Cisco 800 Series Router Working without Memory

Hello Guys,

I had a power problem with my 891 router and for that reason the 256 memory in in the router got blown,i realised that when i take off the memory,the router works perfect but when i put another memory,it becomes very hot and all the lights on the router stays up and never goes off.I have now took off the 256 memory and the router is functioning,i want to know negative side of using the router without the memory card.And if i can continue to use it without the memory for good. Thank You.

im guessing that it isnt your memory that is blown, but rather the memory slot of the router.

and i think that the it will runs just fine without the 256 dimm, because according to this article your router has 512mb by default.

but you can run into problems with future ios versions or features.

so with the future in mind i would see if you could RMA it, or swap out the motherboard to gain a fully functioning device.

Hi Easamoah, i found a RMA

Hi Easamoah,

 

i found a RMA form on the Cisco site with the rules and numbers for you to use to find out if you can send the modem to Cisco for repair.

http://www.cisco.com/c/en/us/td/docs/rma/3582.html

 

but i guess its cheaper, to look on ebay for a 2nd hand one, and just swap out the motherboard of the modem.

and i sugest you place a surge protected poweroutlet, to hopefully prevent future burn-outs.

 

let me know if you need any help, ill see what i can do
