All these cables are hot swappable. To connect an SFP+, QSFP+, or QSFP+ to SFP+ cable: 1.
Setting up an IRF fabric You can use HP IRF technology to connect and virtualize the switches into a large virtual switch called an "IRF fabric" for flattened network topology, high availability, scalability, and manageability. For more information about IRF, see HP FlexFabric 11900 Switch Series IRF Configuration Guide. IRF fabric setup flowchart The setup flow is shown in Figure 25.
Step Description Plan the installation site and IRF fabric setup parameters: 1. Plan IRF fabric setup. • • • • Planning IRF fabric size and the installation site Identifying the master switch and planning IRF member IDs Planning IRF topology and connections Identifying physical IRF ports on the member switches 2. Install IRF member switches. See "Installing the switch." 3. Power on the switches. N/A 4. Configure basic IRF settings on each switch in standalone mode.
An IRF fabric has only one master switch. You configure and manage all member switches in the IRF fabric at the CLI of the master. IRF member switches will automatically elect a master. You can affect the election result by assigning a high member priority to the intended master switch. For more information about master election, see HP FlexFabric 11900 Switch Series IRF Configuration Guide. Prepare an IRF member ID assignment scheme.
• First configure the member IDs, member priorities, and IRF port bindings for the IRF member switches, save the configuration, connect the member switches, and change the operating mode of the switches to IRF mode. • Assign the master switch higher member priority than any other switch. • Bind physical ports to IRF-port 1 on one switch and to IRF-port 2 on the other switch. • Execute the display irf configuration command to verify the basic IRF settings.
Verifying the IRF fabric configuration After you finish configuring basic IRF settings and connecting IRF ports, verify the basic functionality of the IRF fabric, as follows: 1. Log in to the IRF fabric through the console port of any member switch. 2. Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and the remote network management station can reach each other. 3. Use Telnet or SNMP to access the IRF fabric from the network management station.
Connecting your switch to the network This chapter describes how to connect your switch to a network. The first time you access the switch you must log in through the console port. On the switch, you can configure Telnet or SSH for remote access through Ethernet ports. You manage console login users at AUX user lines, and manage Telnet and SSH users at VTY user lines. For more information about login methods and user lines, see HP FlexFabric 11900 Switch Series Fundamentals Configuration Guide.
Figure 27 Connecting a console port to a terminal Setting terminal parameters To configure and manage the switch, you must run a terminal emulator program on the console terminal. If your PC runs Windows 2003 Server, add the HyperTerminal component before performing the following steps to log in to and manage the switch.

