Remove the OSFP module

Use this information to remove the OSFP module.

Procedure

1. Make preparations for this task.
   1. Remove the tray from the enclosure. See Remove a DWC tray from the enclosure.
   2. Remove the tray cover. See Remove the tray cover.
   3. Remove the cross braces. See Remove the cross braces.
   4. Remove the M.2 backplane assembly. See Remove the M.2 backplane assembly.
2. Disconnect the drive cage cable.

   From (carrier board in GPU node)	To (system board in compute node)
   1 MCIO 2	1 PCIe x 16 MCIO 4 connector
   2 MCIO 3	2 PCIe x 16 MCIO 1 connector
   3 MCIO 4	3 PCIe x 16 MCIO 2 connector
   5 Stud (in between the nodes) Make sure the cables are routed around the stud as shown in the illustration.

4. Disconnect the OSFP module cables from the network board on the GPU node.
   CAUTION

   • Hold the cable connector at 45 degree angle when inserting it into the port.

   • Have extremely precaution when reseating the connectors that have a 45 degree label on them as they are fragile and will get damage if not installed in the correct 45 degree angle.

   From OSFP module connectors	To Network board connectors
   1 Network connector (near GPU node)	1 Port 0
   2 Power connector P1	2 OOB port 0
   3 Power connector P2	3 OOB port 1 (on network board) and power connector (on carrier board)
   4 Network connector (near Compute node)	4 Port 1
   5 Stud (in between the nodes) Make sure the cables are routed around the stud as shown in the illustration.

5. Remove the three screws from the OSFP module.

6. Remove the OSFP module.
   1. Insert a flat head screwdriver into the gap between the OSFP module and the OSFP module conduction plate; then, rotate the flat head screwdriver to release the OSFP module from the conduction plate.
   2. Carefully hold the OSFP module by its edges and keep the OSFP module at an angle. Then, remove it from the compute node.
