Step 3: Power PC/Server Off and Discoennect Power Cable
Remove the mounting screw and existing bracket from the
rear panel behind the selected PCIe 4.0 slot. Align the
gold-fingered edge on the card with the selected PCIe 4.0
slot. Press down gently but firmly to ensure that the card is
properly seated in the slot. Then, screw the bracket into the
computer chassis.
Step 4: Install the RAID Adapters
Step 2: Mount the M.2 NVMe SSD
(1) Remove four screws that secure unit’s front panel
(2) Gently insert the SSD into slot, meawhile put the screw
into the groove
Step 5: Install SAS/SATA Connection Cable (Optional)
The ARC-1886-6N2I utilizes the optional CBM module to
provide below function:
(1). Support Off module (PLP) hold-up power, eliminating the
need for capacitors on the NVMe SSDs which helps reduce
cost.
(2). Support M.2 slot fault LED status and easily be identified
as a failed drive when it is removed from the system PCIe
slot.
(3). Support power to the 8GB cache if it contains data not
yet written to the drives when power is lost.
Please refer to Appendix B of the user manual for installing
the cache backup module (CBM) in your ARC-1886 RAID
adapter.
Step 7: Adding a CBM Backup Module (Optional)
Step 6: Connect Monitor Port - LAN Port
User can remote manage the RAID adapter without adding
any user specific software (platform independent) via
standard web browsers directly connected to the RJ45 LAN
port.
The ARC-1886-6N2I can use two SAS/SATA ports to support
secondary array module.
Below is an example using the space and connections inside
the 2019 Mac Pro next to the PCIe card slots to install and
connect ARC-CD2I up to two SAS/SATA drives in the 2019
Mac Pro.
(3) Fasten the screw to secure SSD
(4) Repeat steps 2 to 3 to install the remaining SSDs
(5) Refasten four screws to secure unit’s front panel
