NOTE
A few examples of the front and rear panels are shown. Other models have similar front and rear
panels.
The console management interface is a mini-USB port that allows you to configure and manage the
device using a third-party terminal emulation application from a directly connected PC or through a
terminal server.
Out-of-band management interface
The out-of-band management interface is an RJ-45 port that allows you to access, configure and
manage the device from the network.
System reset button
The reset button allows you to restart the system without switching the power supply off and on, using
the CLI. When the reset button is pressed, the system resets and the software is reloaded. The button
is accessible through a hole labeled RESET in the front panel.
Network interfaces for devices
The devices contain the following network interfaces.
• 10/100/1000 Mbps ports with RJ-45 copper connectors
• SFP or SFP+ ports
SFP ports support 1 Gbps port speed. SFP+ ports support both 1 Gbps and 10 Gbps port speeds.
NOTE
Refer to the Brocade ICX 7250 Switch Technical Specifications on page 73 to see the ports supported
by your model.
Slot designations
Refer to Network and management interfaces on page 14 for the location of slot 1 and slot 2 on the
front panel of the 24-port models and the 48-port models.
Slot designations for ICX 7250 devices TABLE 3
DeviceSlot 1 (10/100/1000 BASE-T ports)Slot 2 (SFP and SFP+ ports)
All devices provide 24 or 48 RJ-45 ports that operate at 10 Mbps or 100 Mbps half or full duplex, or at
1000 Mbps full duplex. Because all ports support automatic MDI or MDI-X operation, you can use
straight-through cables for all network connections to PCs, servers, or other devices or hubs. In
addition, it is ideal (and preferred) to use straight-through cables for switch-to-switch connections.
Each port 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.
SFP or SFP+ fiber ports
The ICX 7250-24G contains four small form factor pluggable (SFP) ports (ports 1 through 4). The top
row consists of ports 1 and 3, and the bottom row consists of ports 2 and 4. These ports reside on slot
2 of the switch and can be used as uplink (data) ports. These ports support 1 Gbps but not 10 Gbps
port speeds.
All other ICX 7250 devices contain eight SFP+ ports that support 1 Gbps or 10 Gbps port speeds. The
top row ports are odd numbered (ports 1, 3, 5 and 7) and the bottom row ports are even numbered
(ports 2, 4, 6 and 8). All ports can be used for stacking or up-linking.
NOTE
You may need software licenses to enable some SFP+ ports at the full 10 Gbps. Check the FastIron
Ethernet Switch Software Licensing Guidefor more information.
For information about supported SFP and SFP+ transceivers, refer to the Brocade Optics Family
datasheet.
Specifying a port address
You can specify a port address for an uplink (data) port, a stacking port, or a management port.
Specifying a data port
The port address format is stack_unit/slot/port, where:
• stack_unit --Specifies the stack unit ID. The range is from 1 through the maximum number of
devices supported in a stack. Refer to the technical specifications for your device for the actual
value. If the device is not part of a stack, the stack unit ID is 1.
• slot --Specifies the slot number; either 1 or 2.
• port --Specifies the port number in the slot. The range is from 1 through 24 (24-port models) or 1
through 48 (48-port models) for the RJ-45 ports. For the SFP ports, the range is from 1 through 4,
and for the SFP+ ports, the range is from 1 through 8.
This example shows how to specify port 2 in slot 1 of a device that is not part of a stack:
Brocade (config) # interface ethernet 1/1/2
Specifying a stacking port
The port address format is stack_unit/slot/port where:
• stack_unit --Specifies the stack unit ID. For models that support stacking, the range is from 1 through
the maximum number of devices (units) that can be supported in the stack.
• slot --Specifies the slot number. Stacking ports are in slot 2.
• port --Specifies the port number in the slot.
This example shows how to specify stacking port 3 in slot 2 of unit 3 in a stack:
Brocade (config) # interface ethernet 3/2/3
Specifying a management port
The management port number is always 1. This example shows how to specify the management port:
Brocade (config) # interface management 1
Port, system, and power status LEDs
The devices include LEDs that indicate the status of device components.
NOTE
Some examples of the port status LEDs are shown below. LEDs for similar ports are present for models
with higher number of ports.
FIGURE 6 Port status LEDs on RJ-45 ports
1. RJ-45 ports
2. Status LEDs for corresponding ports
3. PoE/PoE+ LEDs for corresponding ports
NOTE
The PoE/PoE+ LEDs are reserved on models that do not support PoE or PoE+ operation.
(Hardware can display 1-19 Stack
ID. The 10+ LED is used in
conjunction with another, 1-9, to
indicate numbers higher than 10.
The actual number of devices
supported in a stack is 12.)
Power supplies
The devices have one standard, C14, AC power supply receptacle on the rear panel of the device for
the AC power cord. In addition, there is an optional connector on some models for the power cord from
an external power supply (EPS4000) that can provide DC power to the device in the event the internal
power supply fails or for supplemental power for PoE or PoE+ applications.
The following figure shows an example of a typical rear panel for an ICX 7250 device.
FIGURE 10 ICX 7250 power supply connectors

Power supply usage
The device models support specific AC power supply inputs and numbers of PoE and PoE+ ports with
an internal power supply.
NOTE
Depending on the configuration, each EPS4000 connection from the device to the EPS4000 can add
23 ports of PoE (Class 3) or 12 ports of PoE+ power (54-volt supply) in addition to the internal power
supply by providing system power backup. If the overall PoE requirement is less than the power
budget of 360 W (or 720 W), the device can support 24 (or 48) PoE. The system power (12-volt
supply) portion of the EPS can be used for internal system power redundancy.
