Cisco Switches :: SPS2024 And SSL Certificate Import?

I am trying to import a SSL certificate into this device -  Cisco SPS2024 (FW: 1.0.6 ( date  30-Aug-2011 time  15:45:47 )) but without sucess. I have allready did this task on another models through CLI (Cisco SRW224G4 - through the lcli) or on Cisco SG300. I can create certificate request with:
 
switch(config)#crypto certificate 1 generate key-generate
switch#crypto certificate 1 request cn "sw.localdomain" or "..." ou "..." loc "..." st "..." cu "..."
 
and that last command  gives me plaintext certification request that I will sign with my certification authority. to this time, everything is clear and perfect.
 
And now, I have signed certificate according generated certificate request and I want to import it. And now I am in stuck, because I have not found any useful command to do this action. For import certificate, I have found only following command:
 
switch# crypto certificate 1 import pkcs12 WORD
 
also I dont exactly understand this command because there is no parameter to specify any url from which will be fetched pkcs12 certificate... just WORD parameter as the pkcs12 passphrase. nothing like as on another switch models on which there is following command:
 
switch2(config)# crypto certificate 1 import <CR>
 
after executing the command line will waiting for pasting the signed certificate to console. And on SPS2024 there is no any similar command to doing this. So in final, I cannot import certificate signed by my certificate authority, I can just generate self signed certificate directly on device and use only this one
