Examining the installation site The switch must be used indoors. You can mount your switch in a rack or on a workbench, but make sure: Adequate clearance is reserved at the air inlet and outlet vents for ventilation. The rack or workbench has a good ventilation system.
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in the following ways: A conduction pattern of capacitance coupling. Inductance coupling. Electromagnetic wave radiation. Common impedance (including the grounding system) coupling. To prevent EMI, perform the following tasks: ...
Installing the switch CAUTION: Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to open the chassis, contact your local Hewlett Packard Enterprise agent for permission. Otherwise, Hewlett Packard Enterprise shall not be liable for any consequence caused thereby. Figure 1 Hardware installation flow Start Install the switch to...

WARNING! Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire main or lightning rod. The power interface and grounding terminals in this section are for illustration only. The 5120 24G PoE+ (370W) SI switch comes with a ring terminal for connecting to a grounding strip. For other switch models, you must prepare ring terminals yourself.

Connecting the power cord WARNING! Make sure the grounding cable has been correctly connected before powering on the switch. Table 7 to identify the power cord connection procedures available for your switch. Table 7 Power cord connection methods at a glance Chassis Connection procedure ...
Tighten the screws on the plug with a flat-blade screwdriver to secure the plug in the RPS receptacle (see callout 2 in Figure 19). Connect the other end of the power cord to the RPS. Make sure the RPS is supplying power and verify that the RPS status LED is ON. Figure 19 Connecting the RPS cable to the –52 to –55 RPS receptacle Verifying the installation After you complete the installation, verify that:...
Accessing the switch for the first time Setting up the configuration environment The first time you access the switch you must use a console cable to connect a console terminal, for example, a PC, to the console port on the switch. Figure 20 Connecting the console port to a terminal Connecting the console cable Console cable...
NOTE: Identify the mark on the console port and make sure you are connecting to the correct port. The serial ports on PCs do not support hot swapping. To connect a PC to an operating switch, first connect the PC end. To disconnect a PC from an operating switch, first disconnect the switch end. Setting terminal parameters To configure and manage the switch through the console port, you must run a terminal emulator program, HyperTerminal or PuTTY, on your configuration terminal.
Setting up an IRF fabric You can use Hewlett Packard Enterprise Intelligent Resilient Framework (IRF) technology to connect and virtualize 5120 SI switches into a virtual switch called an "IRF fabric" or "IRF virtual device" for flattened network topology, and high availability, scalability, and manageability. IRF fabric setup flowchart Figure 22 IRF fabric setup flowchart Start...
To set up an IRF fabric: Step Description Plan the installation site and IRF fabric setup parameters: Planning IRF fabric size and the installation site Identifying the master switch and planning IRF member IDs Plan IRF fabric setup ...
Planning IRF topology and connections You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Rather, the IRF fabric changes to a daisy chain topology without interrupting network services.
Identifying physical IRF ports on the member switches Identify the physical IRF ports on the member switches according to your topology and connection scheme. All network ports can be used for IRF connection. As a best practice, use Gigabit SFP ports and HPE 3600 Switch SFP Stacking Kit cables for IRF connection.
Configuring basic IRF settings After you install the IRF member switches, power on the switches, and log in to each IRF member switch (see the fundamentals configuration guide for your switch) to configure their member IDs, member priorities, and IRF port bindings. Follow these guidelines when you configure the neighboring switches: ...
Maintenance and troubleshooting Power supply failure The 5120 SI switches use built-in power supplies. The 5120 24G PoE+ (370W) SI switch support three power input modes: AC input, RPS DC input, and concurrent AC and RPS DC inputs. All other 5120 SI switches support only AC power input.
If the power LED is on but the RPS status LED is off, an RPS input failure has occurred. Verify the following items: The switch is securely connected to the RPS. The RPS is correctly working. NOTE: If the problem persists, contact the Hewlett Packard Enterprise technical support for help. Configuration terminal problems If the configuration environment setup is correct, the configuration terminal displays booting information when the switch is powered on.
