Network Port and Uplink Module Port LEDs in EX4500 Switches
Each network port and uplink module port on an EX4500 switch has two LEDs that indicate link/activity and status. The figures in this topic show the location of these LEDs:
- Figure 1 shows the location of the LEDs on the network ports on the front panel of an EX4500 switch. The LEDs point toward the port to which the LEDs belong.
- Figure 2 shows the location of the LEDs on the uplink module ports on the SFP+ uplink module.

Figure 2: Uplink Module Port LEDs
The LEDs labeled Link/Activity LED in Figure 1 and Figure 2 indicate link activity.
Table 1 describes the Link/Activity LED.

LED | Color | State and Description |
|---|---|---|
Link/Activity | Green |

The Status LED in Figure 1 and Figure 2 indicate the status of one of the three port parameters. The port parameters are administrative status, duplex mode, and speed.
Table 2 describes the Status LED on network ports and uplink module ports in EX4500 switches. From the Idle menu of the LCD, use the Enter button on the LCD panel to toggle between the ADM, DPX, and SPD indicators.
Table 2: Status LED on Network Ports and Uplink Module Ports in EX4500 Switches
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 status indicators for network ports on the front panel are:
The uplink module ports are always set to full-duplex mode; therefore, the LED is always green. | |
LED: SPD | Indicates the speed. The speed indicators are:
