Installation and safety considerations

Electrical considerations

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

• 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.

The site should meet the following requirements:

• Maintain the operating environment as specified in “Environmental considerations” on page 12.

• 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.

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.

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.

Power supplies

The Brocade ICX 7750 supports alternating-current (AC) and direct-current (DC) power supplies. The Brocade ICX 7750 is capable of
running on one power supply and three fans. The second power supply and fourth fan provide redundancy.

If the second power supply and fourth fan slots are unused, you must cover them with filler panels.

Brocade recommends that the Brocade ICX 7750-48C operate with two power supplies and four fan trays installed. If a power

supply or fan tray fails, it must be replaced as soon as possible.

AC and DC power supplies cannot be installed and used in the same device. Mismatched power supplies in the same device cause

continual reboot on power up.

Installing and replacing a power supply unit

When installing or replacing a power supply unit, keep in mind the following:

• Power supplies can be swapped in or out while the device is running. The remaining power supply provides enough power for

the device.

• The airflow direction of the power supply must match that of the installed fan trays. All must be either exhaust or intake.

Power supplies are hot-swappable. However, they should be inserted or removed without a power cord being
connected to a power source to avoid damage.

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

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 Brocade FastIron Management Configuration Guide.

Installing an SFP+ or a QSFP+ 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.

Passive SFP+ and QSFP+ removable media devices are not supported. Use of passive devices may lead to unstable networks if

utilized. Brocade-branded removable media devices are recommended for proper operation of the switch.

You can install a new transceiver in a slot while the device is powered on and running.

Before installing or removing a fiber-optic transceiver, have the following items available:

• The protective covering that you removed from the fiber-optic transceiver port when you initially installed the module.

• An ESD wrist strap with a plug for connection to the ESD connector on the router chassis.

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

Laser radiation. Do not view directly with optical instruments. Class 1M laser products.

24 Brocade ICX 7750 Switch Hardware Installation Guide

When 10 GbE fiber-optic ports on the Brocade ICX 7750 are disabled, the laser light remains on even though the port link is down.

Connecting network devices

NOTE

Use the following steps to install a 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. Remove any protector plugs from the transceivers and the ports.

4. Making sure that the bail (wire handle) is in the unlocked position, place the transceiver in the correctly oriented position on the

port, as shown in Figure 19.

5. Slide the transceiver into the port until you feel it click into place; then close the bail. Transceivers are keyed to prevent incorrect

insertion.

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.

Connecting network devices

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

Connectors

For port information, refer to “Data port specifications (Ethernet)” on page 52.

Connecting a network device to a copper port

For copper connections to another Brocade device or any other devices, use straight-through or crossover UTP cabling.

Brocade ICX 7750 Switch Hardware Installation Guide 25
53-1003900-02

Connecting network devices

NOTE

Automatic MDI or MDIX detection

All 10/100/1000 Mbps and 10 Gbps Ethernet copper ports on the devices support automatic Media Dependent Interface (MDI) and
Media Dependent Interface Crossover (MDIX) detection. Automatic MDI or MDIX detection is enabled on all copper ports by default. For
each port, you can disable automatic MDI or MDIX detection, designate the port as an MDI port, or designate the port as an MDIX port.

For more information about automatic MDI or MDIX detection and configuration details, refer to the Brocade FastIron Management
Configuration Guide.

Connecting a network device to a fiber port

For direct attachment from the device to a 1 GbE network interface card, switch, or router using a fiber-optic transceiver, you will need fiber
cabling with an LC connector.

For information about transceivers supported on Brocade ICX 7750 devices, refer to the Brocade Optics Family Data Sheet:

To connect the device to another network device using a fiber port, you must complete the following tasks:

• Install a fiber-optic transceiver (SFP+ or QSFP+). Refer to “Installing an SFP+ or a QSFP+ transceiver” on page 24.

• Cable the fiber-optic transceiver

Cabling a fiber-optic transceiver

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 “Cleaning the fiber-optic connectors” on page 26.

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 activity LEDs to determine if the network connections are functioning properly. For more information about

the LED indicators, refer to “LED activity interpretation” on page 33.

