Each type of module (route controller, router, bay controller, and cooling) executes an automatic Power-On Self Test (POST). The test runs when you seat the module in a slot, power cycle the module, or restart the QSR system.
Module LEDs indicate if the module passes or fails POST.
If the initial POST fails, attach a laptop PC or a console to the module and display the POST results. POST results provide specific information about how the module failed and can indicate how to rectify the error.
NOTE Cooling modules do not provide a console port.
This chapter describes:
- POSTs for each type of module
- LEDs for each type of module
- Procedures for restarting modules
WARNING (W:A-1) This is a Class 1 laser product. Invisible laser radiation can be emitted from the aperture of a port when the fiber cable is disconnected. Avoid exposure to laser radiation and do not look directly into open apertures.
Route Controller Module POST
The route controller module POST is a memory check only. This POST is a silent process and displays no messages on an attached console.
Route Controller Module LEDs
Each route controller module has four LEDs on the faceplate. The color and state of the LED indicate the status of the route controller module.
Figure A-1. Locating Route Controller Module LEDs
During route controller module POST, the Redundant LED on the faceplate blinks amber. All other LEDs remain off. When POST is completed successfully, LEDs light or blink green. (See the QSR Route Controller Module Field Replacement Procedure, Part No. 05148-00, for details about LED states.)
LEDs on the faceplate indicate the following POST conditions:
- Blinking amber, Redundant LED - POST is in process.
- Solid red, all LEDs - POST detected a nonrecoverable error or fault. If the red LEDs remains lit, restart the route controller module by unseating and reseating the module.
- Solid amber, all LEDs - POST is unable to run due to a major malfunction. Try reseating the module. If the LEDs remain solid amber, replace the route controller module.
- Unlit, all LEDs - no power is reaching the module. Check power connections and breaker switches. If LEDs do not light after reseating the module, replace the module.
NOTE NOTE To test the functionality of the LEDs, press the LAMP TEST button on the faceplate.
Restarting a Route Controller Module
Some POST failures are due to an improperly seated route controller module or other simple problem. Unseating and reseating the module causes the module to power on/power off and rerun the POST and may clear the problem.
CAUTION (C:A-1) When unseating the module, pull it out no more than a half inch from its seated position. You must take care not to stress the cables.
Do not use the ejector latches to lift or adjust the module in the slot. Doing so can damage the equipment.
PROCEDURE: If a failure occurs during route controller module POST (the red LED remains lit), use the following procedure to unseat and reseat the module:
Step 1 Verify that the wrist strap you are wearing is properly grounded.
Step 2 Leave all cables attached to the route controller module.
Step 3 Unlock module latches by doing the following:
- Gently press in the edge of both ejector latches.
- Slide the release lever in the direction specified by the arrows.
- Rotate the latches to open them.

The route controller module re-executes POST. If POST fails again, contact Avici Customer Service. See "Support Services" in the Preface for Avici Customer Service contact information.
Router Module POST
The router module POST has three stages, in which it does the following:
- Stage 1 - checks the router module boot ROM.
- Stage 2 - tests the central processor hardware on the router module.
- Stage 3 - restarts the router module and loads an operational image from flash memory.
POST must successfully complete each stage before continuing to the next one.
Router Module LEDs
The router module has one round green LED and one triangular red LED on the faceplate. Refer to Figure A-6.
Figure A-6. Locating Router Module LEDs
During router module POST, the red LED lights and remains lit until POST is completed. After POST completion, the green LED blinks and the red LED goes out. LEDs indicate the following:
- Blinking green LED - the module passed POST and is operational.
- Solid red LED - POST detected a nonrecoverable error or fault. If the red LED remains lit, unseat and reseat the module to rerun POST.
Restarting a Router Module
Some POST failures are due to an improperly seated module or other simple problem. Unseating and reseating the module may clear the problem.
PROCEDURE: If a failure occurs during router module POST (the red LED remains lit), use the following procedure to unseat and reseat the router module:
Step 1 Verify that the wrist strap you are wearing is properly grounded.
Step 2 Leave all cables and fibers attached to the router module.
Step 3 Unlock the ejector latches by simultaneously doing the following to both the top and bottom latch:
- Gently press the edge of the latch towards the faceplate.
- Slide the release lever in the direction specified by the arrow.
- Rotate the ejector latches away from the unit to open them. See Figure A-7.
Figure A-7. Unlocking the Ejector Latches
CAUTION (C:A-2) Do not use the ejector latches to lift or adjust the module in the slot. Doing so can damage the equipment.
