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. Press the Mode button in to select the PoE mode, or leave
the button in its out position for Spd (speed) mode.
Reset button
The Reset button is used to restore Factory Default settings, or reset the switch while it is powered on.
• Resetting the Switch — Press and release the button. This action clears any temporary error conditions
that may have occurred and executes the switch self test.
• Restoring Factory Default Configuration — Press and hold down for over 5 seconds, the switch will
then complete its self test and begin operating with its configuration restored to the factory default settings.
Any configuration changes you may have made through the web browser interface are removed.
Power Connector
The 1820 24G, 1820 24G PoE+, 1820 48G, and 1820 48G PoE+ Switches do not have a power switch, they
are powered on when connected to an active AC power source. The switches automatically adjust to any
voltage between 100-127 and 200-240 volts and either 50 or 60 Hz. There are no voltage range settings
required.
The 1820 8G and 1820 8G PoE+ Switches do not have a power switch, they are powered on when the
external AC/DC power adapter is connected to the switch and to a power source. The external AC/DC power
adapter supplies 12 volts DC to the switch and automatically adjusts to any AC voltage between 100-240
volts and either 50 or 60 Hz. No voltage range settings are required.
The 1820 8G Switch can also be powered on by a PoE PD connection to Port 1.
Switch Features
The features of the 1820 Switches include:
• 8, 24, or 48 auto-sensing 10/100/1000BASE-T RJ-45 ports.
• 2 or 4 SFP slots for HPE SFP transceivers (1820 24G, 1820 24G-PoE+, 1820 48G, and 1820 48G-PoE+
Switches only)
• plug-and-play networking—all ports are enabled—just connect the network cables to active network
devices and your switched network is operational.
• IEEE 802.3ab Auto MDI /MDI-X on all twisted-pair ports, meaning that all connections can be made using
straight-through twisted-pair cables. Cross-over cables are not required, although they will also work. The
pin operation of each port is automatically adjusted for the attached device: if the switch detects that a
10/100/1000 Mbps switch or hub is connected to the port, it configures the port as MDI; if the switch
detects that a 10/100/1000 Mbps end-node device is connected to the port, it configures the port as MDIX.
• all switches support IEEE 802.3az Energy Efficient Ethernet (EEE) features that reduce power
consumption when connected with EEE-compliant client devices.
• automatic learning of MAC addresses in each switch’s 8K-address (8- and 24-port switches) or 16Kaddress (48-port switches) forwarding table.
• automatically negotiated full-duplex operation for all 10/100/1000BASE-T RJ-45 ports when connected to
other auto-negotiating devices
• easy management of the switch through several available interfaces:
10 Mode 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.
• support for up to 64 IEEE 802.1Q-compliant VLANs so you can divide the attached end nodes into logical
groupings that fit your business needs.
• support for up to 16 trunks (48-port switches) so you can assign physical links to one logical link (trunk)
that functions as a single, higher-speed link providing dramatically increased bandwidth.
• support for many advanced features to enhance network performance—for a description, see the
Management and Configuration Guide.
• download of new switch software for product bug fixes.
