Overview
Hardware features
Network interfaces for devices
The Ruckus 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 Ruckus ICX 7250 Switch Technical Specications on page 95 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 3 Slot designations for ICX 7250 devices

Ruckus ICX 7250-24G RJ-45 ports 1-24 SFP ports 1-4 Ruckus ICX 7250-24 RJ-45 ports 1-24 SFP+ ports 1-8 Ruckus ICX 7250-24P RJ-45, PoE/PoE+ ports 1-24 SFP+ ports 1-8 Ruckus ICX 7250-48 RJ-45 ports 1-48 SFP+ ports 1-8 Ruckus 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 congured manually.
SFP or SFP+ ber ports
The Ruckus ICX 7250-24G contains four small form-factor pluggable (SFP) ports (ports 1 through 4). The top row contains odd­numbered 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 Ruckus 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.
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 Ruckus datasheet.

Overview Hardware features
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: Species the stack unit ID. The range is from 1 through the maximum number of devices supported in a stack. Refer to the technical specications for your device for the actual value. If the device is not part of a stack, the stack unit ID is 1.
• slot: Species the slot number; either 1 or 2.
• port: Species 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: Species 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: Species the slot number. Stacking ports are in slot 2.
• port: Species 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

Installing the Universal Four-Post Rack Kit (XBR-R000296)
Use the following instructions to install a device in EIA racks that are between L-12.7 to 81.28 cm deep (L-5.0 to 32.0 in.), where L is the chassis depth, using the Universal Four-Post Rack Kit (XBR-R000296).
There are two ways you can mount the device in a four-post rack:
• With the port side ush with the front posts
• With the nonport side ush with the rear posts in a recessed position
A recessed position allows a more gradual bend in the ber-optic cables connected to the switch and less interference in the aisle at the front of the rack.
NOTE
Although this document describes how to install both single height (1U) and double height (2U) switches, the illustrations show a 1U switch as a typical installation.

Hardware devices illustrated in these procedures are only for reference and may not depict the device you are installing into the rack.
Installation requirements
Provide space in an EIA rack with the following minimum and maximum distances between the front and back posts.
NOTE
For 1U and 2U devices, two people are required to install the device in a rack. One person holds the device, while the other screws in the front and rear "L" brackets.

Note that if chassis depth (L) is less than 40.64 cm (16 in.), the chassis will not t into a rack with a maximum depth of 81.28 cm (32 in.) using the universal four-post rack kit. The maximum rack depth for a chassis less than 40.64 cm (16 in.) is 81.28 cm (32 in.) minus the dierence between the chassis depth and 40.64 cm (16 in.). For example, a chassis with a depth (L) of 35.56 cm (14 in.) is 5.08 cm (2 in.) smaller than 40.64 cm (16 in.), so it will install into a rack with a maximum depth of 81.28 cm (32 in.) - 5.08 cm (2 in.) = 76.2 cm (30 in.).
Review the installation and facility requirements for your product before mounting the device . Refer to the Hardware Installation Guide for your product for more information.
Time and items required
Allow 15 to 30 minutes to complete the installation.
The following items are required to install the device using the Universal Four-Post Rack Kit:

Connecting devices in a traditional stack
ICX 7250 devices can operate as standalone devices and also as members of traditional stacks. A stack is a group of devices— Ruckus stackable units and their connected stacking links—that are connected so that the stack is managed as a single entity.
A traditional stack contains devices from only one model in a product family.

Installation Connecting devices in a traditional stack

Stacking ports and trunks

There are eight SFP+ ports on the front panels of the ICX 7250 devices that support stacking, which can be used as uplink (data) ports or as stacking ports. The following gure shows the ports in slot 2; the top row consists of ports 1, 3, 5, and 7, and the bottom row consists of ports 2, 4, 6, and 8. The numbering for the ports in the following gure is provided in the format x/x/x and refers to StackID/Slot/Port.
FIGURE 40 Stacking ports
Stacking conguration requirements
Before conguring the traditional stack using the CLI, physically connect the devices using stacking cables. For information about conguring a stack, refer to the Ruckus FastIron Stacking Conguration Guide.

