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 Specications on page 91 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
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 congured manually.
SFP or SFP+ ber ports
The Brocade 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 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.
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: Species the stack unit ID. The range is from 1 through the maximum number of devices supported in a stack. Refer
to the technical specications for your device for the actual value. If the device is not part of a stack, the stack unit ID is 1.
•slot: Species the slot number; either 1 or 2.
•port: Species 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:
devices (units) that can be supported in the stack.
•slot: Species the slot number. Stacking ports are in slot 2.
•port: Species the port number in the slot.
Species the stack unit ID. For models that support stacking, the range is from 1 through the maximum number of
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

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 gure shows an example of a typical rear panel for an ICX 7250 device.
FIGURE 10 ICX 7250 power supply connectors
1.External power supply (EPS4000) connector
2.AC power supply socket
NOTE
The power connector for the EPS4000 is typically covered with a lid that is screwed on as shown in the following gure. To
ensure proper device cooling, keep the connector covered when not in use.
1.Fan
2.External power supply (EPS4000) connector with cover on
Depending on the conguration, each EPS4000 connection from the device to the EPS4000 can add 24 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 370 W (or 740 W), the device can support 24 (or 48) PoE ports. The
system power (12-volt supply) portion of the EPS4000 can be used for internal system power redundancy.

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
dierence 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.).

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.
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 conguration requirements
Before conguring the traditional stack using the CLI, physically connect the devices using stacking cables. For information about
conguring a stack, refer to the Brocade FastIron Stacking Conguration 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 oddnumbered port or an even-numbered port to an even-numbered port.

Connecting devices in a traditional stack
NOTE
The examples in the following gures show a 24-port device. The 48-port devices show the same behavior for
stacking.
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 conguration.
•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 (oddnumbered 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 conguration.
FIGURE 41 Linear stacking topology
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 "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 ngers 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 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-powerbudget cycle to reallocate power among the connected ICX 7250 devices.
Brocade ICX 7250 Switch Hardware Installation Guide
Part Number: 53-1003898-0561
Page 62
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
75.
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.
Brocade recommends that you pay attention to the PoE or PoE+ port conguration 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.

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 Brocade ICX 7250 Switch Technical
Specications on page 91.
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 80.
You can customize the prompt by changing the system name. For more information, refer to the FastIron Ethernet SwitchAdministration 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 congured 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 congured 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 congure 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 conguration to ash, and clearing caches at this level.
•CONFIG: The conguration level. This level allows you to congure the system IP address and congure 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 congure passwords.
NOTE
You must set a Super User password before you can set other types of passwords.
•Port Conguration: Allows read-and-write access for specic 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(config)# enable super-user-password joe
NOTE
You must set the Super User password before you can set other types of 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 81.
Recovering from a lost password
By default, the CLI does not require passwords. However, if a password has been
lost, you can regain Super User access to the device using the following procedure.

IP address conguration
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 conguration
You must congure 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 prex 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 prex 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 signicant ("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
prex format. Refer to the FastIron Ethernet Switch Administration Guide.
the
Devices running Layer 2 software
Use the following procedure to congure 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
conguration if still present.
device# erase startup-config
CAUTION
Use the erase startup-cong command only for new systems. If you enter this command on a system you have
already congured, the command erases the conguration. If you accidentally do erase the conguration on a
congured system, enter the write memory command to save the running conguration to the startup-congle.
3.Access the global conguration level of the CLI by entering the following command:
device# configure terminal
4.Congure 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.
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 rst IP address. For subsequent addresses, you also
can use the CLI through Telnet.
By default, you can congure 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
conguration if still present.
device# erase startup-config
CAUTION
Use the erase startup-cong command only for new systems. If you enter this command on a system you have
already congured, the command erases the conguration. If you accidentally do erase the conguration on a
congured system, enter the write memory command to save the running conguration to the startup-congle.
3.Access the global conguration level of the CLI by entering the following command.
device# configure terminal
Brocade(config)#
4.Congure 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 addressip-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 congured an IP address within the same
subnet on the interface.
Conguring IP parameters for devices running Layer 3 software
You must
Conguring IP addresses
You can congure an IP address on the following types of Layer 3 interfaces:
congure IP parameters for devices running Layer 3 software.
•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.
Brocade ICX 7250 Switch Hardware Installation Guide
Part Number: 53-1003898-0583
Page 84
IP address conguration
NOTE
Once you congure a virtual routing interface on a VLAN, you cannot congure Layer 3 interface parameters on individual
ports in the VLAN. Instead, you must congure 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
to four loopback interfaces on a Layer 3 device.
You can add up to 24 IP addresses to each loopback interface.
ap problems that can occur due to unstable links between a Layer 3 device and other devices. You can congure up
NOTE
If you congure the device to use a loopback interface to communicate with a BGP4 neighbor, you must also congure a
loopback interface on the neighbor and congure the neighbor to use that loopback interface to communicate with the Brocade
device.
To add a loopback interface, enter the interface loopbacknum and ip addressnum 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 loopbacknum 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) congured on a Layer 3 device. You can congure
routing parameters on the virtual interface to enable the Layer 3 device to route protocol trac 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 congure on the device.
Enter commands similar to the following to add a virtual interface to a VLAN and congure 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 conguration 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 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 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.

