are required for the blower assembly replacement:
• Replacement blower assembly

Removing a blower assembly
To remove a blower assembly:
CAUTION: Wear a grounded ESD strap when handling DC04 SAN Director components. The
Director chassis provides a grounding connection above the power connectors. Also, store
ESD-sensitive components in antistatic packaging.
1. Before removing a blower assembly, verify that the other blower assembly is functioning
correctly. The power LEDs should be steady green.
2. Use the screwdriver to loosen the captive screws at the left and right of the blower assembly.
3. Grasp the handle and pull, sliding the blower assembly from the chassis and supporting the
blower assembly from beneath as you remove it (see Figure 42 (page 79)).
Installing a blower assembly
To install a blower assembly:
1. Orient the blower assembly and slide it into the chassis, pushing firmly to ensure that it is
seated.
2. Verify that the power LED displays a green light.
3. Use the screwdriver or your fingers to tighten the captive screws.
