Installation preparation
1. Put on an ESD wrist strap and make sure it is correctly grounded.
2. Remove the blank panel (if any) from the slot to be used.
To ensure good ventilation, install blank panels in unused slots.
CAUTION:
•
Hold a power module by the bottom when moving it. Never attempt to lift a power module with its
handle because the handle is not designed to support weight. Doing so might result in bodily injury or
damage to the power module.
• Make sure the power switch is in the OFF position before installing a power module.
Installing a DC power module
1. Remove the air filter frame of the power module, and gently pull the DC power module handle out.
2. Holding the handle of the power module with one hand and supporting the bottom of the power
module with the other hand, insert the power module slowly along the guide rails to fully seat it in
the backplane, as shown in Figure 29 .
3. Fasten the mounting screws on the power module panel with a Phillips screwdriver.
4. Cover the power module with the removed air filter frame.
