5 Carefully slide the power supply the rest of the way out of the switch.
CAUTION
Power supplies may become very hot during operation. Wear thermal protective gloves when you
remove a power supply from an operating switch.
NOTE
If you are not installing a replacement power supply, install a cover over the unoccupied power supply
bay. Unoccupied bays must always be covered to maintain proper system ventilation and EMI levels.
6 Verify that the replacement power supply is oriented the same way as the unit you removed.
For a Summit X670 series switch, verify that the airflow direction of the power supply matches the
airflow direction of the switch.
7 Carefully slide the power supply all the way into the power supply bay (see Figure 287). Push the
power supply in until the latch snaps into place.
