5 Carefully slide the power supply the rest of the way out of the switch.
Power supplies may become very hot during operation. Wear thermal protective gloves when you
remove a power supply from an operating switch.
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 232). Push the
power supply in until the latch snaps into place.

Do not slam the power supply into the switch.
8 Connect the power cord to the power supply and to a grounded AC power outlet.
Always be sure that the source outlet is properly grounded before plugging the AC power cord into
the AC power supply.
9 If the power supply is equipped with a power cord retainer, use the retainer to secure the power
cord to the power supply.