To verify that a Brocade ICX 7750 can reach another device through the network, use the ping command at any level of the CLI.

For more information, refer to the Brocade FastIron Management Configuration Guide.

Cleaning the fiber-optic connectors

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

Connecting breakout cables to 40 GbE ports

A 40 GbE breakout cable can only be used on standalone Brocade ICX 7750 devices to break out certain 40 GbE QSFP+ ports into four
10 GbE sub-ports. (Refer to “Breakout cables” on page 9.)

Stacking Brocade ICX 7750 switches

NOTE

NOTE

Any previous configuration must be removed from a 40 GbE port before it can be broken out into sub-ports. Refer to the Brocade

FastIron Management Configuration Guide for more information.

Stacking cannot be enabled on Brocade ICX 7750 devices that have a breakout configuration on any 40 GbE ports, and vice

versa.

Stacking Brocade ICX 7750 switches

Brocade ICX 7750 devices support chassis-class high availability stacking with hitless failover on six full-duplex 40 Gbps stacking ports.

Brocade ICX 7750 Switches can be stacked using standard full-40 Gbps QSFP+ ports per switch, providing a maximum stacking
bandwidth of 480 Gbps.

Stacking ports

There are six QSFP+ ports on the front panel (slot 2) and six QSFP+ ports on the rear panel (slot 3) that can be used as stacking ports.
Use either the front panel stacking ports or the rear panel stacking ports. No mixed combination of front and rear ports is allowed.

Figure 20 shows the Brocade ICX 7750 stacking ports.

FIGURE 20 Front panel stacking ports

The available front panel stacking ports are 1/2/1 through 1/2/6.

Ports 1/2/1 and 1/2/4 are default stacking ports on the front panel. Default stacking ports have the capability to accept special stacking
packets during a CLI-initiated command sequence of the Secure Setup utility. The default ports can be changed to ports 1/3/1 and 1/3/4
on the rear panel. No other default ports are allowed.

Brocade ICX 7750 Switch Hardware Installation Guide 27
53-1003900-02

Stacking Brocade ICX 7750 switches

NOTE

FIGURE 21 Rear panel stacking ports

The available rear panel stacking ports are ports 1/3/1 through 1/3/6.

Unused stacking ports can be used as data ports. For example, you can elect to use only one default port as a stacking port and

use the other default port as a data port. Furthermore, when a Brocade ICX 7750-6Q stacking module is not configured for

stacking, its ports can be used as data ports.

A stack connection can also be a trunked link consisting of multiple ports, which increases stacking bandwidth and provides resiliency. Up
to two stack trunks are supported, and each trunk can include up to three ports.

Only ports that are in sequential order can be configured as a stacking trunk. A default port; that is, either port 1/2/1 or 1/2/4 in slot 2 or port
1/3/1 or 1/3/4 in slot 3, is always the first sequential port in a trunk.

Possible 3-port trunks:

• 1/2/1 to 1/2/3

• 1/2/4 to 1/2/6

• 1/3/1 to 1/3/3

• 1/3/4 to 1/3/6

Possible 2-port trunks:

• 1/2/1 to 1/2/2

• 1/2/4 to 1/2/5

• 1/3/1 to 1/3/2

• 1/3/4 to 1/3/5

Stacking configuration requirements

Before configuring the 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.

28 Brocade ICX 7750 Switch Hardware Installation Guide

53-1003900-02

Stacking Brocade ICX 7750 switches

NOTE

Stacking cables

Use QSFP+ direct attached active copper stacking cables or QSFP+ fiber optic cables to connect Brocade ICX 7750 devices in a stack.
The copper cable lengths for 40 GbE ports are 1 meter, 3 meters, and 5 meters.

Extended distance stacking

Because Brocade ICX 7750 devices use Ethernet for the inter-switch stack connections, the deployment options are greatly increased. If
standard copper stacking cables are used, the inter-switch connections can be up to 5 meters, which is usually sufficient for locally
distributed stacks such as in top-of-rack (ToR) applications. For broader distribution, fiber-optic cables should be used, allowing a stack to
be deployed across multiple physical locations such as the wiring closets of an office building.

