Console management interface
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.
Network interfaces for devices
The Brocade ICX 7250 contains 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 101 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.
TABLE 2 Slot designations for ICX 7250 devices
Device Slot 1 (10/100/1000 BASE-T ports) Slot 2 (SFP and SFP+ ports)
Brocade ICX 7250-24G RJ-45 ports 1-24 SFP ports 1-4
Brocade ICX 7250-24 RJ-45 ports 1-24 SFP+ ports 1-8
Brocade ICX 7250-24P RJ-45, PoE/PoE+ ports 1-24 SFP+ ports 1-8
Brocade ICX 7250-48 RJ-45 ports 1-48 SFP+ ports 1-8
Brocade ICX 7250-48P RJ-45, PoE/PoE+ ports 1-48 SFP+ ports 1-8
10/100/1000 BASE-T 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 Brocade ICX 7250-24G contains four small form-factor pluggable (SFP) ports (ports 1 through 4). The top row contains odd-
numbered ports and the bottom row contains even-numbered ports. 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 Brocade 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
uplinking.

53-1003898-02 15

NOTE
You may need software licenses to enable some SFP+ ports at the full 10 Gbps. Refer to the FastIron Ethernet Switch Software
Licensing Guide for more information.
For information about supported SFP and SFP+ transceivers, refer to the Brocade 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 :
∙ 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.
The following example shows how to specify port 2 in slot 1 of a device that is not part of a stack:
device (config)# interface ethernet 1/1/2
Specifying a stacking port
The port address format is stack-unit/slot/port :
∙ 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.
The following example shows how to specify stacking port 3 in slot 2 of unit 3 in a stack:
device (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:
device (config)# interface management 1
Port, system, and power status LEDs
The devices include LEDs that indicate the status of device components.
NOTE

(Switch ID in the stack) The switch can display up to 19 switch IDs. The
10+ LED is used in conjunction with the 1
through 9 LEDs to indicate numbers greater
than 10. The 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 an AC power cord that uses a C13
connector. 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.
