CAUTION: Do not mix AC and DC power supplies within the same device. Damage
to the device might occur.
To power on a DC-powered services gateway:
Verify that an external management device is connected to one of the Routing

Management and Alarm Devices" on page 57.
Turn on the power to the external management device.
2.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
3.
connect the strap to one of the ESD points on the chassis. For more information
about ESD, see "Preventing Electrostatic Discharge Damage" on page 152.
Verify that the power supplies are fully inserted in the chassis.
