CHAPTER 4
MONITORING AND TROUBLESHOOTING
This chapter describes how to use the LANVIEW LED system to monitor the operation of the BRIM-T6. It also describes procedures for resolving problems you may encounter establishing a link to a network via the BRIM-T6 interface.
4.1 LANVIEW LEDS
LANVIEW LEDs are Cabletron Systems’ built-in, visual diagnostic and status monitoring system. The comprehensive LANVIEW system for the BRIM-T6 consists of four LEDs (Light Emitting Diodes) on the face of the BRIM-T6 and one LED on the face of its attached TPIM (Figure 4-1).

4.1.1 Describing BRIM-T6 LEDs
The information conveyed by each LED about the operational status of the BRIM-T6 is described as follows (also see Table 4-1 summary):
16Mb (Ring Speed)
When solid Yellow, 16Mb indicates that the BRIM-T6 ring speed is set to 16 Mbps. When off, it indicates that the ring speed is set to 4 Mbps.
