Removing and Replacing the Cisco ASR 1001-X Router DIMM Memory Module
SUMMARY STEPS
1. Place the DIMM on an antistatic mat or pad while wearing an antistatic device, such as a wrist strap.
2. Remove the new DIMM from the antistatic bag.
3. Locate the polarization notch and align the DIMM with the socket before inserting it. See the below figure.
4. Gently insert the new DIMM, taking care not to damage the pins on the edge of the DIMM. Using two
hands, hold both sides of DIMM's top edges with your index fingers and thumbs and gently slide the
DIMM straight in to the socket. Press the top of the DIMM towards the socket, being careful to apply
force only on the DIMM that is parallel with the plane of the DIMM.
5. Use light insertion force and insert smoothly, but ensure that the DIMM is inserted straight. If necessary,
rock the DIMM gently back and forth to seat it properly. The following figure shows how to install the
DIMM in the socket for the Cisco ASR 1001-X Router.
6. After the DIMM is installed, check whether the release levers are flush against the sides of the DIMM
socket. If they are not, the DIMM might not be seated properly. If the DIMM appears misaligned, carefully
remove it according to the removal procedure and then reseat it in the socket. Push the DIMM firmly back
into the socket until the release levers are flush against the sides of the DIMM socket.
7. Repeat Step 4 through Step 6 for the remaining DIMM.
8. Replace the Cisco ASR 1001-X Router top cover:
9. Install the power supplies into the chassis. See:
DETAILED STEPS
Step 1 Place the DIMM on an antistatic mat or pad while wearing an antistatic device, such as a wrist strap.

Handle the DIMM by the edges only, and avoid touching the pins.
Step 2 Remove the new DIMM from the antistatic bag.
Step 3
Locate the polarization notch and align the DIMM with the socket before inserting it. See the below figure.
