Slot and Port Numbering
The Cisco MWR 2941 router chassis contains the following interface types:
• 16 T1/E1 ports, labeled “T1/E1”
• 4 RJ-45 jacks for copper Ethernet ports, labeled “100/1000” Ethernet
• 2 HWIC slots, labeled “HWIC0” and “HWIC1”
• 1 compact FLASH Type-II connector, labeled “Compact Flash”
• 2 SFP connectors for optical GE ports, labeled “GE0” and “GE1”
• 2 miniature coaxial connectors for 10MHZ and 1PPS timing
Note Miniature coaxial timing connectors are not included on all versions of the Cisco MWR 2941. You can
verify your hardware version with the VID label on the back of the router; routers labeled with a VID of
V01 or V02 do not include the timing connectors, while routers with VID V03 and higher include the
connectors.
• 1 RJ-45 connector for Console/Auxiliary, labeled “CON/AUX”
• 1 RJ-45 jack for BITS interface, labeled “BITS”
The logical slot numbers are 0 for all built-in interfaces.
The numbering format is:
Interface type Slot number/Interface number
Interface (port) numbers begin at logical 0 for each interface type.
