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 (dened 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 trac load.
• Hardware-based compression delivers the ability to maximize throughput over lower bandwidth links in the wide area network,
optimizing the cost eciencies 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 eect of a long distance
FCIP distance connection over IP WAN.
• FCIP HCL (Hot Code Load) provides In-service rmware upgrade for supporting 24/7 non-stop business operations
• Built-in WAN link tester generates trac 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:
– Policy based monitoring monitors FCIP connectivity and WAN anomalies using multi-layer metrics.
– Flow monitoring reports IOPS and data rate of individual I/O ows of inter-DC replication and tape backup operations.
– Flow generator generates FC frames for a dened ow with default or custom size and pattern and sent across FCIP tunnel
to help validate end to end network setup and conguration.
Brocade 7840 Extension Switch Hardware Installation Guide
53-1003127-10 11

• Brocade Fabric OS delivers distributed intelligence throughout the network and enables a wide range of value-added
applications.

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 rmware updates, output of the supportSave command, and storage for conguration
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.
DANGER
Batteries used for RTC/NVRAM backup are not located in operator-access areas. There is a risk of explosion if a battery
is replace by an incorrect type. Dispose of used components containing batteries according to the local ordinance and
regulations.
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-specic 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 device in the following ways:
• As a standalone unit on a at surface.
• In an EIA rack using the Universal Two-Post Rack Kit or Universal Four-Post Rack Kit.
To install and operate the device successfully, ensure that the following requirements are met:
• The primary AC input is 100-240 VAC (the device 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. The
best practice is that each power supply obtains its power from a dierent protected and wired source.
• The supply circuit, line fusing, and wire size are adequate, as specied by the electrical rating on the device nameplate.
For power supply information, refer to Power supplies and fans on page 59.
To ensure adequate cooling, install the device with the nonport side, which contains the air intake vents, facing a cool-air aisle.
CAUTION
Make sure the airow around the front, and back of the device is not
restricted.
Verify that the ambient humidity remains between 20 and 85 percent while the device 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 device 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.) high, 48.3 cm (19 in.) wide, and at least 61 cm (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.
• Ensure that airow and temperature requirements are met on an ongoing basis.
• Verify that the additional weight of the device does not exceed the rack’s weight limits or unbalance the rack in any way.

Use only optical transceivers that are qualied by Brocade Communications Systems LLC and comply with the FDA
Class 1 radiation performance requirements dened in 21 CFR Subchapter I, and with IEC 60825 and EN60825. Optical
products that do not comply with these standards might emit light that is hazardous to the eyes.
Power precautions
This device 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 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.
This product is designed for an IT power system with phase-to-phase voltage of 230V. After operation of the protective device, the
equipment is still under voltage if it is connected to an IT power system.
Recommendations for cable management
Cables can be organized and managed in a variety of ways, such as by using cable channels or patch panels. Note the following
recommendations:
• Plan cable management before installing the device in a rack.
• Leave at least 1 meter (3 feet) 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.

NOTE
A 50-micron cable should not be bent to a radius less than 2 in. under full tensile load and 1.2 in. with no tensile load. Tie
wraps are not recommended for optical cables because they are easily overtightened.
