POST and Troubleshooting

Each type of module (route controller module, bay controller module, router module, and cooling module) executes an automatic Power On Self Test (POST) when the module is seated in a slot, power cycled, or the TSR II system is restarted.

LEDs on each module indicate if the POST passed or failed.

If the initial power-on 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 the procedure to rectify the error.

NOTE Cooling modules do not provide a console port.

This chapter describes:

• The POST for each type of module
  
  
• The LEDs for each type of module
  
  
• The procedures to restart the module
  
  
• The procedures to attach a laptop PC or a console, restart the module, and run tests to check the module
  
  

Route Controller Module POST

The route controller module POST is a memory check only. The route controller POST is a silent process. No messages are displayed on the route controller module console.

NOTE The route controller module does not have a separately loadable diagnostic image, sometimes referred to as "POST".

Route Controller Module LEDs

During route controller module POST, the red LED on the faceplate lights and remains lights until POST is complete. After completion of POST, the green LED lights and the red LED is extinguished.

The solid green LED indicates that the module has passed POST.

Figure A-1. Route Controller Module LEDs

If the red LED remains lit, POST has detected a nonrecoverable error or fault. If the red LED remains lit, restart the route controller module by unseating and reseating the module.

Restarting a Route Controller Module

Some POST failures are due to an improperly seated route controller module or other simple problems. 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. Care must be taken not to stress the cables.

PROCEDURE: If a failure occurs during route controller module POST (the red LED remains lit), use the following procedure to unseat and reseat the route controller module:

Step 1 Leave all cables attached to the route controller module.

Step 2 To release the module from the backplane, simultaneously rotate the ejector latches to a fully open position and carefully pull the route controller a few inches out of the shelf (see Figure A-2).

Figure A-2. Unseating/Reseating the Route Controller Module

Step 3 Wait approximately 50 seconds for the module to cool down.

Step 4 Slide the route controller module back into the slot until the ejector latch tab slides into position behind the outer lip of the shelf (see Figure A-3).

Figure A-3. /Reseating the Route Controller Module - 1

Step 5 Simultaneously slide the release levers in the direction of the arrows and rotate the ejector latches to the closed position (see Figure A-4).

Figure A-4. Reseating the Route Controller Module - 2

The route controller module POST re-executes. If the POST fails again, contact Customer Service. See "Support Services" in the Preface for Avici Customer Service contact information.

Router Module POST

The router module has a separately loadable diagnostic image, referred to as "POST".

The routing module POST has three stages:

• In stage 1, POST checks the routing module's boot ROM.
  
  
• In stage 2, POST tests the central processor hardware on the routing module.
  
  
• In stage 3, POST restarts the routing module and loads an operational image from flash memory.
  
  

Stages 2 and 3 require the successful completion of the previous stage before they begin.

Router Module LEDs

The router module has one green square LED and one red triangle LED visible on the module faceplate (see Figure A-5.)

Figure A-5. Routing Module LEDs

The following are the router module LED conditions:

• During routing module POST, the red LED on the faceplate lights and remains lit until POST is completed. After completion of POST, the green LED is lit and blinks and the red LED is extinguished.
  
  
• The solid green LED indicates that the module has passed POST.
  
  
• If the red LED remains lit, POST has detected a nonrecoverable error or fault. If the red LED remains lit, remove and reseat the module to run POST again.
  
  

Restarting a Routing Module

Some POST failures are due to an improperly seated routing module or other simple problem. Unseating and reseating the module may clear the problem.

PROCEDURE: If a failure occurs during route controller module POST (the red LED remains lit), use the following procedure to unseat and reseat the router module:

Step 1 Open the thumb latches completely.

NOTE Do not disconnect the Ethernet or fiber optic cables.

Step 2 Carefully pull the module out until the connectors at the back of the module are unseated from the backplane - about 1/2-inch (see Figure A-6.)

Figure A-6. Router Module Installation

Step 3 Wait for approximately 10 seconds to allow the module to cool.

Step 4 Ensure that the cable trays on the router module being re-inserted and on the adjacent router modules are fully closed.

Step 5 Close the thumb latches completely.

Step 6 Align the module with the card guides.

Step 7 Slide the module into the slot until the thumb latch lever hits the lip of the shelf (see Figure A-7.)

Figure A-7. Router Module Insertion - 1

Step 8 Open the thumb latches and slide the module in until the thumb latch levers slide into position behind the lip of the shelf (see Figure A-8).

Figure A-8. Router Module Insertion - 2

Step 9 Push the thumb latches to the closed position to further insert the module and to ensure proper seating in the connector backplane (see Figure A-8).

The router module POST re-executes. If POST again fails, contact Avici Customer Service. See "Support Services" in the Preface for Avici Customer Service contact information.

Bay Controller POST

The bay controller module has a separately loadable diagnostic image, referred to as "POST".

The bay controller module boot process has three stages:

• In stage 1, bootROM checks memory and NVRAM.
  
  
• In 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 or a POST image to test the bay controller.
  
  
• In stage 3, the operational system image starts running.
  
  

Bay Controller LEDs

Each TSR II bay controller module has two LEDs on the module faceplate for indicating status (see Figure A-9).

Figure A-9. Bay Controller Front View LEDs

NOTE You must remove the TSR II's front air intake assembly to see the bay controller module LEDs.

The LEDs blink and go out to indicate the status of the bay controller as it comes up.

The following are the bay controller LED conditions:

• In stage 1, the green LED and red LED turns on 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 on (POST passed - no operational image running) while the operational image loads.
  
  
• In stage 3, the green LED blinks to indicate up status (operational image is running).
  
  
• If the red LED remains lit, restart the bay controller module by unseating and reseating the module.
  
  
• Neither red LED nor green LED: no power
  
  

Restarting a Bay Controller Module

If the bay controller module POST fails (the red LED remains lit), it indicates a hardware failure. Some failures are due to an improperly seated bay controller module or other simple problem.

Use the following procedure to unseat and reseat a bay controller module. Be sure to inspect the VHDM connector each time you remove and re-insert, see "Installing the Bay Controller" for the VHDM inspection procedure.

NOTE This procedure will cause the module to power off/power on and rerun the boot process. To access the bay controller module, it is not necessary to remove the cooling module.

Step 1 Turn all four thumbscrew fasteners on the front grille 1/4 turn counterclockwise.

Step 2 Grasp the face of the grille assembly by the air vents.

Figure A-10. Front Air Intake Assembly

Step 3 Remove the grille assembly and set it aside in a safe place.

Step 4 Pull the ejectors on the bay controller module to the open position to release the latches on the bay controller module.

Step 5 Carefully pull the module out until the connectors at the back of the module are unseated from the backplane - about a 1/2-inch
(see Figure A-11).

Figure A-11. TSR II Bay Controller Module Removal

Step 6 Wait approximately 10 seconds for the module to cool.

Be sure to inspect the VHDM connector each time you remove and re-insert, see "Restarting a Bay Controller Module" for the VHDM inspection procedure.

NOTE This procedure will cause the module to power off/power on and rerun the boot process. To access the bay controller module, it is not necessary to remove the cooling module.

Step 7 Carefully push the module into the slot until the connectors at the back of the module are re-seated in the backplane.

Step 8 Push the ejector tabs to the closed position to lock the module in place.

The bay controller restarts and the boot process reruns. If POST again fails, contact Avici Customer Service.

Step 9 Align the grille assembly with the four holes on the chassis which accept the 1/4 turn thumbscrews.

Step 10 Tighten the four thumbscrews 1/4 turn clockwise.

Example: The following example is annotated console output of a successful boot of a TSR II bay controller:

Hardware POST checks NVRAM and boot ROM starts. The green LED turns on and remains on:

BOOTPOST> Starting BOOTPOST> TestFlash Starting...OK BOOTPOST> TestDRAM Starting.........................OK BOOTPOST> Test860 Starting...OK

Hardware POST completes and bootROM continues.

