Figure 92. Secure the cold plate retainer screw

c) Return the service hook to its latched position on the bracket.

7. Replace the air baffles you removed.
8. Place the protective covers on the bottom of the replaced GPUs.

This protects the pins when returning the GPU.

What to do next
Prepare the system for operation. For instructions, see “Preparing the 8335-GTC, 8335-GTG, 8335-GTH,

8335-GTW, or 8335-GTX system for operation after you remove and replace internal parts” on page 202.
