b.
Push the tabs into the slots and push the air divider downward to secure it
against the wall.
To ensure proper alignment of the Fault Remind switch, both tabs must be engaged with
their slots.
28.
Ensure the SAS/SATA cables are routed through the slot in the air divider.
The back side of the divider has enough room to house the cables if they are flat and side-by-
side. Do not allow the cables to interfere with the Fault Remind button mechanism.
29.
Connect the SAS/SATA cables to the disk drive backplane.
The mini-SAS plug that terminates the short SAS/SATA cable must be inserted into the upper
mini-SAS connector on the disk backplane. This short cable connects the SATA DVD to its
USB-SATA bridge on the motherboard. The longer SAS/SATA cable connects drive bays 4
and 5 to a storage device in the back of the system. The lower mini-SAS connector on the disk
backplane requires the standard, four-channel mini-SAS cable for drive bays 0 to 3.
30.
Install all memory risers.
See “Install a Memory Riser Card” on page 138 .
31.
For a two-CPU system, install the air baffle, ensuring that the foot on the front of
the baffle is under the fan board ribbon cable.
32.
Install all PCIe cards.
See “Install a PCIe Card” on page 151 .
Note -
During the process of reinstallation of the HBA card, it might be easier to reconnect the
SAS/SATA cables before installing the card in its PCIe slot.
33. Install the power supplies. See “Install a Power Supply” on page 125 .
34. Prepare the server for operation. See “Prepare the Server for
Operation” on page 227 .
