DS25 Problems...

I bought a one CPU DS25 on eBay. Before it was sent to me they removed the 2nd CPU and said they had made no other changes.
When I try to start it up I get
2 1 2 Beeps
1 3 3 Beeps
The first 3 LEDs are lite up, which makes no sense.

I opened the box and everything looks good. The remaining CPU is in slot 0. The 2GB of memory (4 x 512MB) are in memory array 0. There are no options in the PCI slots.

Any ideas

Re: DS25 Problems...

2-1-2 says Configuration error on CPU or system configuration error.

1-3-3 says No Usable memory detected.

L1, L2, L3 lit up means Bad RMC Flash

I just pulled those off the owner's manual.

I'd say check and reseat the memory dimms first.

Re: DS25 Problems...

I have the same manual and I am aware of what the beeps and leds mean.

I reset all the memory before I posed the forum questions.

Any other ideas?

Re: DS25 Problems...

Which model A or B?

Have you tried to access the system through RMC? If nothing works RMC should answer up with just AC plugged in. Check the system using env and status commands in RMC.

Chapter 6:
http://www.compaq.com/alphaserver/download/ek-ds250-ug-d01.pdf

If RMC corruption is suspect, then check the system modules jumpers and switches to make sure they match the correct system configuration for the CPU installed per the service guide. You may have to reflash the system from Fail-safe mode.

Re: DS25 Problems...

I've not tried to run an AlphaServer DS25 with one CPU.

And with what the occasional misadventures that can arise with eBay and with shipping and with the removal of the CPU, the operational pedigree of the hardware here is somewhat questionable.

Burn a current AlphaServer firmware CD-ROM.

Use the failsafe loader (FSL, or sometimes Failsafe Boot FSB) to re-flash the system, and to also reset the RMC to factory.

Details of both are in the AlphaServer DS25 User's Guide.

Re: DS25 Problems...

I have changed the FSB jumper and got the same response - nothing at the console still.

>I have changed the FSB jumper and got the same response - nothing at the console still.

To confirm the "nothing" here and the status, you're on the COM1 serial line, you've reset the RMC to factory, and you've tried to reload the firmware using the FSL, and you've (still) received a fault indication?

If so and then based on your other comments around re-seating all modules, etc, then I think the box is busted. Or it considers itself busted, due to the removal of the CPU.

Re: DS25 Problems...

Have you tried connecting a serial terminal to the *modem* (bottom or left 9-pin rs-232 depending on system orientation) port (9600,8,N) and issuing the RMC sequence per the manual?


^[^[ rmc

This *should* get a response as long as AC is plugged in.

Hope this helps.

Re: DS25 Problems...

You've mentioned that you get no console response, but have you actually tried to get to the RMC? Press ctrl-[ ctrl-[ RMC (to get the RMC prompt.)

Re: DS25 Problems...

Just to refresh evryones memory as to what I have tried:

System gives series of beeps. No response at console.

1) System down. Poser on. Connect serial terminal (Reflections - I have used it as a console on other computers)(null-modem) to port 1. clrl[ ctrl[ RMC gives me no response from computer. I have not set RMC switches to default.

2) Changed FSB jummper J25 to 2 & 3. System gave me same beep errors as before. No response at console terminal.

3) Tried other memory - as before.

Any other ideas?

Looks to be firmly DOA. Call the seller?

Re: DS25 Problems...

More ideas...

Verify 20-01EBA-09 512MB dimms are installed.

Verify Clock and TIG switch settings.

Clear RMC via J66.

Try to access RMC from the other port.

Install J68 1-2 to direct all traffic through the RMC, move the console cable and then issue the rmc escape sequence ^[^[rmc

-or-

Change J46 to load TIG from SROM.

From the Service Manual:

3.5 Forcing a Fail-Safe Load
The fail-safe booter (FSB) is another variant of the SRM console. The
FSB provides an emergency recovery mechanism if the firmware image
contained in flash memory becomes corrupted. You can run the FSB
and boot another image from a CD-ROM or network that is capable of
reprogramming the flash ROM.
Use the FSB when one of the following failures at power-up prohibits you from
getting to the console program:
â ¢ Firmware image in flash memory corrupted
â ¢ Power failure or accidental power-down during a firmware upgrade
â ¢ Error in the nonvolatile RAM (NVRAM) file
â ¢ Incorrect environment variable setting
â ¢ Driver error
3.5.1 Starting the FSB Automatically
If the firmware image is unavailable when the system is powered on or reset,
the FSB runs automatically.
1. Reset the system to restart the FSB. The FSB loads from the flash.
2. Update the firmware as described in Chapter 7.
3.5.2 Starting the FSB Manually
1. Power the system off, unplug the power supplies, and remove the cover.
2. Remove CPU0 to gain access to J25 jumper on the system board. See
Chapter 8.
3. Move jumper from pins 1-2 to 2-3 on J25.
4. Reconnect CPU0.
5. Reconnect the power supplies and reinstall the system cover. Power up the
system to the FSB console.

3.6 Updating the RMC
Under certain circumstances, the RMC will not function. If the
problem is caused by corrupted RMC flash ROM, you need to update
RMC firmware.
The RMC will not function if:
â ¢ No AC power is provided to any of the power supplies.
â ¢ DPR does not pass its self-test (DPR is corrupted).
â ¢ RMC flash ROM is corrupted, but the system will still power-up.
If the RMC is not working, the control panel displays the following message:
Bad RMC flash
The SRM console also sends a message to the terminal screen:
*** Error - RMC detected power up error - RMC Flash corrupted ***
******************************************
NOTE: If the RMC is corrupt, you may not get an output from COM1. If this
occurs, remove J68 and move the serial line to the COM2 port.
******************************************
You can update the remote management console firmware from flash ROM
using the LFU.
1. Load the update medium.
2. At the UPD> prompt, exit from the update utility, and answer y to the
manual update prompt. Enter update RMC to update the firmware.
UPD> exit
Do you want to do a manual update [y/(n)] y

After updating the RMC you should regain console functionality and can update the remainder of the system f/w using the manual update procedures.

fwiw:

This *WILL* work if your emulation software is mapped and passing the correct escape sequence to the port. Otherwise, suggest using a direct attached VT serial terminal to the port(s) mentioned above if the console port is not producing output.


LED 1 LED 2 LED 3 LED 4 Power-Up Message
ON ON ON Off Bad RMC flash [ 1 ]

Note 1: If the RMC flash is bad the system will still come up, however the bad RMC flash LED will remain lit until a new RMC flash image is loaded. RMC will not have full functionality, use COM2 or VGA display to flash the RMC.



-or-

Just replace the system and cpu modules ;-)

Please don't think I am ignoring your responses. I will be out of town and will look at this again next Tuesday.

I have decided to close this thread and award points. The problem was not solved and I am sending it back.
