Setting up an IRF fabric You can use HPE IRF technology to connect and virtualize 12900E 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 HPE 12900E & 12900 Switch Series IRF Configuration Guide.
Step Description Install IRF member switches. "Installing IRF member switches." Power on the switches. Configure basic IRF settings on See HPE 12900E & 12900 Switch Series IRF Configuration Guide. each switch in standalone mode. Connect the physical IRF ports. Connect physical IRF ports on switches. Enable IRF mode.
Planning IRF topology and connections Connect the IRF member switches through IRF ports, the logical interfaces for the connections between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port 2. To use an IRF port, you must bind a minimum of one physical port to it. When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch.
For more information about configuring basic IRF settings, see HPE 12900E & 12900 Switch Series IRF Configuration Guide. Connecting the physical IRF ports Follow these guidelines to connect the 10GE/40GE/100GE ports between the IRF member switches: • Use SFP+ transceiver modules and fibers or SFP+ DAC cables to connect SFP+ ports. SFP+ DAC cables are mainly used for short distance transmission.

Repeat the above steps with the other end of the cable. Use a cable tester to verify the connectivity of the cable. Optical fiber CAUTION: Use the same types of transceiver modules, pigtail cords, patch cords, and fiber cables. If you use single-mode optical fibers, the transceiver modules, pigtail cords, patch cords, and fiber cables must be single-mode.
Pigtail cords fall into single-mode (yellow) and multi-mode (orange), and can also be classified into SC, LC, FC, and so on based on interface type. Fiber connector Fiber connectors are indispensable passive components in an optical fiber communication system. They allow the removable connection between optical channels, which makes the optical system debugging and maintenance more convenient and the transit dispatching of the system more flexible.
SFP+ DAC cable You can use SFP+ DAC cables to connect the SFP+ ports. The SFP+ DAC cables available for the switch series are 10 G SFP+ Cu cables, as shown in Figure Figure 67 SFP+ DAC cable (1) Connector (2) Pull latch QSFP+ DAC cable You can use QSFP+ DAC cables to connect the QSFP+ ports.
Appendix E Engineering labels Engineering labels (labels for cables and labels for devices) are used to identify cables and devices for easy maintenance after installation. Labels for cables You can affix labels to network cables (twisted-pair cables and optical fibers) and power cords (AC and DC power cords).
Figure 72 Label for power cords (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.
Figure 73 Generic label (1) Dividing line on the label (2) Cut dotted line 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. Hewlett Packard Enterprise recommends that you print labels.
Figure 74 Affixing a label Figure 75 shows the affixed labels when the cable is laid vertically and horizontally. Figure 75 Affixed labels 03 12 Affixing a label to a power cord Stick the label to the recessed rectangular area on the identification plate. You can stick the label to either side of the identification plate.
Figure 76 Affixing a label B03 -48V2 Bind cable ties on both ends of a cable. After the bundling, the finished identification plate must be on top of the cable in horizontal cabling, or on the right side of the cable in vertical cabling. Make sure the label is facing out, as shown in Figure Figure 77 Affixed labels...

Content Meaning Example • M—Row number of the rack in the equipment room, in the range of A to Z. • N—Column number of the rack in the MN—Row number and column equipment room, in the range of 01 to 99. number of ODF For example, G01 is the ODF of Row G and Column 01.
Table 75 Information on labels affixed to AC power cords Content Meaning MN: Rack number (row number and column number in the equipment room) or the location of the socket where the power is led in. The location of the socket is marked according to onsite situation. If the sockets can be MN-AC identified by row number and column number, they can be numbered following the same rule for the rack number.
Make sure labels are affixed in the correct direction. After the cable ties are bundled onto the cable, the identification plates with the labels must face up, and the text on the labels in the same cabinet must be in the same direction, as shown in Figure Figure 83 Example of labels on a DC power cord •...
Appendix F Cabling recommendations Routing network cables The cable management brackets are installed on the two sides of the LPU section. Hewlett Packard Enterprise recommends that you route network cables from the left and right sides of the switch, as shown in Figure Figure 85 Routing network cables (12916E switch)
Routing power cords When you route power cords, take consideration of the layout of the equipment room, including the locations of the power distribution cabinet, AC power receptacles, and lightning protection box. Place all re-connecting facilities, such as receptacles, at the rack bottom (Do not place them at a location out of the rack and easy to reach.) The power supplies of the switch are located at the two sides of the rear panel.
Minimum curvature radius of fibers • When the fiber is wrapped up around the cabling plate, the diameter of the cabling plate should be a minimum of 25 times the fiber's diameter. • When the fiber is being moved, the curvature radius of the fiber should be a minimum of 20 times the fiber's diameter.
