The LANVIEW LEDs(Figure 4-1) allow quick observation of the network status to aid in thediagnosing of network problems. Refer to Table 4-1 for a description ofthe LEDs.For a functional description of the LANVIEW LED on the optional FastEthernet Interface Module (FE-100TX), refer to Section 4.2.Figure 4-1 2H22-08R SmartSwitch 2208 LANVIEW LEDsNOTEThe terms Flashing, Blinking, and Solid used in the followingtable indicate the following:Flashing indicates an irregular LED pulse.Blinking indicates a steady LED pulse.Solid indicates a steady LED light.
