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 CES 2000 Series 2048C-4X, CES 2000 Series 2048F-4X, CER 2000 Series 2048C-4X-RT, and the CER 2000 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 CES 2000 Series 2048CX, CES 2000 Series 2048FX, CER 2000 Series 2048CX, and the CER 2000 Series 2048FX come
with two 10-Gigabit Ethernet ports installed. A 24-port CES 2000 Series, CER 2000 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
ports. 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 Extreme Networks. 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 Extreme Networks:
