When installing an AC power supply, be sure to observe the following precautions:
Warning
To prevent an electrical hazard, make sure that the AC power cord is not connected to the
power supply before you install the power supply in the power supply bay.
Caution
Make sure the AC power supply circuit is not overloaded. Use proper overcurrent protection,
such as a circuit breaker, to prevent overcurrent conditions.
To install a Summit 550 W power supply (AC power), follow these steps:
1 Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to an
appropriate ground point on the rack.
2 If necessary, remove a blank panel from the rear of the switch.

3 Verify that the power supply is right side up.
The power supply should be oriented as shown in Figure 169.
4 Carefully slide the power supply all the way into the power supply bay.