Traditional stack size

A traditional stack can contain a maximum of twelve ICX 7250 devices.

Stacking topologies for a traditional stack

Both linear and ring topologies are supported in a traditional stack. In a linear stack topology there is a connection between each switch that carries two-way communications across the stack. The physical connection between the devices can use one port (stacked-port) or two ports (stacked-trunk) per trunk. The stack uses a pair of ports (n, n+1, where n is odd and ranges from 1 through 7) even if there is only one physical connection between the devices in a stack. The physical connections must be from an odd-numbered port to an odd-numbered port or an even-numbered port to an even-numbered port.
NOTE
The examples in the following gures show a 24-port device. The 48-port devices show the same behavior for stacking.

Page 59
Connecting devices in a traditional stack
The following gure shows a linear stacking topology example.
• For the rst device in the stack, ports (1/2/1, 1/2/2) are being used as stacked ports.
• For the second device in the stack, ports (2/2/1, 2/2/2 and 2/2/3, 2/2/4) are being used as stacked ports.
• There is a single physical connection between device 1 and device 2 in the stack, ports 1/2/1 and 2/2/1 (odd-numbered
port to odd-numbered port). This is a stacked-port conguration.
• There are two physical connections between device 2 and device 3 in the stack. Port 2/2/3 is connected to port 3/2/7 (odd-numbered port to odd-numbered port) and port 2/2/4 is connected to 3/2/8 (even-numbered port to even­numbered port). This is a stacked-trunk conguration.
FIGURE 41 Linear stacking topology
Installation
1. First device in stack
2. Second device in stack
3. Third device in stack
In a ring stacking topology, there is an extra connection between the logical rst and last devices, forming a "ring" or "closed­loop." The closed-loop connection provides a redundant path for the stack link, so if one link fails, stack communications can be maintained.

Long-reach multimode adaptor module

Ruckus ICX7150, ICX7250, and ICX7750 Ethernet switches require a long-Reach Multimode (LRM) adaptor module to support LRM optics connections.
The Ruckus LRM adaptor module has two 280 mm Twinax tails and two corresponding SFP+ sockets which operate independently. Power for each of the SFP+ sockets and for the adaptor is provided through the Twinax connections.
The LRM adaptor module requires FastIron software release 08.0.61 or later on the host Ruckus ICX switches. The LRM adaptor module is not eld congurable, rather you can apply all conguration to the host switch port. Use the show lrm-adapter
ethernet command to display the status of the LRM module.

