Hello [NAME],   You can refer to this spec sheet for SFP compatibility: [URL]   Just to clarify, X1000 series does not support stacking, only port-channel configuration. 
Hello all,  Im a little new to shopping for the transceiver modules. I have two X1052p switches that Id like to stack and I want to make sure that I will purchase the correct ones.  Thank you!
