OpenFlex™ Data24 4000 Series

1. Install the Rear of the Rail Assembly

Action: Install the rear of the rail assembly into the server rack.

Details:

• Insert the rear pins of the rail into the rear vertical rack rail. Ensure correct orientation as rails are right/left specific.
• Use a T15 Torx screwdriver to install two washers and screws to secure the rear of the rail to the rear vertical rail mount.
• Repeat for the second rail.

Important Note: Always install rack-mounted equipment in the lowest available U-height to keep the rack's center of gravity low and reduce the risk of tipping. ⚠️

2. Install the Front of the Rail Assembly

Action: Install the front of the rail assembly.

Details:

• Insert the front pins of the rail into the front vertical rack rail.
• Use a T15 Torx screwdriver to install two washers and screws through the top and bottom holes on the front vertical rail mount.
• Repeat for the second rail.
• Verify the rails are level from front to back and side to side.

Note: The front vertical rails have four holes for mounting the enclosure. Use holes 1 and 4 (top and bottom) for mounting the rails. Holes 2 and 3 are reserved for the enclosure's captive screws (step 3).

3. Install the Enclosure into the Rack

Action: Install the enclosure into the rack.

Details:

• Using lift equipment or assistance, lift the enclosure and set it on the rails.
• Slide the enclosure into the rack until the rack ears touch the front vertical rack rails.
• Use the captive screws on the rack ears to secure the enclosure to the middle holes (2 and 3) on the front vertical rack rail.

Important Note: The enclosure weighs 18.25 kg (40.2 lbs). Team-lift or use lift equipment when installing. ⚠️

4. Connect Management and Data Cables

Action: Connect management and data cables to the rear of the enclosure.

(Visual description: The rear of the enclosure is shown with management (MGMT) ports and data ports where cables are connected.)

5. Connect the Power Cable

Action: Connect the power cable.

Details: The enclosure has two power supply connections; install both power cords. The power range for this enclosure is 100V-240V AC.

(Visual description: Power cables are shown being plugged into the rear power supply units (PSUs) of the enclosure.)

6. Install Drive Carrier Assemblies

Action: Install Drive Carrier Assemblies.

Details: If you are not using Western Digital Drive Carrier Assemblies, refer to the Installation Guide section 1.5.1, "Drive Installation," for instructions to install an NVMe SSD onto a Drive Carrier.

(Visual description: Drive carrier assemblies are shown being inserted into the front of the chassis.)

7. Verify the LEDs

Action: Verify the LEDs are functioning correctly.

Details:

• Front of Enclosure: Power LED should be on.
• Rear of Enclosure: PSU LEDs and IOM LEDs should be green.

Important Note: Confirm that the PSU, Power, and IOM LEDs are green. If a Drive Assembly LED is amber, refer to the User Guide, section 1.2.1. ⚠️

(Visual description: Diagrams illustrate the front and rear views of the enclosure, highlighting the location and expected color (green) of Power, PSU, and IOM LEDs.)

8. Determine the Port IP Addresses

Action: Determine the IP addresses for the enclosure's management and data ports.

Primary Option (DHCP):

If a DHCP server is present, the enclosure's RJ45 management ports and QSFP28 data ports will be assigned IP addresses automatically. The naming convention used by the enclosure manager (EM) is:

• Management Ports: <enclosure name>-iom<a|b>-mgmt
• Data Ports: <enclosure name>-iom<a|b>-rfx<a|b|c>

The enclosure name follows these patterns:

• High availability: ofdata24-42xx-<serial number>-iom<a|b>-mgmt
• Non-high availability: ofdata24-41xx-<serial number>-iom<a|b>-mgmt

The enclosure serial number is located on the pull-out tabs on the front of the chassis.

Secondary Option (Static Link-Local):

If no DHCP server is available, the platform defaults to static link-local addresses in the 169.254.0.0/16 IP range for data and management ports. The hostname will include a ".local" suffix. Initial network configuration will require local access via the RJ45 management port to a directly connected host or laptop.

9. Discover and Connect to Devices

Action: Discover and connect to NVMe devices.

Procedure:

1. Open a terminal and use the nvme-cli utility with the adapter's IPv4 address to discover all NVMe™ devices installed on the fabric:
   # sudo nvme discover -t rdma -a <IP of IOM data port>
2. Review the output to find the subnqn associated with the device you wish to connect to.
3. Connect to the device using its subnqn:
   # sudo nvme connect -t rdma -i 16 -a <IP of IOM data port> -n <subnqn>
4. Verify the connection:
   # sudo nvme list -v

Reference: Please refer to the User Guide for detailed information, including TCP connection details. Consult section 4.1.3, "Discovering and Connecting to NVMe Devices Using the Open Composable API."
