Brocade VDX 6720/6730 overview
The Brocade VDX 6720/6730 switches are a pair of 10 GbE line-rate, low latency, lossless Data Center
Bridging (DCB) switches: the VDX 6720/6730-24 (a 24-port, single height switch) and the VDX 6720-60
(a 60-port double height switch). The Brocade VDX 6720/6730 switches run on the Brocade Network
Operating System (Network OS) v2.0.0. For details about Network OS, refer to the Brocade Network
OS Administrator’s Guide.
A key feature of the Brocade VDX 6720/6730 switches is Brocade VCS™ technology, which includes
virtual cluster switching, a new set of technologies that allows users to create flatter, virtualized,
and converged data center networks. VCS fabrics are scalable, permitting users to expand at their
own pace, and simplified to allow users to manage the fabric as a single entity. VCS-based Ethernet
fabrics are convergence-capable, enabling Fibre Channel over Ethernet (FCoE) storage.
The Brocade VDX 6720/6730 switches offer Ports on Demand (POD) licensing as well. “Base” models of
the switches contain 16 ports (for the VDX 6720-24) or 40 ports (for the VDX 6720-60). Additional
ports can be licensed via POD. One POD license on the VDX 6720-24 allows the additional 8 ports
to be activated. For the VDX 6720-60, two POD licenses (for 10 ports each) can be purchased.

Items included with the Brocade VDX 6720/6730 switches
The following items are included with the standard shipment of a fully-configured Brocade VDX
6720. When you open the Brocade VDX 6720 packaging, verify that the items are included in the
package and that no damage has occurred during shipping.
•The Brocade VDX 6720 switch, either the 24-port or 60-port version
•One accessory kit, containing the following items:
-Serial cable with an RJ45 connector
-6 ft. power cords
-Rubber feet, required for setting up the switch as a standalone unit
-Brocade Family Documentation CD
-Brocade VDX 6720/6730 QuickStart Guide
Installation and safety considerations
You can install a Brocade VDX 6720 switch in the following ways:
•As a standalone unit on a flat surface.
•In an EIA cabinet using a fixed-rail rack mount kit. The optional fixed-rail rack mount kit can be
ordered from your switch retailer.
•In an Telco rack using an flush mount rack kit. The optional flush mount rack kit for switches
can be ordered from your switch retailer.
•In the Idataplex IBM 17-inch depth rack (requires an Idataplex rack mount kit).
Electrical considerations
To install and operate the switch successfully, ensure compliance with the following requirements:

8Brocade VDX 6720/6730 Hardware Reference Manual
53-1002084-01
Installation and safety considerations
2
•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 are met. Refer to Table 10 on page 40, 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 6720/6730 switches 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 airflow 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.
•The cabinet space is one rack unit or two rack units high depending on the platform ordered
(1U for VDX 6720-24 or 2U for VDX 6720-60); 4.45 cm (1.75 in.) or 8.90 cm (3.50 in.) high and
48.3 cm (19 in.) wide.
•The equipment in the cabinet 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 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 5.1 cm (2 in.) under full tensile load and 3.0 cm
(1.2 in.) with no tensile load.
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:
