LANVIEW LEDs
The front panel LANVIEW LEDs indicate the status of the module and may be used as an aid in troubleshooting. Figure 4-1shows the LANVIEW LEDs of the 9H532-24, 9H533-24, 9H531-24 and 9H539-24 module.
The LED Mode Switch
The 9H532-24 and 9H533-24 have an LED mode switch, located on the front panel, that allows the user to change the function of the switch port LEDs. Refer to Figure 4-1.When the switch is in the UP position, the LEDs indicate the receive (RX) and transmit (TX) status of the Þxed ports. When the mode switch is in the DOWN position, the LEDs indicate at what speed the applicable port is currently operating (10 Mbps or 100 Mbps) and if the applicable port is operating in standard (half) or full duplex mode.
Table 4-4and Table 4-5provide the deÞnitions of the LED states that occur when the LED mode switch is in the UP position. Table 4-6and Table 4-7provide the deÞnitions of the LED states that occur when the LED mode switch is in the DOWN position.