Step 4 Carefully pull the module out of the slot about a half inch until you unseat the module from the backplane.
Step 5 Rotate the ejector latches to the closed position. Slide the release levers back until the levers lock.
Step 6 Gently slide the module back into the slot until the ejector latch hits the outer lip of the shelf. Refer to Figure A-8.

The router module re-executes the POST. If POST fails again, contact Avici Customer Service. See "Support Services" in the Preface for Avici Customer Service contact information.
Bay Controller Module POST
The bay controller module boot process run through the following three stages:
- Stage 1 - bootROM checks memory and NVRAM.
- Stage 2 - the bay controller module loads the operational system image. The image loaded can be either a system image to operate the bay controller module or a POST image to test the bay controller module.
- Stage 3 - the operational system image loaded in stage 2 starts running.
Bay Controller Module LEDs
Each QSR bay controller module has three status LEDs on the module faceplate. Refer to Figure A-11.
Figure A-11. Locating Bay Controller Module Status LEDs
The LEDs blink and go out to indicate the status of the bay controller module as it comes up.
- In stage 1, the green LED lights during the hardware POST. A red LED in stage 1 indicates a hardware error. Use the procedure described in "Restarting a Bay Controller Module" to restart the module.
- In stage 2, the green LED remains lit while the operational image loads.
- In stage 3, the green LED blinks to indicate proper operational status.
Restarting a Bay Controller Module
If the bay controller module POST fails (the red LED remains lit), a hardware failure occurred. Some failures are due to an improperly seated bay controller module or other simple problem.
Use the following procedure to unseat and reseat the bay controller module. If you remove a bay controller module completely, inspect the VHDM connector for deformed pins, holes between socket columns, or distorted guide fins before re-inserting the module.
NOTE This procedure causes the module to power off, power on, and rerun the boot process.
Step 1 Pull the ejection/insertion latches to the open position (at a 90° angle to the faceplate) to release the bay controller modules.
Step 2 Pull the module about half an inch out of the bay to unseat the backplane connectors. Refer to Figure A-12.
Figure A-12. Removing the Bay Controller Module
Step 3 Wait approximately 10 seconds for the module to power down completely.
Step 4 Carefully push the module into the slot until you reseat the modules connectors in the backplane, keeping the ejection/insertion levers at right angles to the module faceplate.
Step 5 Close the ejection/insertion tabs to lock the module in place.
- The bay controller module is restarted and the boot process rerun. If POST again fails, contact Avici Customer Service.
Example: The following example shows annotated console output of a successful bay controller module boot.
Hardware POST checks NVRAM and boot ROM starts. The green LED lights and remains lit.
Hardware POST finishes and bootROM continues.
CPU: AVICI Flint - PowerPC 860
BOOTROM OS: IPriori, Release 5.1
Release: 6.5
Creation date: Nov 14 2002, 15:17:00
Build name: Platform: sb; Label: SB_BL6.5
When the Boot ROM is completed, operational (or POST) image loading starts. The green LED remains lit.
When the bay controller module is operational, the green LED blinks slowly.
Troubleshooting a Bay Controller Module
Two types of bay controller module failures include:
- Unrecoverable hardware failures that cause the red LED to light.
- Operational anomalies that do not cause the red LED to light.
If the red LED remains lit after restarting the module, a fatal hardware error occurred. Replace the bay controller module.
Cooling Modules
Address cooling module failures immediately. Lack of proper cooling adversely affects QSR system performance.
Cooling Module LEDs
The QSR cooling system consists of two removable cooling modules located behind the air intake assembly at the top of the QSR system. Each module contains three fans and three LEDs located on the faceplate. The LEDs indicate the status of each fan in the assembly.
Figure A-13 shows the location of the cooling module LEDs.
Figure A-13. Locating Cooling Module LEDs
On power up, the LEDs go through the following cycle:
- Blink red initially
- Light a steady green shortly thereafter
- Blink slowly when communication is established and the blowers are operating under the control of the bay controller module
When power up is complete, cooling module LEDs indicate the following:
- Unlit LEDs - power to the cooling module is lost.
- Blinking green LEDs - the cooling module is running under the control of the bay controller module.
- A red LED - a failure is detected. Replace the fan module.
- A green LED - no communication has occurred with the bay controller module for 5 or more seconds. The fan runs in autonomous mode. An internal thermistor determines fan speed.
Replacing a Cooling Module
This section describes how to replace a cooling module.
To access cooling modules, you must remove the QSR faceplate.
Removing the QSR Faceplate
