IMPORTANT: For regulatory identification purposes, the switches are assigned Regulatory Model Numbers (RMNs). The RMNs should not be confused with the marketing name HP 1420, or the product codes. Safety recommendations To avoid any equipment damage or bodily injury, read the following safety recommendations before installation.
Examining the installation site The switches must be used indoors. You can mount your switch in a rack, on a horizontal surface, on a wall, or under a table. Make sure the following requirements are met: • A minimum of 5 cm (1.97 in) of clearance is reserved at the air inlet and outlet vents for ventilation. The rack has a good ventilation system and the air inlet and outlet vents are not blocked when the •...
Maximum concentration (mg/m 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.
WARNING! Before installing or moving the switch, remove the power cord. You can install an HP 1420 switch in a 19-inch rack, on a horizontal surface, on a wall, or under a table. Rack mounting Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

Wall mounting Only the HP 1420- 1 6G 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.

Figure 7 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.
Regularly inspect the installation of the switch to ensure that the switch remains securely anchored and unobstructed. Only the HP 1420- 1 6G switch supports under-table mounting. The wall mounting screws (provided) can be used when you mount the switch under a table.
• • The fiber ports on the HP 1420-24G-2SFP Switch operate in autonegotiation mode. For the link between the switch and the peer device to operate correctly, verify that the fiber ports on the peer device also operate in autonegotiation mode.
Connecting the AC power cord Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. (Optional.) Connect one end of the grounding cable to the grounding screw on the rear panel, and connect the other end to the ground. Make sure the correct power source is used.

Appendix B LEDs Power LED Table 4 Power LED description Status Description Steady green The switch is powered on and the power supply is operating correctly. The switch is powered on and is performing the self-test. The switch is faulty if the LED Flashing green flashes green for five seconds.
NOTE: A port with a smaller port ID has a higher priority for getting power. When the PoE power reaches the guard band and a new port requires power, the switch compares the port IDs and performs one of the following actions: Does not supply power to the new port if the ID of the new port is greater than IDs of all existing ports.
Appendix C Troubleshooting Table 10 describes the troubleshooting methods for common issues that you might encounter while using and managing the switch. If a problem persists, contact HP Support. Table 10 Troubleshooting methods Symptom Troubleshooting method Verify that the correct power source is used and the power cords are correctly connected.
