Control features
Each device front panel includes the following control features:
•Serial management interface (the DB9 port labeled Console)
•Out-of-band RJ45 management Interface
Serial management interface (DB9 Console port)
The serial management interface allows you to configure and manage the device using a
third-party terminal emulation application on a directly-connected PC. A straight-through EIA or TIA
DB9 serial cable (M or F) ships with the device. The serial management interface (the DB9 Console
port) is located in the left corner of the front panel.
Out-of-band RJ45 management interface
The out-of-band RJ45 management interface enables you to configure and manage the device
using a third-party terminal emulation application on a directly-connected PC.
Network interfaces for FCX624S, FCX648S, FCX624S-F, FCX624-HPOE, FCX648-HPOE
FastIron CX devices contain the following interfaces:
•10/100/1000 Mbps ports with RJ45 copper connectors
•100/1000 Mbps ports with mini-GBIC slots for SFP MSA-compliant fiber transceivers
•Optional 2-port 10Gbps Ethernet XFP module
•CX4 stacking ports

Network interfaces for FCX624-E, FCX624-I, FCX648-E, FCX648-I
FastIron CX devices contain the following interfaces:
•10/100/1000 ports with RJ45 copper connectors
•100/1000 ports with mini-GBIC slots for MSA-compliant SFP transceivers
•Optional 4-port 1Gbps Ethernet SFP module
•Optional 4-port 10Gbps Ethernet SFP+ module
FastIron CX 10/100/1000 BASE-T ports
All FastIron CX devices except for the fiber models contain 24 or 48 RJ45 ports that operate at 10
Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. FastIron CX fiber models
contain 24 or 48 SFP ports. Because all ports support automatic MDI or MDI-X operation, you can
use straight-through cables for all network connections to PCs or servers, or to other switches or
hubs. In addition, it is ideal and preferred to use straight-through cable for switch-to-switch
connections.
Each of these ports supports auto-negotiation, so the optimum transmission mode (half or full
duplex), and the data rate (10, 100, or 1000 Mbps) can be selected automatically. If a device
connected to one of these ports does not support auto-negotiation, the communication mode of
the port can be configured manually.
Combination ports
FCX devices contain four combination ports, which are four Small Form Factor Pluggable (SFP)
network interfaces (1F~4F) that are shared with four of the RJ45 ports (ports 1~4). In the default
configuration, if an SFP transceiver is installed in a slot and has a valid link on its port, the
associated RJ45 port is disabled and cannot be used. The switch can also be configured to force
the use of a combination RJ45 port or SFP slot, as required.
NOTE
FCX624-E, FCX624-I, FCX648-E, and FCX648-I devices do not ship with SFP ports. You must install
the optional SFP or SFP+ module for SFP support.

Optional two-port 10 Gbps XFP uplink module
The FCX624S, FCX648S, FCX624S-F, FCX624S-HPOE, and FCX648S-HPOE devices include a slot
on the front panel for a two-port 10 Gbps XFP uplink module. This module operates at 10 Gbps full
duplex, and is hot-swappable.
FIGURE 12 Two-port 10 Gbps XFP module
Optional Four-port 1 Gbps SFP and 10 Gbps SFP+ modules
The FCX624-E, FCX624-I, FCX648-E, and FCX648-I devices include a slot on the front panel for a
four-port 1 Gbps SFP module, or a four-port 10 Gbps SFP+ module. The 1 Gbps SFP module
operates at 1 Gbps full duplex, and the 10 Gbps SFP+ module operates at 10 Gbps full duplex.
FCX-I and FCX-E devices can be used in an IronStack by installing the optional 10 Gbps SFP+
module, and connecting devices using standard duplex LC cables. These devices cannot be
combined in a stack with non-FastIron CX devices. For detailed information about how to configure
FastIron CX devices in an IronStack topology, see the FastIron Configuration Guide.
NOTE
The 1 Gbps SFP and 10 Gbps SFP+ modules are not hot-swappable.

The two left ports on the SFP+ module do not pass regular Ethernet traffic by default. The stack
disable CLI command must be configured on these two ports in order for them to pass regular traffic.
16/10 Gbps Ethernet CX4 stacking ports
The FCX624S, FCX648S, FCX624S-F, FCX624S-HPOE, and FCX648S-HPOE devices include two
16/10 Gbps Ethernet CX4 ports on the rear panel (the stacking ports). The device can perform
data transmission directly through copper links of up to 3 meters.
The Up Link and Down Link LEDs on the front panel indicate operational status. If the Up Link or
Down Link LED is on, the port is connected. If the Up Link or Down Link LED is off, no connection
exists, or the link is down.
Cable specifications for CX4 stacking ports
The following cable specifications apply to the CX4 stacking ports:
•Support for 802.3ak or 10 Gbps Ethernet CX4 standard and 16 Gbps inter-unit stacking (up to
8 units in a stack)
•Support for cables up to 3 meters in length
•Requires latch-style receptacle or SFF-8470 plug
NOTE
FCX624-E, FCX624-I, FCX648-E, and FCX648-I devices can be added to a stack using the first two
ports on a four-port 10 Gbps SFP+ module (optional) using standard duplex LC cables.
