Hi Everybody,


My customer has installed a 3825 ISR with this characteristics:


ROM: System Bootstrap, Version 12.3(11r)T2, RELEASE SOFTWARE (fc1)


System image file is "flash:c3825-adventerprisek9-mz.124-4.T4.bin"

Cisco 3825 (revision 1.0) with 222208K/39936K bytes of memory.

Processor board ID FTX0949A01V

2 Gigabit Ethernet interfaces

4 Serial(sync/async) interfaces

1 ATM interface

1 Channelized E1/PRI port

1 Virtual Private Network (VPN) Module

4 Voice FXS interfaces

DRAM configuration is 64 bits wide with parity enabled.

479K bytes of NVRAM.

62720K bytes of ATA System CompactFlash (Read/Write)


As you can see it has 1 NM-1A-E3 and they want to install new one in the other slot available but we are not sure if that is possible. i mean, a router 3825 ISR can support 2 NM-1A-E3?


We checked datasheet but the info is no really clear.

Should be possible, of course being an access router depending on features enabled the CPU may be stressed a bit, better would be to use two independent routers, or one bigger 3845.


Hope this helps, please rate all useful posts!

thank a lot for your help about E3 ATM card in ISR 3825. indeed i checked the datasheet that is mentioned by other engineer here, but it doesnt result so helpful. my idea was confirm the info i got from a few sites here in cisco.


i send you an answer about your ISDN's question here in venezuela. i hope it help you.

Thanks Amit. It is a little bit of a peculiar datasheet as it doesn't mention a "supported" maximum number, rather just a "recommended" number. And I agree with this recommendation.

Anyway, the online configuration tool allows two modules in a 3725.
