Removing and Replacing FRUs from the Cisco ASR 1000 Series Routers
Minimum Requirements of eUSB Devices Supported on Cisco
ASR 1000 Series Routers
This section provides details regarding addition of an output message, indicating whether the eUSB device
currently used on the Route Processor (RP) is correct or the eUSB device is of less capacity and is incompatible
with the RP. This additional message has been introduced for the ASR 1000 Chassis Types (2,4,6,13RU) in
Cisco IOS XE Release 2.3.0S. Additionally, this change specifically for Cisco ASR 1001 Router Chassis has
been introduced in the Cisco IOS XE Release 2.4.0S.
Previous Behavior
Some of the Cisco ASR 1000 Series Routers were shipped with low-capacity eUSB devices on the
Route-processor boards. It is not an easy way to detect the presence of an invalid eUSB device with low
capacity on the RP. As the RP boards has already been shipped, it is important to provide information about
the presence of an incorrect eUSB device or a eUSB device with less capacity. Earlier, an additional
informational message was not displayed even if the eUSB device was of less capacity for the RP used on
the system.
Corrective Action Required
If the eUSB device is of less capacity and is not compatible as indicated in the Cisco IOS message then you
need to contact Cisco System Inc. and get the eUSB replaced. Prolonged use of routers with less capacity
eUSB devices would result in unpredictable behavior.
New Behavior
From Cisco IOS XE Release 2.3.0 onwards, an additional message is displayed on the auxiliary port and on
the Cisco IOS console port, providing information whether the eUSB device currently used is correct. For
Cisco ASR 1001 Router, this change for eUSB compatibility has been implemented from Cisco IOS XE
Release 2.4.0S onwards. The recommended eUSB devices with the minimum memory capacity for the RP
types compatible are:
