Footnote 1: When ordering FRUs, verify that the part number supports the correct airflow.You must replace a failed unit with the same type of unit. 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 back airflow) or R (back/rear to front airflow) You must The P/N ends in either -F (front-to-back airflow) or -R (back/rear-to-front airflow). You must use a replacement FRU that the same airflow designator with the part number.

Additionally, you can use external labels as a guide. Some 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 assembly.

Footnote 1: An FCoE license enables FCoE on the Brocade VDX 6720 platforms. Since FCoErequires a VCS fabric, a VCS Fabric license is a prerequisite for enabling FCoE in a fabric with more than two switches. In addition, a separate FCoE license is required to enable FCoE on a VCS edge port. Without an FCoE license, FCoE logins are not permitted, and all FCoE commands with the exception of a few commands return an error of “No FCoE license present” when executed.

Footnote 2: A Dynamic POD license allows you to instantly scale the fabric by provisioning additional ports on the Brocade VDX 6720 platforms. Licenses are assigned dynamically from a pool of resources based on auto-detection of active links.

3 - 16Revision 0111


Note: For the VDX 6720-24, ports 1 through 16 are enabled by default. For the POD license, ports 17 through 24 are enabled.

For the VDX 6720-60, the bottom row of ports, 1 through 40, are enabled by default. For the first POD license, ports 41 through 50 are enabled. For the second POD license, ports 51 to 60 are enabled.

Footnote 1: The management port 10/100/1000 Ethernet (RJ-45) includes two LEDs: link and activity. For link, on indicates link is active, off indicates no link. For Activity, blinking indicates activity and off indicates no activity.

RLOM: Not supported in this release

The serial port parameters are fixed at the following: • 9600 baud• 8 data bits• No parity• No hardware flow controlNo hardware flow control

The USB port is used for Brocade branded-USB drives which are used for firmware download and storing support information such as logs.

Footnote 1:• Switching bandwidth from switch backplane (data rate at full duplex):

– 6720-24: 480 Gbps– 6720-60: 1200 Gbps

• Forwarding bandwidth from ports (data rate at full duplex):– 6720-24: 358 Mpps (Million packets per second: used in measuring forwarding rate pp ( p p g g

and forwarding bandwidth)– 6720-60: 896 Mpps

• Port-to-port latency: – 600 ns

As shown above, VDX 6720-24 platform contains one eAnvil2 ASIC. Each eAnvil2 ASIC supports a Routing Engine (RTE) and each RTE supports 24-1 or 10 Gbps Ethernet ports. Every packet coming in through the external SFP+ interfaces destined to external ports are switched in a single stage within the eAnvil2 ASIC.

The data path is also applicable to packets originated by the CPU which need to go out of the network ports.

The latency for port-to-port communication is 600ns .

3 - 23Revision 0111


The six front facing eAnvil2 ASICs support local switching. For example, if port 1 needs to send the data to port 2, the packet can be switched locally within a single eAnvil2 ASIC and does not require inter-ASIC switching

Unlike the VDX 6720-24 design, the incoming packets on SFP+ ports destined to an external port now go through three different eAnvil2 ASICs if the source and destination port are on diff A il2 ASICdifferent eAnvil2 ASICs

Footnote 1: The following items are required for configuring and connecting the VDX for use in a network and fabric:• VDX installed and connected to a power source• Workstation with an installed terminal emulator, such as HyperTerminal• Two unused IP addresses and corresponding subnet masks and gateway addresses.

(One for the virtual IP address on the cluster interconnect and another for the management port.)

• Serial cable (provided)• Three Ethernet cables• SFPs and compatible cables, as required• Access to an FTP server for backing up the switch configuration (optional)• A USB stick for collecting the support data (optional). Only those commands supported

by Network OS, such as copy support-interactive. Refer to the troubleshooting module later in this course for specific commands and their usage.

Footnote 2: Follow the installation instructions shipped with the applicable rack mount kit.

Footnote 3: When mounting into a slide-rail rack, you can mount the chassis to slide from either the port side or the non-port side.

Footnote 1: On the non-port side of the switch enclosure, each power supply/Fan FRU has a green/amber LED to indicate the status of the FRU. A steady green light indicates that the FRU is on and operating normally. If there is an amber light, the power is faulty.

Footnote 1: The three fan FRUs are designed as hot-swappable in a redundant N+1 configuration to ensure that the VDX 6720-60 continues to operate indefinitely and non-disruptively in the event of a single fan FRU failure.

Footnote 2: On the non-port side of the switch enclosure, each fan FRU has a green/amber LED to indicate the status of the FRU. A steady green light indicates that the FRU is on and operating normally. If off, then there is no AC power. If there is an amber light, the fan is faulty. If off, then that indicates normal operations.
