For the Brocade VDX 6740T and Brocade VDX 6740T-1G, be sure to keep the vents on the sides near
the front of the switch are unobstructed.
The procedures in this manual are for qualified service personnel.
Electrical considerations
To install and operate the switch successfully, ensure compliance with the following requirements:
• The primary outlets are 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. Refer to Table 12 for more information.
Environmental considerations
For successful installation and operation of the switch, ensure that the following environmental
requirements are met:
• Because the Brocade VDX 6740 switches can be ordered with fans that move air either front to
back (exhaust) or back to front (intake), 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.
• For the Brocade VDX 6740 - A maximum flow of 43.7 cubic meters/hour (25.7 cubic
feet/minute) at the intake vents.
• For the Brocade VDX 6740T and Brocade VDX 6740T-1G - A maximum flow of 83.8 cubic
meters/hour (49.3 cubic feet/minute) at the intake vents.
• The ambient air temperature does not exceed 40C (104F) while the switch is operating.
Rack considerations
For successful installation and operation of the switch in a rack, ensure the following rack
requirements are met:
• The rack must be a standard EIA rack.
• The rack space required is one rack unit (1U) 44.45 mm (1.75 in.) high and 482.60 mm (19
in.) wide.
8Brocade VDX 6740 Hardware Reference Manual
53_1002829_02
Installation and safety considerations
NOTE
2
• The equipment in the rack 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.
• Ensure that the rack mounting does not impede airflow or negatively affect temperature
requirements, particularly if the switch is installed in a closed or multirack assembly. The
Brocade VDX 6740T and Brocade VDX 6740T-1G have airflow openings on either side of the
switch toward the front. Ensure that these openings are not obstructed.
• The additional weight of the switch does not exceed the rack’s weight limits or unbalance the
rack in any way.
• The rack is secured to ensure stability in case of unexpected movement, such as an
earthquake.
Recommendations for cable management
The minimum radius to which a 50-micron cable can be bent under full tensile load is 5.1 cm (2
in.). For a cable under no tensile load, that minimum is 3.0 cm (1.2 in.).
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:
You should not use tie wraps with optical cables because they are easily overtightened and can
damage the optic 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.
Items required for installation
The following items are required for installing, configuring, and connecting the Brocade VDX 6740
switches for use in a network and fabric:
• A workstation with an installed terminal emulator, such as HyperTerminal.
• An unused IP address and corresponding subnet mask and gateway address.
• A serial cable (provided).
• An Ethernet cable.
• (Optional) Access to an FTP server or Brocade-branded USB device for backing up the switch
configuration.
• If mounting in the iDataplex IBM 15.5-inch depth rack, the Brocade iDataplex rack mount kit.
Standalone installation for the Brocade VDX 6740 switches
NOTE
2
Standalone installation for the Brocade VDX 6740 switches
Complete the following steps to install the Brocade VDX 6740 as a standalone unit.
1. Unpack the Brocade VDX 6740 switch and verify the items listed in “Items included with the
Brocade VDX 6740 switches” on page 7 are present and undamaged.
2. Apply the adhesive rubber feet. Applying the rubber feet to the switch helps prevent the switch
from sliding off the supporting surface.
a. Clean the indentations at each corner of the bottom of the switch to ensure that they are
free of dust or other debris that might lessen the adhesion of the feet.
b. With the adhesive side against the chassis, place one rubber foot in each indentation and
press into place.
3. Place the switch on a flat, sturdy surface.
4. Provide power to the switch as described in “Providing power to the switch” on page 10.
Do not connect the switch to the network until the IP address is correctly set. For instructions on how
to set the IP address, refer to “Setting the switch IP address” on page 15.
Rack installation options for the Brocade VDX 6740 switches
Follow the installation instructions shipped with the appropriate rack mount kit:
• 1U-2U Universal 4-Post Rail Mount Kit (Brocade VDX 6740T and Brocade VDX 6740T-1G only)
• 1U-2U Universal 2-Post Rail Mount Kit (Brocade VDX 6740T and Brocade VDX 6740T-1G only)
Providing power to the switch
Perform the following steps to provide power to the Brocade VDX 6740 switches.
1. Connect the power cords to both power supplies, and then to power sources on separate
circuits to protect against failure. Ensure that the power cords have a minimum service loop of
15.2 cm (6 in.) available and are routed to avoid stress.
2. For the Brocade VDX 6740, flip the switch on each power supply to I.
For the Brocade VDX 6740T and Brocade VDX 6740T-1G, the power supplies power up as soon
as they are plugged in.
The power supply LEDs display green. The power LED on the front of the switch turns green as
well. The system status LED on the front panel will be amber until POST completes and then it
will turn green.

Configuration for the Brocade VDX 6740 switches
The Brocade VDX 6740 switches can be configured in VCS™ mode, which is enabled by default.
In VCS mode, the switch is part of an Ethernet fabric involving two or more VCS-enabled switches.
VCS technology embodies the concepts of distributed intelligence and logical chassis. Distributed
intelligence means that all configuration and destination information is automatically distributed to
each member switch in the fabric. Distributed intelligence has three major characteristics:
• The fabric is self-forming. When two VCS-enabled switches are connected, the fabric is
automatically created and the switches discover the common fabric configuration.
• The fabric is masterless. No single switch stores configuration information or controls fabric
operations. Any switch can fail or be removed without causing disruptive fabric downtime or
delayed traffic.
• The fabric is aware of all members, devices, and Virtual Machines (VMs). Automatic Migration
of Port Profiles (AMPP) supports VM migration to another physical server. If the VM moves, it is
automatically reconnected to all of its original resources.
Logical chassis means that the entire VCS fabric appears and can be managed as a single Layer 2
switch. There are three major characteristics to logical chassis:
• Each physical switch in the fabric can be managed as if it were a blade in a chassis. When a
VCS-enabled switch is connected to the fabric, it inherits the configuration of the fabric and the
new ports become available immediately.
• You can manage the entire fabric from any switch.
• You can manage the edge switches in the fabric as if they were a single switch.
You perform all configuration tasks in this guide using a serial connection from a workstation or
terminal to the switch.
Complete the following steps to create a serial connection to the switch.
1. Connect the serial cable to the serial port on the switch and to an RS-232 serial port on
the workstation or terminal device.
If the serial port on the workstation or terminal device is RJ45 instead of RS-232, remove the
adapter on the end of the serial cable and insert the exposed RJ45 connector into the RJ45
serial port on the workstation.
2. Open a terminal emulator application (such as HyperTerminal on a PC, or TERM, TIP, or Kermit
in a UNIX environment), and configure the application as follows:
• In a Windows environment, enter the following values: 9600 bits per second, 8 databits,
no parity, 1 stop bit, and no flow control.
• In a UNIX environment using TIP, enter the following string at the prompt:
tip /dev/ttyb -9600
If ttyb is already in use, use ttya instead.
The serial port is located on the port side of the Brocade VDX 6740 switches. The Brocade VDX
6740 uses an RJ-45 connector for the serial port. The Brocade VDX 6740T and Brocade VDX
6740T-1G use a mini-USB connector for the serial port. An RJ-45 to DB9 adapter is also provided
with the switch. The cable supplied is a rollover cable.
To protect the serial port from damage, keep the cover on the port when not in use.
The serial port can be used to connect to a workstation to configure the IP address for the Brocade
VDX 6740 before connecting the switch to a fabric or IP network. The serial port’s parameters are
fixed at 9600 baud, 8 data bits, and no parity, with flow control set to None.

The factory-configured default accounts on the switch are admin, user, and root. Use the default
administrative account as shown in Table 2 to log in to the switch for the first time and to perform
the basic configuration tasks.
The root account is reserved for development and manufacturing. The user account is read-only
and used primarily for system monitoring.
TABLE 2Default administrative account names and passwords

Changing the default account passwords
When you change the default account password after you log in for the first time, only the default
password rule is in effect. The rule specifies a minimum password length of eight characters. For
advanced user and role management, including setting password rules, refer to the Security
chapter of the Brocade Network OS Administrator’s Guide.

