A Cisco uBR7200 series router requires 256 MB of DRAM memory on the NPE processor card when
Note
HCCP redundancy is configured and the router is supporting more than 3,000 cable modems. Using
less memory in these conditions results in temporary out-of-memory situations and incomplete
synchronization between the Working and Protect interfaces.

12.2 CX Images and Requirements

The 12.2 CX releases are based on Cisco IOS Release 12.2(15)BC1, which is a child of Cisco IOS
Release 12.2(15)T. The 12.2 BC train is an interim release train that provides DOCSIS 1.1 two-way
support, along with fixes for software caveats and support for selected new features.
The latest image in the 12.2 CX release train, Cisco IOS Release 12.2(15)CX1, provides two different boot
images for the Cisco uBR7200 series routers:
•
•
This difference in boot images affects only the ability of the Cisco uBR7246VXR router to boot over the
WAN interface. When the router has successfully loaded the Cisco IOS software, it has connectivity over
all of the port adapters that this particular version of Cisco IOS software supports.

series universal broadband routers for Cisco IOS Release 12.2(15)CX1. Cisco uBR7200 series routers
are only available with a 48 MB or 128 MB of Flash disk memory on the I/O Controller cards. The
UBR7200-NPE-G1 uses only compact Flash disk.

ubr7200-kboot-mz.122-15.CX.bin
The "kboot" version of the boot image is a new version of the boot image software that can run only
on the Cisco uBR7200-NPE-G1 processor and the UBR7200-I/O-2FE/E I/O controller, because it is
too large to load on the other I/O controllers. This image contains support for almost all supported
port adapters, allowing the Cisco uBR7246VXR router to boot over almost any type of WAN
interface.
ubr7200-boot-mz.122-15.CX.bin
The "boot" version of the boot image is small enough to be loaded on I/O controllers with 4MB of
Flash memory, but it supports only Ethernet, FastEthernet, Gigabit Ethernet, OC POS, and a limited
number of ATM port adapters. If you are using a serial port adapter or most ATM port adapters, you
will not be able to boot over the WAN interface.
