2. Ensure that all internal cables are connected and routed correctly and secured by any cable clips or
ties in the server. Keep cables clear of the hinges and sides of the chassis to avoid interference with
reinstalling the cooling shroud and the server cover. The following illustration shows an example of the
cable routing in the chassis with two backplanes for 16 2.5-inch hard disk drives.
• Route the signal cables
1 through the left inner side of the chassis. The signal cables include the
mini-SAS to mini-SAS signal cables, the front panel cable, the front panel USB cable, the diagnostic
module cable, the SATA signal cable for the optical drive if your server has a slim optical drive
installed, and the cable for the front VGA DB-15 connector.
• If your server has a RAID card and an expander card installed, properly route the mini-SAS to
mini-SAS signal cables
2 that are connected from the RAID card to the expander card.
• Route the backplane power cables 3 through the right inner side of the chassis.
• If your server has a slim optical drive installed, connect the power cable 4 for the optical drive to the
optical drive power connector on the backplane and properly route the cable in the chassis.
