Upgrade 1750-4v to have 2 VIC-E/M

[henry-lai]

Existing Cisco 1750-4v has one WIC-1T and 1x VIC-FXO, 8MB Flash and 32DRAM.

But I need to extend the voice to 2 VIC-2E/M, hence I need to remove exisitng VIC-FXO.

I have one questions, if I need to add 2 VIC-2E/M (remove existing VIC-FXO), do I need to upgrade DRAM. Flash ram, I think it is ok as IOS is not required to change (now is IP Voice).

Do Cisco has tools to check this kind of upgrade ? I can't use Configuration agent to treat as new configuration as Cisco 1750 is EOL.

You will have to be careful about the PVDM (Packet Voice DSP Module) requirements.The PVDMs hold DSPs that make the card fully functional. These PVDMs are installed on the motherboard within the 1750. To figure out the PVDM requirements with your setup, please refer to the document at the URL: http://www.cisco.com/univercd/cc/td/doc/product/voice/ics7750/hinstall/h_pvdm.htm#89332
