RAID Controller Cabling

This section includes the following topics:

•Cable Routing, page C-18

•Cisco UCS C22 Server Cabling, page C-19

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.
