Cisco 1921 replacing Cisco 1811

[kpare]

We're putting a 1921 in a remote data center to replace an 1811, but we can't find out for certain if we need to order new

rack mount ears? It seems like we can use the ears from the 1811 on the 1921, but can't confirm anything.

Does anyone know if this is true?

Hi,

As per the part number of rack mounting kits of routers are different like 1800 has  ACS-1811-RM-19= and 1900 is having WS-C1924-XL-EN (STK-RACKMOUNT-1RU) for rack mounting kits , They can connected with each others screws but the  original fitting will not be there as if like when they mounted with there original kits.

Hope to Help !!

I managed to get my  hands on an 1811 to compare to the 1921. The 1921 is slightly wider, but all the holes match up.

The 1811 uses part# ACS-1800-RM-19 and the 1921 used ACS-1900-RM-19

You are thinking a 1900 switch, they are a full 19" wide so they would fit properly into a rack.
