10/100/1000BASE-T RJ-45 ports Reset button Network Ports • Auto-sensing 10/100/1000BASE-T ports. All these ports have the “Auto-MDIX” feature, which means that you can use either straight-through or crossover twisted-pair cables to connect any network devices to the switch. • Power-over-Ethernet or PoE ports. The 1820 PoE+ switches support the IEEE 802.3at standard, which allows IP telephones, wireless LAN Access Points, and other appliances to receive power as well as data over existing LAN cabling.
State Meaning Power (green) The switch is receiving power. Blinking* (1820 8G only) Power is available on the PoE In port (Port 1). The switch is NOT receiving power. Fault/Locator On briefly after the switch is powered on or reset, at the beginning of (orange) switch self test.
Mode Button The 1820 PoE+ switches have one Mode LED per port. The Mode LED shows either the port speed or the PoE status. In PoE mode, it shows whether the port is configured to provide PoE power. The operation of the Mode LED is controlled by the Mode select button.
◦ Web browser interface — an easy to use built-in graphical interface that can be accessed from common Web browsers. ◦ Intelligent Management Center (iMC) — allows network administrators to discover and map the switches within their network and launch the built-in graphical interface from within iMC to configure the switches.
Installing the Switch The 1820 Switches are easy to install. They come with an accessory kit that includes the brackets for mounting the switches in a standard 19-inch telco rack, in an equipment cabinet, and with rubber feet that can be attached so the switches can be securely located on a horizontal surface.

• The Power LED remains on. • The Fault/Locator LED stays off. • The port LEDs on the front of the switch go into their normal operational mode: ◦ If the ports are connected to active network devices, the Link/Act LEDs stay on or may be blinking to indicate port activity.
NOTE: The mounting brackets have multiple mounting holes and can be rotated allowing for a wide variety of mounting options. These include mounting the switch so its front face is flush with the face of the rack, as shown in the illustration. 2.
To mount the 1820 8-port switches, follow these steps: 1. In the required location, mark the position for the mounting screws. The hole-to-hole distance is 3.54 inch (90 mm). 2. Use a #1 Phillips (cross-head) screwdriver and two of the included 20-mm M4 tap screws. Set the screw heads approximately 2 mm away from the mounting surface to allow the switch to slide onto the screws.
Using a Kensington security cable To prevent unauthorized removal of the switch, you can use a Kensington Slim MicroSaver security cable (not included) to attach the switch to an immovable object. 4. Connect the Switch to a Power Source Procedure 1.
2. Re-check the LEDs during self test. See 2 on page 17. 3. For the 1820 8-port switches, use the included cable tie to secure the power cord to the switch. 5. Connect the Network Cables Connect the network cables, from the network devices or your patch panels, to the fixed RJ-45 ports on the switch or to any SFP transceivers you have installed in the switch.
NOTE: Ensure the network cable is NOT connected when you install or remove an SFP. Installing the SFPs: Remove the protective plastic cover and retain it for later use. Hold the SFP by its sides and gently insert it into any of the slots on the switch until the SFP clicks into place. WARNING: The HPE SFPs are Class 1 laser devices.
Configuring the Switch Initial Configuration The 1820 Switch Series can be managed through a Web-browser interface that you can access from any PC or workstation connected to the switch. To access the Web interface, you must have the switch’s Internet Protocol (IP) address. In the factory default configuration, the IP address is automatically acquired from a Dynamic Host Configuration Protocol (DHCP) service that is available on your network or from your Internet Service Provider (ISP).
See the HPE OfficeConnect 1820 Switch Series Management and Configuration Guide for more switch configuration information. NOTE: If you cannot remember the switch’s IP address or password, you can restore the factory default settings by following the procedure described in Troubleshooting on page 27. Using the 192.168.1.1 IP address If the switch does not acquire an IP address via the DHCP request, it defaults to the following configuration: Parameter...

AC voltage Maximum current Frequency range 1820 48G PoE+ 100-127 volts200-240 5 A / 2.5 A 50/60 Hz (J9984A) volts Requires a connection to an external power adapter. The adapter automatically adjusts to any voltage between 100 and 240 volts and either 50 or 60 Hz. The switch automatically adjusts to any voltage between 100-127 or 200-240 volts and either 50 or 60 Hz.
Because of the increased speed provided by 1000BASE-T (Gigabit-T), network cable quality is more important than for either 10BASE-T or 100BASE-TX. Cabling plants being used to carry 1000BASE-T networking must comply with the IEEE 802.3ab standards. In particular, the cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT).
Installing the Patch Cord As shown in the illustration below, connect the patch cord to the transceiver with the section of single mode fiber plugged in to the Tx (transmit) port. Then, connect the other end of the patch cord to your network cabling patch panel, or directly to the network multimode fiber.
NOTE: Using Fixed Configurations. If the port configuration is changed to any of the fixed configurations though, for example 100 Mbps/full duplex, the port operates as MDI-X only and the correct cable type must be used: for connections to MDI ports, such as end nodes, use a straight-through cable; for connections to MDI-X ports, such as on hubs and other switches, use a crossover cable.
