ReadyNAS Pro 6 won't turn on
Hi community gurus,
I figure this might be a long-shot, but it's worth a last-ditch effort. I recently went to turn on my NAS and found no response. Pressing the power button has no effect. There's no solid link lights on the NICs, so my usual method of WoL wasn't going to succeed.
The unit is usually off, always shutdown in a proper manner. If the device is dead, so be it, but obviously having no access to the data that resides on it is a little concerning.
The symptoms closely mirror those reported in this thread: https://community.netgear.com/t5/New-ReadyNAS-Users-General/ReadyNAS-Pro-6-won-t-start-up/m-p/1802079#M38025
There are random erratic blinks from the NICs, but that's about it. Every connector has been re-seated, the RAM has been re-seated, the BIOS battery replaced. Praying to the NAS Gods while hopelessly pressing the power button produces nothing, not even a sausage.
I have a couple of what I thought were ATX PSUs, but the 24 pin connector doesn't completely match - wire colours and individual pin shape are slightly off.
I thought I'd try testing the PSU by jumping the green enable cable to ground. The PSU turned on. I repeated the process with everything connected, fans started, disks spun up, LCD sprang to life with "ReadyNAS", but that's about it. There's no apparent boot progress, no change to the LCD display. Pressing the boot button initially gave me a boot menu, in which I selected "Normal Boot", which didn't get me far. Subsequent presses of the boot button failed to evoke a boot menu. I measured the various PSU rails, and they all appeared to produce a reasonable value.
Maybe it's an issue with a specific rail on the PSU, but it's difficult to test/confirm. If there's anything else that someone might be able to suggest, I'd be grateful. I'm not quite ready to start the grieving process for the loss of 25 years of data.
For what it's worth, the device was/is running OS6.

This does sound like a power supply issue, and that's the most common failure of that model. A standard ATX12V supply works just fine when connected externally, and that's the best way to see if the PSU is the problem. Testing a power supply without a load is really not a very good test. It could give you insight, but may also make you think the supply is fine when it's not.
The supply is a standard SFX format one, but has a longer 24-pin cable and more 4-pin MOLEX than most. While it's rated at 300W, the 12V rail is more akin to most 400W ones. While I used to recommend you buy a400W or larger SFX supply and cable adapters, there is a seller on eBay that has some that already have the right cables and they've lowered the price to where that's now my recommendation.
Thanks Sandshark. I'm currently seeking a suitable test PSU to verify if it is a power rail issue - just have to find one with a 24pin connector. Tests of the stock PSU were performed both with and without load. The PSU line of enquiry is the best lead so far.
Ever since the VPD corrupted itself a few years ago, this system has left me waiting for the other shoe to drop. There's always the question of "Will it boot this time?".
