Brocade 6520 overview

The Brocade 6520 is a 96-port auto-sensing 2, 4, 8, or 16 Gbps, as well as 10 Gbps, Fibre Channel (FC) switch that delivers the latest Brocade multi-chip architecture for Fibre Channel Storage Area Networks (SANs). The Brocade 6520 is an enterprise-class switch that is designed to handle the large-scale SAN requirements of an enterprise, and can also be used to address the SAN requirements of a small to medium-sized workgroup.

The Brocade 6520 provides up to 96 ports in a double height (2U) switch that enables the creation of very dense fabrics in a relatively small space.

The Brocade 6520 offers Ports on Demand (POD) licensing as well. “Base” models of the switch contain 48 ports, and up to two additional 24-port POD licenses can be purchased to fill all 96 ports.

Port activation works through a process called Dynamic Ports on Demand (DPOD). With DPOD, ports are licensed as they come online. For instance, if you have a base model with 48 port licenses, the first 48 ports to come online, regardless of their numbering, are licensed. Once all the licenses have been assigned, you can manually move those licenses from one port to another if you choose.

The first eight ports can be configured to run at 10 Gbps with the appropriate licensing.

The Brocade 6520 supplies Reliability, Availability, and Serviceability (RAS) performance and scalability requirements of an enterprise switch along with interoperability and ease-of-use advantages.

The Brocade 6520 is only 24 inches deep and has airflow direction options. You can order either port side exhaust (the default configuration) or non-port side exhaust airflow to accommodate specific installations.

Brocade 6520 features and capabilities

The Brocade 6520 offers the following features and capabilities:

•Up to 96 auto-sensing ports of high-performance 16 Gbps technology in a single domain.

•Ports on Demand scaling from 48 to 72 or 96 ports.

•Port licensing via DPOD

2 Installation and safety considerations

Environmental considerations

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

•At a minimum, adequate cooling requires that you install the switch with the intake side, as indicated by the airflow direction of the fan assemblies, facing the cool-air aisle.

The chassisshow output indicates “Reverse” for non-port side intake and “Forward” for port side intake.

•All equipment in the rack should force air in the same direction to avoid intake of exhaust air.

•Airflow requirements outlined in Table 5 must be met. Note that the requirements differ based on the direction of the airflow.

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

Table 5 lists the acceptable environmental ranges for both operating and nonoperating (such as during transportation or storage) conditions.

TABLE 5	Environmental requirements
Condition		Acceptable during operation	Acceptable during non-operation
Ambient		0º to 40ºC (32º to 104ºF)	-25º to 70ºC (-13º to 158ºF)

		Nominal - 56.1 cmh (33 cfm)
Heat dissipation		1378.5 BTU/hr (no optics configuration)	N/A
		1706.1 BTU/hr (fully populated port
		configuration)

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.

•A rack space that is two rack units (2U) high; 8.90 cm (3.50 inches) high and 48.3 cm (19 inches) wide.

•There are three rack kit options that accommodate the Brocade 6520, a four-post fixed rack kit, a two-post Telco rack kit, and a four-post sliding rail rack kit. See their respective installation manuals for details.

	53-1002705-02

Installation and safety considerations

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.

•Airflow and temperature requirements are met on an ongoing basis, particularly if the switch is installed in a closed or multirack assembly.

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

NOTE

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

•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.

•If you are using Brocade ISL Trunking, consider grouping cables by trunking groups. The cables used in trunking groups must meet specific requirements, as described in the Fabric OS Administrator’s Guide.

•For easier maintenance, label the fiber-optic cables and record the devices to which they are connected.

•Keep LEDs visible by routing port cables and other cables away from the LEDs.

•Use Velcro-style straps to secure and organize fiber-optic cables.

Items required for installation

The following items are required for installing, configuring, and connecting the Brocade 6520 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

•Items from the accessory kit that accompanies the switch

•Ethernet cable

•Brocade-branded SFP+s transceivers and compatible cables (Brocade-branded 16 Gbps SFP+s transceivers required for 16 Gbps performance), as required

•Access to an FTP server or USB device for backing up the switch configuration (optional)
