Table 1 lists the LED indicators on the SRX240 Services Gateway front panel.
Table 1: SRX240 Services Gateway Front Panel Components
Component | Description | Usage |
|---|---|---|
Status LED | The Status LED has the following indicator colors:
| The Status LED can be used to determine whether the device is starting up, is functioning normally, or has failed. |
Alarm LED | The Alarm LED has the following indicator colors:
Note: When the system is up and running, if the Alarm LED is off, it indicates that no alarms are present on the device. | The Alarm LED can be used to gather information on major or minor alarms or to determine if the device is functioning normally. |
Power LED | The Power LED has the following indicator colors:
| The Power LED can be used to determine if the device is receiving power. |
HA LED | The HA LED has the following indicator colors:
| The HA LED can be used to determine if the chassis clustering is enabled on the device. |
Mini-PIM LED | Each Mini-Physical Interface Module (Mini-PIM) LED has the following indicator colors:
| The Mini-PIM LED can be used to determine if the Mini-PIM is present and detected by the device. |
Ethernet Port LEDs
On the SRX240 Services Gateway, each Gigabit Ethernet port has the two LEDs as shown in Figure 2.
Figure 2: SRX240 Services Gateway Port LEDs

Table 2: SRX240 Services Gateway Port LEDs
Number | LED |
|---|---|
1 | TX/RX/Link LED |
2 | PoE (Power over Ethernet) LED |
![]() | Note: The PoE LED is enabled only on the PoE variant of the SRX240 Services Gateway. For non-PoE services gateways, the PoE LED remains off. |
Table 3 describes the Ethernet port LEDs.
Table 3: SRX240 Services Gateway Ethernet Port LEDs
Function | Color | State | Description |
|---|---|---|---|
TX/RX/Link | Green | Blinking | Link is active. Data communication is taking place. |
Steady | Link is active. No data communication is taking place. | ||
Unlit | Off | Link is inactive. | |
PoE Status | Green | Steady | PoE is activated and the connected power device is receiving power. |
Yellow | Steady | PoE is activated, but the connected power device is not receiving power (fault or not enough power). | |
Unlit | Off | PoE is disabled or no device is drawing power. |
Voice Interface Port LED
On the SRX240 Services Gateway, each Voice Interface (FXO and FXS) port has a single LED indicating the status of the port.
Figure 3 shows the SRX240 Services Gateway Voice Interface port LEDs.

Table 4: SRX240 Services Gateway Voice Interface Port LEDs
Number | LED |
|---|---|
1 | FXS1, FXS2 LEDs |
2 | FXO1, FXO2 LEDs |
Table 5 describes the Voice Interface port LEDs.
Table 5: SRX240 Services Gateway Voice Interface Port LEDs
Function | Color | State | Description |
|---|---|---|---|
Voice Interface LEDs | Off | Unlit | Port is inactive. |
Green | Steady | Port is connected and active. | |
Amber | On | Port is active and not ready for data communication. | |
Green | Blinking | Port is active and data communication is taking place. | |
Red | Blinking | Port is initializing. Note: The Voice Interface port LED glows red (blinking) while initializing. If there is an error, the LED remains red; otherwise, changes to green. | |
Red | Steady | Port has detected a hardware initialization failure. |
DC Power Supply Feed LEDs (SRX240 Services Gateway High Memory with DC Power Supply Model)
On the SRX240 Services Gateway High Memory with DC Power Supply model back panel includes two LEDs to indicate the status of DC power supply feed.
Figure 4 shows the DC power supply feed LEDs on the SRX240 Services Gateway High Memory with DC Power Supply model.
