Installation Precautions • 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.
Items included with the switch 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.
Installing in an EIA rack Installing in an EIA rack The Brocade 7840 can be installed in an EIA rack using one of the following optionally available rackmount kits. Refer to the documentation that is shipped with the rack-mount kit for installation instructions: • Universal Four-Post Rack Kit Installation Procedure Supporting Brocade 7840 Extension Switch • Universal Two-Post Rack Kit Installation Procedure Supporting the Brocade VDX 6740T and Brocade 7840 Extension Switch.
Providing power to the switch NOTE Do not connect the switch to the network until the IP address is correctly set. Providing power to the switch Perform the following steps to provide power to the switch. 1. Connect the power cords to both power supplies and then to power sources on separate circuits to protect against AC failure. Ensure that the cords have a minimum service loop of 6 in. available and are routed to avoid stress. Connecting a power cord turns the switch on.
Setting the switch IP address If ttyb is already in use, use ttya instead and enter the following string at the prompt: tip /dev/ttya -9600 Setting the switch IP address You can configure the switch with a static IP address, or you can use a Dynamic Host Configuration Protocol (DHCP) server to set the IP address of the switch. DHCP is enabled by default. The switch supports both IPv4 and IPv6.
Creating an Ethernet connection Creating an Ethernet connection Perform the following steps to create an Ethernet connection to the switch. 1. Remove the plug from the Ethernet port. 2. Connect an Ethernet cable to the switch Ethernet port and to the workstation or to an Ethernet network containing the workstation. NOTE At this point, the switch can be accessed remotely, by command line or by Web Tools. Ensure that the switch is not being modified from any other connections during the remaining tasks.
Synchronizing local time with an external source This command has the following operand: "newdate" This operand specifies the new date and time enclosed in double quotation marks. this operand is optional; if omitted, the current date and time is displayed. Date and time are specified as a string in the mmddhhmmyy format. • • • • • mm: Specifies the month. Valid values are 01 to 12. dd: Specifies the date. Valid values are 01 to 31. hh: Specifies the hour. Valid values are 00 to 23.
FCIP and Fibre Channel routing services configuration Setting the time zone needs to be done only once, because the value is stored in nonvolatile memory. For U.S. time zones, use the following table to determine the correct parameter for the tsTimeZone command.
Verifying correct operation and backing up the configuration a) b) Remove the plug from the port to be used. Position a transceiver so that it is oriented correctly and insert it into a port until it is firmly seated and the latching mechanism clicks. For instructions specific to the type of transceiver, refer to the transceiver manufacturer’s documentation. c) NOTE The transceivers are keyed to ensure correct orientation. If a transceiver does not install easily, ensure that it is correctly oriented.

Interpreting POST results Interpreting POST results POST is a system check that is performed each time the switch is powered on, rebooted, or reset, and during which the LEDs flash different colors. Perform the following steps to determine whether POST completed successfully and whether any errors were detected. 1.
Field-replaceable units Field-replaceable units You can replace the power supply and fan assemblies on-site without the use of special tools. The fieldreplaceable units (FRUs) are keyed to ensure correct orientation during installation. Replacement instructions are provided with all FRUs ordered. DANGER Remove both power cords before servicing. DANGER Disconnect the power cord from all power sources to completely remove power from the device. Power supplies and fans The two PSU FRUs are hot-swappable.
Removing and replacing transceivers Removing and replacing transceivers Use the following procedure to remove and replace an SFP+ transceiver. The process for removing and replacing QSFP transceivers is the same. DANGER All fiber-optic interfaces use Class 1 lasers. Time and items required The replacement procedure for one transceiver takes less than five minutes.
Operating the Switch 1. Making sure that the bail (wire handle) on an 8 or 10 Gbps transceiver is in the unlocked or open position, position the optical transceiver so that the key is oriented correctly to the port. Insert the transceiver into the port until it is firmly seated and the latching mechanism clicks. 1 SFP+ bail FIGURE 10 Replacing an 8 Gbps SFP+ optical transceiver The 16 Gbps SFP+ transceivers do not have bails.

Removal and Replacement of Power Supplies and Fans ● Removal and replacement introduction...........................................................................41 ● Power supply removal and replacement......................................................................... 42 ● Fan removal and replacement........................................................................................
Power supply removal and replacement The orange I symbol indicates an intake unit. This unit pulls air in from the nonport side of the switch and exhausts it out the port side. This is also called back-to-front airflow or reverse airflow. This symbol should appear on FRUs with part numbers ending with -R . The chassisShow command indicates "reverse" airflow. If one fan fails, the remaining fans go to high speed to maintain proper cooling until the failed fan is replaced.
Time and items required Time and items required Replacing a power supply in the Brocade 7840 switch should require less than two minutes to complete. To replace a power supply in a Brocade 7840, you need a new power supply that has the same part number and airflow indicator as the power supply being replaced. Replacing a power supply Complete the following steps to replace a power supply in a Brocade 7840 switch. 1.
Fan removal and replacement FIGURE 13 Inserting the power supply in the Brocade 7840 6. Verify that the LEDs on the new power supply display steady green while the Brocade 7840 is operating (refer to LEDs on the nonport side of the switch on page 34). If the LEDs are not steady green, ensure that the power supply is securely installed and seated properly. Optionally, if using the command line interface (CLI), enter the psShow command at the command line prompt to display the status.
Determining the need to replace a fan Determining the need to replace a fan Use one of the following methods to determine the status of the fans: • Check the fan status LED (refer to LEDs on the nonport side of the switch on page 34). • In Web Tools, click the Fan Status icon. • Enter the fanShow command at the prompt to display fan status. The output of this command shows the status of five fans. Fans 1, 2, and 3 are the FRU fans. NOTE Fans 4 and 5 are the integral fans of the power supplies.
Removal and Replacement of Power Supplies and Fans c) d) NOTE If you observe that the switch has powered down after two minutes after a fan replacement, it is likely because the new fan has a mismatched airflow. Gently push the fan into the chassis until it is firmly seated. Using the Phillips screwdriver, secure the fan to the chassis by tightening the captive screw. FIGURE 14 Inserting the fan in the Brocade 7840 4.
