1 Each port can operate at either 1G or 10G, and operates in a mutually exclusive way. You cannot insert both 1G and 10G together. If you insert IG IMs
(A900-IMA8T1Z, A900-IMA8S1Z, A900-IMA8T, A900-IMA8S), the dual rate port would support only 10G.
GigabitEthernet Copper Ports
Fixed copper GigabitEthernet (GE) interfaces are provided through standard RJ-45 connectors. These ports
support the following features:
• Standard 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.
• Digital optical monitoring as specified by the SFP.
• Any mix of SFPs is supported unless specifically noted.
Note
Smart SFPs are not supported on the router.
• 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
Copper based SFPs do not support synchronous ENET operations.
