Hi All

This is my first post on the Overclockers forums despite having used this place as a rich source of solid information for quite a while now!

But I felt my problem had become so unique to the situation that it warranted the registration and this post, so please bear with me as I try to explain the nature of this 'chassis - motherboard incompatibility'...

I've been tasked with building a home server by a friend, who provided me with all the parts to 'put together' (and won't budge on them). On the surface of it it seemed simple enough, especially with the plethora of info on the net about home server building.

However, it soon dawned on me that the motherboard I'd been given was not a dedicated 'server type', but rather an AMD AM3+ board [Asus M5A88-V EVO] (along with compatible cpu & memory). This wouldn't normally post too much difficulty except that the chosen chassis was a rackmount case: Chenbro RM21400

The problem is that the front panel I/O connections have 'LAN 1 SP' and 'LAN 2 SP" cables (for front two LAN LED activity), which appear to have no place to connect on the motherboard's 'system panel connector' -nor anywhere else on the board. :confused:

I saw NathanE's excellent "Rackmount server build incl. Asus P6T7 mobo" post in these forums, which is a similar build - but gave no explanation about how he got around the problem of the LAN 1 & LAN 2 front panel LED activity. So this would be my question to NathanE:

How did you get around the problem of attaching your chenbro LAN 1 & LAN 2 front panel cables to your P6T7 mobo? The P6T7's system panel connector also doesn't carry such connections, so where if it all did you put them in order to have the front panel LED LAN activity function?

Admittedly, this is my first attempt at server building (only ever having constructed air & water cooled pcs before); I'm concerned that in the absence of dedicated connections there may be some warranty-voiding soldering involved!

[I checked with Asus: they have a pretty comprehensive list of all the chenbro chassis that their mobos are compatible with. The only single socket AMD CPU chenbro-compatible board listed is the M2N-LR, which is a far cry from the components already in my possession! (But according to that board's spec, it does indeed have '2 front lan leds' among its onboard I/O connectors..!)]

I greatly appreciate anyone here imparting their pearls of wisdom to help a relative noob get over this hurdle!

Thanks
 
It is not a compatability problem as such just that unless you are using a server or specially designed m/board you would not normally get lan leds. Basically you just will not connect them and they will not work.
 
Ok, thanks for clearing that up!

On a side note, the front panel connectors appear to be short of speaker sound cables; I suppose that means I won't get any system beeps with this config then either..?
 
Front panel speaker/headphone & mic sockets have nothing to do with BIOS beeps.

Some boards have a built in piezo speaker, rest have a 2 pin header to plug a piezo speaker into - some supply this too, if not a "Mini PC motherboard Speaker, New, UK" can be had for a couple of quid.
 
I see, well it's reassuring to know I'll get those bios beeps

I'm remain curious, however, to know if there's any way to get the LAN 1 & 2 leds to work, by soldering the Lan 1 & 2 SP cables to the appropriate part of the motherboard, for example..? Is there any resource I might use to guide me through such a warranty-voiding minefield?
 
I saw your trust e-mail but didn't get a chance to reply.

Basically, I didn't bother with the LAN LEDs. They're pretty pointless in this day and age really.

I'd not even consider soldering anything either. Just forget about the LAN LEDs and worry about something more important!

Most consumer motherboards, even high end ones, don't have LAN LED outputs.
 
Thanks for the response & sound advice! I take your point about focussing on other more important issues; I was merely considering the leds to try to utilise the functionality of the chassis to its fullest extent for my 'client' (friend in need). But I guess I'll do without the lights in this case...
 
hmmm, dunno why a thumb-down icon has appeared in my last post - please ignore it!
 
A lot of NIC chipsets are integrated into the southbridge these days, and don't even have a pinout for an Activity LED.

You have to go upmarket to server mobos to get the pinout, let alone an actual header on the mobo!

Mmmmmmm whilst not disagreeing with you here

I just checked round the back of both my rigs and both have LED activity indicators flashing away like mad on the LAN connections on the I/O panel

Agree however about if you have not got any connectors for front panel... roll up, tape them up and shove away somewhere

:)

Ive never seen a NIC which does not have lights at the port. Ive never seen a board which has separate connectors for LAN LEDS.
