stacking feature is available.

Installation and safety considerations

You can install the Brocade ICX 7750 in the following ways:

• As a standalone unit on a flat surface.

• In an EIA cabinet using a fixed-rail rack mount kit. The optional 4-post universal rack mount kit

can be order from your switch retailer to support up to a 30" deep rack. The 4-post rack mount
kit includes mid-mount and rear-mount brackets.

• In a 2-post Telco rack using a flush-mount rack kit. The 2-post rack mount ears are included

with the switch and support various mounting positions (refer to

Electrical considerations

To install and operate the switch successfully, ensure compliance with the following requirements:

Figure 10).

• The primary outlet is correctly wired, protected by a circuit breaker, and grounded in

accordance with local electrical codes.

• The supply circuit, line fusing, and wire size are adequate, as specified by the electrical rating

on the switch nameplate.

• The power supply standards are met.

Environmental considerations

For successful installation and operation of the switch, ensure that the following environmental
requirements are met:

• Because the Brocade ICX 7750 can be ordered with fans that move air either front to back or

back to front, be sure to orient your switch with the airflow pattern of any other devices in the
rack. All equipment in the rack should force air in the same direction to avoid intake of exhaust
air.

• Some combinations of intake and exhaust airflows may not be compatible with your

environment. Consult your fan and power supply module FRU kit to determine the correct
configuration.

• The ambient air temperature does not exceed 50°C (122°F) while the Brocade ICX 7750-26Q

or Brocade ICX 7750-48F switch is operating, or 40°C (104°F) while the Brocade ICX
7750-48C switch is operating.

Location considerations

Before installing the device, plan its location and orientation relative to other devices and
equipment. Devices can be mounted in a standard 19-inch equipment rack or on a flat surface.

53-1003084-01

Installation and safety considerations

CAUTION

The site should meet the following requirements:

• Maintain the operating environment as specified in “Environmental considerations” on

page 10.

• The ICX 7750 should be installed with its top/bottom covers parallel to the floor. The ICX 7750

should not be installed upside down.

• Allow a minimum of 3 in. of space between the front and the back of the device and walls or

other obstructions for proper airflow.

• Allow at least 3 in. of space at the front and back of the device for the twisted-pair, fiber-optic,

and power cabling.

• Allow access for installing, cabling, and maintaining the devices.

• Allow the status LEDs to be clearly visible.

• Allow for twisted-pair cables to be routed away from power lines, fluorescent lighting fixtures,

and other sources of electrical interference, such as radios and transmitters.

• Allow for the unit to be connected to a separate grounded power outlet that provides 100 to

240 VAC, 50 to 60 Hz, is within 2 m (6.6 ft) of each device, and is powered from an
independent circuit breaker. As with any equipment, a filter or surge suppressor is
recommended.

2

Cabinet considerations

For successful installation and operation of the switch in a cabinet, ensure the following cabinet
requirements are met:

• The cabinet must be a standard EIA cabinet.

• The equipment in the cabinet is grounded through a reliable branch circuit connection and

maintains ground at all times. Do not rely on a secondary connection to a branch circuit, such
as a power strip.

• Airflow and temperature requirements are met on an ongoing basis, particularly if the switch is

installed in a closed or multicabinet assembly.

• The additional weight of the switch does not exceed the cabinet’s weight limits or unbalance

the cabinet in any way.

• The cabinet is secured to ensure stability in case of unexpected movement, such as an

earthquake.

Recommendations for cable management

Cables can be organized and managed in a variety of ways; for example, use cable channels on the
sides of the cabinet or patch panels to reduce the potential for tangling the cables. The following
list provides some recommendations for cable management:

Before plugging a cable to any port, be sure to discharge any static charge stored on the cable by
touching the electrical contacts to ground surface.

Brocade ICX 7750 Hardware Installation Guide 11
53-1003084-01

Installation tasks

ATTENTION

2

You should not use tie wraps with fiber-optic cables because they are easily overtightened and can
damage the optical fibers. Velcro-like wraps are recommended.

• Plan for the rack space required for cable management before installing the switch.

• Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and

replace the switch, allows for inadvertent movement of the rack, and helps prevent the cables
from being bent to less than the minimum bend radius.

