Removing and Replacing the Cisco ASR 1000 Series DIMM Memory Modules
b.
Tighten the top surface screws and then the three screws on the front faceplate.
Step 9
Install the power supplies into the chassis. See:
•
Installing AC Input Power to Cisco ASR 1001 Router, page 12-34
•
Installing DC Input Power on the Cisco ASR 1001 Router, page 12-38
This completes the procedure for replacing the Cisco ASR 1001 Router DIMMs.
After you have correctly installed the Cisco ASR 1001 Router DIMMs, the system should reboot
properly.
If the system fails to reboot properly or if the console terminal displays a checksum or memory error
after you have installed new DIMMs, check the following:
•
Ensure that all the DIMMs are installed correctly. If necessary, shut down the system and remove
the chassis cover. Check the DIMMs by looking straight down on them to inspect them at eye level.
The DIMMs should all be aligned at the same angle and the same height when properly installed. If
a DIMM appears to stick out or rest in the socket at a different angle from the others, remove the
DIMM and reinsert it. Replace the top chassis cover, and reboot the system for another installation
check.
•
Ensure that all the DIMMs are from the same manufacturer and part number.
Note
After several attempts, if the system fails to restart properly, contact a service representative for
assistance. Before you call, make note of any error messages, unusual LED states, or other indications
that might help solve the problem.
Removing and Replacing the Cisco ASR 1002-X Router DIMM Memory Modules
Perform the following steps before you begin:
•
Use an ESD-preventive wrist strap.
•
Back up data that you want to save before replacing a eUSB device.
•
Note that the component is keyed and slotted for easier connection.
•
To ensure that the DIMMs function correctly, all the DIMMs must be replaced at the same time. In
addition, you must ensure that all the DIMMs are from the same manufacturer and have the same
part number, because manufacturers may have multiple versions of a DIMM.
