This chapter describes the LEDs used to confirm and troubleshoot operation of the route processor and interface modules, and includes the following sections:
When these conditions are met, the hardware installation is complete. If the startup sequence fails before these conditions are met, use the procedures in this chapter to isolate and, if possible, resolve the problem.
If you are unable to solve the problem, contact a customer service representative for assistance and further instructions. Before you call, gather the following information:
When you have completed the troubleshooting procedures in this chapter, continue with the following interface module troubleshooting steps:
The flowchart in Figure 4-1 helps you determine which component of your device might have malfunctioned.
The LEDs on the route processor indicate the status of the processor, the fan assembly, and the power supplies. The route processor LEDs are shown in Figure 4-2 and described in Table 4-1.
| LED | Color | Description |
|---|---|---|
Status | Green | The system has passed internal self-tests and diagnostic tests. |
| Red | The system has failed internal self-tests and diagnostic tests. |
| Orange | The system is booting or a module is disabled. |
Fan | Green | The fan is operational. |
| Red | The fan is not operational. |
PS 0, left bay | Green | The power supply is operational. |
| Red | The power supply is installed but not operational. |
| Off | The power supply is not installed. |
PS 1, right bay | Green | The power supply is operational. |
| Red | The power supply is installed but not operational. |
| Off | The power supply is not installed. |
Link | Green | The Ethernet port is operational. |
| Off | No signal is detected on the Ethernet port. |
Rx (Receive) | Flashing green | Ethernet packets are being received. The pulse rate increases with the data rate. |
| Off | No signal is being received. |
Tx (Transmit) | Flashing green | Ethernet packets are being transmitted. The pulse rate increases with the data rate. |
| Off | No signal is being transmitted. |
The LEDs on the faceplate of the interface modules provide status information for the individual interface connections. The following sections describe the interface module LEDs.
The LEDs for an unshielded twisted-pair (UTP) Ethernet interface module are shown in Figure 4-3 and described in Table 4-2.
| LED | Color | Description |
|---|---|---|
Rx (Receive) | Green | Port is receiving a packet, the LED is green for approximately 50 ms. |
Off | No signal is detected. | |
Tx (Transmit) | Green | Port is transmitting a packet, the LED is green for approximately 50 ms. |
Off | No signal is detected. | |
LINK | Green | Port is operational (a signal is detected). |
Orange | The link has been disabled by software. | |
Flashing Orange | The link has been disabled by a hardware failure. | |
Off | No signal is detected. | |
100 Mbps | Green | Port is operating at 100 Mbps. |
Off | Port is operating at 10 Mbps. |
The Gigabit Ethernet interface module LEDs are shown in Figure 4-4 and described in Table 4-3.
| LED | Color | Description |
|---|---|---|
Rx-SYNC | Green | This LED reflects the synchronization of the link negotiation process. It is steadily on when there is a gigabit connection. |
Tx (Transmit) | Green | Port is transmitting a packet, the LED is green for approximately 50 ms. |
Off | No signal is detected. | |
Rx-LOSS | Green | This LED indicates the detection of an optical signal from another Gigabit Ethernet device. It is steadily on when there is a gigabit connection. |
LINK-ON | Green | Port is operational (a signal is detected). |
Off | No signal is detected. | |
Rx (Receive) | Green | Port is receiving a packet, the LED is green for approximately 50 ms. |
Off | No signal is detected. | |
Rx-FULL | Green | This LED is on when the port is operating in full-duplex mode, which is always the case for an operational Gigabit Ethernet port. |
