PERC H755 Cable Kit?

Question

We are looking on installing a PERC H755 PCI-E (405-AAXT) in our r750. However the PERC card doesn't come with the SAS cable. Does anyone know the cable required (part code) to connect the H755 to the backplane?

SAS cable can vary based on the backplane you have on the server. Can you share the backplane you have on R750. You can also refer below link and share which Figure represent your config

Kindly advise what cable is required to add PERC H755 Front Raid controller to the Dell R550 Server . The server has a 8x2.5"back plane.

The PERC cards are not coming with cables

Back Plane Side Cable is SL9 _PCH_SA1 and the connector on the PERC H755 FRONT card is CTRL_DST_PA1

Thanks & Regards,

Jacob

Hello, may be the following part code. But unfortunately I can't be 100% sure. Because I cannot check whether there are different parts for different BP variations through a more detailed document. However, when I examined the cables for the R550, I thought this might happen. Please note that this changes the PERC and it's recommended to get in touch with your local sales team or a team dedicated to those who wish to purchase part components. They can provide the most accurate information based on your specific configuration and requirements.

We want to add below RAID controller ( internal drives) to the server

The H755 Front card PN : 405-AAXO PERC H755 SAS FRONT

The Server is coming with 8x 2.5"SAS/SATA HDD backplane

Please see if you can help us with the right PN for the cable

DELL-Erman O · Answer

I don't have the sourcebook for R550 but when I review it I believe the part is below cable. Before purchasing please consult Dell sales team. Because as a technician team member I can see the parts in spare part system. I don't have access to sales team system. Also lets see how to community contribute the thread.

Thanks for suggesting the PN

Before we order we want to confirm on the below

I have gone through the service manual and found that the cable required is for connectivity from the PERC 755 FRONT card to slot 18 of the system board connector

and the cable required is the one connecting from

From CTRL_DST_PA1 (Signal connector on the front PERC H755) to SL3_CPU1_PB2 (Signal connector 18 on system board)

Section Figure 1. 8 x 2.5-inch SAS/SATA

Please see if it is possible to confirm the cable Part #:HVNP8 suggested is the same

We also want the TRAY for installing the H755 Front card within the server like in the below picture

@JohnPJ​ Hi John, do you have the sku o part numbers of the cables? Or if theres a cable Kit with all of them? So hard to find something so simple. Dell doesnt say anything on the datasheet or specs. TIA!
