Brocade ICX 7250 Switch Hardware Installation Guide 15 53-1003622-02

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 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:

16 Brocade ICX 7250 Switch Hardware Installation Guide

53-1003622-02

Specifying a management 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.

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.

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.

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.

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—Brocade 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.

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 figure below 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.

Brocade ICX 7250 Switch Hardware Installation Guide 31 53-1003622-02

Stacking configuration requirements

FIGURE 16 Stacking ports

1. Slot 2 (SFP+ uplink or stacking ports) - StackID/Slot/Port

Stacking configuration requirements

Before configuring the traditional stack using the CLI, physically connect the devices using stacking cables. For information about configuring a stack, refer to the FastIron Ethernet Switch Stacking Configuration Guide.

Traditional stack size

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

Stacking topologies for 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.

The following section discusses examples of supported stacking topologies.

NOTE

The figures in the examples show a 24-port device. The 48-port devices show the same behavior for stacking.

The following figure shows a linear stacking topology example.

32 Brocade ICX 7250 Switch Hardware Installation Guide

53-1003622-02

Powering on the system

• For the first 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. This is a stacked-port configuration, odd-numbered port to odd-numbered port.

• 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 even-numbered port. This is a stacked-trunk configuration.

FIGURE 17 Linear stacking topology

1. First device in stack

2. Second device in stack

3. Third device in stack

In ring stack topology, there is an extra connection between the logical first and last devices forming a "ring" or "closed-loop." The closed-loop connection provides a redundant path for the stack link, so if one link fails, stack communications can be maintained.

Before beginning the installation, see the precautions in “Power precautions.”

DANGER

Be careful not to accidently insert your fingers into the fan tray while removing it from the chassis. The fan may still be spinning at a high speed.

EPS4000 external power supply

In the event of an AC power loss or internal power supply device failure, the Brocade 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

Brocade ICX 7250 Switch Hardware Installation Guide 53-1003622-02

Features and benefits

the lower number 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 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.

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 49.

Each RPS17 PSU can provide up to 720 W at 54 Volts and 120 W at 12 Volts. 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 field-replaceable unit (FRU). The devices must be shut down by administrators for replacement.

Brocade recommends that you pay attention to the PoE or PoE+ port configuration 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. Brocade 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 Brocade EPS4000:

• ICX 7250-24

• ICX 7250-24P

• ICX 7250-48

• ICX 7250-48P

NOTE

The ICX 7250-24G is not supported by the EPS4000.

Features and benefits

• Hosts up to four hot-swappable RPS17 power supply units (PSUs).

• Provides N:1 power redundancy at 12 V with each PSU.

• Each RPS17 can deliver a maximum of 720 W at 54 Volts and 120 W at 12 Volts.

• A fully populated EPS4000 has 8 DC power ports that can monitor up to 16 switches simultaneously and provide 12-V redundant power to four switches.

• Provides power redundancy at 54 Volts and true extended PoE power support.

• 1:1 and 1:2 cables support 54 V or 12 V distribution up to 1 meter.

• Status LEDs are located on the front panel.

• Universal (100 - 240 V) AC line cord draws power from standard power outlet.

• The EPS4000 firmware is field-upgradeable.

• The power to the switches is maintained while the microcontroller unit (MCU) is being reset.

• The power distribution to the connected switches can be controlled per a priority scheme that you set.

Front and rear panels

There are thirty two LEDs on the front panel of the EPS4000 to indicate the status for the DC power on the 8 ports. Sixteen (Ex.x) are for the 54-V DC and the other sixteen (Rx.x) are for the 12-V DC

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.

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 DB-9 port, you need a cable with mini-USB and DB-9 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 Brocade ICX 7250

Switch Technical Specifications on page 73.

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 the task Password

assignment on page 54.

You can customize the prompt by changing the system name. For more information, refer to the FastIron Ethernet Switch Administration Guide.

If you do not see the prompt, make sure the cable is securely connected to your PC and to the Brocade system.

Check the settings in your terminal emulation program. In addition to the previously configured session settings, make sure the terminal emulation session is running on the same serial port you attached to the Brocade system.

Password assignment

By default, the CLI is not protected by passwords. To secure CLI access, Brocade 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 configured on the device.

54 Brocade ICX 7250 Switch Hardware Installation Guide

53-1003622-02

Assigning passwords

The CLI contains the following access levels:

• User EXEC - The level you enter when you first start a CLI session. At this level, you can view some system information but you cannot configure 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 files on the flash module, saving the system configuration to flash, and clearing caches at this level.

• CONFIG - The configuration level. This level allows you to configure the system IP address and configure switching and routing features. To access the CONFIG mode, you must already be logged in to the Privileged EXEC level.

