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 450 W or 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.
Figure 203: Removing a Blank Panel
3. Verify that the power supply is right side up.
The power supply should be oriented as shown in Figure 204.
4. Carefully slide the power supply all the way into the power supply bay.
Figure 204: Installing a Power Supply
5. Push the power supply in until the latch snaps into place.
Caution
Do not slam the power supply into the switch.
6. To install a second power supply, repeat the procedure.
Note
If power supplies are not installed in both power supply bays, be sure to install a cover
over the unoccupied bay. Unoccupied bays must always be covered to maintain proper
system ventilation and EMI levels.
