ExtremeSwitching VDX 6740 Hardware Installation Guide

Product Overview

• Product features.................................................................................................................................................................................................13

• Hardware components....................................................................................................................................................................................18

Product features

The ExtremeSwitching VDX 6740 product family includes three top-of-rack, Gigabit Ethernet (GbE) line-rate, low latency, lossless Data Center Bridging (DCB) devices:

The VDX 6740 has the following features:

• Base models support 24 Ethernet ports. A 10G Port Upgrade license can add ports in increments of 8, 16, and 24 ports, for a total of 48 Ethernet ports. The following types of optics can be installed in these ports:

– 1/10 GbE ports operating at 1 Gbps, 10 Gbps, or in auto-sensing mode (1 or 10 Gbps). – 1 GbE copper optics, operating at 1 Gbps and 100 Mbps. – 8 Gbps Fibre channel optics operating at 2, 4, and 8 Gbps and 16 Gbps optics operating at 4, 8, and 16 Gbps when the

FlexPort feature is used.

• Base models do not support 40 GbE ports, but a 40G Port Upgrade license can add two or four 40 GbE ports. Only 4x10 GbE QSFP+ optics can be installed in these ports as FlexPort is not supported on the 40 GbE ports.

The VDX 6740T has the following features:

• Base models support 24 Ethernet ports. A 10G Port Upgrade license can add ports in increments of 8, 16, and 24 ports, for a total of 48 Ethernet ports. These ports support Base-T (RJ-45) transceivers operating at 100 Mbps, 1 Gbps, 10 Gbps, or in auto-sensing mode.

• Base models do not contain 40 GbE ports, but a 40G Port Upgrade license can add two or four 40 GbE ports. These ports support the following optics:

– 40 GbE optics – 4x10 GbE QSFP+ optics. – 4x16 Fibre Channel QSFP+ optics if the FlexPort feature is used. Fibre Channel operation is supported on 40-GbE ports

congured in SFP breakout mode (also referred to as 4x10 GbE breakout mode) that use qualied 4x16 Fibre Channel QSFP+ optics.

The VDX 6740T-1G variant has the following features:

• Base models are fully populated with 48 Ethernet ports. These ports support Base-T (RJ-45) transceivers operating at 100 Mbps, 1 Gbps, or in auto-sensing mode. A 10G Port Upgrade license enables port operation at 100 Mbps, 1 Gbps, 10 Gbps, or in auto-sensing mode. This upgrade can be installed in increments of 16, 32, and 48 ports.

• Base models contain two 40 GbE ports. A 40G Port Upgrade license can be added for two additional 40 GbE ports. These ports support the following optics:

– 40 GbE optics – 4x10 GbE QSFP+ optics. – 4x16 Fibre Channel QSFP+ optics if the FlexPort feature is used. Fibre Channel operation is supported on 40-GbE ports

congured in 40 GbE mode that use qualied 4x16 Fibre Channel QSFP+ optics.

For all models, the 40 GbE port can be recongured as four 10 GbE ports in SFP breakout mode (also referred to as 4x10 GbE breakout mode). Thus, the device can be congured with as many as 64 10 GbE ports. For instructions on conguring breakout mode, refer to the "SFP breakout" section of the Extreme Network OS Management Conguration Guide.

ExtremeSwitching VDX 6740 Hardware Installation Guide 9036108-00 13

Product features

The VDX 6740 devices run on the Extreme Network OS v4.0.0 or later. The 100 Mbps speed for Base-T ports on the VDX 6740T is available with Extreme Network OS v4.1.0 and later. For details about Extreme Network OS, refer to the Extreme Network OS Management Conguration Guide.

A key feature of this device is ExtremeSwitching VCS™ technology, which includes virtual cluster switching, a set of technologies that allows users to create atter, virtualize, and converged data center networks. VCS fabrics are scalable, permitting users to expand at their own pace, and simplied, allowing users to manage the fabric as a single entity. VCS-based Ethernet fabrics are convergence-capable with technologies such as Fibre Channel over Ethernet (FCoE) for storage.

This device can also be deployed in IP fabrics. An IP fabric can be described as a collection of discrete Layer 3 elements (such as switchrouters) arranged in a spine-leaf network. These elements exchange Layer 2 and Layer 3 database information to provide a exible, non- blocking and scalable framework while retaining the semantics of a single logical switch. There can be competing protocols for exchanging this distributed database across such discrete elements. Spine-leaf networks are designed to be a three-stage architecture, an ingress stage, a middle stage, and an egress stage. The concept is that there are multiple paths for the call to be switched through the network so that trac can always connect and not be blocked. For full details and conguration procedures for IP fabrics, refer to the Extreme Network OS IP Fabrics Conguration Guide.

FlexPort

The FlexPort feature is supported on the VDX 6740 with Network OS 5.0.0 and later and on the VDX 6740T with Network OS 6.0.0 and later. This feature allows you to attach a FC device to run encapsulated FC over Ethernet (FCOE)

trac through the device.

To congure FlexPort and Fibre Channel operation for specic VDX 6740 ports, follow steps in the "FlexPort" section of the Network OS Management Conguration Guide.

FlexPort allows you to congure specic groups of ports, called connector groups, as 10 Gbps Ethernet ports or as Fibre Channel (FC) ports. Up to 32 ports can be congured as FlexPorts. These ports can be changed from Ethernet to Fibre Channel operation without a reboot. Qualied 10 GbE SFP+ transceivers or 4x10 GbE breakout cables must be installed to allow Ethernet operation. Qualied 8 Gbps FC, 16 Gbps FC, or 4x16G QSFP+ transceivers must be installed to allow Fibre Channel operation.

Connector groups share common speed and protocol type properties. You can congure the following speed and protocol combinations in each connector group:

• LowMixed - 2, 4, and 8 Gbps FC and 1/10 Gbps Ethernet

• HighMixed - 16 Gbps FC and 10 Gbps Ethernet only

• FibreChannel - 2, 4, 8, and 16 Gbps FC (no Ethernet)

For the VDX 6740T, Ethernet operation is supported on 40 GbE QSFP ports congured in 40 GbE mode that use qualied 40 GbE transceivers and on 40 GbE ports in SFP breakout mode (also referred to as 4x10 GbE breakout mode) that use qualied 4x10 GbE QSFP transceivers. Fibre Channel operation is supported on 40 GbE ports congured in SFP breakout mode that use qualied 4x16 QSFP+ transceivers. FlexPort is not supported on 40 GbE QSFP ports on the VDX 6740.

The default port FlexPort setting is Ethernet. Consider the following for Fibre Channel operation and ISL connections:

• Ports that do not support the Fibre Channel protocol are not allowed to have their connector group setting changed from the default setting.

• When the system is booted up, by default, a FlexPort can become an ISL port because it is an Ethernet port in no-shut state. However, if the FlexPort is congured as FC port, it won't become an ISL port.

For details on the FlexPort feature, including port ranges on VDX 6740 models that can be congured as FlexPorts, connector groups, and conguration procedures, refer to the Network OS Management Conguration Guide.

Using the VDX 6740T as a DHCP server

You can connect the VDX 6740T to the management port on any Extreme Networks switch (DHCP client) and use the VDX 6740T as a DHCP server to support DHCP Automatic Deployment (DAD), DHCP zero touch provisioning (ZTP), obtaining switch IP addresses, and other services.

The following steps provide an example for connecting a VDX 6740T as a DHCP server to a VDX 6740 functioning as the DHCP client.

• Connect the VDX 6740T Ethernet management port to any of the VDX 6740T inband 10 GbE BaseT ports using a CAT5 cable.

• Connect the VDX 6740 Ethernet management port to any of the 10 GbE ports on the VDX 6740T using a CAT5 cable.

4. VDX 6740T

5. VDX 6740

Following are general steps to congure the VDX 6740T as a DHCP server. For detailed procedures and Fabric OS commands, refer to the Extreme Network OS Management Conguration Guide.

• Set up the DHCP pool address and other parameters in the dhcp.conf le.

• Congure a static IP address for the management port (DHCP must be disabled), then enable DHCP on the port.

• Congure the VDX 6740T inband ports that you are using for DHCP server connections into a VLAN so that the client switches can obtain DHCP IP addresses from the server.

• Download the dhcpd.conf le to the VDX 6740T. A valid dhcpd.conf le must be copied into the device before enabling the DHCP server.

Following are requirements and considerations for this feature:

• VDX 6740T is supported as the DHCP server and connected Extreme Networks switch is supported as a DHCP client.

• DHCP server must run as a standalone switch; it cannot be enabled when the switch is part of a VCS cluster.

• DHCPv6 is not supported.

• DHCP server can support up to 20 clients.

• DHCP server is not supported on inband ports without IP loopback and DHCP server support on the management port.

• DHCP conguration with a multiple subnet is not supported.

• DHCP only runs on the active CP. HA failover is supported.

ExtremeSwitching VDX 6740 Hardware Installation Guide 9036108-00 15

Product features

• "DHCP relay" must be disabled since the DHCP server uses the same port number. Enabling and disabling DHCP automatically toggles "dhcp relay" and forces a switch reboot.

Extreme Networks inter-switch link trunks

In VCS mode, unless specically disabled, inter-switch link (ISL) Extreme Networks trunking between adjacent devices is automatic. All ports must be in the same port group and must be congured at the same speed. There is a limit of sixteen ports per trunk group. No separate licensing is required. Refer to the illustrations below for the exact port groups. On the VDX 6740T, 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 VDX 6740 when the 40 GbE QSFP ports are congured in breakout mode. VDX 6740T 1GbE ports cannot be trunked.

NOTE

If connections are made to 16 dierent switches, only eight ports will be trunk ports while the other eight ports will be normal ISL ports.

For instructions on conguring breakout mode and Extreme Networks trunking, refer to the Extreme Network OS Management Conguration Guide.

Supported transceivers

The VDX 6740 provides up to 48 ports that support 1, 8, or 10 GbE optical SFP+ Extreme-branded Ethernet SFP+ optical or copper transceivers. These ports also support SFP+ direct-attached Twinax copper and active and passive optical cables.

VDX 6740 ports also support 10 GbE tunable SFP+ (TSFP+) transceivers. If used, TSFP+ transceivers must be installed in the port at each end of a link and "tuned" to the same wavelength. If not, the link may come online, but operation may be unpredictable. If wavelength dierence exceeds a specied limit, a RASLOG message occurs and the port is taken oine. You can congure wavelengths for installed transceivers using channel numbers from 1 to 102 that correspond to wavelengths from 1568.77 to 1528.38 nm using the tunable-optics sfpp channel channel number command. For details on using this and related commands, refer to the "Tunable SFP+ optics" section of the Extreme Network OS Management Conguration Guide.

The VDX 6740T provides 48 ports with 10G Base-T RJ-45 connectors for copper twisted-pair only.

Both the VDX 6740 and VDX 6740T provide four ports that support 40 GbE QSFP+ transceivers. These ports support SFP breakout mode (also referred to 4x10 GbE breakout mode) using 4x10 GbE breakout cables. Fibre Channel FlexPort operation is supported only when ports are in 40 GbE mode using optical 4x16G QSFP+ short wavelength transceivers. On the VDX 6740T, the 40 GbE ports also support 10 GbE SFP+ transceivers when the QSA Adapter is used.

For details on supported transceivers for all VDX 6940 models, refer to the ExtremeSwitching VDX Transceiver Support Matrix.

ExtremeSwitching VDX 6740 Hardware Installation Guide 9036108-00 25

Installation and safety considerations

Environmental precautions

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

• Fans supplied with the device move air either front to back (exhaust) or back to front (intake). Be sure to align the device with the airow 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.

CAUTION Ensure that the airow 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."

• Ensure that the airow available at intake vents allows the maximum airow as specied in the product Technical Specications.

• Ensure that the ambient air temperature does not exceed that specied for maximum operational temperate in the product Technical Specications.

EIA rack considerations

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

• The rack must be a standard EIA rack.

• For 1U devices, the rack space required is one rack unit (1U) 44.45 mm (1.75 in.) high and 440 mm (17.5 in.) wide.

• 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 airow or negatively aect temperature requirements, particularly if the device is installed in a closed or multirack assembly. Ensure that airow openings on the port and nonport side of the device are not obstructed.

CAUTION Make sure the airow around the front, and back of the device is not restricted.

• The additional weight of the device 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.

DANGER

Make sure the rack housing the device is adequately secured to prevent it from becoming unstable or falling over.

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 EIA rack or patch panels to reduce the potential for tangling the cables. The following list provides some recommendations for cable management:

26 9036108-00

ExtremeSwitching VDX 6740 Hardware Installation Guide

Items included with the device

NOTE

You should not use tie wraps with optical cables because they are easily overtightened and can damage the optic bers. Velcrolike wraps are recommended.

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

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