  • Page 5: Preparing For Installation

    IMPORTANT: For regulatory identification purposes, the switches are assigned Regulatory Model Numbers (RMNs). The RMNs should not be confused with the marketing name HP 1920, or the product codes. Safety recommendations To avoid any equipment damage or bodily injury, read the following safety recommendations before installation.

  • Page 6: Examining The Installation Site

    The accessories shipped with the switch, including but not limited to power cables, are intended • only for the switch. Please do not use them for other products. Examining the installation site The switches must be used indoors. You can mount your switch in a rack or on a workbench, but make sure: A minimum clearance of 5 cm (1.97 in) is reserved at the air inlet and exhaust vents for ventilation.

    Maximum concentration (mg/m 0.05 0.01 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.

  • Page 8: Installing The Switch

    WARNING! Before installing or moving the switch, remove the power cord. You can install an HP 1920 switch in a 19-inch rack, on a workbench, or on a wall. Mounting the switch in a 19-inch rack by using mounting brackets Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

    Figure 3 Attaching Type-C mounting brackets to the switch Place the switch on a rack shelf in the rack. Push the switch in until the oval holes in the brackets align with the mounting holes in the rack posts. Attach the mounting brackets to the rack posts with screws.

  • Page 11: Mounting The Switch On A Workbench

    Mounting the switch on a wall Only the HP 1920-8G switch can be installed on a wall. The type of screws used to mount the switch on the wall depends on the wall type. This section uses a concrete wall as an example.

  • Page 12

    Figure 9 Hole spacing Insert one wall anchor into each hole until the anchors are flush with the wall surface. Drive one screw into each wall anchor, and tighten the screws just enough to keep it secure in the wall anchor. Leave a minimum clearance of 1.5 mm (0.06 in) between the base of the screw head and the wall anchor so the switch can hang on the screws securely.

  • Page 13: Connecting Cables

    Connecting cables Connecting network cable Use crossover cable or straight through cable to connect a PC or other network devices to the Ethernet port of the switch. Figure 12 Connecting network cable Installing the SFP transceiver module and optical fibers CAUTION: Hold the SFP transceiver module by its two sides when you install or remove the module.

  • Page 14: Connecting The Console Cable

    Figure 13 Installing the SFP transceiver module and optical fibers Connecting the console cable To connect a terminal (for example, a PC) to the switch: Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. Connect the DB-9 female connector of the console cable to the serial port of the PC.

  • Page 15: Connecting The Dc Power Cord

    Make sure the DC power cord is shorter than 3 m (9.84 ft). The HP 1920-24G-PoE+ (370W) and HP 1920-48G-PoE+ (370W) support DC RPS power. If only the DC power cord is connected, the switch operates correctly when the DC input voltage is in the range of –47 VDC to –57 VDC.

  • Page 16: Verifying The Installation

    Figure 16 Connecting the DC power cord to the DC power receptacle Verifying the installation After you complete the installation, verify the following items: There is enough space for heat dissipation around the switch. • • The rack or workbench is stable. The grounding cable is securely connected.
