Brocade VDX 6740 overview

The Brocade VDX 6740 switches are top-of-rack, Gigabit Ethernet (GbE) line-rate, low latency, lossless Data Center Bridging (DCB) switches:
The Brocade VDX 6740 offers SFP+ ports for its 1/10 GbE interfaces. Base models contain 24
Ethernet ports operating at 1 Gbps, 10 Gbps, or in auto-sensing mode. A 10G Port Upgrade license can add 1/10G ports in increments of 8, 16, and 24 ports. A 40G Port Upgrade license can be added for either two or four 40 GbE ports.
The Brocade VDX 6740T offers 1/10G Base-T (RJ-45) ports and additional 40 GbE QSFP ports.
Base models contain 24 Ethernet ports operating at 100 Mbps, 1 Gbps, 10 Gbps, or in auto-sensing mode. A 10G Port Upgrade license can add ports in increments of 8, 16, and 24 ports. A 40G Port Upgrade license can be added for either two or four 40 GbE ports.
The Brocade VDX 6740T-1G offers 1G Base-T (RJ-45) ports and additional 40 GbE QSFP ports.
Base models are fully populated with 48 Base-T ports operating at 100 Mbps, 1 Gbps, or in auto-sensing mode. A 10G Port Upgrade license enables RJ-45 port operation at 10 Gbps. This license can be applied in increments of 16, 32, and 48 ports. The Brocade VDX 6740T-1G ships standard with two 40 GbE ports. A 40G Port Upgrade license can be added for two additional 40 GbE ports.
Each 40 GbE port can be reconfigured as four 10 GbE ports in QSFP breakout mode. Thus, the Brocade VDX 6740 switches can be configured with as many as 64 10 GbE ports.

Installation and safety considerations
NOTE
DANGER
2
For the Brocade VDX 6740T and Brocade VDX 6740T-1G:
- In a four-post EIA rack using a port-side flush mount or a non-port-side flush mount
universal fixed-rail rack mount kit.
- In a Telco rack using a port-side flush mount or mid-mount universal rack kit.
For the Brocade VDX 6740T and Brocade VDX 6740T-1G, be sure to keep the vents on the sides near the front of the switch are unobstructed.
The procedures in this manual are for qualified service personnel.

Electrical considerations

To install and operate the switch successfully, ensure compliance with the following requirements:
The primary outlets are 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 12 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 6740 switches can be ordered with fans that move air either front to
back (exhaust) or back to front (intake), 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.
For the Brocade VDX 6740 - A maximum flow of 43.7 cubic meters/hour (25.7 cubic
feet/minute) at the intake vents.
For the Brocade VDX 6740T and Brocade VDX 6740T-1G - A maximum flow of 83.8 cubic
meters/hour (49.3 cubic feet/minute) at the intake vents.
The ambient air temperature does not exceed 40C (104F) while the switch is operating.

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.
The rack space required is one rack unit (1U) 44.45 mm (1.75 in.) high and 482.60 mm (19
in.) wide.
8 Brocade VDX 6740 Hardware Reference Manual
53_1002829_02
Installation and safety considerations
NOTE
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.
Ensure that the rack mounting does not impede airflow or negatively affect temperature
requirements, particularly if the switch is installed in a closed or multirack assembly. The Brocade VDX 6740T and Brocade VDX 6740T-1G have airflow openings on either side of the switch toward the front. Ensure that these openings are not obstructed.
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 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 cabinet or patch panels to reduce the potential for tangling the cables. The following list provides some recommendations for cable management:
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 the 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 VDX 6740 switches for use in a network and fabric:
A workstation with an installed terminal emulator, such as HyperTerminal.
An unused IP address and corresponding subnet mask and gateway address.
A serial cable (provided).
An Ethernet cable.
(Optional) Access to an FTP server or Brocade-branded USB device for backing up the switch
configuration.
If mounting in the iDataplex IBM 15.5-inch depth rack, the Brocade iDataplex rack mount kit.
