Introduction
The purpose of this document is to explain the various reasons that can cause an ASP Status LED to turn red. It also describes the power-on diagnostics (PoD), as well the various show diag power-on command output fields.
Observe the LEDs of all ports at bootup to see that online tests are conducted one at a time. The ATM Switch Processor (ASP) conducts various diagnostic tests. If an error is detected within the tests, the Status LED under ASP turns red. The Status LED usually changes color after bootup.
If the ASP Status LED turned red, you can use the show diag power-on command to determine the precise reason. The output slightly varies for each feature card type.
Note: Individual line cards on your ATM switch also use LEDs to indicate status information. A red LED on line cards is not discussed in this document. Refer to the ATM and Layer 3 Module Installation Guides to troubleshoot a red status LED on a specific line card.
The test is not performed systematically when the LS1010 boots. It is done when the box is powered up, but not when it is re-loaded afterwards.

You can also see that Frame Relay/ATM cards are displayed in different ways, which can also be seen with the PCQ.
Whatever the output type, the main indication is that the PoD passed. If it had failed, the ASP Status LED would be red. If recoverable errors are seen in the tests, the tests perform normally, but a warning displays as in this example:

Field Definitions
These tables explain only the fields related to the ports or memory. You can assume that any other test failures involve the replacement of the ASP. This includes diagnostics under the MMC, FC-PFQ, or feature card.
|
Chassis-Specific Fields |
|
|---|---|
|
Field |
Definition |
|
BOOTFLASH |
This performs validation on the files present in the CPU-board-resident flash file system. This checks the presence of file system and checksum validation for the bootflash resident files. If it fails, the bootflash is bad. Reformat it with the LS1010 and recopy the files with the copy tftp command. Refer to Recovering from a Corrupted or Lost Cisco IOS Image on LS1010 and Catalyst 8500 Switches. |
|
PCMCIA-Slot[0 or 1] |
This is the same as the bootflash test. |
|
[CPU or Fcard]IDPROM |
This performs validation of the CPU/Feature Card IDPROMS. If it fails, you will need to Return Material Authorization (RMA) the ASP. |
|
NVRAM-Config |
This performs validation of the NVRAM. If it fails, try to configure the LS1010 with the IOS config mode commands. If it still fails, replace the ASP. |
|
SRAM |
This performs the Read/Write test on Static memory, which is 128K in size. If it fails, replace the ASP. |
|
DRAM |
This performs the Read/Write test on Dynamic memory. Replace DRAM; if it still fails, replace ASP. |
|
PS [1 or 2] |
This is the power supply. |
|
FAN |
This is self-explanatory. |
|
Temperature |
This is self-explanatory. |
|
Bkp-IDPROM |
This performs validation on the backplane IDPROM. Replace the chassis. |
|
Card-Specific Fields (FC-specific Test Skipped) |
|
|---|---|
|
Field |
Definition |
|
Access |
This test makes sure that the PHY-layer HW resident on the various port adapter module (PAM) cards in the system are accessible. If it fails, replace the PAM. |
|
Interrupt |
This test makes sure that the PHY-layer HW resident on the various PAM cards in the system can interrupt the CPU under alarm condition. If it fails, replace the PAM. |
|
Loopback |
This test sources the unicast cells to the port and validates the received cells in loopback mode. If it fails, the connectivity is broken in the cell path. Try to replace the PAM first. |
|
CPU-MCast |
This is the same as the loopback test for multicast cells. In other words, the CPU acts as the root of the point-to-multipoint connection. |
|
Port-MCast |
The CPU sends a unicast cell to the first port in the list, which in turn multicasts it to the rest of the port and validates the result in the loopback mode. |
|
Ethernet-Specific Counters |
|
|---|---|
|
Field |
Definition |
|
Ethernet-port Access |
This test ensures that the Ethernet port HW resident on the Ethernet controller present on the ASP is accessible. If it fails, the Ethernet controller seems to be broken, and the ASP needs to be replaced. |
|
Ethernet-port CAM-Access |
This performs Read/Write on the built-in Content Addressable Memory (CAM) on the Ethernet controller. If it fails, the Ethernet controller seems to be broken, and the ASP needs to be replaced. |
|
Ethernet-port Loopback |
This performs the loopback test on the Ethernet port. If it fails, the Ethernet controller seems to be broken, and the ASP needs to be replaced. |
|
Ethernet-port Loadgen |
This artificially loads the Ethernet port. If it fails, the Ethernet controller seems to be broken, and the ASP needs to be replaced.. |
SNAKE Test Failures on FC-PFQ
The SNAKE test sends a cell through all interfaces on the switch. This test ensures that all interfaces and associated fabric interfaces are functional. Cisco bug ID CSCdk54678 resolves a problem that causes the SNAKE test to fail on an LightStream 1010, runs Cisco IOS® Software Release 11.3WA4, and uses an FC-PFQ.
Recommendations
If you see a failed PoD caused by a PAM (from the show diag power-on output), we highly recommend that you perform these steps in order until the problem is resolved:
-
Upgrade the Cisco IOS software to a more recent release (Version 12.0 or higher) since some bugs have been resolved.
-
Turn the LS1010 off, re-seat the PAM, and turn the LS1010 on again because an improperly-inserted PAM can definitely cause the tests to fail.
-
If all else fails, contact Cisco TAC.
Conclusion
This is a typical example of a Pod that fails. It was solved by an RMA of the PAM. Similar issues have been solved with the PAM reseated.
