Servicing PCIe Cards and the Dual PCIe Card Carriers (DPCCs)
Storage Drive Population Rules
When populating the storage drive slots, use the following rules:
1. Every slot in the storage drive bay must contain either a storage drive or a drive filler panel.
2. Sort disks by capacity and technology (HDD vs SSD) and install in this order:
a. Install the HDDs first, starting with the smallest capacity in the drive slots in ascending
slot order (0, 1, etc.).
b. Install larger HDDs in increasing capacity and into storage slots increasing in number.
c. Install SSDs into remaining storage slots increasing in number.
Servicing PCIe Cards and the Dual PCIe Card Carriers
(DPCCs)
The server PCIe cards are housed in pairs inside card carriers called DPCCs (dual PCIe card
carriers). The DPCCs allow the cards to be hot serviced (removed and installed while the server
is powered on).

Remove a DPCC
This component is accessed directly from the rear of the server. Dual PCIe Card Carriers
(DPCCs) can house two PCIe cards. You need to perform this procedure to replace or to remove
and install a PCIe card.
