Introduction
The Cisco ASR 901 Series Aggregation Services Router is a cell-site access platform specifically designed to aggregate and transport mixed-generation radio access network (RAN) traffic. The router is used at the cell site edge as a part of a 2G, 3G, or 4G RAN.
The Cisco ASR 901 router helps enable a variety of RAN solutions by extending IP connectivity to devices using Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Node Bs using High Speed Packet Access (HSPA) or Long Term Evolution (LTE), base transceiver stations (BTSs) using Enhanced Data Rates for GSM Evolution (EDGE), Code Division Multiple Access (CDMA), CDMA-2000, EVDO, or WiMAX, and other cell-site equipment.
It transparently and efficiently transports cell-site voice, data, and signaling traffic over IP using traditional T1 and E1 circuits, as well as alternative backhaul networks such as Carrier Ethernet and DSL, Ethernet in the First Mile (EFM), and WiMAX. It also supports standards-based Internet Engineering Task Force (IETF) Internet protocols over the RAN transport network, including those standardized at the Third-Generation Partnership Project (3GPP) for IP RAN transport. Custom designed for the cell site, the Cisco ASR 901 router features a small form factor, extended operating temperature, and cell-site DC input voltages.
Table 1 lists the Cisco ASR 901 router model versions.

When the router boots up, it displays the following traceback messages: "*Mar 19 23:45:24.371: %LICENSE-2-UNRECOVERABLE: The IOS license storage on this device was not recovered. UDI=A901-12C-FT-D:FHAK1234567
*Mar 19 23:45:24.375: Following corrupted license storage was un-recoverable : lic0:/lservrc.pri
*Mar 19 23:45:24.375: -Traceback= 265C5A8z 60DC228z 60D97C8z 60D9F64z 580B534z 580573Cze"
These tracebacks may also appear while trying to install a license.
There is no functionality impact, it can be safely ignored.
