See Figure Figure 18 Removing the protection box (1) Loosen the captive screws (2) Pull the ejector levers outward (3) Pull out the LPU...
Page 31 Hold the LPU by the front panel with one hand and support its bottom with the other. Slide the LPU steadily into the target slot along the guide rails. Do not touch the components on the PCB. As shown in callout 1 in Figure 19, push the LPU until the brakes on its ejector levers touch the slot edges tightly.
Page 32: Installing A Switching Fabric Module
Installing a switching fabric module Every 12910 AC switch has six switching fabric module slots numbered 10 through 15. For the proper operation of the switch, at least one switching fabric module must be installed in slot 10, slot 1 1, or slot The gray edged switching fabric module slots of a 12910 AC switch are located at the rear panel.

Figure 25 Installing an SFP+/SFP/QSFP+ module Connecting an SFP+/QSFP+/QSFP+ to SFP+ cable Use SFP+ cables to connect SFP+ ports, QSFP+ cables to connect QSFP+ ports, and QSFP+ to SFP+ cables to connect QSFP+ and SFP+ ports. All these cables are hot swappable. To connect an SFP+, QSFP+, or QSFP+ to SFP+ cable: Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well grounded.
Page 39: Setting Up An Irf Fabric
Setting up an IRF fabric You can use HP IRF technology to connect and virtualize HP FlexFabric 12900 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 12900 Switch Series IRF Configuration Guide.
Page 40: Planning Irf Fabric Setup
Planning IRF fabric size and the installation site Plan IRF fabric size and the installation site, as follows: Use HP FlexFabric 12900 Switch Series IRF Configuration Guide as a reference to identify the number of member switches that your system software version supports for an HP FlexFabric 12900 IRF fabric.
Page 41: Identifying The Master Switch And Planning Irf Member Ids
On HP FlexFabric 12900 switches, only 10-GE/40-GE ports can be used for IRF connection. The HP FlexFabric 12900 switches support multi-card link aggregation for IRF ports. You can bind up to eight physical ports to one IRF port. Installing IRF member switches...

Cut the top of the wires even with one another. Insert the wires into the RJ-45 end and make sure the wires extend to the front of the RJ-45 end and make good contact with the metal contacts in the RJ-45 end and in the correct order.
Page 95: Pigtail Cord
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 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.
Page 96: Sfp+ Cable
Never bend or curve a fiber when connecting it. After a fiber is installed well, the bend radius must • be not less than 40 mm (the minimum dynamic bend radius is 20 D, and the minimum static bend radius is 10 D. D indicates the outer diameter of dust caps). •...

Page 98: Appendix E Engineering Labels
Appendix E Engineering labels Engineering labels are used to identify cables and devices for easy maintenance after installation. There are two types of engineering labels, labels for cables and labels for devices. Labels for cables You can affix labels to network cables (twisted-pair cables and optical fibers) and power cables. Labels for network cables A label for network cables is L-shaped with fixed dimensions.
Page 99: Generic Labels
Figure 62 Label for power cables (1) Cable tie (2) Dividing line on the label Generic labels A generic label is bar-shaped with fixed dimensions. It is applicable to all cables. A mark "TO:" is located at the upper left corner in the right area of the label to identify the peer end of the cable on which the label is affixed.
Page 100: Labels For Devices
A device label is used to identify the device name, model, address, installation date, and so on. Filling in labels You can print or write desired contents on labels. HP recommends that you print labels. To print labels, select a label printer and a proper label template as needed. For more information about using a label printer, see the user guide of the printer.

Page 105: Engineering Labels For Optical Fibers
Engineering labels for optical fibers These labels are affixed to optical fibers that connect the fiber ports on the cards in a chassis, or connect fiber ports on box-type devices. There are two types of labels for optical fibers: labels for a fiber that connects the fiber ports on two devices, labels for a fiber that connects the device and the optical distribution frame (ODF).

Engineering labels for AC power cables These labels are affixed to the AC cables that provide power for cabinets and protection grounding cables, including POWER, RTN, and PGND cables. The 220 VAC cables and related PGND and RTN cables are covered with insulating sheath, so the labels only need to contain "AC" and the cabinet number.

Page 109: Appendix F Cabling Recommendations
Appendix F Cabling recommendations When you mount a 12910 AC switch in a 19-inch standard rack, route network cables through the cable management bracket at the upper part of the front panel. Plan cable routing by using the cable routing lines according to your installation environment and bundle the network cables at the tie-wrap tabs, as shown in Figure...
Page 110: General Cabling Requirements
Figure 75 Routing and bundling power cables on the 12910 AC switch General cabling requirements Minimum curvature radius of cables The curvature radius of an attached power cable, communication cable, or ribbon cable should be • at least five times the cable's outer diameter. If the cable is frequently bent, plugged and unplugged, the curvature radius should be at least seven times the cable's outer diameter.
Page 111: Cable Management Guidelines
Cable management guidelines When you route and bundle up cables, follow these guidelines: • Bind and route the cables neatly inside the rack, and make sure they are not kinked or bent. Figure 76 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.
Page 112 When you bend cables, bind them as shown in Figure 78. To avoid excessive stress causing cable • core break, do not tie up the cables in the bending area. Figure 78 Binding cables where they must be bent Route, bind, and attach excess cables for easy, safe maintenance activities and proper operations. •...

Page 114: Appendix G Repackaging The Switch
Appendix G Repackaging the switch This chapter describes how to repackage the switch chassis, power supply, card, power cable bracket, and plastic panel. 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.
