Hi guys. I have an old Netra T1 that I'm hoping to recover here so I can twiddle around with Solaris 10.
It's been unable to power on despite issuing the "poweron" command or hitting the switch at the back of the server for some time. The LOM command "env" reports ALARM3 ON and everything else OK.
So just today, I decided what the heck I don't really care anymore and took the PSU out took it apart. During the process I got a nasty shock and tripped the entire house as I forgot to unplug the mains. So that's 240volts my friend, don't try this at home. I swear I won't do this again.
Anyhow, I figured that the switch at the rear of the PSU box goes to the service processor connector, so ultimately the motherboard is still responsible for keeping the server powered on.
I decided to make a workaround, so I cut the white cable (power-on) of the ATX connector and permanently soldered it to the outer case (ground) and wolah, the server now powers on, but this is all I get:
And it stops right there. I don't even get the usual POST message with the CPU and RAM info, etc. If I hit "#.", I go back to the LOM prompt. "env" command shows everything OK. I tried altering bootmode, but it goes back to "normal" once I disconnect/reconnect the power (since I have permanently soldered the power-on ATX line, the box is always powered on when a power cord is connected, so the only way to reboot the machine is to pull the plug)
Anybody has any idea what's wrong? Or is my board really dead?
I guessed wrong. My colleague had came across this problem before and infd that it was due to loose power cord(something like that). In the end, replaced the PSU. Then the system has been working fine since
I have a PSU shipping from USA to SG right now that I bought off eBay. However that PSU has the same manufacturer model but the connector looks wrong. I will have to figure out how to attach the current connector when it arrives.
Meanwhile, the PSU actually powers up fine with my manual bypass. I have a voltmeter and it reads the voltage correctly. I am worried it might be a dead board and I end up wasting $ on a PSU since the 'poweron' function is just an electronic switch within the board.
Do you have any idea what ALARM3 actually means? From what I know thats a user programmable alarm, but I don't see any logs or anything indicating a bad PSU.
Hi Guys,
