The 2nd LED (on left hand side, #) is blinking while the LED (on right hand
side, O) is not ON at all. The PHY port 1 and PHY port 6 is not blinking.
It sounds like the primitive loader is running. When a module
is powered up/reset core diags are executed. This a couple of
tests that make sure the CPU and DRAM are behaving themselves.
If they are, the CRC on main flash is checked. Main diagnostics
and the operational firmware are stored in main flash. If the
CRC on main flash is incorrect, the primitive loader is executed.
The primitive loader has only one job: load and blast into flash
a new firmware image. The primitive loader blinks the # LED every
time it receives a message from the MAM (via the backplane).
This is about once per second.
When I use DOWNLOAD SHOW DEVICE 1.2.3.4 /force=chasdescr/mod=6
I get DECcon 900MX, 6 port FDDI Conc, HW=v1, RO=v1.1, SW=unknown.
Since the primitive loader is running, there isn't a
firmware version to report. This is the reason for
the "SW=unknown."
Any idea how can I upgrade to DEF6X200.BIN (version 2.0)?
Issue the NDU command again. It will take about 9 minutes
for the upgrade to complete when going thru the HUB. About
4 minutes to get the image into the HUB's landing pad and
4 minutes to get the image from the HUB's landing pad to the
concentrator's landing pad. During this time the concentrator
is still acting as a concentrator, except when the primitive
loader is running (as in this case).
Following is upgraded that I have done:
1) Set up DH900 with IBM address on slot 3 which is a DECrepeater900TM.
2) Insert DC900MX into slot 6.
3) On VMS system, use NDUplus to download the DEF6X200.BIN.
HUB_LOAD.COM (1008.10) with ip address of DH900 (IBM Ip address),1.2.3.4
comm=public, file=mom$load:DEF6X200.BIN, slot=6.
4) Then NDU prompt with the correct load file, transferred completed and
lastly, it returns the HW=v1, RO=v1.1, SW=v1.0.0 ----> this may be the
problem (Since it is same before the upgrade).
This is ok. The reason for this is that NDU reads the
concentrator's sys descriptor before it has blasted the new
firmware image.
5) Then remove the DC900MX from DH900, plug again, I got abnormal
LED display as stated above.
If you removed the concentrator from the HUB while it was blasting
the new image, the CRC for main flash will be invalid.
This will cause the primitive loader to be entered on the next
reset/powerup.
I can do the upgrade for DB900MX with HUB_LOAD (but I use another IP
address for DB900MX other than the one for DH900's IBM ip address, and it
works.
So I just wonder how it works with DC900MX?
The concentrator and the bridge should upgrade in the same
way.
Try the upgrade again and let me know the results.