EPS4000 external power supply

In the event of an AC power loss or internal power supply device failure, the Ruckus EPS4000 external power supply can be used as a 12 V, backup power source to a device when any of the DC power supply ports are connected to an ICX 7250 device. The EPS4000 requires a minimum of one RPS17 Power Supply Unit (PSU) to be functional. Proprietary DC cables are used to connect any of the EPS DC ports of the EPS4000 to the rear EPS4000 port of an ICX 7250 device that is supported by the EPS4000. Each RPS17 PSU can provide backup power to one ICX 7250 device. Even though a fully populated EPS4000 can monitor up to sixteen connected devices, the EPS4000 can provide backup power without performance degradation to only four ICX 7250 devices.
NOTE
The primary source of 12 V power for an ICX 7250 device is the internal power supply. The EPS4000 is designed to serve primarily as a backup source of 12 V power. You should service a failed ICX 7250 device as soon as possible after a 12 V power failure is detected.
In case of a 54 V supply failure, the EPS4000 can provide power to multiple devices up to its capacity limit. You can set the system priority for the power budget allocation for this scenario. The default is for the lower-numbered port to have the higher priority. Should a higher priority device have a 54 V supply failure while a lower priority device is already being serviced by the PSU, the power supply will not switch to provide power to the higher priority device to maintain continuity of service. The EPS4000 uses the next PoE-power-budget cycle to reallocate power among the connected ICX 7250 devices.
Ruckus ICX 7250 Switch Hardware Installation Guide Part Number: 53-1003898-08 65
Page 66
Installing the EPS4000 EPS4000 external power supply
In the PoE power extension mode, the EPS4000 can also provide additional power to support the PoE ports as needed. For more information about connecting an ICX 7250 device to the EPS4000, refer to Connecting devices to the external power supply on page 79.
Each RPS17 PSU can provide up to 740 W at 54 V and 120 W at 12 V. The RPS17 draws power from a standard AC source and converts it to DC for use by the switches.
NOTE
The internal power supply of the ICX 7250 devices is not a eld-replaceable unit (FRU). The devices must be shut down by administrators for replacement.
Ruckus recommends that you pay attention to the PoE or PoE+ port conguration of the device when connecting to an EPS4000. The internal power supply of each PoE or PoE+ device has a maximum number of supported PoE or PoE+ ports. Ruckus recommends that when the EPS4000 is used as a redundant power source for the PoE device, that the maximum number of PoE or PoE+ ports of the external power supply must not exceed the maximum number of PoE or PoE+ ports of the internal power supply capability of each device.
The following devices are supported by the Ruckus EPS4000:
• ICX 7250-24
• ICX 7250-24P
• ICX 7250-48
• ICX 7250-48P
NOTE
The ICX 7250-24G is not supported by the EPS4000.

PC or terminal attachment

You can access the CLI by attaching a serial cable to the console port. After you assign an IP address, you can access the system through Telnet or Brocade Network Advisor.
Ruckus ICX 7250 Switch Hardware Installation Guide Part Number: 53-1003898-08 83
Page 84
Conguring the Device Password assignment
Complete the following steps to attach a management station to the console port.
1. Connect a PC or terminal to the console (mini-USB) port of the device.
To connect the console port to a DB9 port, you need a cable with mini-USB and DB9 connectors.
For information about locating the serial port, refer to Network and management interfaces on page 14.
The serial port has a mini-USB connector. For port pinout information, refer to Ruckus ICX 7250 Switch Technical
Specications on page 95.
NOTE
You must run a terminal emulation program on the PC.
2. Launch the terminal emulation program and set the following session parameters:
• Baud: 9600 bps
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
The console serial communication port serves as a connection point for management by a PC or SNMP workstation. When you establish the serial connection to the system, press Enter to display the CLI prompt in the terminal emulation window, as shown in the following example.
device>
If you see this prompt, you are connected to the system and can proceed to Password assignment on page 84.
You can customize the prompt by changing the system name. For more information, refer to the Ruckus FastIron Management Conguration Guide.
If you do not see the prompt, make sure the cable is securely connected to your PC and to the Ruckus device.
Check the settings in your terminal emulation program. In addition to the previously congured session settings, make sure the terminal emulation session is running on the same serial port you attached to the Ruckus device.

Password assignment

By default, the CLI is not protected by passwords. To secure CLI access, Ruckus strongly recommends assigning passwords. Refer to the FastIron Ethernet Switch Administration Guide.
NOTE
You can assign passwords using Brocade Network Advisor if an enable password for a Super User has been congured on the device.
The CLI contains the following access levels:
• User EXEC: The level you enter when you rst start a CLI session. At this level, you can view some system information but you cannot congure system or port parameters.
• Privileged EXEC: This level is also called the Enable level and can be secured by a password. You can perform tasks such as managing les on the ash module, saving the system conguration to ash, and clearing caches at this level.
• CONFIG: The conguration level. This level allows you to congure the system IP address and congure switching and routing features. To access the CONFIG mode, you must already be logged in to the privileged EXEC level.

