Network Port LEDs in EX4200 Switches
Each network port on the switch has two LEDs. The four figures in this topic show the location of those LEDs:
- Figure 1 shows the location of the LEDs on the network ports on the front panel.
- Figure 2 shows the location of the LEDs on the uplink module ports on the SFP uplink module.
- Figure 3 shows the location of the LEDs on the uplink module ports on the SFP+ uplink module.
- Figure 4 shows the location of the LEDs on the uplink module ports on the XFP uplink module.
Figure 1: LEDs on the Network Ports on the Front Panel
Figure 2: LEDs on the Uplink Module Ports on the SFP Uplink Module
Figure 3: LEDs on the Uplink Module Ports on the SFP+ Uplink Module
Figure 4: LEDs on the Uplink Module Ports on the XFP Uplink Module
The LEDs labeled Link/Activity LED in Figure 1, Figure 2, Figure 4, and Figure 3 indicate link activity. The LEDs labeled Status LED in Figure 1, Figure 2, Figure 4, and Figure 3 indicate the status of one of the four port parameters. The port parameters are administrative status, duplex mode, Power over Ethernet (PoE) status, and speed.
Table 1 describes the Link/Activity LED.
Table 1: Link/Activity LED on Network Ports
LED | Color | State and Description |
|---|---|---|
Link/Activity | Green |

Table 2 describes the Status LED. From the Idle menu of the LCD, use the Enter button on the LCD panel to toggle between the ADM, DPX, POE, and SPD indicators.
Table 2: Status LED on Network Ports
LED | LCD Indicator | State and Description |
|---|---|---|
Status | LED: ADM | Indicates the administrative status (enabled or disabled). The status indicators are:
|
LED: DPX | Indicates the duplex mode. The uplink module ports are always set to full-duplex; therefore, the LED is always green. The status indicators for network ports on the front panel are:
| |
LED: POE | Indicates the PoE status on switches with PoE-enabled ports. Here the term POE refers to both PoE and PoE+ as applicable. PoE is not enabled on uplink module ports; therefore, the LED for those ports is always unlit. The status indicators for network ports on the front panel are:
| |
LED: SPD | Indicates the speed. The speed indicators for network ports on the front panel are:
The speed indicators for network ports on the SFP uplink module are:
The speed indicators for network ports on the SFP+ uplink module are:
The speed of the XFP uplink module ports is always 10 Gbps; therefore, the LED is always green. |
