Hello CY7N1 is a cable to connect to a 4HDD backplane. The 8HDD backplane cable is DJXF7. Thanks
I have a T320 with the 8x3.5 hot-swappable backplane for SAS drives. I ordered a Perc H710 (p/n 342-4203) to replace the H310. The existing SAS cable has the wrong connectors for the H710. I chatted with Dell this morning and they told me that I needed Dell Part# cy7n1. I ordered this. However, after ordering I searched online and the pictures seem to show a cable with only a single connector at each end. What is the correct cable that I need? Thanks.