Straight-through UTP cabling is required for direct UTP attachment to workstations, servers, or routers using network interface cards
(NICs).
Fiber cabling is required for direct attachment to Gigabit NICs or switches and routers through ber ports. Refer to Connecting a network
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 congure 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 106.
For instructions on cabling a ber-optic transceiver, refer to Cabling a ber-optic transceiver on page 107.
For instructions on cleaning a
ber-optic module, refer to Cleaning the ber-optic connectors on page 108.
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
•Use the CLI to verify that the port has not been disabled through a conguration change. If you have congured 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 dierent port or a dierent cable.
•If a 1-Gbps optic transceiver is inserted into an ICX 7250 device, you must congure the port using the speed-duplex 1000-
full-master command at the interface level.

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.
You can congure your device to monitor optical transceivers in the system, either globally or by specied port. When this feature is
enabled, the system monitors the temperature and signal power levels for the optical transceivers in the specied 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 AdministrationGuide.

DANGER
The procedures in this manual are for qualied service personnel.
Managing temperature settings
The device contains temperature sensors that the software reads based on a congurable 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 congurable up to 100°C.
•The shutdown level is the temperature at which the device reboots. It is set by the device and is not congurable. 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 shuts down in ve minutes. The system restarts ve minutes after the device reaches the
temperature shutdown level.
Temperature threshold levels
The switch fans have two speeds, low and high. The fan speed settings are set by the device, and are not congurable.
During system bootup, the fans run at high speed. If the switch does not detect any fans, the switch shuts down.
After bootup, the fans operate at low speed when the temperature of the switch is below the high limit temperature that is specied in the
following table. If the switch reaches the high limit temperature, the fans operate at high speed until the switch reaches the low limit
temperature specied in the table, at which time the fans decrease to low speed.
If the switch reaches or exceeds the critical (shutdown) temperature for two minutes, the switch shuts down.
NOTE
In addition to the overall temperature of the module, the ICX 7250-24P and ICX 7250-48P modules monitor the temperature
of the Power Over Ethernet (PoE) power supply unit (PSU). When the low limit and high limit temperatures are reached, the PoE
PSU fans change speed using the same algorithm as the module fans. There is no change to the Critical (shutdown)
temperature value for these modules.

Fan detection and error checking policies
During system startup and operation, the Brocade ICX 7250, checks the fan status and automatically performs corrective actions and
generates syslog messages if a problem is detected (refer to the following table).
If the Brocade ICX 7250 determines that there is a problem with the fans, it performs the following actions and generates the following
syslog messages, as shown in the following table.
NOTE
To determine the fan direction (either front to back, or back to front), enter the show chassis command.
TABLE 14 Brocade ICX 7250 fan error detection and resolution
Issue detectedAttempted resolution
During system bootup, no fan is detectedThe system immediately shuts down.
During system bootup, fewer fans than required for
normal operation are detected
System boots up normally, but all fans fail during
system operation
After system bootup, fewer fans than required for
normal operation are detected
After system bootup, two of the power supply fans
are detected as operating in opposite directions
After system bootup, two of the module fans are
detected as operating in opposite directions
After system bootup, the power supply and module
fans are detected as operating in opposite directions
During normal system operation, one of the module
fans reports that it is operating in the incorrect
direction
During normal system operation, the system detects
that a power supply or module fan has been
replaced, and the new fan is operating in the
incorrect direction
System detects that the critical (shutdown)
temperature has been exceeded
The system boots up normally and follows the fan speed and shutdown policy as described in
Temperature threshold levels on page 99. A syslog message is generated that describes the
issue.
The system immediately shuts down. A syslog message describing the issue is generated prior
to shutdown.

The system generates a syslog message when the issue is detected, and every 30 seconds
after detection. If the critical (shutdown) temperature is exceeded for two minutes, the system
shuts down.
Shutdown reset time and syslog message
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!!!
