GigabitEthernet Copper Ports

GigabitEthernet Copper Ports
Fixed copper GigabitEthernet (GE) interfaces are provided through standard RJ-45 connectors. These ports
support the following features:
• Standard 10/100/1000Base-T/TX operation with forced or auto-negotiation for speed and duplex.
• Automatic crossover (auto-MDIX) for straight-through and crossover connections.
• Pause flow control as defined by the 802.3x standard.
• Frame size of 9216 bytes.
• Synchronous ENET operation that provides its recovered receive clock as an input clock source for the

GE SFP Ports

The GE SFP ports support the following features:
• 100Base-FX and 1000Base-X SFP modules.
• Copper SFP modules
• Digital optical monitoring as specified by the SFP.
• Any mix of SFPs is supported unless specifically noted.
• Pause flow control as defined by the 802.3x standard.
• Frame size of 9216 bytes.
• Synchronous ENET operation that provides its recovered receive clock as an input clock source for the
Note Copper based SFPs do not support synchronous ENET operations.

SFP+ Ports

The SFP+ ports support the following features:
• Digital optical monitoring as specified by the optical transceiver module.
• Any mix of SFPs is supported unless specifically noted.
• Pause flow control as defined by the 802.3x standard.
• Frame size of 9216 bytes.
