T5500
Hello all.
Always loved this community. Was hoping for a little guidance. Just started as a tech a couple months ago after being a computer junkie my whole life. My boss gave me a T5500 to use for various stuff. I’ve been playing around a lot with it.
Couple questions: Inside was a two wire cable connected to the mobo labeled AUX_LED and not connected to anything else. I would guess it would connect to the front led panel but that’s managed by a like 20 pin connector that has several light and what not. Is it for the riser card for a second cpu?
I have a riser card on the way. It has 3 memory slots on it. When I got it it had 3x 4gb. I want to get 6x 4gb more and have 36gb but looking in the manual for it if you have the mobo filled with 4gb the riser card has to have 3x 8GB. Any ideas?
Anyone know if the eSATA port on the back is 12v? From pictures it doesn’t look like it but I would guess from a powerhouse of a tower it might.
Thanks for any advice or input.
I LOVE MY 50 POUND BEAST!!!

Hi @Linksys to the past ,
It's for add-on RAID card. For example, if you got a PERC H310, there would be a "SAS ACT LED" port on it:
Then you can connect it with the mobo's AUX_LED port by a Dell LED Light Cable MJVMK:
Check out page #2 of the Service Manual. It shows how to populate memory with riser. Noted that memory MUST be populated as the recommended sequence and size or you system may not boot.
Generic 5V eSATA port like this:
While a 12V eSATA port, known as eSATAp, like this:
Therefore the one on T5500 should be a generic 5V one.

Thank you so much for your help. It was bugging me that I couldn't find anything about it. What's curious is that the little cable I have has the same 4 pin connector on both sides. I wonder what card was attached to it. While I have you I was hoping I could ask a couple more questions.
Can you add a hard drive attached with eSATA to a raid, probably going to be SHR?
I found a port on the motherboard called LPC_DEBUG. Is that only for Dell debugging or is there a client side use for this?
Is there an easy way to calculate if you are close to over loading the PSU?
I have a 875w and will have:

Hi again @Linksys to the past ,
No need to wonder if you pay attention to the hints of H310 and make a search really. It's not difficult to locate kinds of RAID card using the 4-pin black connector, just like this:
Again, simply google "Dell T5500 RAID max drive" leads me to the following link:
The number of hard drives and which RAID configurations are supported on Precision Desktop Workstations
Therefore, it would be a no for adding eSATA drive to T5500 onboard RAID.
And for SHR, if you're talking about Synology Hybrid RAID, don't thinking about it. It's a custom designed technology and would only works on their products.
Googled again for 5 minutes and already found a long description in Wiki and a video in Youtube telling what LPC stand for and what's the usage. Maybe you can find the answer as well.
Lots of power supply calculators available on the net, like the one from CoolerMaster. Of course it's just an estimation. If you need an accurate meter, you may need a setup as what Tom's Hardware did.
