Riser cards
Use this section to understand the cable routing for riser cards.
The server supports up to three riser cards: riser card 1, riser card 2, and riser card 3. Among which, only
riser card 3 needs cable connections:
•
“Riser card 3 power and sideband connection” on page 64
• “Riser card 3 (x8/x8 or x16/x16 PCIe) cable connection” on page 65
The riser card types vary by server model. For detailed information, see “Rear view” on page 39.