Ruckus ICX 7250 Switch Hardware Installation Guide
Page 85
Conguring the Device
Password assignment
You can set the following levels of Enable passwords:
• Super User: Allows complete read-and-write access to the system. This is generally for system administrators and is the only password level that allows you to congure passwords.
NOTE
You must set a Super User password before you can set other types of passwords.
• Port Conguration: Allows read-and-write access for specic ports but not for global (system-wide) parameters.
• Read-Only: Allows access to the privileged EXEC mode and CONFIG mode but only with read access.

Assigning passwords

Complete the following steps to set passwords.
NOTE
Depending on the device you purchased, and the code (Layer 2 or Layer 3) loaded on your system, the router prompt is displayed accordingly. For example, for an ICX 7250-48P device running Layer 3 code on the device, the router prompt displays ICX 7250-48P Router> at the CLI level.
1. At the opening CLI prompt, enter the following command to change to the Privileged EXEC mode:
device> enable
2. Access the conguration mode of the CLI by entering the following command:
device# configure terminal
3. Enter the following command to set the Super User password:
device(config)# enable super-user-password joe
NOTE
You must set the Super User password before you can set other types of passwords.
4. Enter the following commands to set the port conguration and read-only passwords:
device(config)# enable port-config-password john device(config)# enable read-only-password sam
NOTE
If you forget your Super User password, refer to Recovering from a lost password on page 85.
Passwords can be up to 32 characters long.

Recovering from a lost password

By default, the CLI does not require passwords. However, if a password has been congured for the device but the password has been lost, you can regain Super User access to the device using the following procedure.
NOTE
Recovery from a lost password requires direct access to the serial port and a system reset.
1. Start a CLI session over the serial interface to the Ruckus device.
2. Reboot the device.

Conguring the Device IP address conguration
3. While the system is booting, before the initial system prompt appears, enter b to enter the boot monitor mode.
4. Enter no password. (You cannot abbreviate this command.)
5. Enter boot. This command causes the device to bypass the system password check.
After the console prompt reappears, assign a new password.
IP address conguration
You must congure at least one IP address using the serial connection to the CLI before you can manage the system using the other management interfaces.
Ruckus devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Interdomain Routing (CIDR) network prex masks.
• To enter a classical IP network mask, enter the mask in IP address format. For example, enter "10.157.22.99
255.255.255.0" for an IP address with a Class C subnet mask.
• To enter a prex number for a network mask, enter a forward slash (/) and the number of bits in the mask immediately after the IP address. For example, enter "10.157.22.99/24" for an IP address that has a network mask with 24 signicant ("mask") bits.
By default, the CLI displays network masks in classical IP address format (for example, 255.255.255.0). You can change the display to the prex format. Refer to the FastIron Ethernet Switch Administration Guide.

Devices running Layer 2 software

Use the following procedure to congure an IP address on a device running Layer 2 software.
1. At the opening CLI prompt, enter enable.
device> enable
2. Enter the following command at the Privileged EXEC level prompt, and then press Enter . This command erases the factory test conguration if still present.
device# erase startup-config
CAUTION Use the erase startup-cong command only for new systems. If you enter this command on a system you have already congured, the command erases the conguration. If you accidentally do erase the
conguration on a congured system, enter the write memory command to save the running conguration to the startup-cong le.
3. Access the global conguration level of the CLI by entering the following command:
device# configure terminal
4. Congure the IP address and mask for the device.
device(config)# ip address 10.22.3.44 255.255.255.0

IP address conguration
5. Set a default gateway address for the device.
device(config)# ip default-gateway 10.22.3.1
NOTE
You do not need to assign a default gateway address for single subnet networks.

