Cable Routing
The RAID controller connectors in this server are shown in Figure C-2. The colored lines indicate the
recommended cable-routing paths from the backplane to the possible controller locations:
• The red line is the cable path to a controller in PCIe riser 1. This is the only riser available in
single-CPU configurations.
• The blue line is the cable path to a controller in PCIe riser 2.
• The green line is the cable path to the embedded RAID connectors on the motherboard.