Debug: Ready Transitioning to active mode...Done

The bay controller module is operational. The green LED starts blinking slowly.

Troubleshooting a Bay Controller Module

There are two types of bay controller failures:

• Unrecoverable hardware failures 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 has occurred. In this case, replace the bay controller module.

Troubleshooting Chassis Type

When a bay controller boots up with the latest software, it will output to its console screen a description of the bay controller board and chassis type. The chassis type is determined by the placement of the bay controller backplane Dip switch, which are set during manufacturing. If the Dip switch is not installed correctly, an error message is printed on the console and the bay controller will not properly initialize:

Installing the Bay Controller

The bay controller modules are shipped separately and need to be installed. To avoid damage to the backplane, a detailed inspection of the bay controller module VDHM connector is required each time a module is removed or inserted.

NOTE Do not insert bay controller modules from the SSR into the TSR II, as the modules are of a different length.

PROCEDURE: Use the following steps to install the bay controllers module:

Step 1 Remove the bay controller module from its packaging and static protection bag.

Step 2 Before inserting the bay controller module, remove the VHDM protective cap from the end of the module before use. Set the protective cap aside in a safe place (see Figure A-13).

Figure A-13. Remove VHDM Protective Cap Before Use

A detailed inspection of the VHDM connector on the back of the bay controller module is required prior to insertion. Lay the module gently on a flat surface so you can perform a VHDM connector inspection.

Figure A-14. Place Bay Controller Module on Flat Surface

Step 3 Carefully inspect the VHDM connector for damage such as deformed sockets, holes between socket columns, and deformed guide fins on top and bottom of the socket columns.

.

Figure A-15. Bay Controller Module VHDM Connector

NOTE If the VHDM connector has any signs of damage, DO NOT insert it into a bay. Mark the module as damaged and call TSR-BY-AVICI (877-292-8424) to request an RMA.

Step 4 Look into bay controller slot to ensure bay controller path is free of obstruction; for example, packing materials.

Step 5 Continue installation process. Open the release latches on the bay controller module.

Step 6 Align the bay controller module with the aluminum rails above the baseplate.

Step 7 Slide the bay controller module into the left or right card guides from the front of the bay (see Figure A-16).

Figure A-16. TSR II Bay Controller Installation

Step 8 Engage the latches to seat the connector at the rear of the module firmly in the controller backplane.

If reseating a bay controller module does not resolve successfully, then call TSR-BY-AVICI (877-292-8424).

Cooling Module LEDs

The TSR II cooling system consists of two removable blower assemblies located behind the front air intake assembly at the bottom of the TSR II system. Each blower assembly has two blowers, one in the front and one in the rear.

Each blower assembly has two LEDs located on the faceplate. The LED on the right indicates the status of the rear blower of the assembly. The LED on the left indicates the status of the front blower (see Figure A-17).

Figure A-17. Cooling Assembly LEDs

On power up the LEDs go through the following cycle:

• Blink red initially
  
  
• Steady green shortly thereafter
  
  
• Out when communication is established and blowers are operating under the control of the bay controller
  
  

When power up is complete, the cooling assembly LEDs have the following meaning:

Off	Normal operation or loss of power. The blower is running under the control of the bay controller module.
Red	Failure is detected. Replacement of blower assembly is required.
Green	There has been no communication with the bay controller for 5 or more seconds. The fan is running in autonomous mode. Fan speed is determined by an internal thermistor.

Installing Filler Modules

If you must remove a router or route controller module from the TSR II bay for any length of time, a filler module should be installed in the slot immediately until the replacement router or route controller module is again installed. This is necessary for bay cooling purposes, among other reasons.

PROCEDURE: Use the following steps to install filler modules:

Step 1 Align the module with the card guides. Position the metal tabs of the lock latch release levers under the lip of the filler module.

Step 2 Slide the module all the way into the slot until it is seated firmly in the backplane.

Step 3 Tighten the two lock latches. The filler module lock latch locks into position (see Figure A-18).