• The system status LEDs on the MPUs show that the system is operating correctly. For more information about LED behaviors, see "Appendix C LEDs." Configuring the switch By default, the switch does not authenticate the console login user at an AUX interface. To increase system security and enable remote management: • Configure remote access services, for example, Telnet or SSH. • Configure authentication on each user interface, including the AUX interfaces.
Configuration example Configuring Telnet service # Enter system view. system-view # Enable the Telnet server. [Sysname] telnet server enable # Enter the view of user line VTY 0. [Sysname] user-interface vty 0 # Enable password authentication on the user line. [Sysname-ui-vty0] authentication-mode password # Set the password to hello in plaintext. [Sysname-ui-vty0] set authentication password simple hello # Assign user role network-admin through the user line VTY 0.
[Sysname-mst-region] quit # Configure the switch as the primary root bridge of instance 1. [Sysname] stp instance 1 root primary # Enable MSTP globally. [Sysname] stp global enable For more information about these features, see HP FlexFabric 11900 Switch Series Configuration Guides. Verifying the network configuration To verify the software version and network configuration, execute display commands in any view. Task Command Display the name, model, and system software version of the switch.
Connecting your switch to the network through optical fibers WARNING! To avoid injury to your eyes, do not stare at the optical fiber interfaces and optical fiber connectors when connecting optical fibers. You can install a transceiver module (see "Installing FRUs") in a fiber port and use optical fibers to connect the port to the network. For more information about optical fibers, see "Appendix D Cables." To connect a fiber port to a peer device through optical fibers: 1.
Testing connectivity After you plug the switch into the network, use the ping or tracert command to test the network connectivity. For more information about these commands, see HP FlexFabric 11900 Switch Series Command References.
Troubleshooting This chapter describes how to troubleshoot your switch. TIP: • Clean your switch periodically because the noncompliant operating environments of switches may cause switch failures. • Verify the installation environments against the requirements in "Preparing for installation." Make sure the switch operates in a compliant environment. • Periodically perform the power-on test for the spare switches.
Garbled terminal display If terminal display is garbled, verify that the following settings are configured for the terminal, for example, HyperTerminal: • Baud rate—9,600 • Data bits—8 • Parity—none • Stop bits—1 • Flow control—none When you modify the settings for the console port of the switch, configure the same settings for the console terminal.
7. Plug a new power supply of the same model into the same slot, and connect it to the same power input end. If the new power supply can operate correctly, the old power supply has failed. You must replace the old power supply. Fan failure Both the MPU and the fan tray provide the fan tray LEDs, including an OK LED and a FAIL LED. When the fan tray operates correctly, the OK LED is on, and the FAIL LED is off. If the OK LED is off or the FAIL LED is on, the fan tray has failed.
3. Calculate the total power consumption, and make sure your power supplies can provide enough power. For more information, see "Appendix B FRUs and compatibility matrixes." 4. Verify that the card is fully seated. You can unplug the card, plug it again, and press the ejector levers inward until the ejector levers touch the panel tightly. For a switching fabric module, you must verify that the ejector levers touch the panel tightly and the switching fabric module seats into the backplane. 5.
Replacement procedures CAUTION: When replacing FRUs while the switch is running, be aware of electrical safety hazards. The switch uses a modular, hot-swappable architecture, and supports FRUs. You can replace any of FRUs when the switch is running. Replacing a power supply WARNING! • Follow the procedures shown in Figure 35 and Figure 36 to replace a power supply to avoid device or bodily injury.
6. Holding the power supply handle with one hand and, supporting the bottom of the power supply with the other, gently pull the power supply out, as shown in callout 2 on Figure 37. 7.

Appendix D Cables This chapter describes cables used for connecting network ports. Table 46 Cable description Cable Port type Application Console cable RJ-45 Ethernet port at one end and DB-9 port at the other end Connects the console port of the switch to the console terminal Ethernet twisted pair cable RJ-45 Ethernet ports Connects RJ-45 Ethernet ports to transmit data. Optical fiber SFP+/SFP/QSFP+ ports Connects the fiber ports to transmit data.
RJ-45 connector An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two ends. Figure 45 shows the pinouts of an RJ-45 connector. Figure 45 RJ-45 connector pinout diagram PIN #8 PIN #1 Cable pinouts EIA/TIA cabling specifications define two standards: 568A and 568B for cable pinouts.
Based on pinouts Ethernet twisted pair cables can be classified into straight through and crossover cables based on their pinouts. • Straight-through—The pinouts at both ends comply with standard 568B, as shown in Figure 46. • Crossover—The pinouts at one end comply with standard 568B, and those at the other end comply with standard 568A, as shown in Figure 47.
Pin assignments Select an Ethernet twisted pair cable according to the RJ-45 Ethernet interface type on your device. An RJ-45 Ethernet interface can be MDI (for routers and PCs) or MDIX (for switches). For the pinouts of RJ-45 Ethernet interfaces, see Table 48 and Table 49.
1. Cut the cable to length with the crimping pliers. 2. Strip off an appropriate length of the cable sheath. The length is typically that of the RJ-45 connector. 3. Untwist the pairs so that they can lay flat, and arrange the colored wires based on the wiring specifications. 4. Cut the top of the wires even with one another.
Patch cords are classified into SC, LC, FC, and so on based on interface type. The length of a patch cord can be 0.5 m (1.64 ft), 1 m (3.28 ft), 2 m (6.56 ft), 3 m (9.84 ft), 5 m (16.40 ft), 10 m (32.81 ft), and so on. Pigtail cord A pigtail cord is an optical fiber that has an optical connector on one end and a length of exposed fiber on the other. The end of the pigtail is fusion spliced to a fiber, connecting the fiber cable and transceiver.
• If the fiber has to pass through a metallic board hole, the hole must have a sleek and fully filleted surface (the filleting radius must be not less than 2 mm). When passing through a metallic board hole or bending along the acute side of mechanical parts, the fiber must wear jackets or cushions. • Insert and remove a plug with care. Never exert a fierce force to the fiber or plug; otherwise the plug may be damaged or the fiber may be broken. Never pull, press or extrude the fiber fiercely.

