Help!! Have 2 chassis AS5300 (one more older than other) (+ inside )

[azamy]

More older unit can't define two modules with MICA modems (240 mdms in a whole). More newer unit define them without problems.

But both units define a module with 8 E1 ports.

What can be a problem? I have "sh tech" output in a files for both units and can send it to an expert who will try to help me.

When you say older unit do you mean older IOS? The carrier card for the 12 port modem module is AS53-CC2-DM...This can be used for both the 6 & 12 port modules. Ensure you have the CC2 card.

Thanks, Mak.

Mak

only with AS53-CC2-DM we can put 240 MICA modems to the case.

one unit is manuf. 1999 and the second at 2000

Also I have following message during "sh tech" at "old" unit:

ROM: System Bootstrap, Version 11.2(9)XA, RELEASE SOFTWARE (fc2)

at more newer one this message looks like this:

ROM: System Bootstrap, Version 12.0(2)XD1, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1)

but at one cisco document I saw that double density modem card will work with boot code ver. 12 and late.

is this difference causes a problem with identification of installed cards in older unit?

You are right..you need to have a boot code 12.0(2)XA, 12.0(3)T, 12.1(1), 12.1(1)T, 12.1(5)T or later in oder to get AS53-CC2-DM recognized in the system.

Following is the url which discuss exactly the same. visit table 2.

So upgrading the bootcode will resolve the issue.

Thank you for yor response

Pls say where can I get a step-by-step explanation of upgrading procedure?

I have to replace a ROM chip from my chassis to one with new verion ?

or old version of boot code from my ROM-chip can be replaced by the new one without changing a chip itself? who can do it? I have to ask the nearest Cisco partner?
