MONITORING AND TROUBLESHOOTING

This chapter describes LANVIEW LED functions and color codes and

how to use LEDs to monitor and troubleshoot the operational status of the

TRBMIM-T. It also describes how to monitor the system start-up, or

initialization, process using the Power Up Diagnostic screen. The chapter

concludes with a troubleshooting checklist.

The LANVIEW LED system for the TRBMIM-T comprises three sets of

LEDs. Each set conveys information about the operating status of a

particular TRBMIM-T functional entity:

•

The operating system and system-hardware components

•

The Station port (including the TPIM LNK LED)

•

The FNB ring

LED functional states are described as follows:

Off

Blinking

Flashing

Solid

Indicates either that the TRBMIM-T is not

activated when all LEDs are off, or a particular

condition indicated by an LED when the

TRBMIM-T is activated; for example, "the

LED is off under normal operating

conditions . . . ."

Emits a color synchronously; for example, "the

LED blinks green to indicate . . . ."

Emits a color asynchronously; for example,

"the LED ﬂashes red to indicate . . . ."

Emits a solid, non-blinking, non-ﬂashing color;

for example, "the LED is solid yellow to
