c. If more than one power supply units are to be installed, start with the lowest available number
of PSU slot.
Step 2. Insert the hot-swap power supply into the slot until the release latch clicks into place.
Important:
• During normal operation, each power-supply slot must contain either a power supply or power-
supply filler for proper cooling.
• Make sure to follow the instruction on the guiding label in each slot. For slot 1, the power supply
unit must be installed with the fan downward; for slots 2 and 3, the power supply units must be
installed with the fan upward.
• After docking the power supply, hold the handle and slightly pull the power supply to make sure
that it is securely engaged and cannot be pulled out.
