Connector and Cable Specifications  
Revised: January 12, 2012  
This appendix describes the Cisco ME 4924-10GE switch ports and the cables and adapters that you use  
to connect the switch to other devices.  
Connector Specifications  
These sections describe the connectors used with the switch.  
Connecting to 1000BASE-T Devices  
When connecting the ports to 1000BASE-T devices, such as servers, workstations, and routers, you must  
use a four-twisted-pair, Category 5, straight-through cable wired for 10BASE-T, 100BASE-TX, and  
1000BASE-T.  
When connecting the ports to other devices, such as switches or repeaters, you must use a  
four-twisted-pair, Category 5, crossover cable. Be sure to use a four-twisted-pair, Category 5 cable when  
connecting to a 1000BASE-T-compatible device.  
Note  
Use a straight-through cable to connect two ports only when one port is designated with an X. Use a  
crossover cable to connect two ports when both ports are designated with an X or when both ports do  
not have an X.  
SFP Module Ports  
The Cisco ME 4924-10GE switch uses SFP modules for fiber-optic and copper uplink ports. Refer to  
the Cisco ME 4924-10GE switch release notes for a list of supported SFP modules.
