Overview of Brocade 7840 Extension Switch
The Brocade 7840 Extension Switch is intended as a platform for Fibre Channel over IP (FCIP). This
enables transmission of Fibre Channel data over long distances by way of IP networks by wrapping
Fibre Channel frames in IP packets. Each end of the FCIP communication path must be a compatible
FCIP device.
The switch can operate independently or in a fabric containing multiple extension switches.
Brocade 7840 software features
The Brocade 7840 provides the following software features:
• Multiple logical FCIP tunnels with maximum tunnel bandwidth up to 20Gbps allow for scalable
connectivity between sites. Note that the 7840 does not support FCIP connectivity with any other
products including the Brocade 7800 and FX8-24.
• FCIP Trunking feature allows multiple IP source and destination address pairs (defined as FCIP
circuits) via multiple 1/10GbE or 40GbE interfaces to provide high bandwidth FCIP tunnel and
lossless failover resiliency. In addition, each FCIP circuit supports four QoS classes (Class-F, High,
Medium and Low Priority), each as a TCP connection.
• ARL feature meets minimum bandwidth guarantee for each tunnel while making the full utilization of
the available network bandwidth without adverse throughput performance impact at high traffic load.
• Hardware-based compression delivers the ability to maximize throughput over lower bandwidth links
in the wide area network, optimizing the cost efficiencies of FCIP. The 7840 compresses FC frames
before they are encapsulated into FCIP packets.
• Key protocol features are enabled in the FCIP implementation to optimize performance of Extension
over IP networks, including FX8-24 and WAN Optimized TCP (WO-TCP), 9K jumbo frame and end-
to-end Path MTU auto discovery.
• Hardware-based IPsec supports mix of secure and non-secure tunnels on the same Ethernet port,
jumbo frames, and VLAN tagged connections. The Brocade 7840 IPsec function is capable of
supporting both IPv4 and IPv6.
• FastWrite, Open Systems Tape Pipelining and Advanced Accelerator for FICON mitigate the latency
effect of a long distance FCIP distance connection over IP WAN.
• FCIP HCL (Hot Code Load) provides In-service firmware upgrade for supporting 24/7 non-stop
business operations
• Built-in WAN link tester generates traffic over an IP connection to test for maximum throughput,
congestion, loss percentage, out of order deliver, latency, and other network conditions. It helps
determine the health of a WAN link before deploying it for use.
• Fabric Vision advanced monitoring provides the following functions:
Brocade 7840 Extension Switch Hardware Reference Manual 11
53-1003127-02

‐Policy based monitoring monitors FCIP connectivity and WAN anomalies using multi-layer
metrics.
‐Flow monitoring reports IOPS and data rate of individual I/O flows of inter-DC replication
and tape backup operations.
‐Flow generator generates FC frames for a defined flow with default or custom size and
pattern and sent across FCIP tunnel to help validate end to end network setup and
configuration.
• Brocade Fabric OS delivers distributed intelligence throughout the network and enables a wide
range of value-added applications.
Brocade 7840 hardware features
The Brocade 7840 provides the following hardware features:
• 24 Fibre Channel ports with link speeds of 2, 4, 8, and 16 Gbps, compatible with short wavelength
(SWL), long wavelength (LWL) and extended long wavelength (ELWL) SFP+ transceivers
• Rack-mountable 2U chassis
• Sixteen 1 GbE/10 GbE ports, compatible with copper, ultra short reach (USR), short reach (SR) and
long reach (LR) SFP/SFP+ transceivers
• Two 40 GbE ports, compatible with short reach (SR) and long reach (LR) QSFP transceivers
• One RJ-45 Ethernet management port with 10/100/1000 Mbps autonegotiating capability
• One USB port that provides storage for firmware updates, output of the supportSave command,
and storage for configuration uploads and downloads
• Two redundant, hot-swappable 1100 W AC/DC power supply units (PSUs) with integral fans
• 3 port-side exhaust DC fan FRUs
NOTE
QSFPs used in the FC16-64 blades (and 8510 core blades) are not compatible with the Brocade 7840.
Brocade 7840 feature licensing
The Brocade 7840 provides the following licensing features:
• Tiered WAN throughput licensing provides coverage of multiple customer segments with one
physical platform:
NOTE
The application throughput numbers shown in the following table assume that some degree of data
compression is occurring. However, Brocade makes no promises, guarantees, or any indication that
some level of compression is possible for customer-specific data. Some data is highly compressible
and some data cannot be compressed. The amount of application throughput varies depending on
data compressibility and the selected compression mode.

Installation and safety considerations
You can install the switch in the following ways:
• As a standalone unit on a flat surface.
• In an EIA rack using the Universal Two-Post Rack Kit or Universal Four-Post Rack Kit.
To install and operate the switch successfully, ensure that the following requirements are met:
• The primary AC input is 100-240 VAC (Brocade 7840 autosenses input voltage), 50-60 Hz. 200-240
VAC is recommended.
• The primary outlet is correctly wired, protected by a circuit breaker, and grounded in accordance with
local electrical codes. It is best practice that each power supply obtain its power from a different
protected and wired source. It is best practice that each power supply obtain its power from a
different protected and wired source.
• The supply circuit, line fusing, and wire size are adequate, as specified by the electrical rating on the
Brocade 7840 nameplate.
For power supply information, refer to Power supplies and fans on page 37.
To ensure adequate cooling, install the Brocade 7840 with the nonport side, which contains the air
intake vents, facing a cool-air aisle.
CAUTION
Make sure the airflow around the front, sides, and back of the device is not restricted.
Verify that the ambient air temperature does not exceed 40°C ( 104°F) and that the ambient humidity
remains between 20 and 85 percent while the Brocade 7840 is operating.
CAUTION
Do not install the device in an environment where the operating ambient temperature might
exceed 40°C (104°F).
If installing the Brocade 7840 in a rack:
• The rack must be a standard EIA rack.
• Plan for a rack space that is 2U ( 8.89 cm; 3.5 in.), (19 in.) 48.3 cm wide, and at least 61cm (24 in.)
deep.
• Ground all equipment in the rack through a reliable branch circuit connection and maintain ground at
all times. Do not rely on a secondary connection to a branch circuit, such as a power strip.
Brocade 7840 Extension Switch Hardware Reference Manual 19
53-1003127-02

• Ensure that airflow and temperature requirements are met on an ongoing basis.
• Verify that the additional weight of the Brocade 7840 does not exceed the rack’s weight limits or
unbalance the rack in any way.
DANGER
Make sure the rack housing the device is adequately secured to prevent it from becoming
unstable or falling over.
Installation Precautions
Review all installation precautions before installing the device.
General precautions
DANGER
The procedures in this manual are for qualified service personnel.
CAUTION
Changes or modifications made to this device that are not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.
DANGER
All fiber-optic interfaces use Class 1 lasers.
Power Precautions
This Extension Switch might have more than one power cord. To reduce the risk of electric shock,
disconnect both power cords before servicing.
DANGER
Remove both power cords before servicing.
DANGER
Disconnect the power cord from all power sources to completely remove power from the
device.
CAUTION
Before plugging a cable into to any port, be sure to discharge the voltage stored on the cable
by touching the electrical contacts to ground surface.
Connect the power cord only to a grounded outlet.
DANGER
Make sure that the power source circuits are properly grounded, then use the power cord
supplied with the device to connect it to the power source.