Appendix E Cabling recommendations When the switch is mounted in a 19-inch standard rack, the interface cables are routed through the cable management brackets, bound at cabling racks on chassis sides, and then routed up or down to pass through the chassis top or the raised floor, depending on the available equipment room condition.
Figure 53 Correct and incorrect cable binding • The cable bend radius at connectors must be at least 5 times the cable diameter, and must be at least twice the cable diameter away from the connectors. • Route different types of cables separately (for example, power cables and signal cables). If they are close to one another, cross them over one another. If you route them in parallel, make sure the space between a power cable bundle and a signal cable bundle is at least 30 mm (1.18 in).
Figure 55 Binding cables where they must be bent • Route, bind, and attach excess cables for easy and safe maintenance and correct operation. • Do not tie power cables to slide rails. • When you connect a cable to an articulated part, such as connecting a grounding cable to a cabinet door, leave enough slack in cables and make sure they are not stressed from any movement of the part. • Cables must be protected at points where they might rub or come in contact with sharp edges or heated areas.
Cable bundle diameter (mm) Space between bundles (mm) 30 200 to 300 • Do not tie cables or bundles in a knot. • The metal parts of the crimped cold-pressed terminal blocks (such as air switch) cannot protrude beyond the blocks.
Appendix F Repackaging the switch This chapter describes how to repackage the switch chassis, power supply, card, mounting bracket, and cable management bracket. Removing cables from the switch Before repackaging the switch, remove all cables such as the power cable, console cable, twisted pair, optical fiber, and grounding cable from the switch. Removing the power cable 1. Prepare the packing bag of the power cable. Make sure the bag is clean, dry, and not damaged. 2.

Put the grounding cable into the accessories box. Removing the twisted pair and optical fiber You must remove twisted pairs and optical fibers from all the interfaces of the switch.
2. Remove all power supplies from the chassis, and then install blank filler panels to the empty slots. For how to remove a power supply and install a blank filler panel, see "Replacement procedures." 3. Put the power supply into the bag. 4. Put the packed power supply and power cable into the box. Place the power supply in a correct direction onto the foam cushion in the box. Otherwise, the power supply cannot be completely seated into the foam cushion. Repackaging the card 1.

Put the chassis onto the pallet base of the wooden carton. Removing cable management brackets and mounting brackets Before repackaging the switch chassis, remove the cable management brackets and mounting brackets from the chassis. Removing the mounting brackets 1. Prepare the packing box of the mounting brackets.
Figure 59 Removing the mounting brackets from the chassis 3. Put the mounting brackets into the box. Removing the cable management brackets The 11908-V has two cable management brackets—the one on the chassis bottom routes power cables, and the one on the chassis top routes other cables. To remove the cable management brackets: 1. Prepare the packing bag of the cable management brackets. Make sure the bag is clean, dry, and not damaged. 2.
Figure 60 Removing the cable management brackets from the 11908-V (1) Loosen the screws that attach the cable management brackets to the chassis. (2) Remove the cable management brackets. Repackaging the switch chassis 1. As shown in Figure 61, align the screw holes on the two sides of the chassis bottom to the L-type brackets on the pallet base of the wooden carton. 2. Screw in the screws shipped with your switch and fasten.