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 configure passwords.

NOTE

You must set a Super User password before you can set other types of passwords.

• Port Configuration - Allows read-and-write access for specific 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 config 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 configuration 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 the Recovering from a lost password on page 56 task.

Brocade ICX 7250 Switch Hardware Installation Guide 55 53-1003622-02

Recovering from a lost password

Syntax: enable { super-user-password | read-only-password | port-config-password} text

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 configured 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 Brocade device.

2. Reboot the device.

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.

Syntax: [no] password

Syntax: boot

IP address configuration

You must configure at least one IP address using the serial connection to the CLI before you can manage the system using the other management interfaces.

Brocade devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Interdomain Routing (CIDR) network prefix 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 prefix 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 significant ("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 prefix format. Refer to the FastIron Ethernet Switch

Administration Guide.

Devices running Layer 2 software

Use the following procedure to configure an IP address on a device running Layer 2 software.

56 Brocade ICX 7250 Switch Hardware Installation Guide

53-1003622-02

Devices running Layer 3 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 configuration if still present.

device# erase startup-config

CAUTION

Use the erase startup-config command only for new systems. If you enter this command on a system you have already configured, the command erases the configuration. If you accidentally do erase the configuration on a configured system, enter the write memory command to save the running configuration to the startup-config file.

3. Access the global configuration level of the CLI by entering the following command:

device# configure terminal device(config)#

4. Configure the IP address and mask for the device.

device(config)# ip address 10.22.3.44 255.255.255.0

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.

Syntax: [no] ip address { ip-addr ip-mask | ip-addr/mask-bits }

Syntax: [no] ip default-gateway ip-addr

Devices running Layer 3 software

Before attaching equipment to a Brocade 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 first IP address. For subsequent addresses, you also can use the CLI through Telnet.

By default, you can configure 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 CLI Privileged EXEC level prompt, and then press Enter . This command erases the factory test configuration if still present.

device# erase startup-config

CAUTION

Brocade ICX 7250 Switch Hardware Installation Guide 57 53-1003622-02

Configuring IP parameters for devices running Layer 3 software

3. Access the global configuration level of the CLI by entering the following command.

device# configure terminal Brocade(config)#

4. Configure 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 example in step 4, you could enter ip address 10.22.3.44/24.

Syntax: [no] ip address { ip-addr ip-mask [ secondary ] | ip-addr/mask-bits [ secondary ] }

Use the secondary parameter if you have already configured an IP address within the same subnet on the interface.

Configuring IP parameters for devices running Layer 3 software

This section describes how to configure IP parameters for devices running Layer 3 software.

Configuring IP addresses

You can configure 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 configure a virtual routing interface on a VLAN, you cannot configure Layer 3 interface parameters on individual ports in the VLAN. Instead, you must configure 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.

Brocade(config)# interface ethernet 1/1/1 Brocade(config)# ip address 10.45.6.1 255.255.255.0

You also can enter the IP address and mask in CIDR format, as follows:

Brocade># ip address 10.45.6.1/24

Syntax: [no] ip address { ip-addr ip-mask | ip-addr/mask-bits }

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 flap problems that can occur due to

58 Brocade ICX 7250 Switch Hardware Installation Guide

53-1003622-02

Deleting an IP address

unstable links between a Layer 3 device and other devices. You can configure 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 configure the device to use a loopback interface to communicate with a BGP4 neighbor, you must also configure a loopback interface on the neighbor and configure the neighbor to use that loopback interface to communicate with the Brocade device.

To add a loopback interface, enter commands such as those shown in the following example:

Brocade(config)# exit Brocade(config)# interface loopback 1 Brocade(config)# ip address

10.0.0.1/24

Syntax: interface loopback num

The num parameter specifies the virtual interface number. You can specify from 1 through the maximum number of virtual interfaces supported on the device. 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) configured on a Layer 3 device. You can configure routing parameters on the virtual interface to enable the Layer 3 device to route protocol traffic from one Layer 3 VLAN to the other, without using an external router.

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 configure on the device.

Enter commands similar to the following to add a virtual interface to a VLAN and configure an IP address on the interface.

Brocade(config)# vlan 2 name IP-Subnet_10.1.2.1/24 Brocade(config-vlan-2)# untag 1/1/1 to 1/1/4 Brocade(config-vlan-2)# router-interface ve1 Brocade(config-vlan-2)# interface ve1 Brocade(config-vif-1)# ip address 10.1.2.1/24

The first two commands in this example create a Layer 3 protocol-based VLAN named "IPSubnet_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 configuration level for the virtual interface and assign an IP address to the interface.

