Cable
Routing
1 Power to drive
backplanes 1, 2, and 3
• From: Storage interposer (see “Storage interposer connectors” on page 107)
– For drive backplane 1, use interposer “BP 1/6” connector
– For drive backplane 2, use interposer “BP 2/5” connector
– For drive backplane 3, use interposer “BP 3/4” connector
• To: Drive backplane, “Power” connector (see “Drive backplane connectors” on page
109)
2 RAID flash power
module
• From: RAID flash power module connector
• To: RAID card, flash power module (J14) connector (see “RAID card connectors” on
page 108)
3 Drive power
• From: Lower compute system board in lower compute tray, “POWER” connector
(see “System-board connectors” on page 103)
• To: Storage interposer, “POWER” connector (see “Storage interposer connectors” on
page 107)
4 Drive signal
• From: Lower compute system board in lower compute tray, “Signal” connector (see
“System-board connectors” on page 103)
• To: Storage interposer, “SIDEBAND” connector (see “Storage interposer connectors”