The use of 40GBASE-LR4 optics for extended distance stacking is supported only in the default stacking ports (1/2/1, 1/2/4, 1/3/1,

or 1/3/4). Due to the limitation on the Brocade ICX7750-48C and the ICX7750-48F, where 40GBASE-LR4 optics are supported

only in ports 1/2/5, 1/2/6, 1/3/5, or 1/3/6, extended distance stacking is not supported for 40GBASE-LR4 optics.

Table 7 shows the approved optics and stacking distance combinations.

TABLE 7 Fiber-optic options and stacking distances

Stacking cable option Description Maximum stacking distance

40GBase-SR4 fiber-optic cable 40G QSFP-QSFP 100 meter

400 meter (OM4 multimode fiber)

40GBase-LR4 fiber-optic cable 40G QSFP-QSFP 10 kilometers for ICX 7750-26Q device only

Stack size

The Brocade ICX 7750 supports up to 12 units in a stack. You can mix any number of Brocade ICX 7750-26Q, Brocade ICX 7750-48F,
or Brocade ICX 7750-48C devices together in a stack.

Stacking topologies

Both linear and ring topologies are supported in a stack. In a linear stack topology, there is a connection between each switch that carries
two-way communications across the stack.

For example, in a three-unit stack using a linear topology, unit 1 connects to unit 2, and unit 2 connects to unit 3.

Figure 22 shows a supported rear panel linear stacking topology.

Brocade ICX 7750 Switch Hardware Installation Guide 29
53-1003900-02

Stacking Brocade ICX 7750 switches

FIGURE 22 Rear panel linear stacking topology

In a 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.

For example, in a three-unit stack using a ring topology, unit 1 connects to unit 2, unit 2 connects to unit 3, and unit 3 connects to unit 1.

Figure 23 shows a supported rear panel ring stacking topology.

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.

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

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.

System diagnostic testing runs at link speeds 10 Gbps and 40 Gbps (QSFP+ ports) depending on the speed of the link being tested and
the type of port.

Temperature threshold levels

The fan speed settings are set by the Brocade ICX 7750, and are not configurable.

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+, 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

• Cabling a fiber-optic module

• Cleaning the fiber-optic connectors

Removing a copper or fiber-optic module

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

Before removing a fiber-optic transceiver, have the following items available:

• The protective covering that you removed from the fiber-optic transceiver port when you initially installed the module.

• An ESD wrist strap with a plug for connection to the ESD connector on the router chassis.

DANGER

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

Laser radiation. Do not view directly with optical instruments. Class 1M laser products.

When 10 GbE fiber-optic ports on the Brocade ICX 7750 are disabled, the laser light remains on even though the port link is down.

To remove a copper or fiber-optic module from a transceiver 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+, 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.

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

For more information, refer to “Cleaning the fiber-optic connectors” on page 42.

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.

Cleaning the fiber-optic connectors

To avoid problems with the connection between the fiber-optic transceiver (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.

FRU removal and replacement procedures

NOTE

To clean the fiber cable connectors, Brocade recommends using a fiber-optic reel-type cleaner. When not using an 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.

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 tray 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 trays 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 30 illustrates examples of the airflow labels.

FIGURE 30 Examples of airflow symbols

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.

CAUTION

CAUTION

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 trays in operational condition to provide redundancy.

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

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

Table 19 on page 39 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:

• Check the PSU1 and PSU2 LEDs on the switch front panel or power supply status LED (refer to “LED patterns” on page 37).

• 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)

10. Plug the power cord into the power supply to power on the unit.

The power supply will immediately attempt to power up.

11. Verify that the LED on the new power supply displays steady green while the Brocade ICX 7750 is operating. If the LED is not

steady green, ensure that the power supply is securely installed and seated properly. Alternatively, check the PSU1 and PSU2

LEDs on the switch front panel (refer to “LED patterns” on page 37).

You can enter the show chassis command at the command line prompt to display power supply status.

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.

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

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