2. Enter the username command followed by the account name and the password parameter.
3. When prompted, enter the new password. and press Enter.
You can configure the Brocade VDX 6740 switches with a static IP address, or you can use a
Dynamic Host Configuration Protocol (DHCP) server to set the IP address of the switch. DHCP is
enabled by default. The Brocade VDX 6740 switches support both IPv4 and IPv6 format addresses.
Using DHCP to set the IP address
When using DHCP, the Brocade VDX 6740 switches obtain the IP address, subnet mask, and
default gateway address from the DHCP server. The DHCP client can only connect to a DHCP server
that is on the same subnet as the switch. If your DHCP server is not on the same subnet as the
Brocade VDX 6740, use a static IP address.
To set an IPv4 IP address using DHCP, complete the following steps.
1. Log in to the switch using the admin account.
2. Configure the management interface with the following command:
3. Configure the IP address using the following command:
Setting a static IP address
Complete the following steps to set a static IP address.
1. Log in to the switch using the default password (the default password is password).
2. Use the ip address command to set the Ethernet IP address.
switch(config)# interface Management 1/0
switch(config-Management-1/0)# ip address dhcp
If you are going to use an IPv4 IP address, enter the IP address in dotted decimal notation. You
should also disable DHCP and enter a gateway address as well.
switch(config)# interface Management 1/0
switch(config-Management-1/0)# no ip address dhcp
switch(config-Management-1/0)# ip address 10.24.85.81/20
To set up a default gateway, add an ip route in rbridge mode.
switch(config-rbridge-id-10)# ip route 0.0.0.0/0 10.24.80.1
switch# copy running-config startup-config
If you are going to use an IPv6 address, enter the network information in semicolon-separated
notation as prompted after the ipv6 address operand.
switch(config)# interface Management 1/0
switch(config-Management-1/0)# no ip address dhcp

Stateless IPv6 autoconfiguration
IPv6 allows assignment of multiple IP addresses to each network interface. Each interface is
configured with a link local address in almost all cases, but this address is only accessible from
other hosts on the same network. To provide for wider accessibility, interfaces are typically
configured with at least one additional global scope IPv6 address. IPv6 autoconfiguration allows
more IPv6 addresses, the number of which is dependent on the number of routers serving the local
network and the number of prefixes they advertise.
When IPv6 autoconfiguration is enabled, the platform will engage in stateless IPv6
autoconfiguration. When IPv6 autoconfiguration is disabled, the platform will relinquish usage of
any autoconfigured IPv6 addresses that it may have acquired while IPv6 autoconfiguration was
enabled. This same enabled or disabled state also enables or disables the usage of a link local
address for each managed entity (though a link local address will continue to be generated for
each switch) because those link local addresses are required for router discovery.
16Brocade VDX 6740 Hardware Reference Manual
53_1002829_02
The enabled or disabled state of autoconfiguration does not affect any static IPv6 addresses that
may have been configured. Stateless IPv6 autoconfiguration and static IPv6 addresses can coexist.
Setting stateless IPv6 autoconfiguration
To configure stateless IPv6 autoconfiguration, complete the following steps.
1. Issue the configure terminal command to enter global configuration mode.
2. Take the appropriate action based on whether you want to enable or disable IPv6
autoconfiguration:
• Enter the ipv6 address autoconfig command to enable IPv6 autoconfiguration for all
managed entities on the target platform.
• Enter the no ipv6 address autoconfig command to disable IPv6 autoconfiguration for all
managed entities on the target platform.
Changing the RBridge ID
If you are going to have more than one switch in a fabric, each switch must have a unique RBridge
ID. The default RBridge ID for any Brocade VDX 6740 is 1. Use the vcs rbridge-id [rbridge-id]
command to change the default RBridge ID. You should be in privileged EXEC mode to run the
command. If you have made any other configuration changes you want to persist, be sure to save
your running configuration to the startup configuration before running the vcs rbridge-id command
as this command reboots the switch.
Changing the RBridge ID
3
Enter the vcs rbridge-id [rbridge-id] command.
switch# vcs rbridge-id 2
This operation will change the configuration to default and reboot the switch.
Do you want to continue? [y/n]:y
When the confirmation question appears, answer Y.
The reply to the command will include a line about the setting of the RBridge ID.
Successfully set rbridge-id.
Changing the VCS ID
If you are going to have more than one VCS fabric, each fabric must have a unique VCS ID. The
default VCS ID for any VCS fabric is 1. Use the vcs vcs-id [ID] command to change the default VCS
ID. You should be in privileged EXEC mode to run the command. If you have made any other
configuration changes you want to persist, be sure to save your running configuration to the startup
configuration before running the vcs vcs-id command as this command reboots the switch.
Enter the vcs vcs-id [ID] command.
switch# vcs vcs-id 2
This operation will change the configuration to default and reboot the switch.
Do you want to continue? [y/n]:y
The reply to the command will include a line about the setting of the VCS ID.
Successfully set vcs-id.
Date and time on the Brocade VDX 6740
The Brocade VDX 6740 switches maintain the current date and time inside a battery-backed
real-time clock (RTC) circuit. Date and time are used for logging events. Switch operation does not
depend on the date and time; a Brocade VDX 6740 switch with an incorrect date and time value
functions properly. Because the date and time are used for logging, error detection, and
troubleshooting, you should set them correctly.
Time zones
You can set the time zone for a switch by using the clock TimeZone command. The time zone
setting has the following characteristics:
• The clock TimeZone setting automatically adjusts for Daylight Savings Time.
• Changing the time zone on a switch updates the local time zone setup and is reflected in local
time calculations.
• By default, all switches are in the Greenwich Mean Time (GMT) time zone (0,0). If all switches
in a fabric are in one time zone, it is possible for you to keep the time zone setup at the default
setting.
• System services that have already started will reflect the time zone changes only after the next
reboot.
• Time zone settings persist across failover for high availability.
• Time zone settings are not affected by Network Time Protocol (NTP) server synchronization.
The following regions are supported: Africa, America, Antarctica, Asia, Atlantic, Australia, Europe,
Indian, and Pacific. One of these, along with a city name, establishes the time zone.
Time synchronization
To keep the time in your network current, it is recommended that the principal switch has its time
synchronized with at least one external NTP server. The other switches in the fabric will
automatically take their time from the principal switch.
All switches in the fabric maintain the current clock server value in nonvolatile memory. By default,
this value is the local clock server of the principal switch. Changes to the clock server value on the
principal switch are propagated to all switches in the fabric.
When a new switch enters the fabric, the time server daemon of the principal switch sends out the
addresses of all existing clock servers and the time to the new switch.
The ntp server command accepts multiple server addresses in IPv4 format. When multiple NTP
server addresses are passed, ntp server sets the first obtainable address as the active NTP server.
If there are no reachable time servers, then the local switch time is the default time.
18Brocade VDX 6740 Hardware Reference Manual
53_1002829_02
Date and time on the Brocade VDX 6740
Synchronizing local time using NTP
Perform the following steps to synchronize the local time using NTP.
1. Log in to the switch using the default password (the default password is password).
3
2. Enter the ntp server “IPv4 address”
first NTP server in IPv4 format, which the switch must be able to access. The IPv4 address
variable is optional. By default, this value is LOCL, which uses the local clock of the principal
switch as the clock server.
switch:admin> ntp server "132.163.135.131"
To display the NTP server IP address, use the show ntp status [switchid switchid | all]
command.
switch:admin> show ntp status switchid 132.163.135.131
The request is for the local switch unless a switch ID is specified. Specify the all parameter to
send the request to all switches in the cluster.
If you need to remove an NTP server, use the no form of the ntp server command.
switch:admin> no ntp server "132.163.135.131"
command, where IPv4 address is the IP address of the
Setting the clock (date and time) manually
You should set the clock only if there are no NTP servers configured. Time synchronization from
NTP servers overrides the local clock. Date values are limited to between January 1, 1970 and
January 19, 2038.
1. Log in to the switch using the default password (the default password is password).
2. Enter the clock set year-month-dayThours:minutes:seconds command.
The following example sets the clock to March 17, 2010, 15 minutes past noon:
switch:admin > clock set 2010-03-17T12:15:00
3. To show the clock and time zone settings, use the show clock [switchid switchid | all]
command.
switch:admin > show clock switchid 1
Setting time zones
You must perform this procedure on all switches for which the time zone must be set. However, you
only need to set the time zone once on each switch, because the value is written to nonvolatile
memory. While not necessary for switch operation, setting a time zone is part of ensuring accurate
logging and audit tracking. Time zone changes take effect after a reboot.
Use the clock TimeZone command to set the time zone.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the clock TimeZone region/city command.
The following example changes the time zone to US/Pacific Standard Time:
Please refer to Table 16 for a listing of supported cables for the Brocade VDX 6740 switches.
Before plugging a cable to any port, be sure to discharge any static charge stored on the cable by
touching the electrical contacts to a grounded surface.
Ethernet or Fast Ethernet hubs
For copper connections to Ethernet hubs, a 1000Base-T switch, or another Brocade device, a
crossover cable is required. If the hub is equipped with an uplink port, it requires a straight-through
cable instead of a crossover cable.
The 802.3ab standard (automatic MDI or MDIX detection) calls for automatic negotiation of the
connection between two 1000Base-T ports. Therefore, a crossover cable may not be required; a
straight-through cable may work as well.
Workstations, servers, or routers
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 fiber
ports.
Network device
For direct attachment from the Brocade device to a Gigabit NIC, switch, or router, you can use
either a fiber cabling with an LC connector or a copper cable with an RJ-45 connector.
Testing connectivity
After you install the network cables, you can test network connectivity to other devices by observing
the LEDs related to network connection and performing trace routes. Refer to Table 3 on page 26
for a description of the port states.

Brocade inter-switch link trunks
In VCS mode, unless specifically disabled, inter-switch link (ISL) Brocade trunking between
adjacent switches is automatic. All ports must be in the same port group and must be configured at
the same speed. There is a limit of sixteen ports per trunk group. No separate licensing is required.
Refer to Figure 5 and Figure 6 below for the exact port groups. On the Brocade VDX 6740T and
Brocade VDX 6740T-1G, ports in groups 3 and 3A, as well as port groups 4 and 4A, cannot be
trunked together. However, these ports can be trunked on the Brocade VDX 6740 when the 40 GbE
QSFP ports are configured in breakout mode. Brocade VDX 6740T-1G 1GbE ports cannot be
trunked. For more information about Brocade trunking, refer to the Brocade Network OS Administrator’s Guide.

Upgrading port speeds on the Brocade VDX 6740T-1G
Using the 10G Port Upgrade License, you can enable RJ45 ports operating at 1 Gbps on the
Brocade VDX 6740T-1G switch to also operate at 10 Gbps. The license is applied in increments of
16 ports. To upgrade the ports, use the following procedure.
1. Install the PORT_10G_UPGRADE license. Use the following instructions in the Administering
Licenses chapter of the Network OS Administrator’s Guide:
2. Enter the show dpod command to verify the allowed reservation pool size and to determine
10G ports that are assigned to a 10G Port Upgrade license already.
switch# show dpod
3. Enter the configure terminal command to access global configuration mode
switch# configure terminal
4. Enter the shutdown command for the interface if not already in shutdown state.
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. Refer to Table 3 on
page 26 and Tab le 4 on page 28 for details on LED behavior.
4
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 VDX 6740 LEDs
The Brocade VDX 6740 switches have the following LEDs:
• One bicolor system status LED (green and amber) on the port side.
• One power status LED (green) on the port side.
• Two Ethernet management port LEDs (green) for the Ethernet management port. The two
LEDs show the status of the port link and the port activity.
• One triangle-shaped bicolor port status LED (green and amber) for each 10 GbE port on the
switch. These LEDs are arrayed above each vertical pair of ports on the Brocade VDX 6740.
The left LED corresponds to the upper port of the pair and the right LED corresponds to the
lower port.
• One triangle-shaped bicolor port status LED (green and amber) for each 40 GbE port on the
switch. These LEDs are arrayed between each vertical pair of 40 GbE ports on the Brocade
VDX 6740 switches. The left LED corresponds to the upper port of the pair and the right LED
corresponds to the lower port.
• One power supply and fan assembly LED (green) above the AC power switch on each combined
power supply and fan assembly on the non-port side of the switch on the Brocade VDX 6740.
• One power supply LED (green) to the left of the AC power plug on each power supply on the
non-port side of the switch on the Brocade VDX 6740T and Brocade VDX 6740T-1G.
• One bicolor fan status LED (green and amber) on each fan assembly on the non-port side of
the switch on the Brocade VDX 6740T and Brocade VDX 6740T-1G.

POST and boot specifications
When the switch is turned on or rebooted, the switch performs a power-on, self-test (POST). Total
boot time with POST can be several minutes. POST can be omitted after subsequent reboots by
using the fastboot command or entering the no diag post command to persistently disable POST.
For more information about these commands, refer to the Brocade Network OS Command Reference.
The success or failure results of the diagnostic tests that run during POST can be monitored
through LED activity, the error log, or the command line interface.
POST includes the following tasks:
• Conducts preliminary POST diagnostics.
• Initializes the operating system.
• Initializes hardware.
• Runs diagnostic tests on several functions, including circuitry, port functionality, memory,
statistics counters, and serialization.
Boot
In addition to POST, boot includes the following tasks after POST is complete:
• Performs port configuration.
• Initializes links.
• Analyzes fabric. If any ports are connected to other switches, the switch participates in a fabric
configuration.
• Obtains a domain ID and assigns port addresses.
• Constructs unicast routing tables.
• Enables normal port operation.
Interpreting POST results
POST is a system check that is performed each time the switch is powered on, rebooted, or reset.
During POST, the LEDs flash either amber or green. Any errors that occur during POST are listed in
the error log.
Complete the following steps to determine whether POST completed successfully and whether any
errors were detected.
1. Verify that the switch LEDs indicate that all components are healthy.
Refer to Ta ble 3 and Table 4 for descriptions and interpretations of LED patterns.
2. Verify that the switch prompt displays on the terminal of a computer workstation connected to
the switch.
If there is no switch prompt when POST completes, press Enter. If the switch prompt still does
not display, try opening a Telnet session or accessing the switch through another management
tool. If this is not successful, the switch did not successfully complete POST. Contact your
switch supplier for repair.
3. Review the switch system log for errors. Any errors detected during POST are written to the
system log, accessible through the show logging raslog command.
For information about all referenced commands, and on accessing the error log, refer to the
Brocade Network OS Administrator’s Guide. For information about error messages, refer to the
Brocade Network OS Message Reference.

DANGER
NOTE
Powering off the Brocade VDX 6740 switches
To power off the Brocade VDX 6740, power off both power supplies by setting each power supply
switch to O..
To power off the Brocade VDX 6740T and VDX 6740T-1G, you must unplug both power supplies.
Brocade VDX 6740 maintenance
The Brocade VDX 6740 switches are designed for high availability and low failure; they do not
require any regular physical maintenance. The SFP+ optical transceivers and diagnostic tests are
described in the following sections.
Supported transceivers
The Brocade VDX 6740 supports only Brocade-branded SFP+ optical or copper transceivers. The
Brocade VDX 6740T and Brocade VDX 6740T-1G support RJ-45 connectors for copper twisted-pair
only in the 10G Base-T ports.
4
The optical SFP+ transceivers support both Short Reach (SR) and Long Reach (LR) modules.
The Brocade VDX 6740 switches both support optical QSFP transceivers with either standard
cables or breakout (four 10 GbE connections) cables.
All fiber optic interfaces use Class 1 lasers.
Installing an SFP+ transceiver
Only the Brocade VDX 6740 supports 10 GbE SFP+ transceivers. 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 Figure 11.
3. Slide the SFP+ transceiver into the port until you feel it click into place; then close the bail.
4. Insert your cable of choice. The cable is keyed to be installed correctly.
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.
FIGURE 11Installing an SFP+ transceiver in the upper row of port slots
Diagnostic tests
In addition to POST, the Network OS includes diagnostic tests to help you troubleshoot the
hardware and firmware. This includes tests of internal connections and circuitry, fixed media, and
the transceivers and cables in use.
The tests are implemented by command, either through a Telnet session or through a console set
up to the serial connection to the switch. Some tests require the ports to be connected by external
cables, to allow diagnostics to verify the serializer/deserializer interface, transceiver, and cable.
Some tests require loopback plugs. Refer to the Brocade Network OS Administrator’s Guide and
the Brocade Network OS Command Reference Guide for more details about diagnostic tests and
commands.
Diagnostic tests run at link speeds of 1 or 10 Gbps depending on the speed of the link being tested

Before beginning the installation
The field-replaceable units (FRUs) in the Brocade VDX 6740 switches can be removed and replaced
without special tools. The switches can continue operating during the FRU replacements if the
conditions specified in the procedures are followed. switches.
Read the “Installation and safety considerations” on page 7 before servicing.

This document describes how to change field-replaceable units (FRUs) for switches with either a
port-side air exhaust or a port-side air intake. You must replace a failed FRU with a FRU of the
same type. This applies to both power supplies and fan assemblies.
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.
The P/N ends in either -F (front-to-rear airflow or exhaust) or -R (rear-to-front airflow or intake).
You must use a replacement FRU that has the same airflow designator with the part number.
The procedures in this manual are for qualified service personnel.
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 VDX 6740, MISMATCH in FAN Air Flow direction.
Replace FRU with fan air flows in same direction.
• For a power supply or combined power supply and fan mismatch: [WARNING, Brocade VDX
6740, MISMATCH in PSU-FAN FRUS Air Flow direction. Replace PSU with fan air flows in same
direction.
You can use external labels as a guide. The combined power supply and fan assemblies are labeled
with an airflow symbol on the faceplate to indicate whether the FRU 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 12 illustrates examples of the airflow labels.
FIGURE 12Examples of airflow symbols
The green E symbol indicates an exhaust FRU. This unit pulls air in from the port side of the switch
and exhausts it out the non-port side. This is called front-to-back airflow or exhaust airflow. This
symbol should appear on FRUs with part numbers ending with -F.
The orange I symbol indicates an intake FRU. This unit pulls air in from the non-port side of the
switch and exhausts it out the port side. This is called back-to-front airflow or intake airflow. This
symbol should appear on FRUs with part numbers ending with -R.

MISE EN GARDE Ce document décrit comment changer les pièces détachées des unités qui comportent un
refroidissement par une entrée ou une sortie d'air côté port. Vous devez remplacer une
pièce détachée défectueuse par une autre du même type. Cela s'applique aux blocs d'alimentation et aux ventilateurs.
La pièce détachée doit avoir la même référence que l'ancienne. La référence du fabricant
se trouve sur le dessus de la pièce détachée.
La référence se termine par -F (flux d'air de l'avant vers l'arrière) ou par -R (flux d'air de
l'arrière vers l'avant). Vous devez utiliser une pièce détachée dont l'indicatif de flux d'air est
le même.
PRECAUCIÓN Este documento describe cómo cambiar las unidades reemplazables sobre el terreno
(FRU, por sus siglas en inglés) por unidades con salida o entrada de aire por el lado de los
puertos. La unidad FRU averiada debe cambiarse por otra del mismo tipo. Esto aplica a las
fuentes de alimentación y a los módulos de ventilación.
La nueva unidad FRU debe tener el mismo número de parte (P/N) que la unidad FRU que
se va a sustituir. El P/N de fabricación se encuentra en la parte superior de la unidad FRU.
El P/N termina en -F (flujo de aire de adelante hacia atrás) o -R (de atrás hacia adelante).
