Hello @csco20051988 ,

CRS-1 is the first generation of CRS and it was presented to us by Cisco in July 2005 with its new network operating system IOS-XR.

in 2012 CRS-3 was already avaialble and some service providers started to replace CRS-1 chassis with CRS-3 devices.

CRS-3 provided more bandwidth per slot.

The current model of this familly is the CRS-X.

 

have a look at the following link that provides a list of datasheets

 

https://www.cisco.com/c/en/us/products/routers/carrier-routing-system/datasheet-listing.html

 

Note:

CRS-1 and CRS-3 are so heavy that required special planning of the technical pavement . They are so big that require special purpose chassis or normal chassis but you cannot mount the front and rear doors.

The CRS1-4slot was a bad experience for me.

The CRS system has multiple fabrics linecards and router processors are installed on the front and media specific sub modules are installed on the back.

Look for the fabric linecards if I remember correctly CRS-1 uses FIP-80 and CRS-3 FIP-160 (the numbers here are just an example)

As an alternative ask to a colleague that have an acoount to access the system and to provide you the output of show version and show module (show inventory)

 

Hope to help

Giuseppe