• For easier maintenance, label the cables and record the devices to which they are connected.

• Keep LEDs visible by routing port cables and other cables away from the LEDs.

Attaching a PC or terminal

To assign an IP address, you must have access to the command-line interface (CLI). The CLI is a
text-based interface that can be accessed through a direct serial connection to the device and
through Telnet connections. The CLI is described in detail in the FastIron Ethernet Switch
Administration Guide.

2

Access the CLI by connecting to the console port. After you assign an IP address, you can access
the system through Telnet, or Brocade Network Advisor.

Use the following steps to attach a management station to the console port:

1. Connect a PC or terminal to the console management port on the front of the Brocade ICX
7750 using the mini-USB serial console port cable (Part number 50-1000122-01).

For port pinout information for the mini-USB serial console port, refer to“Pinouts and signaling”
on page 51“.

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.

Connecting to the management port

The Gigabit Ethernet management port (RJ-45) on the Brocade ICX 7750 rear panel provides an
out-of-band network connection to the device. After you assign an IP address, you can access the
Brocade ICX 7750 from anywhere in the attached network using Telnet, a web browser, or other
network management tools, such as Brocade Network Advisor. To prevent unauthorized access,
Brocade recommends that the management port only be connected to a secure private network.

To manage the Brocade ICX 7750 through its management port, connect the port to the
management Ethernet network using Category 5 or better cable.

Management of the Brocade ICX 7750 is described in detail in the FastIron Ethernet Switch
Administration Guide.

Installing an SFP+ transceiver

To monitor the transceivers, the show media command output shows the transceiver information
for all interfaces on the switch. Brocade provides support for third-party transceivers, but may
require a Brocade transceiver be used for troubleshooting.

Support will not be provided if there is an issue with a third-party transceiver.

Complete the following steps to install an SFP+ transceiver.

1. Remove any protector plugs from the transceivers and the ports.

2. Making sure that the bail (wire handle) is in the unlocked position, place the SFP+ transceiver
in the correctly oriented position on the port, as shown in

3. Slide the SFP+ transceiver into the port until you feel it click into place; then close the bail.

Figure 18.

Each SFP+ transceiver has a 10-pad gold-plated edge connector on the bottom. The correct position
to insert an SFP+ transceiver in the upper row of ports is with the gold-plated edge down. The correct
position to insert an SFP+ transceiver in the lower row of ports is with the gold-plated edge up.

LED activity interpretation

System activity and status can be determined through the activity of the LEDs on the switch.

There are three possible LED states: off (no light), a steady light, and a flashing light. Flashing lights
may be slow, fast, or flickering. The LED colors are either green or amber.

3

Sometimes, the LEDs flash either of the colors during boot, POST, or other diagnostic tests. This is
normal; it does not indicate a problem unless the LEDs do not indicate a healthy state after all boot
processes and diagnostic tests are complete.

Brocade ICX 7750 front panel LEDs

The Brocade ICX 7750-26Q has the following LEDs on the front panel:

• Two power supply unit (PSU) bicolor status LEDs (green and amber) labeled PSU1 and PSU2.

Diagnostic tests and monitoring

Brocade FastIron software includes diagnostic tests to help you troubleshoot the hardware. System
diagnostic software is designed to fulfill the purpose of offline diagnostics. In offline diagnostics,
you must turn the diagnostic flags on or off to execute diagnostic tests during the next bootup.

The CLI commands for system diagnostic tests are dm diag and dm alt-diag. These diagnostic tests
verify all available hardware components including:

• I2C devices

• EEPROMS

• CPU packet

• Test MAC alignment

• Line rate

During system diagnostic testing, the system is completely under the control of the diagnostic
software. All hardware components are verified, and results are displayed on the console. In cases
where a failure is detected, results and corrective actions will be displayed. After the system
diagnostic testing is complete, the system exits from the diagnostic mode and reloads the system
for normal operation.

Hardware maintenance schedule

Brocade ICX 7750 switch hardware components require minimal maintenance. Brocade
recommends cleaning the fiber-optic connectors on a fiber-optic port and the connected fiber cable
each time you disconnect the cable.

Replacing a copper or fiber-optic module

You can remove an SFP, SFP+, or QSFP+ transceiver from a slot and replace it with a new one while
the Brocade ICX 7750 is powered on and running.

This section provides information about the following tasks:

• Removing a copper or fiber-optic module

• Cleaning the fiber-optic connectors

• Cabling a fiber-optic module

Removing a copper or fiber-optic module

You can remove an SFP, SFP+, or QSFP+ transceiver from a slot while the Brocade ICX 7750 is
powered on and running.

While removing a copper or fiber-optic module, be sure to wear an ESD wrist strap that is
connected to ground.

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 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.

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.

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

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

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.

Cabling a fiber-optic module

Use 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.

2. Before cabling a fiber-optic transceiver, Brocade strongly recommends cleaning the cable
connectors and the port connectors. For more information, refer to

connectors” on page 37.

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

4. Observe the link and active LEDs to determine if the network connections are functioning
properly.

“Cleaning the fiber-optic

FRU removal and replacement procedures

CAUTION

Cleaning the fiber-optic connectors

To avoid problems with the connection between the fiber-optic transceiver (SFP, SFP+, or QSFP+)
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, SFP+, or QSFP+ connector, make sure to keep the protective covering in
place.

FRU removal and replacement procedures

The field-replaceable units (FRUs) in the Brocade ICX 7750 can be removed and replaced by using
a #1 Phillips screwdriver. The switches can continue operating during the FRU replacement if the
conditions specified in these procedures are followed. This covers both the power supply unit (PSU)
FRUs and fan FRUs.

4

This document describes how to change FRUs for units with either an air intake or air exhaust.
You must replace a failed FRU with a FRU of the same type. This applies to both power supplies
and fans. A new FRU must have the same part number (P/N) as the FRU being replaced. The
manufacturing P/N is located on the top of the FRU.

If a mismatched power source or fan assembly is installed by mistake, a warning is sent to the
console. The warning messages will be similar to the following:

• For a fan mismatch: [WARNING, Brocade ICX 7750, MISMATCH in Fan Air Flow direction.

Replace FRU with fan air flows in the same direction.

• For a power supply: [WARNING, Brocade ICX 7750, MISMATCH in PSU Air Flow direction.

Replace PSU with air flows in the same direction

You can use external labels as a guide. The power supplies and fan assemblies are labeled with an
airflow symbol on the faceplate to indicate whether the assembly takes in or exhausts air. The
symbol also appears on the top of the FRU. All FRUs in a chassis must have the same label affixed
so that airflow direction is consistent.

FIGURE 23 Examples of airflow symbols

Figure 23 illustrates examples of the airflow labels.

The green E symbol indicates an exhaust FRU. This unit pulls air in from the front of the switch and
exhausts it out the rear side. This is called front-to-back airflow or forward airflow.

The orange I symbol indicates an intake FRU. This unit pulls air in from the rear side of the switch
and exhausts it out the front side. This is called back-to-front airflow or reverse airflow.

The show chassis command displays a device’s airflow direction: Front-to-Back or Back-to-Front.

Replacing a power supply unit

Remove the power cord from a power supply before you install it in or remove it from the device.
Otherwise, the power supply or the device could be damaged as a result. (The device can be
running while a power supply is being installed or removed, but the power supply itself should not
be connected to a power source.)

For the Brocade ICX 7750 devices, be sure that the airflow direction of the power supply unit
matches that of the installed fan tray. The power supplies and fan trays are clearly labeled with
either a green arrow with an “E”, or an orange arrow with an “I.”

Maintain all power supply and fan assemblies in operational condition to provide redundancy.

Because the cooling system relies on pressurized air, do not leave any of the power supply and
fan assembly slots empty longer than two minutes while the switch is operating. If a power supply
or fan assembly fails, leave it in the switch until it can be replaced.

Disassembling any part of the power supply and fan assembly voids the warranty and regulatory
certifications. There are no user-serviceable parts inside the power supply and fan assembly.

Tab le 16 on page 32 describes the Brocade ICX 7750 power supply status LED colors, behaviors,

and actions required, if any.

