RAM and flash memory type ISR 4321 cisco

[Dhikra Marghli]

Hello

i have a router ISR 4321 CISCO have 4 GB RAM AND 4 GB Flash  and i want to add other DRAM and memory Flash !!

1- how i can know kind of RAM that i can add to ISR 4321 cisco  and kind of memory Flash in router !!

what's command or how i can type of RAM in ISR 4321 CISCO !!! ??

cisco ISR4321/K9 (1RU) processor with 1714961K/3071K bytes of memory.
Processor board ID FDO2307A2Y7
Router operating mode: Autonomous
2 Gigabit Ethernet interfaces
4 Voice FXO interfaces
32768K bytes of non-volatile configuration memory.
4194304K bytes of physical memory.
3125247K bytes of flash memory at bootflash:.

so please , i need from expert Router help me and give me the link or command show type memory !!

thanks in advance

here is the datasheet right side last one show the model of your router what RAM you need :

here is the video 2 parts replace the RAM, this is model of 4331 but should be the same(or near by).

hi,

it seems you're running voice on the router (FXO)

you can use the show inventory to check for the RAM installed (PVDM4-32 by default).

you can upgrade/replace the RAM by opening the router chassis. see helpful link below:

http://wannabelab.blogspot.com/2017/01/installing-pvdm4-64-and-nim-2fxs-on.html

it's for a 4331 PVDM4-64 but it shares the same architecture for a 4321 ISR. it only has 1x PVDM slot.

for ISR 4321 cisco , !!!

this router does not include PVDM  !!!!??

I need what type of card RAM ( name ) and type of flasm memory that help install in router  !!

i send a picture  about ISR 4321 cisco 

i wait a reply for this request 

thanks in adv

You need single Module DIMM and if you can purchased SSD will be good for your requirement.

[balaji.bandi]

here is the document : covers both DIMM and FLASH (if you like to increase and have free Slot)
