被丢弃的数据的数量增加。丢弃的数据包显示在Station Manager Tallies中。如果由于速度不匹配而导致大量数据包丢失，那么限制ETM001（-Kxxx）的速度以匹配更大的网络可能很有用。使用具有更多分组缓冲存储器的交换机可以更好地处理系统中的速度变化。图8:IC695ETM001 Kxxx PACSystems上的以太网端口连接器™ RX3i和RSTi EP TCP/IP以太网通信用户手册第3节GFK-2224Y 2019年8月安装和启动：RX3i以太网接口模块LED上的以太网模块接口30 3.1.3 LED提供以太网模块操作状态和端口链路状态的直观指示。第2.1.1章以太网端口LED操作中描述了LED及其操作。3.1.4以太网LED以太网模块具有指示以太网接口状态和状态的LED：ETM001 Jx以太网模块的以太网端口具有两个LED。底部LED是链路速度LED。此LED在100 Mbps时亮起，在所有其他速度下熄灭。顶部的LED是链接/活动LED。当以任何速度存在链接时，此选项都将打开。当有入站或出站流量时，顶部led将闪烁。ETM001 Kxxx以太网模块的以太网端口上没有LED。以太网通信速度在模块的前面板显示器上显示，离散LED指示10/100/1000 Mbps通信。3.1.4.1 LAN OK LED操作LAN OK LED指示接入以太网。在正常操作期间，当通过网络向以太网接口发送或从以太网接口接收数据时，LAN OK LED闪烁。当以太网接口未主动访问网络，但以太网物理接口可用且其中一个或两个以太网端口都可操作时，该选项将保持打开。除非发生固件更新，否则它将关闭。3.1.4.2日志空LED操作日志空LED指示以太网接口在正常操作模式下的状态。如果日志清空指示灯熄灭，则事件已输入异常日志，可通过Station Manager界面查看。当未记录任何事件时，日志清空LED在正常操作期间亮起。在其他状态下，日志清空LED熄灭或闪烁，有助于定义模块的操作状态。有关LED行为的更多信息，请参阅第12节：诊断。3.1.4.3以太网OK LED操作以太网OK LED指示模块是否可以正常运行。此LED在正常操作时亮起，在所有其他操作时闪烁。当发生硬件或不可恢复的运行时故障时，ETM001 Jx将闪烁两位错误代码，以识别故障。ETM001 Kxxx将闪烁四位代码。有关故障排除的帮助，请参阅第12.4节“ETHERNET OK/OK LED硬件故障闪烁代码”（ETM001 Jx）。有关ETM001 Kxxx故障排除的帮助，请致电技术支持。PAC系统™ RX3i和RSTi EP TCP/IP以太网通信用户手册第3节GFK-2224Y 2019年8月安装和启动：以太网模块接口31 3.1.4.4以太网端口LED操作（100Mb和链路/活动）以太网模块的正面配有LED，用于指示网络端口的物理连接和网络通信速度。以太网接口模块链路/活动位置链路/活动行为IC695ETM001两个带两个LED指示灯（“100”和“Link”）的以太网端口（1A和1B）位于接口模块的前部。100–LED指示
of data being dropped increases. Dropped packets are indicated in the Station Manager Tallies. If there are significant dropped packets due to a speed mismatch, it may be useful to limit the speed at the ETM001(-Kxxx) to match the larger network. Speed changes in a system may be handled better with switches with more packet buffer memory.

The LEDs and their operation are described in Chapter 2.1.1, Ethernet Port LEDs Operation. 3.1.4 Ethernet LEDs Ethernet modules have LEDs to indicate the state and status of the Ethernet interface: ETM001-Jx The Ethernet module’s Ethernet ports have two LEDs. The bottom LED is the link speed LED. This LED is on for 100 Mbps and off for all other speeds. The top LED is the link/activity LED. This will be on when there is a link at any speed. The top led will blink when there is inbound or outbound traffic. ETM001-Kxxx The Ethernet module’s Ethernet ports will not have LEDs on the ports. Ethernet traffic speed is indicated on the module’s front panel display, with discrete LEDs to indicate 10/100/1000 Mbps traffic. 3.1.4.1 LAN OK LED Operation The LAN OK LED indicates access to the Ethernet network. During normal operation the LAN OK LED blinks when data is being sent or received over the network directed to or from the Ethernet interface. It remains on when the Ethernet interface is not actively accessing the network, but the Ethernet physical interface is available and one or both of the Ethernet ports is operational. It is off otherwise unless firmware update is occurring. 3.1.4.2 LOG EMPTY LED Operation The LOG EMPTY LED indicates the condition of the Ethernet interface in normal operational mode. If the LOG EMPTY LED is off, an event has been entered into the exception log and is available for viewing via the Station Manager interface. The LOG EMPTY LED is on during normal operation when no events are logged. In the other states, the LOG EMPTY LED is either off or blinking and helps define the operational state of the module. For more information on LED behavior, refer to Section 12: Diagnostics. 3.1.4.3 Ethernet OK LED Operation The Ethernet OK LED indicates whether the module can perform normal operation. This LED is on for normal operation and flashing for all other operations. When a hardware or unrecoverable runtime failure occurs, the ETM001-Jx will blink a two-digit error code identifying the failure. The ETM001-Kxxx will blink a four-digit code. For assistance troubleshooting errors , check Section 12.4, ETHERNET OK/OK LED Blink Codes for Hardware Failures (ETM001-Jx). For assistance troubleshooting ETM001-Kxxx, please call Technical Support.