Devices running Layer 3 software

Before attaching equipment to a Ruckus ICX device running Layer 3 software, you must assign an interface IP address to the subnet on which the device will be located. You must use the serial connection to assign the rst IP address. For subsequent addresses, you also can use the CLI through Telnet.
By default, you can congure up to 24 IP interfaces on each port, virtual interface, and loopback interface. You can increase this amount to up to 64 IP subnet addresses per port by increasing the size of the subnet-per-interface table.
The following procedure shows how to add an IP address and mask to a router port.
1. At the opening CLI prompt, enter enable.
device> enable
2. Enter the following command at the privileged EXEC level prompt, and then press Enter . This command erases the factory test conguration if still present.
device# erase startup-config
CAUTION Use the erase startup-cong command only for new systems. If you enter this command on a system you have already congured, the command erases the conguration. If you accidentally do erase the
conguration on a congured system, enter the write memory command to save the running conguration to the startup-cong le.
3. Access the global conguration level of the CLI by entering the following command.
device# configure terminal device(config)#
4. Congure the IP addresses and mask addresses for the interfaces on the router.
device(config)# interface ethernet 2 device(config)# ip address 10.22.3.44 255.255.255.0
NOTE
You can use the ip address ip-addr/mask-bits command if you know the subnet mask length. In the previous example, you could enter ip address 10.22.3.44/24.
Use the secondary option of the ip address command parameter if you have already congured an IP address within the same subnet on the interface.
Conguring IP parameters for devices running Layer 3 software
You must congure IP parameters for devices running Layer 3 software.
Ruckus ICX 7250 Switch Hardware Installation Guide Part Number: 53-1003898-08 87
Page 88
Conguring the Device IP address conguration
Conguring IP addresses
You can congure an IP address on the following types of Layer 3 interfaces:
• Ethernet port
• Virtual routing interface (also called a Virtual Ethernet or "VE")
• Loopback interface
By default, you can have up to 24 IP addresses on each interface, but you can increase this number to 128 IP addresses.
NOTE
Once you congure a virtual routing interface on a VLAN, you cannot congure Layer 3 interface parameters on individual ports in the VLAN. Instead, you must congure the parameters on the virtual routing interface itself.
Assigning an IP address to an Ethernet port
Enter the following commands to assign an IP address to port 1/1/1.
device(config)# interface ethernet 1/1/1 device(config)# ip address 10.45.6.1 255.255.255.0
You also can enter the IP address and mask in CIDR format.
device># ip address 10.45.6.1/24
Assigning an IP address to a loopback interface
Loopback interfaces are always up, regardless of the states of physical interfaces. They can add stability to the network because they are not subject to route ap problems that can occur due to unstable links between a Layer 3 device and other devices. You can congure up to four loopback interfaces on a Layer 3 device.
You can add up to 24 IP addresses to each loopback interface.
NOTE
If you congure the device to use a loopback interface to communicate with a BGP4 neighbor, you must also congure a loopback interface on the neighbor and congure the neighbor to use that loopback interface to communicate with the Ruckus device.
To add a loopback interface, enter the interface loopback num and ip address num commands similar to the following example.
device(config)# exit device(config)# interface loopback 1 device(config)# ip address 10.0.0.1/24
You can specify from 1 through the maximum number of virtual interfaces supported on the device by using the interface loopback num command.. To display the maximum number of virtual interfaces supported on the device, enter the show default values command.
Assigning an IP address to a virtual routing interface
A virtual interface is a logical port associated with a Layer 3 Virtual LAN (VLAN) congured on a Layer 3 device. You can congure routing parameters on the virtual interface to enable the Layer 3 device to route protocol trac from one Layer 3 VLAN to the other, without using an external router.

Conguring the Device

Connecting network devices

NOTE
The device uses the lowest MAC address on the device (the MAC address of port 1 or 1/1/1) as the MAC address for all ports within all virtual interfaces you congure on the device.
Enter commands similar to the following to add a virtual interface to a VLAN and congure an IP address on the interface.
device(config)# vlan 2 name IP-Subnet_10.1.2.1/24 device(config-vlan-2)# untag 1/1/1 to 1/1/4 device(config-vlan-2)# router-interface ve1 device(config-vlan-2)# interface ve1 device(config-vif-1)# ip address 10.1.2.1/24
The rst two commands in this example create a Layer 3 protocol-based VLAN named "IP-Subnet_10.1.2.1/24" and add a range of untagged ports to the VLAN. The router-interface command creates virtual interface 1 as the routing interface for the VLAN. The last two commands change to the interface conguration level for the virtual interface and assign an IP address to the interface.
Deleting an IP address
Enter a command similar to the following to delete an IP address.
device(config-if-1/1/1)# no ip address 10.1.2.1
This command deletes IP address 10.1.2.1. You do not need to enter the subnet mask.
To delete all IP addresses from an interface, enter the following command.
device(config-if-1/1/1)# no ip address *
Connecting network devices
Ruckus devices support connections to other vendors’ routers, switches, and hubs, as well other Ruckus devices.

