Removing and Replacing Cisco ASR 1000 Router eUSB Devices
This completes the procedure for replacing Cisco ASR1002-X Router DIMMs.
After you have correctly installed the DIMMs and reinstalled the route processor, the system should
reboot correctly.
If the system fails to boot properly or if the console terminal displays a checksum or memory error after
you have installed new DIMMs, ensure that all DIMMs are installed correctly. If necessary, shut down
the system and remove the route processor. 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. Then replace the route processor and reboot the system for
another installation check.
Note
If after several attempts 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 any other
indications that might help solve the problem.
Removing and Replacing Cisco ASR 1000 Router eUSB Devices
The Cisco ASR1000-RP1 and ASR1000-RP2 come with an embedded USB (eUSB) flash device that
functions as the route processor Non-Volatile Random Access Memory (NVRAM) and boot disk of the
route processor. The Cisco ASR1000-RP1 supports a 1 GB eUSB flash field-replaceable unit (FRU), and
the Cisco ASR1000-RP2 supports a 2 GB eUSB on the Cisco ASR 1006 Router and the Cisco ASR 1004
Router.
The Cisco ASR 1001 Router has only one eUSB on the chassis. It is located at the eUSB connector P26,
as shown in
Figure 14-29
. To replace this component, you must remove a screw on the mounting hole.
Note
The 8 GB eUSB on the integrated route processor is not an FRU on the Cisco ASR 1002 Router. The
Cisco ASR1000-RP2 is not supported on the Cisco ASR 1002 Router and the Cisco ASR 1001 Router.

Remove and Replace the eUSB Device on the Cisco ASR 1006 and Cisco ASR
1004 Routers
To remove the Cisco ASR1000-RP eUSB from the Cisco ASR 1004 and Cisco ASR 1006 router, follow
these steps:
Step 1
Before you physically replace the eUSB device, make a backup of startup-config and boot image to a
storage device. For example, to backup to an external USB flash drive, enter:
router# copy nvram:startup-config usb0
router# copy bootflash:asr1000rp1-adventerprisek9.02.01.00.122-33.XNA.bin usb0:
