The gateway can be powered on by:
Connecting Power to an AC-Powered Gateway on page 39
Connecting Power to a DC-Powered Gateway on page 39
After connecting the gateway to the ground, you can connect an AC power cord to the gateway. For
AC power cord specifications, see "AC Power Cord Specifications" on page 77.
To connect the AC power cords to the gateway:
1.
Locate the power cord that has a plug appropriate for your geographical location; see "AC
Power Cord Specifications" on page 77.
2.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the
strap to one of the ESD points on the chassis. For more information about ESD, see
"Preventing Electrostatic Discharge Damage" on page 83.
3.
Insert the appliance coupler end of the power cord into the power supply receptacle in the
gateway.
4.
Insert the power cord plug into an AC power source receptacle.
5.
Repeat Steps 1 through 4 for the other power supply.
Warning: Verify that the grounding wire and the power cord do not block access to gateway
components or drape where people could trip on them.
You connect DC power to the gateway by attaching power cables from the DC power sources to
the terminal studs on the power supply.
Warning: Be sure the external power source is turned off before connecting power to the
gateway.
To connect the DC source power cables to the gateway:
1.
Verify that the DC power cables are correctly labeled before making connections to the power