Connectors

For port pinouts, refer to Ruckus ICX 7250 Switch Technical Specications on page 95.
Cable specications
For information about supported transceivers and cable lengths and types, refer to the Ruckus optics family datasheet.

Connecting to Ethernet or Fast Ethernet hubs

For copper connections to Ethernet hubs, a 10/100Base-TX or 1000Base-T switch, or another Ruckus device, a crossover cable is required as shown in the following gure. If the hub is equipped with an uplink port, it requires a straight-through cable instead of a crossover cable.
NOTE
The 802.3ab standard (automatic MDI or MDIX detection) calls for automatic negotiation of the connection between two 1000Base-T ports. In this case, a straight-through cable may work just as well as a crossover cable. For more information, refer to the FastIron Ethernet Switch Administration Guide.

Troubleshooting network connections

Automatic MDI or MDIX detection
All 10/100 and 1000 Mbps Ethernet copper ports on the devices support automatic Media Dependent Interface (auto-MDI) or automatic Media Dependent Interface Crossover (auto-MDIX) detection. Auto-MDI or auto-MDIX is enabled on all 10/100 and 1000 Mbps copper ports by default. For each port, you can disable auto-MDI or auto-MDIX, designate the port as an MDI port, or designate the port as an MDIX port.
For more information about this feature and how to congure it, refer to the FastIron Ethernet Switch Administration Guide.
Connecting a network device to a ber port
For direct attachment from the device to a Gigabit NIC, switch, or router, using a ber-optic transceiver, you need ber cabling with an LC connector.
To connect the device to another network device using a ber port, you must perform the following tasks:
• Install a ber-optic transceiver (SFP or SFP+).
• Cable the ber-optic transceiver.
For instructions on installing ber-optic transceivers, refer to Installing a ber-optic transceiver on page 110.
For instructions on cabling a ber-optic transceiver, refer to Cabling a ber-optic transceiver on page 111.
For instructions on cleaning a ber-optic module, refer to Cleaning the ber-optic connectors on page 112.
Troubleshooting network connections
• For the indicated port, verify that both ends of the cabling (at the device and the connected device) are snug.
• Verify that the device and the connected device are both powered on and operating correctly.
• Verify that you have used the correct cable type for the connection: – For twisted-pair connections to an end node, use straight-through cabling.
– For ber-optic connections, verify that the transmit port on the device is connected to the receive port on the
connected device, and that the receive port on the device is connected to the transmit port on the connected device.
• Use the CLI to verify that the port has not been disabled through a conguration change. If you have congured an IP address on the device, you also can use Brocade Network Advisor.
• If the other procedures do not resolve the problem, try using a dierent port or a dierent cable.
• If a 1-Gbps optic transceiver is inserted into an ICX 7250 device, you must congure the port using the speed-duplex 1000-full-master command at the interface level.

Digital optical monitoring

NOTE
10 Gbps optical transceivers are not supported on ICX 7250-24G devices.
You can congure your device to monitor optical transceivers in the system, either globally or by specied port. When this feature is enabled, the system monitors the temperature and signal power levels for the optical transceivers in the specied ports. Console messages and syslog messages are sent when optical operating conditions fall below or rise above the SFP and SFP+ manufacturer’s recommended thresholds. For more information about digital optical monitoring, refer to the FastIron Ethernet Switch Administration Guide.
