The “Show Media Description” column in Table 2.1 shows the text that displays in the output of the show media
command for each connector type.
10/100/1000 Mbps Ports
The 10/100/1000 copper ports use auto-sensing and auto-negotiating to determine the speed (10 Mbps, 100
Mbps, or 1000 Mbps) and mode (full-duplex or half-duplex) of the port at the other end of the link and adjust port
speed accordingly.
10/100/1000 ports on the FGS devices support RJ-45 copper connectors. The output of the show media
command displays C next to the ports that have copper connectors installed.
Gigabit copper ports on the FGS models support auto MDI/MDIX detection. For more information about this
feature, see "Configuring MDI/MDIX" in the Foundry FastIron Configuration Guide.
100/1000 Mbps Ports
The 100/1000 fiber ports (ports 1F – 4F) on the FGS devices support the SFP fiber connectors listed in Table 2.1.
Combination Ports
Ports 1 – 4 of the copper ports and 1F – 4F of the fiber ports are combination ports, meaning either the copper
port or its corresponding fiber port can be active at a time. For example, for copper port 1 and fiber port 1F, only
one of these ports can be active at any given time. The same applies to copper port 2 and fiber port 2F, and so
forth. You can use a combination of fiber and copper ports or all four copper or all four 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 will select
the fiber or copper connector based on link availability. If a fiber link cannot be established, the device will select
the copper media.
10 Gbps Ports
This section describes the 10-GbE modules
1-Port 10-GbE Module
The 1-port 10-GbE module is installed in the FGS624XGP and FGS624XGP-POE (shown in Figure 2.4). This
module is factory-installed only. It is not a field-upgradeable module. This module is a 10-GbE fiber uplink for 10-
Gigabit Small Form Factor Pluggable (XFP) MSA-compliant optical transceiver.
Figure 2.7 shows the 1-port 10-GbE module. This port supports the 10-GbE connector types (10GBase) listed in
Table 2.1.

2-port 10-GbE Module
The 2-port 10-GbE module on the FGS is optional. You can order the FGS with one of these 2-port 10-Gigabit
module installed at the factory, or you can later upgrade your device.
The following 2-port 10-Gigabit Ethernet module is supported:
• 2-port 10-GbE fiber uplinks for 10-Gigabit Small Form Factor Pluggable (XFP) MSA-compliant optical
1 XFP port
