Figure 50: Removing an AC Power Supply
Installing an M7i AC Power Supply
To install an AC power supply, follow this procedure (see Figure 51 on page 109):
1.
Verify that the switch on the power supply faceplate is in the
OFF
(
O
) position.
2.
Locate the power cord shipped with the router, which should be appropriate for your
geographical location (see “M7i Router AC Power, Connection, and Power Cord
Specifications” on page 164).
3.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect
the strap to one of the ESD points on the chassis. Verify that the router is attached to
a proper earth ground.
4.
Place one hand under the power supply and grasp the handle on the faceplate with
the other hand. Slide the power supply into the chassis until it contacts the midplane.
5.
Starting with the bottom screw, tighten (but do not overtighten) the thumbscrews
at each corner of the power supply faceplate.
6.
Insert the appliance coupler end of the power cord into the appliance inlet on the
power supply faceplate and insert the plug into an AC power source receptacle. Verify
that the power cord does not block access to router components or drape where
people could trip on it.
7.
Press the power switch on the faceplate to the
ON
(
|
) position. When the power
supply has powered on successfully, the green
OUTPUT OK
LED lights steadily.
