• A single PCIe3 2x4 NVMe M.2 internal carrier adapter can be installed in the internal PCIe3 x8 slot (P1-
C49) in supported systems. It can also be installed in the other internal PCIe3 x8 slot (P1-C50) if the
PCIe3 x8 SAS RAID internal adapter 6 Gb (FC EJ1C) is installed in slot P1-C49.
• Up to two PCIe 2x4 NVMe M.2 internal carrier adapters (FC EC59) with two NVMe M.2 Flash modules
(FC ES14) each can be installed in supported systems.
Important: Ensure that the 01GY502 SAS divider is re-installed and the 01GY494 SAS slot air block is in
place if you're replacing the FC EC59 in slot P1-C49. f you're adding a second FC EC59 in slot P1-C50, the
01GY502 SAS divider and 01GY494 SAS slot air block must be removed.
