1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
the ESD point on the chassis.
2. If the power supply slot has a power supply in it that needs to be removed, remove the power supply.
See
"Removing an AC or DC Power Supply from an XRE200 External Routing Engine" on page
3. Taking care not to touch power supply components, pins, leads, or solder connections, remove the new
power supply from its bag.
4. With one hand on the faceplate handle and the other hand on the bottom of the power supply to
support its weight, slide the power supply straight into the power supply slot until the power supply is
approximately halfway to the back of the external Routing Engine.
5. Remove your hand from the bottom of the power supply.
6. Gently slide the power supply straight into the chassis until the power supply is almost fully seated in
the slot. The power supply will reach a point where backpressure will prevent the power supply from
going further into the slot; do not force the power supply fully into the slot at this point of the procedure.
7. Use your thumb to move the ejector lever at the top of the power supply faceplate to the right, and
push the power supply flush into the back of the chassis. Release the lever.
