system ventilation and EMI levels.

If the power supply is equipped with a power cord retainer, use the retainer to secure the power cord
to the power supply.

Warning
Always make sure that the source outlet is properly grounded before plugging the AC
power cord into the AC power supply.

Installing an 850 W Internal AC Power Supply
The Summit X650 series switch is shipped without installed power supplies.
The switch accommodates one or two Summit 850 W power supply units.
Caution
Make sure that the AC power supply circuit is not overloaded. Use proper overcurrent
protection, such as a circuit breaker, to prevent overcurrent conditions.
To install an 850 W AC power supply in a Summit X650 series switch, follow these steps:
1. Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to an
appropriate grounding point.
2. If necessary, remove a blank panel from the back of the Summit X650 series switch.
