PowerConnect M6348 1 Gb Ethernet Switch I/O Module
The PowerConnect M6348 is a hot-swappable 48-port 1 Gb Ethernet switch.
While 16 ports are external uplink ports, the remaining 32 internal ports
provide connectivity to the blades within the enclosure with a maximum
bandwidth of 1 Gbps each. The PowerConnect M6348 switch also supports:
• Two integrated 10 Gb Ethernet SFP+ connectors
• Two integrated CX4 stacking connectors
• One console management connector
It is recommended that you use the PowerConnect M6348 switch with
quad-port mezzanine cards for maximum functionality. The quad-port
mezzanine cards and the PowerConnect M6348 Ethernet switch enable an
increased bandwidth (two 1 Gbps lanes), higher port density, and server
module consolidation.