Determining the need to replace a power supply

Use one of the following methods to determine the status of the power supplies:

38 Brocade ICX 7750 Hardware Installation Guide

Replacing a power supply unit

CAUTION

• Check the PSU1/PSU2 LEDs on the switch front panel (refer to “LED patterns” on page 29) or

power supply status LED (refer to Table 16 on page 32).

• Enter the show chassis command at the prompt to display power supply status.

Time and items required

Replacing a power supply in the Brocade ICX 7750 should take less than two minutes to complete.

You need the following items to replace a power supply in a Brocade ICX 7750:

• A new power supply (must have the same part number and the same airflow label as the power

supply being replaced).

• A #1 Phillips screwdriver.

Replacing a power supply

Complete the following steps to replace a power supply in a Brocade ICX 7750.

1. To leave the Brocade ICX 7750 in service while replacing a power supply, verify that the other
power supply (the one not being replaced) has been powered on for at least four seconds and
has a steady green status LED.

Replacing fan trays

For the Brocade ICX 7750 devices, be sure that the airflow direction of the fan tray matches
thatof the installed power supply unit. The power supplies and fan trays are clearly labeled with
either a green arrow with an “E”, or an orange arrow with an “I.”

The Brocade ICX 7750 includes four redundant, hot-swappable fan units. However, it can run on
one power supply and three fans. In that case, the empty power supply and fan slot must be
covered using the filler panels.

Tab le 16 on page 32). If the LED is not steady green, ensure that the

“LED patterns” on page 29).

Maintain all power supply and fan assemblies in operational condition to provide redundancy.

Because the cooling system relies on pressurized air, do not leave any of the power supply and
fan assembly slots empty longer than two minutes while the switch is operating. If a power supply
or fan assembly fails, leave it in the switch until it can be replaced.

Disassembling any part of the power supply and fan assembly voids the warranty and regulatory
certifications. There are no user-serviceable parts inside the power supply and fan assembly.

CAUTION All devices with DC power supplies (Brocade ICX 7750 ) are intended for installation in

restricted access areas only. A restricted access area is where access can be gained only
by service personnel through the use of a special tool, lock and key, or other means of
security, and is controlled by the authority responsible for the location.

VORSICHT Alle Geräte mit Gleichstromeingangsschaltung (Brocade ICX 7750 ) sind nur zur

Installation in Sperrbereichen bestimmt. Ein Sperrbereich ist ein Ort, zu dem nur
Wartungspersonal mit einem Spezialwerkzeug, Schloss und Schlüssel oder einer
anderen Schutzvorrichtung Zugang hat. Er unterliegt außerdem der Kontrolle durch die
für den Standort verantwortliche Stelle.

MISE EN GARDE Tous les équipements dotés d'un bloc d'alimentation en courant continu (Brocade ICX

7750 ) sont conçus pour l'installation dans des zones à accès réglementé uniquement.
Une zone à accès réglementé est un local qui n'est accessible que par le personnel
d'entretien à l'aide d'un outil, verrou ou clé conçus à cet effet, ou de tout autre accessoire
de sécurité, et qui est contrôlé par l'autorité responsable de ce local.

PRECAUCIÓN Todos aquellos dispositivos con fuentes de alimentación de CC (Brocade ICX 7750 )

están diseñados para su instalación en zonas de acceso restringido solamente. Una zona
de acceso restringido es un lugar al que sólo puede acceder personal de mantenimiento
haciendo uso de una herramienta especial, una llave y un candado, o algún otro medio

Cautions

CAUTION Do not install the device in an environment where the operating ambient temperature

might exceed 50° C (122° F).

VORSICHT Das Gerät darf nicht in einer Umgebung mit einer Umgebungsbetriebstemperatur von über

50° C (122° F) installiert werden.

MISE EN GARDE N'installez pas le dispositif dans un environnement où la température d'exploitation

ambiante risque de dépasser 50° C (122° F).

PRECAUCIÓN No instale el instrumento en un entorno en el que la temperatura ambiente de operación

pueda exceder los 50° C (122° F).

CAUTION Make sure the airflow around the front, sides, and back of the device is not restricted.

VORSICHT Stellen Sie sicher, dass an der Vorderseite, den Seiten und an der Rückseite der Luftstrom

nicht behindert wird.

