7. Observe the status of the LANVIEW LEDs on the EMM-E6. When
the CPU LED is flashing, the STBY (standby) LEDs indicate the
module’s boot state. During this period (up to 5 minutes), the LEDs
cycle through a series of internal diagnostics. (See Figure 3-8)
Figure 3-8. EMM-E6 LANVIEW LEDs
8. After the system boot procedure, the LEDs should be in the following
conditions:
• CPU LED flashing, indicating proper EMM-E6 operation.
• STBY (A, B, C, D) LEDs ON or OFF, depending on the port’s
position in the Spanning Tree Algorithm.
• Appropriate EPIM/BRIM LEDs ON (see section 3.9, Connecting
to the Network, to obtain the appropriate LED status for individual
EPIMs; refer to individual BRIM Guides).
• ON LED lit for the active channel D EPIM.
If the LEDs are not operating in the fashion described above, refer
immediately to Chapter 14, Troubleshooting.
