Brocade ICX 6450 Stackable Switches Hardware Installation Guide - Manual (Page 18)

10/100/1000 BASE-T ports
All ICX 6430 and ICX 6450 devices provide 24 or 48 RJ45 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
ICX 6430 and ICX 6450 devices contain 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 stackable switch and can be used as uplink (data) ports or stacking ports.
The ICX 6430 contains SFP ports that support 1 Gbps port speeds but do not support 10 Gbps port
speeds. The ICX 6450 contains SFP+ ports that support 1 Gbps or 10 Gbps port speeds.
Ports 1 and 3 are default stacking ports. Default stacking ports are enabled to accept special stacking
packets during a CLI-initiated command sequence of the Secure Setup utility. If ports 1 and 3 are not
used as stacking ports, you can use them as data ports. Configuration is not required to use them as
data ports.
On the ICX 6450, ports 1 and 3 are 10 Gbps ports. Without a license at bootup, ICX 6450 ports 2 and
4 come up in 10 Gbps port speed in an error disabled state. To enable ports 2 and 4 to 10 Gbps port
speed, purchase the ICX6450-2X10G-LIC-POD license. For more information about enabling ports 2
and 4 to 10 Gbps port speed, refer to the FastIron Ethernet Switch Administration Guide. The
ICX6450-10G-LIC-POD license is not applicable toICX 6430 devices because there are no 10 Gbps
ports on the device.
For information about supported SFP and SFP+ transceivers, refer to the following Brocade website:

Specifying a port address
You can specify a port address for an uplink (data) port, 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. For the ICX 6430, range is from 1 to 4. For the ICX 6450,
range is from 1 to 8. If the device is not part of a stack, the stack unit ID is 1.
• slot --Specifies the slot number. Can be 1 or 2.
• port --Specifies the port number in the slot. Range is from 1 to 24 (24-port models) or 1 to 48 (48-
port models).
This example shows how to specify port 2 in slot 1 of a device that is not part of a stack:
