Brocade VDX6720 overview

The Brocade VDX6720 family is a set of 10 GbE line-rate, low latency, lossless Data Center Bridging
(DCB) switches that comes in two forms. These include a 24-port, single height version
(VDX6720-24) and a 60-port double height version (VDX6720-60). The Brocade VDX6720s run on
Brocade’s new Network Operating System (Network OS) v2.0.0. Network OS is high-performance,
scalable, feature-rich, and designed to integrate with Brocade's data center switching products. For
details about the Network OS, please see the Brocade Network OS Administrator’s Guide.

A key feature with the Brocade VDX6720 family is Brocade Virtual Cluster Switching (VCS), a new
set of technologies that allows users to create flatter, virtualized, and converged data center
networks. VCS is scalable, permitting users to expand at their own pace and simplified, allowing
users to manage the network as a single entity. VCS-based Ethernet fabrics are convergence
capable, enabling Fibre Channel over Ethernet (FCoE) storage.

1

The Brocade VDX6720 family also features Remote Lights Out (RLO) management and Keep Alive
Processing (KAP) in an auxiliary CPU subsystem. RLO provides remote access capability when
physical access is not possible or is difficult. RLO permits a remote user to perform tasks such as
switch reset and power cycling. KAP generates DCB L2 and FCoE protocol frames during hot code
loads so that the switch does not time out during a firmware upgrade.

The Brocade VDX6720 family offers Ports-on-Demand (POD) licensing as well. “Base” models of
the switches contain 16 (for the VDX6720-24) or 40 (for the VDX6720-60) ports. Additional ports
can be licensed via POD. One POD license on the VDX6720-24 allows the additional eight ports to
be activated. For the VDX6720-60, two POD licenses (for ten ports each) can be purchased.

Platform components and capabilities

The Brocade VDX6720 family offers the following common features and capabilities:

A system motherboard that features a Freescale MPC8548 Reduced Instruction Set Computer
(RISC) CPU running at 1.3 GHz with integrated peripherals

An auxiliary 405EX processor to support Keep Alive Processing (KAP) and Remote Lights Out
Management (RLO)

An RJ45 10/100/1000 Ethernet out-of-band management port

An RJ45 10/100/1000 Ethernet port for RLO

Electrical considerations

To install and operate the switch successfully, ensure the following:

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 provided in Table 9, “Power Supply Specifications” are met.

Environmental considerations

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

Because the Brocade VDX6720 can be ordered with fans that either move air 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.

A maximum of 102 cubic meters/hour (60 cubic feet/minute) and a minimum of 74.8
cubic meters/hour (44 cubic feet/minute) of air flow is available to the air intake vents.

The ambient air temperature does not exceed 40° C (104° F) while the switch is operating.

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.

A cabinet space that is one rack unit (1U for VDX6720-24) or two rack units (2U for
VDX6720-60) high depending on the platform ordered; 4.45 cm (1.75 inches) or 8.90 cm
(3.50 inches) high and 48.3 cm (19 inches) wide.

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

The minimum bend radius for a 50 micron cable is 2 inches under full tensile load and 1.2 inches
with no tensile load.

•

•

•

•

•

•

•

•

Cables can be organized and managed in a variety of ways, for example, using cable channels on
the sides of the cabinet or patch panels to minimize cable management. Following is a list of
recommendations:

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 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 VDX6720
for use in a network and fabric:

Workstation with an installed terminal emulator, such as HyperTerminal

Unused IP address and corresponding subnet mask and gateway address

Serial cable (provided)

Ethernet cable

Brocade-branded SFP (1GbE) or SFP+s (10GbE) and compatible cables and/or
direct-attach copper and optical cables

Access to an FTP server for backing up the switch configuration (optional)

Standalone installation for a Brocade VDX6720

Perform this task to install the Brocade VDX6720 as a standalone unit.

1. Unpack the Brocade VDX6720 and verify the items listed on

VDX6720” on page 7. Verify the items are present and undamaged.

2. Apply the adhesive rubber feet. Applying the rubber feet onto 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.

ATTENTION

Do not connect the switch to the network until the IP address is correctly set. For instructions on how
to set the IP address, see “Configuring the Brocade VDX6720”

Cabinet installation for a Brocade VDX6720

Follow the installation instructions shipped with the appropriate rack mount kit:

To install the switch into a fixed-rail rack, refer to the Fixed Rack Mount Kit Installation
Procedure.

To install the switch into mid-mount rack, refer to the Mid-Mount Rack Mount Kit (Switch)
Installation Procedure.

Providing power to the switch

Perform the following steps to provide power to the Brocade VDX6720.

1. Connect the power cords to both power supplies, and then to power sources on separate
circuits to protect against AC failure. Ensure that the cords have a minimum service loop of 6
in. available and are routed to avoid stress.

2. Power on the power supplies by flipping both AC switches to the “I” symbol (VDX6720-24 only,
power supplies for VDX6720-60 power up automatically when plugged in). The power supply
LEDs display amber until POST is complete, and then change to green. The switch usually
requires several minutes to boot and complete POST.

Power is supplied to the switch as soon as the first power supply is connected and turned on.

3. After POST is complete, verify that the switch power and status LEDs on the left of the port side
of the switch are green. See Figure 5 for the specific location of these LEDs.

Configuring the Brocade VDX6720

Something about the ease of configuring the switch and the automatic formation of the Ethernet
fabric when VCS is enabled.

Creating a serial connection

You will perform all configuration tasks in this guide using a serial connection.

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.

3

If the serial port on the workstation 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:

Bits per second 9600

Databits 8

Parity None

Stop bits 1

Flow control None

In a UNIX environment using TIP, enter the following string at the prompt:

Switch IP address

You can configure the Brocade VDX6720 with a static IP address, or you can use a DHCP (Dynamic
Host Configuration Protocol) server to set the IP address of the switch. DHCP is enabled by default.
The Brocade VDX6720 supports both IPv4 and IPv6.

Using DHCP to set the IP address

When using DHCP, the Brocade VDX6720 obtains its 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
VDX6720, use a static IP address.

Setting a static IP address

1. Log into the switch using the default password, which is password.

2. Use the i

If you are going to use an IPv4 IP address, enter the IP address in dotted decimal notation as
prompted.

Ethernet IP Address: [192.168.74.102]

If you are going to use an IPv6 address, enter the network information in semicolon-separated
notation as prompted.

switch:admin> ipaddrset -ipv6 --add 1080::8:800:200C:417A/64

command to set the Ethernet IP address.

Date and time settings

The Brocade VDX6720 maintains 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 VDX6720 with an incorrect date and time value still functions properly.
However, 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 the switch by name. You can also set country, city or time zone
parameters.

If the time zone is not set with the new options, the switch retains the offset time zone settings. The

Local time synchronization

You can synchronize the local time of the principal or primary fabric configuration server (FCS)
switch to a maximum of eight external network time protocol (NTP) ser vers. To keep the time in your
SAN current, it is recommended that the principal or primary FCS 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 or primary FCS switch.

All switches in the fabric maintain the current clock server value in non-volatile memory. By default,
this value is the local clock server <LOCL> of the principal or primary FCS switch. Changes to the
clock server value on the principal or primary FCS switch are propagated to all switches in the
fabric.

When a new switch enters the fabric, the time server daemon of the principal or primary FCS switch
sends out the addresses of all existing clock servers and the time to the new switch. If a switch with
v5.3.0 or later has entered the fabric it will be able to store the list and the active servers; pre-5.3.0
Fabric OS switches will ignore the new list parameter in the payload and will update only the active
server address.

If the active NTP server configured is IPv6, then distributing the same in the fabric will not be
possible to switches earlier than v5.3.0 because IPv6 is supported for Fabric OS version 5.3.0 and
later. The default value LOCL will be distributed to pre-5.3.0 switches.

Complete the following steps to power the Brocade VDX6720 on.

1. Connect one or both power cords to the power connectors on the power supplies and to a
power source

2. Set the AC power switches to “I” for the VDX6720-24. The power supplies for the VDX6720-60
power on when they are plugged in.

Power is supplied to the switch as soon as the first power supply is connected and powered on.

The switch runs POST by default each time it is powered on; it can take up to several minutes to
boot and complete POST.

To power the Brocade VDX6720 off, power off both power supplies by setting each AC power switch
to “O” for the VDX6720-24 or unplugging the power supplies for the VDX6720-60. All devices are
returned to their initial state the next time the switch is powered on.

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: no light, a steady light, and a flashing light. Flashing lights may
be slow, fast, or flickering. The lights are green or amber. See Table 1 for details on LED behavior.

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 VDX6720 LEDs

The Brocade VDX6720 has the following LEDs:

statistics counters, and serialization.

Boot

In addition to POST, boot includes the following tasks after POST is complete:

1. Performs universal port configuration.

2. Initializes links.

3. Analyzes fabric. If any ports are connected to other switches, the switch participates in a fabric
configuration.

4. Obtains a domain ID and assigns port addresses.

5. Constructs unicast routing tables.

6. Enables normal port operation.

Interpreting POST results

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.

See

Tab le 1 and Table 2 for descriptions and interpretations of LED patterns. If one or more

LEDs do not display a healthy state, verify that the LEDs on the switch are not set to “beacon”
by entering the s

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 E
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 e

Diagnostic tests

In addition to POST, Fabric 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.

Diagnostic tests run at link speeds of
the speed of the link being tested and the type of port.

Diagnostic tests might temporarily lock the transmit and receive speed of the links during diagnostic
testing.

Brocade VDX6720 Management

You can use the management functions built into the Brocade VDX6720 to monitor the fabric
topology, port status, physical status, and other information to help you analyze switch
performance and to accelerate system debugging.

The Brocade VDX6720 automatically performs power-on self-test (POST) each time it is turned on.
Any errors are recorded in the system error log. For more information about POST, see “POST and

boot specifications” on page 22.

For information about upgrading the version of Network OS installed on your switch, see the

Brocade Network OS Administrator’s Guide.

You can manage the Brocade VDX6720 using any of the management options listed in Table 3 .
Note that if you use the command line interface, there are two sets of CLI commands, one for the
Fibre Channel features and one for the Data Center Bridging (DCB) features. Please refer to the
Brocade Network OS Administrator’s Guide for more information on the respective CLI commands.

Introduction

Read the “Installation and safety considerations” before servicing.

The field replaceable units (FRUs) in the Brocade VDX6720 family of switches can be removed and
replaced without special tools. The switches can continue operating during the FRU replacements
if the conditions specified in the procedure are followed.

5

The following sections contain FRU removal and replacement procedures (RRPs).

Before beginning the installation

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, VDX6720, MISMATCH in FAN Air Flow direction. Replace FRU
with fan air flows in same direction.

Additionally, you can use external labels as a guide. The FRUs 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.
