The Model 5625HD switch module provides 24 RJ-45 10/100 Mb/s
autonegotiating switched Ethernet connections for the Model 500xBH/BHC
ATM/Router Backplane for the System 500x chassis. The switch module
combines the powerful ATM capabilities of the Centillion platform with the
connectivity features of the Model 500xBH chassis.
For Ethernet connectivity, the Model 5625HD switch module RJ-45 connectors
accept Category 3 and 5 unshielded twisted pair (UTP) or shielded twisted pair
(STP) cable connections. For more information about cabling, refer to
Appendix B, “

Note:
Category 3 UTP cable can be used only for fixed 10 Mb/s port
operation. It is not used for 100 Mb/s or 10/100 autonegotiating port operation.
