Cable
Routing
1 Drive backplane 1 NVMe
• From: Upper compute system board in lower compute tray, “PCIe/NVMe” connector
(see “System-board connectors” on page 103)
• To: Drive backplane 1, connector “NVMe” (see “Drive backplane connectors” on
page 109)
2 Drive backplane 2 NVMe
• From: Upper compute system board in lower compute tray, “NVMe” connector (see
“System-board connectors” on page 103)
• To: Drive backplane 2, connector “NVMe” (see “Drive backplane connectors” on
page 109)
3 Drive backplane 3 NVMe
• From: Lower compute system board in lower compute tray, “NVMe” connector (see
“System-board connectors” on page 103)
• To: Drive backplane 3, connector “NVMe” (see “Drive backplane connectors” on
page 109)
