Network interfaces
This section describes the port types in the Brocade NetIron CES Series, Brocade NetIron CER Series
2000 series devices.
10/100/1000 Mbps ports
The 10/100/1000 ports on the device use auto-sensing and auto-negotiating to determine the speed (10
Mbps, 100 Mbps, or 1000 Mbps) and duplex mode (full-duplex or half-duplex) of the port at the other
end of the link and adjust port speed accordingly.
Combination ports
On devices with combination (combo) ports, one port out of each pair of copper and fiber ports can be
active at a time. Combo ports are numbered 1-4. For example, you can use either copper port 2 or fiber
port 2, but not both at the same time. You can use a combination of fiber and copper ports or all copper
or all fiber ports, as needed.
If you attach both the copper and fiber connectors for a port to the network, the fiber connectors take
precedence over the copper connectors. These ports support true media automatic detection, meaning
the device selects the fiber or copper connector based on link availability. If a fiber link cannot be
established, the device selects the copper media.
10-Gbps ports
The Brocade NetIron CES Series 2048C-4X, Brocade NetIron CES Series 2048F-4X, Brocade NetIron
CER Series 2048C-4X-RT, and the Brocade NetIron CER Series 2048F-4X-RT come with four 10-
Gigabit Ethernet ports installed. The four 10-Gigabit Ethernet uplink ports support 10-Gigabit Small
Form Factor Pluggable (SFP+) MSA-compliant optical transceivers
The Brocade NetIron CES Series 2048CX, Brocade NetIron CES Series 2048FX, Brocade NetIron CER
Series 2048CX, and the Brocade NetIron CER Series 2048FX come with two 10-Gigabit Ethernet ports
installed. A 24-port Brocade NetIron CES Series,Brocade NetIron CER Series has a slot to
accommodate a 2-port 10-Gigabit Ethernet module. If your 24-port device does not include a 10-GbE
module, you can optionally install one. Refer to
. The two 10-Gigabit Ethernet ports use
10-Gigabit Small Form Factor Pluggable (XFP) MSA-compliant transceivers.
Supported optics
100/1000 Ethernet Ports
The Ethernet Interface module contains 24 or 48 physical ports, through which you can connect your
device to other network devices at a speed of 100 Mbps or 1 Gbps.
Into a physical port, you must insert a fiber-optic transceiver provided by Brocade. The SFP-compliant
fiber-optic modules provide an optical transceiver or physical medium-dependent (PMD) interface for
fiber that can be used with the LAN physical layer (PHY)
The following 100 Mbps and 1 GbE optical transceivers are available from Brocade:
