Appendix A RME Troubleshooting Tips and FAQs
Software Management
• AS5200 that runs Cisco IOS Software Release 11.2(10a)P or later.
• AS5300 that runs Cisco IOS Software Release 11.1(14)AA, 11.2(7a)P, or later.
Note Cisco AS5800 devices also have modems. However, the modem microcode for these devices is bundled
with the system software only and receives upgrades as part of the system software upgrade.
Q.
Which formats of Microcom firmware images does Software Management support?
A.
The Microcom firmware for 56K modems is available in two formats:
–
Controller firmware and the Digital Signal Processor (DSP) code as two files, for example,
mcom-modem-fw-xx.bin and mcom-modem-dsp-xx.bin.
–
A combination of firmware and the DSP code in a single format, for example,
mcom-modem-code-xx.bin.
The Cisco AS5300 supports only the image combination. If the Cisco AS5200 runs a Cisco IOS
Software release later than Cisco IOS Software Release 11.2(10)P, the AS5200 supports only the
combination file format.
Software Management supports only the combination format files (for example,
mcom-modem-code-xx.bin). Software Management does not support separate firmware and DSP
code files. You cannot import the files to the software library.
Q.
Which format of Modem ISDN channel aggregation (MICA) portware do Cisco 3600 devices
support?
A.
The 3640 digital modem network modules can run two types of modem microcode.
–
3600-Specific Modem Microcode File—This file has a 3600-specific header and should have
the characters c3600-mica in the file name. Software Management does not support such files.
–
Cisco AS5300 Modem Microcode File—In Cisco IOS Software Release 11.2(12)P, 11.3(2)T,
and later, the 3640 supports the AS5300 microcode files directly and the 3600-specific
microcode files.
The AS5300 microcode files have Executable and Linking Format headers that contain the
version and other information about the image file. Even though the microcode file formats
differ between the 3600 and the AS5300, the actual microcode that downloads to the MICA
modems is the same.
Software Management supports only AS5300 format files. Therefore, the earliest Cisco IOS
Software release that the 3640 supports is Cisco IOS Software Release 11.2(12)P.
Q.
Why does the Undo option not receive support for modem upgrades?
A.
To support the Undo option, Software Management must determine the version of software that runs
and identify the image file on the device that corresponds. The image file must be present in the
library or available on
Cisco.com.
In the case of modem upgrades, Software Management cannot precisely determine the current
software version on the modems in all cases. Moreover, different modems can run different software
versions, which makes the undo process difficult to support.
Q.
What connection mechanism does Software Management use for modem upgrades?
