ethernet connection exists.