Syntax: router-interface ve num

Syntax: interface ve num

Deleting an IP address

Enter a command similar to the following to delete an IP address.

Brocade(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.

Brocade ICX 7250 Switch Hardware Installation Guide 59 53-1003622-02

Connecting network devices

To delete all IP addresses from an interface, enter the following command.

Brocade(config-if-1/1/1)# no ip address *

Syntax: [no] ip address { ip-addr | * }

Connecting network devices

Brocade devices support connections to other vendors’ routers, switches, and hubs, as well other Brocade devices.

Connectors

For port pinouts, refer to Brocade ICX 7250 Switch Technical Specifications on page 73.

Cable specifications

For information about supported transceivers and cable lengths and types, refer to the Brocade 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 Brocade device, a crossover cable is required (see the figures below). 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 about this feature, refer to the FastIron Ethernet Switch

Security Configuration Guide.

• 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 fiber-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 configuration change. If you have configured 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 different port or a different cable.

• If a 1-Gbps optic transceiver is inserted into a ICX 7250 device, you must configure 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 configure your device to monitor optical transceivers in the system, either globally or by specified port. When this feature is enabled, the system monitors the temperature and signal power levels for the optical transceivers in the specified 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

The procedures in this manual are for qualified service personnel.

Managing temperature settings

The device contains temperature sensors that the software reads based on a configurable device poll time. The devices have two automatic speed fan control settings based on the temperature. To protect the device from overheating, the following temperature threshold levels exist:

• The warning level is the temperature at which the device generates a syslog message. It is configurable up to 100°C.

• The shutdown level is the temperature at which the device reboots. It is set by the device and is not configurable. When the device temperature reaches the shutdown level, it generates a warning message that the device’s temperature is over the shutdown level and the device will shut down in five minutes. The system restarts five minutes after the device reaches the temperature shutdown level.

Changing the temperature warning level

To change the temperature at which the device sends a syslog message and an SNMP trap, enter a command similar to the following at the Privileged EXEC level of the CLI.

Brocade# temperature warning 1 82

Syntax: temperature warning stack-idvalue

The stack-id can be a value from 1 through 12.

The value variable is the temperature warning level, in Celsius. You cannot set this level higher than the maximum value allowed by your device. The temperature warning level must be at least five Celsius degrees less than the temperature shutdown level, which is automatically set by the device.

The following console and syslog message is displayed when the temperature reaches the warning level:

!!! Temperature is over warning level on stack unit 1!!!

Temperature shutdown levels

When the temperature crosses the critical (shutdown) threshold levels, the device will reset after 5 minutes. The following console and syslog message is displayed:

!!! Temperature is over shutdown level, please shutdown your stack unit 1 to avoid hw damage!!!

NOTE

Brocade recommends that you shut down your stack unit to avoid any hardware damage.

Changing the temperature poll time

By default, the software polls the temperature sensor every 60 seconds to get the current temperature. This poll rate is controlled by the device poll time, which also controls how often the software polls other system components.

Brocade ICX 7250 Switch Hardware Installation Guide 67 53-1003622-02

Displaying CPU usage

To change the poll time, enter a command similar to the following at the global CONFIG level.

Brocade(config)# chassis poll-time 200

Syntax: chassis poll-time value

The value variable can be from 0 through 65535 seconds.

Displaying CPU usage

You can display the amount of the CPU in use. To do so, enter the show cpu command at any level of the CLI.

Brocade# show cpu

20 percent busy, from 318 sec ago 1 sec avg: 2 percent busy 5 sec avg: 1 percent busy 60 sec avg: 1 percent busy 300 sec avg: 1 percent busy

Syntax: show cpu

Removing MAC address entries

You can remove the following types of learned MAC address entries from the system MAC address table:

• All MAC address entries

• All MAC address entries for a specified Ethernet port

• All MAC address entries for a specified VLAN

• A specified MAC address entry in all VLANs

For example, to remove entries for the MAC address 00-00-00 in all VLANs, enter the following command at the Privileged EXEC level of the CLI.

Brocade# clear mac-address 00-00-00

Syntax: clear mac-address [ mac-address | ethernet port-num | vlan number ]

If you enter the clear mac-address command without any parameters, the software removes all MAC entries.

Use the mac-address variable to remove a specified MAC address from all VLANs. Specify the MAC address in the following format: HHHH.HHHH.HHHH.

Use the ethernet port-num parameter to remove all MAC addresses for a specified Ethernet port.

Use the vlan number parameter to remove all MAC addresses for a specified VLAN.

Hardware maintenance schedule

● Copper or fiber-optic module replacement......................................................................69

DANGER

The procedures in this manual are for qualified service personnel.

