Connecting standard data cables
External hard drives installed in HP Z400 and HP Z420 Workstations do not have cabling preinstalled
on the system board. To connect the RAID controller card cabling for these configurations:
1. If connecting a SAS hard drive, ensure that there is a SAS-to-SATA adapter or SAS-to-SATA cable
(included with the HP workstation SAS hard drive kit) attached to the data connector on the SAS
hard drive. Figure 5 Attaching the SAS-to-SATA adapter or SAS-to-SATA cable on page 7
shows examples of adapter types A and B.

For adapter types A and B, select the required data cable for the workstation from those shipped
with the hard drive.

Cabling with adapter installed
Use straight connector to straight connector data cable. Plug the end of the
data cable into port 0 of the RAID controller card; and plug in opposite end
of the data cable into the adapter.
Plug in portion (2) of the SAS-to-SATA cable into the hard drive; plug in
portion (1) of the SAS-to-SATA cable into port 0 on the RAID controller card;
plug in portion (3) of the SAS-to-SATA cable into SATA power source from
the power supply, as shown in Figure 6 Attaching the data cable
on page 8.
