Cable
Routing
1 Drive backplane 1 NVMe
• From: Upper system board in lower compute tray, “PCIe/NVMe” connector (see
“System-board connectors” on page 283)
• To: Drive backplane 1, connector “NVMe” (see “Drive backplane connectors” on
page 291)
2 Drive backplane 2 NVMe
• From: Upper system board in lower compute tray, “NVMe” connector (see “System-
board connectors” on page 283)
• To: Drive backplane 2, connector “NVMe” (see “Drive backplane connectors” on
page 291)
3 Drive backplane 3 NVMe
• From: Lower system board in lower compute tray, “NVMe” connector (see “System-
board connectors” on page 283)
