The primary copy of SR OS software is located on a compact flash card. The removable 
media is shipped with each router and contains a copy of the OS image.
Note: 
• The modules contain three slots for removable compact flash cards. The drives are 
named Compact Flash Slot #1 (cf1), Compact Flash Slot #2 (cf2), and Compact Flash 
Slot #3 (cf3). Configurations and executable images can be stored on flash cards or an 
FTP file location. There are six Compact Flash slots on the 7750 SR-c12, three for 
CFM-A and three for CFM-B.
