Replacing Power System Components

For instructions on replacing power system components, see the following sections:

Replacing an AC Power Supply

An AC-powered router has two or more load-sharing AC power supplies. Each power
supply is hot-removable and hot-insertable, as described in
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis. Make sure the router
is attached to a proper earth ground. For more information about ESD, see
"Preventing Electrostatic Discharge Damage"
Verify that a rubber safety cap covers the SFP transceiver, installing one if
necessary.
Orient the SFP over the port in the PIC so that the connector end will enter the
slot first and the SFP connector faces the appropriate direction:
If the PIC has ten SFP ports, the ports are arranged in two columns. The SFP
connector faces to the right for ports in the left column, and to the left for
ports in the right column.
If the PIC has one or two SFP ports, the SFP connector faces to the left on
platforms in which FPCs install vertically in the chassis, and faces upward
on platforms in which FPCs install horizontally in the chassis.
Slide the SFP into the slot. If there is resistance, remove the SFP and flip it so
that the connector faces the other direction.
Remove the rubber safety cap from the transceiver and the end of the cable,
and insert the cable into the transceiver.
Arrange the cable in the cable management system to prevent the cable from
dislodging or developing stress points. Secure the cable so that it is not supporting
its own weight as it hangs to the floor. Place excess cable out of the way in a
neatly coiled loop in the cable management system. Placing fasteners on the
loop helps to maintain its shape.
Verify that the status LEDs on the PIC faceplate indicate that the SFP is functioning
correctly (there is an LED for each SFP port). For more information about the
PIC LEDs, see the M10i Internet Router PIC Guide. You can also verify PIC
functioning by issuing the
