This section describes the LEDs used to confirm and troubleshoot operation of the Catalyst 2900 modules. The LEDs on the supervisor engine module indicate the system power and processor status; LEDs on the switching modules indicate the status of the individual switching module and their interfaces.
When the Catalyst 2900 is plugged in it runs a series of diagnostic tests. During this period, the status LED is orange. If the switch passes all the tests, the status LED is green. If any tests fail, the status LED turns red. The status LED will also be orange when it is explicitly disabled with the system software.
The LEDs on the supervisor engine module reflect how the system's various components are operating and are described in Table 7-1. For a description of the power supply shutdown conditions and threshold status levels, refer to the section "Environmental Monitoring" in the chapter "What Is the Catalyst 2900?."
The supervisor engine module LEDs are shown in Figure 7-1.
Figure 7-1 : Supervisor Engine Module LEDs
Table 7-1 : Supervisor Engine Module LEDs
| LED | Description |
|---|---|
| Status | The switch performs a series of self-tests and diagnostic tests.
If all the tests pass, the status LED is green. If any test fails, the status LED is red. During system boot or if the module is disabled, the LED is orange. |
| Fan | Indicates whether or not the fans are operational.
If the fans are operational, the fan LED is green. If the fans are not operational, the fan LED is red. |
| PS | If the power supply is operational, the PS LED is green.
If the power supply detects an anomaly, the PS LED is red. |
| 100 Mbps | Green---Indicates that the port is operating at 100 Mbps. |
| Link | Green---The port is operational.
Orange---The link has been disabled by software. Orange flashing---The link is bad and has been disabled. Off---No signal is detected. |
The switch load-meter LEDs provide a visual indication (as an approximate percentage) of the current traffic load over the backplane. (See Figure 7-2.)
The LEDs provide status information for the module and individual 10/100 Mbps Fast Ethernet interface connections. The LEDs are shown in Figure 7-3 and described in Table 7-3.

Table 7-2 : 10/100 Mbps Fast Ethernet Module LED Descriptions
| LED | Description |
|---|---|
| Status | The switch performs a series of self-tests and diagnostic tests.
If all the tests pass, the Status LED is green. If any test fails, the Status LED is red (or orange for a minor fault). During system boot or if the module is disabled, the LED is orange. During self-test diagnostics, the LED will be orange. If the module is disabled, the LED will be orange. |
| 100-Mbps | Green ---Indicates that the port is operating at 100-mbps. |
| Link (bottom LED) | Green ---Indicates the port is operational (signal detected).
Orange---Link disabled by software. Orange flashing---Port bad and disabled (hardware failure). Off---No signal detected. |
The LEDs on the faceplate of the Fast Ethernet switching module (100BaseFX 12 port), shown in Figure 7-4, are described in Table 7-3.
Table 7-3 : 100BaseFX LED Descriptions
| LED | Description |
|---|---|
| Status | The switch performs a series of self-tests and diagnostic tests.
If all the tests pass, the status LED is green. If any test fails, the status LED is red (or orange for a minor fault or if manually disabled). |
| Link | Green---the port is operational.
Orange---the link has been disabled by software. Orange flashing---the link is bad and has been disabled. Off---no signal is detected. |
Enter the ping command to send Internet Control Message Protocol (ICMP) echo request packets to another node on the network to confirm the connection to that node.
Syntax Description
| -s | Causes ping to send one datagram per second, printing one line of output for every response received. The ping command does not return any output when no response is received. |
| host | The IP address or IP alias of the host. |
| packet_size | (Optional) The number of bytes in a packet, from 1 to 2,000 bytes, with a default of 56 bytes. The actual packet size is eight bytes larger because the switch adds header information. |
| packet_count | (Optional) The number of packets to send. |
Usage Guidelines
Enter Ctrl-C to stop pinging.
Following are sample results of the ping command:
no answer
message appears in ten seconds.
Example
In the following example, a host with IP alias elvis is pinged a single time, then pinged once per second until Ctrl-C is entered to stop pinging:
Console> ping elvis elvis is alive Console> ping -s elvis ping elvis: 56 data bytes 64 bytes from elvis: icmp_seq=0. time=11 ms 64 bytes from elvis: icmp_seq=1. time=8 ms 64 bytes from elvis: icmp_seq=2. time=8 ms 64 bytes from elvis: icmp_seq=3. time=7 ms 64 bytes from elvis: icmp_seq=4. time=11 ms 64 bytes from elvis: icmp_seq=5. time=7 ms 64 bytes from elvis: icmp_seq=6. time=7 ms ^C ----elvis PING Statistics---- 7 packets transmitted, 7 packets received, 0% packet loss round-trip (ms) min/avg/max = 7/8/11 Console>
Enter the show system command to display the power supply, fan, temperature alarm, system, and modem status; the number of days, hours, minutes, and seconds since the last system restart; the baud rate; the MAC address range; and the system name, location, and contact.
Example
In the following example, the system status and other information is displayed:
