Drive cable routing (upper tray)
Cable routing for drive components is different for SAS and NVMe drives:
Routing
• From: Upper system board in lower compute tray, "PCIe/NVMe" connector (see
"System-board connectors" on page 165)
• To: Drive backplane 1, connector "NVMe" (see "Drive backplane connectors" on
page 173)
• From: Upper system board in lower compute tray, "NVMe" connector (see "System-
board connectors" on page 165)
• To: Drive backplane 2, connector "NVMe" (see "Drive backplane connectors" on
page 173)
• From: Lower system board in lower compute tray, "NVMe" connector (see "System-
board connectors" on page 165)
• To: Drive backplane 3, connector "NVMe" (see "Drive backplane connectors" on
page 173)
