"tim.yoshi" has one, but no time
I'm still more interested in connecting cheap PCI-e x1 slot gigabit LAN card to mezzanine slot. But that requires mezz-MXM adapter, which is somehow pricey. But once traced, then the gigabit LAN for blade will be cheap as 10€ for mentioned NIC. Effort to connect it should be similar to connecting pass-through ethernet module. Maybe even straigtforward, if pass-t module will require OA to work...
Hi Chris0709
I had one LOT OF 2 HP QMH2562 8GB PCIe Dual Port Fiber Channel HBA 455869-001 451871-B21 | eBay mezzanine card and with a hot blower, I took it off the board.
I have four bl490c g6 and tested them.

Hi! Could you possibly please give us more detailed instruction, or schematics, or pinout?)
Hi, did you connect pci REFCLK+ / REFCLK- ? or these signals are not mandatory ?
I try to do same thing with a m3 cisco blade, but i don't know how to find these signals.

Hi, no pci REFCLK+ / REFCLK signals are very important, without them the pci card will not be initialized(in my docs CLK+ and CLK-),when the server switches off the resistance of these lines about 60 ohms.
Ok, I have found the 16 data lines, resistance is about 125 ohms, but not yet the clk, maybe no static resistor connected ?.
I ignore for now the polarity for signal pairs and signal id (0..15). I will try different combinations. Hope will destroy nothing..

I have done tests on unconnected mezzanine board, maybe if connected to motherboard I will mesure 60 ohms somewhere.
i believe c to refers to “connect to” on the pcie adapter / card ur hoping to connect.
the Diagram is a literal display of the socket on the main board, the black areas are GND. The columns connected are 2,3,5,7,9,10,12,13,15,16
the rows are 1-9 so either 1,3,5,7,9 or 9,7,5,3,1 are gnd leaving rows 2,4,6,8 for connection to relevant points.
Mirror this for other side connector.
Only part I’m struggling with is the top part, the layout is odd, I presume it’s offset going down. But until I find one to unsolder and probe ( I’m currently researching how to find the relevant pins on the pcie side, any help and advise be gratefully recieved, if there’s a diagram of the pinout for the connector you used Warwick that’s be super helpful. Thx
Hello guys,
I'm sorry to reopen a (not so) old ticket!
Did someone manage to start a bl460c gen9 outside the chassis?
I tried combination of dipswitch from older blade gen without success.
I found 2 different behaviors with switch 8 and 12:
-8: the led near the sd card slot keep flashing (when with other switch light up then go dark)
-12: the blade draws ~250ma instead of ~180ma
I tried letting them start for a long time, but I get no light on the front panel.
I have 3 of these blade, with very nice spec, but I find the c3000 chassis a little bit pricey, and when I found cheap c7000, shipping is killing it.
Best regards!
Rémi