The ICX 7250 devices require minimal maintenance for their hardware components. However, Brocade recommends cleaning the fiber-optic connectors on a fiber-optic port and the connected fiber cable each time you disconnect the cable.

Copper or fiber-optic module replacement

You can replace the copper and fiber-optic modules (SFP and SFP+ transceivers). You can remove an SFP or an SFP+ transceiver from a slot and replace it with a new one while the ICX 7250 device is powered on and running.

Removing a copper or fiber-optic module

You can remove a copper or fiber SFP or SFP+ transceiver from a slot while the ICX 7250 device is powered on and running.

While removing a copper or fiber-optic module, be sure to wear an ESD wrist strap with a plug that can be inserted in the ESD connector on the ICX 7250 device.

DANGER

For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.

To remove a copper or fiber-optic module from an SFP or SFP+ slot, do the following.

1. Put on the ESD wrist strap and ground yourself by attaching the clip end to a metal surface (such as an equipment rack).

2. Disconnect the copper or fiber cable connector from the port connector.

3. Unlock the copper or fiber-optic module by pulling the bail latch forward, away from the front panel of the module. This unlocks the module from the front panel.

NOTE

On 1000Base-SX ports, the bail latch is enclosed in a black sleeve, and on 1000Base-LX ports, the bail latch is enclosed in a blue sleeve.

NOTE

The bail latch may be attached to either the top or the bottom of the SFP transceiver.

4. Grasp the bail latch and pull the copper or fiber-optic module out of the port.

FIGURE 32 Removing the fiber-optic module

5. Store the copper or fiber-optic module in a safe, static-free place or in an anti-static bag.

6. Install a new copper or fiber-optic module in the port.

Installing a fiber-optic transceiver

You can install a new fiber-optic transceiver in an SFP or SFP+ slot while the device is powered on and running.

While installing a transceiver, wear an ESD wrist strap with a plug that can be inserted in the ESD connector on the ICX 7250 device.

DANGER

For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.

DANGER

All fiber-optic interfaces use Class 1 lasers.

Perform the following steps to install a fiber-optic transceiver.

70 Brocade ICX 7250 Switch Hardware Installation Guide

53-1003622-02

Cabling a fiber-optic transceiver

1. Put on the ESD wrist strap and ground yourself by attaching the clip end to a metal surface (such as an equipment rack) to act as ground.

2. Remove the new transceiver from the protective packaging.

3. Gently insert the transceiver into the slot until it clicks into place. Transceivers are keyed to prevent incorrect insertion.

Cabling a fiber-optic transceiver

Perform the following steps to cable a fiber-optic transceiver.

1. Remove the protective covering from the fiber-optic port connectors and store the covering for future use.

NOTE

Before cabling a fiber-optic transceiver, Brocade strongly recommends cleaning the cable connectors and the port connectors.

2. Gently insert the cable connector (a tab on each connector should face upward) into the transceiver connector until the tabs lock into place.

3. Observe the link and active LEDs to determine if the network connections are functioning properly. For more information about the LED indicators, refer to Observing LEDs on page 63.

Brocade ICX 7250 Switch Hardware Installation Guide 71 53-1003622-02

Cleaning the fiber-optic connectors

To avoid problems with the connection between the fiber-optic transceiver (SFP or SFP+) and the fiber cable connectors, Brocade strongly recommends cleaning both connectors each time you disconnect and reconnect them. Dust can accumulate in the connectors and cause problems, such as reducing the optic launch power.

To clean the fiber cable connectors, Brocade recommends using a fiber-optic reel-type cleaner. When not using an SFP or SFP+ connector, make sure to keep the protective covering in place.

Symptom Action

Power LED is Off • Check if internal power supply is disconnected.

• Check connections between the device, the power cord, and the wall outlet.

• Contact Technical Support.

Power LED is Amber Internal power supply has failed. Contact Technical Support.

Diag LED is Amber • The device self test has detected a fault.

• Power cycle the device to try and clear the condition. If the condition persists, contact Technical Support.

Link LED is Off • Verify that the device and attached device are powered on.

• Be sure the cable is plugged into both the device and the corresponding device.

• Verify that the proper cable type is used and its length does not exceed specified limits.

• Check the adapter on the attached device and cable connections for possible defects. Replace the defective adapter or cable if necessary.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

Power and cooling problems

If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and use the show chassis command to verify that the temperature is below the shutdown threshold. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, contact Technical Support for assistance.

Brocade ICX 7250 Switch Hardware Installation Guide 53-1003622-02

In-band access

You can access the management agent in the device from anywhere within the attached network using Telnet, or other network management software. However, you must first configure the device with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address. Also, be sure the port through which you are connecting to the device has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the device.