MISE EN GARDE Vérifiez que rien ne restreint la circulation d'air devant, derrière et sur les côtés du

dispositif et qu'elle peut se faire librement.

PRECAUCIÓN Asegúrese de que el flujo de aire en las inmediaciones de las partes anterior, laterales y

posterior del instrumento no esté restringido.

CAUTION Use a separate branch circuit for each AC power cord, which provides redundancy in case

one of the circuits fails.

VORSICHT Es empfiehlt sich die Installation eines separaten Stromkreiszweiges für jede

Wechselstrom-Elektroschnur als Redundanz im Fall des Ausfalls eines Stromkreises.

MISE EN GARDE Utilisez un circuit de dérivation différent pour chaque cordon d’alimentation C.A. Ainsi, il y

aura un circuit redondant en cas de panne d’un des circuits.

PRECAUCIÓN Use un circuito derivado separado para cada cordón de alimentación de CA, con lo que se

proporcionará redundancia en caso de que uno de los circuitos falle.

CAUTION Ensure that the device does not overload the power circuits, wiring, and over-current

protection. To determine the possibility of overloading the supply circuits, add the ampere
(amp) ratings of all devices installed on the same circuit as the device. Compare this total
with the rating limit for the circuit. The maximum ampere ratings are usually printed on the
devices near the input power connectors.

VORSICHT Stromkreise, Verdrahtung und Überlastschutz dürfen nicht durch das Gerät überbelastet

werden. Addieren Sie die Nennstromleistung (in Ampere) aller Geräte, die am selben
Stromkreis wie das Gerät installiert sind. Somit können Sie feststellen, ob die Gefahr einer
Überbelastung der Versorgungsstromkreise vorliegt. Vergleichen Sie diese Summe mit der
Nennstromgrenze des Stromkreises. Die Höchstnennströme (in Ampere) stehen
normalerweise auf der Geräterückseite neben den Eingangsstromanschlüssen.

MISE EN GARDE Assurez-vous que le dispositif ne risque pas de surcharger les circuits d'alimentation, le

câblage et la protection de surintensité. Pour déterminer le risque de surcharge des
circuits d'alimentation, additionnez l'intensité nominale (ampères) de tous les dispositifs
installés sur le même circuit que le dispositif en question. Comparez alors ce total avec la
limite de charge du circuit. L'intensité nominale maximum en ampères est généralement
imprimée sur chaque dispositif près des connecteurs d'entrée d'alimentation.

PRECAUCIÓN Verifique que el instrumento no sobrecargue los circuitos de corriente, el cableado y la

protección para sobrecargas. Para determinar la posibilidad de sobrecarga en los circuitos
de suministros, añada las capacidades nominales de corriente (amp) de todos los
instrumentos instalados en el mismo circuito que el instrumento. Compare esta suma con
el límite nominal para el circuito. Las capacidades nominales de corriente máximas están
generalmente impresas en los instrumentos, cerca de los conectores de corriente de
entrada.

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.

VORSICHT Verwenden Sie den Befehl "erase startup-config" (Löschen Startup-Konfig) nur für neue

Systeme. Wenn Sie diesen Befehl in ein bereits konfiguriertes System eingeben, löscht
der Befehl die Konfiguration. Falls Sie aus Versehen die Konfiguration eines bereits
konfigurierten Systems löschen, geben Sie den Befehl "Write Memory" (Speicher
schreiben) ein, um die laufende Konfiguration in der Startup-Konfig-Datei zu speichern.

MISE EN GARDE N'utilisez la commande erase startup-config que pour les nouveaux systèmes. Si vous

entrez cette commande sur un système que vous avez déjà configuré, elle efface la
configuration. Si vous effacez la configuration par accident sur un système configuré,
entrez la commande write memory pour enregistrer la configuration actuelle dans le
fichier startup-config.

PRECAUCIÓN Use el comando erase startup-config (borrar configuración de inicio) para sistemas

nuevos solamente. Si usted introduce este comando en un sistema que ya ha
configurado, el comando borrará la configuración. Si usted borra accidentalmente la
configuración en un sistema ya configurado, introduzca el comando write memory
(escribir memoria) para guardar la configuración en ejecución en el archivo
startup-config.
