SPA Mate Cables
Note
The RPR mate cable is necessary only when the SPA is to be used in RPR mode. It is not needed in POS
mode. Support for the RPR feature is dependent on the platform software release feature content. Verify
support for the RPR feature support by reviewing the relevant SPA datasheets or by contacting your
Cisco representative.
