HP Z620 floppy header

HP Recommended
HP Z620
Microsoft Windows 7 (64-bit)

Hello Forum,

according to the "HP Z220 SFF, Z220 CMT, Z420, Z620 and Z820 Workstations - Maintenance and Service Guide", page 176, the HP Z620 should have a header P10 (named "FLOPPY" on the board). For the life of it I am unable to find that header on the Z620 motherboard.

 

I am not planning to install a floppy drive, but require a floppy power header to connect a SATA DOM to one of the internal SATA ports of the workstation. The SATA DOM requires 5V power and uses a floppy connector type to source that voltage from the motherboard.

 

I would appreciate if somebody could point me to the location of that hidden P10 header on the board.

 

Thanks and regards,

 

Atom2

power for the floppy drive and SATA power, is taken from the power supply, not the motherboard

 

 

 

 

 

 most SATA based DOM's do not use a floppy connector for power, unless you have a  custom made OEM type DOM like this supermicro DOM

 

https://www.supermicro.com/products/nfo/SATADOM.cfm

 

and most custom OEM DOM's that do not use normal sata connections will usually use a 2 pin connector for power

most newer 16GB and larger dom data/power connectors look like this look like this:

connect your sata Disk On Module onto the power supply's sata Power or floppy connector and the SATA data cable to the DOM and the motherboards sata port

DGroves,

thanks for your reply. I do, however, wonder whether we are talking about the same motherboard. You are referring to an IDE port, but as far as I am aware of, the HP Z620 does not have any IDE ports - it is a SATA/SAS only system and actually lacks IDE connectors.

 

In terms of SATA DOMs, I do have a custome OEM SATA DOM sized at 1GB which is a left over from a NAS system which is no longer running with the original firmware but has rather been installed with FreeNAS using two USB sticks with 16GB each (mirrored). The SATA DOM I want to use uses a standard SATA connector as found on the motherboard, but requires power to operate and that is sourced through a floppy power connector, a so called "Berg connector" - see https://en.wikipedia.org/wiki/Berg_connector.

 

My SATA DOM looks similar to the right hand side one in your link from SuperMicro - although it is differently shaped and from a different company, but the connector is identical. It, however, only uses the 5V source from the floppy header (which also sources 12V) and therefore uses 2 pins of the 4 pin header only.

 

I was actually expecting to have the correponding header for that connector somewhere on the motherboard. So in essence, I am still searching for that header ...

 

The 1GB size is also plenty for what I want to use it for: The plan is to just use it to host the Clover bootloader in order to be able to install Windows 7 x64 on a HP Z Turbo Drive G2 which uses the NVME protocol not natively supported on the HP Z620. Clover would be able to circumvent that by starting a UEFI shell and then inserting an UEFI module to be able to access and boot from the NVMe SSD on the HP Z Turbo Drive G2

my mistake i referenced the z600 not the z620, you are correct that the z620 only has sata ports

 

(i have edited the first post to correct this)

 

however the rest of  the information is correct, you will need to take the 5/12 volts from the power supply's SATA connectors

 

you can get SATA to floppy adapters from ebay/amazon/new egg
