1 Switch Overview
The HPE OfficeConnect 1820 Switch Series are multiport switches that can be used to build
high-performance switched workgroup networks. These switches are store-and-forward devices
that offer low latency for high-speed networking. Three of the switches also support the IEEE
802.3at standard for providing PoE+ power to connected devices.
Throughout this manual, these switches will be referred to as the 1820 8G Switch, 1820 24G
Switch, 1820 48G Switch, 1820 8G PoE+ Switch, 1820 24G PoE+ Switch, and the 1820 48G
PoE+ Switch.
• The 1820 8G Switch has 8 auto-sensing 10/100/1000BASE-T RJ-45 ports. Port 1 is a Power
over Ethernet Powered Device (PoE PD) port. The switch can be powered by a network
connection to port 1 from PoE power sourcing equipment (PSE), such as a PoE switch.
• The 1820 24G Switch has 24 auto-sensing 10/100/1000BASE-T RJ-45 ports and two SFP
slots for supported HPE SFP fiber-optic transceivers (ports 25 and 26).
• The 1820 48G Switch has 48 auto-sensing 10/100/1000BASE-T RJ-45 ports and four SFP
slots for supported HPE SFP fiber-optic transceivers (ports 49 to 52).
• The 1820 8G PoE+ Switch has 8 auto-sensing 10/100/1000BASE-T RJ-45 ports. The switch
supports the IEEE 802.3at standard and is capable of providing 65 watts of PoE power
through ports 1-4.
• The 1820 24G PoE+ Switch has 24 auto-sensing 10/100/1000BASE-T RJ-45 ports and two
SFP slots for supported HPE SFP fiber-optic transceivers (ports 25 and 26). The switch

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. For further information regarding PoE power, see the HPE Power over
Ethernet (PoE/PoE+) Planning and Implementation Guide, which is on the Hewlett Packard
Enterprise Web site at www.hpe.com/support/hpesc.
• PoE PD port (1820 8G Switch only).
A network connection to the PoE PD port from a PoE PSE device powers on the switch.
• SFP slots for fiber or copper uplinks.

Blinking
On briefly after the switch is powered on or reset, at the beginning of switch self
test. If the LED remains on, it indicates a detected hardware failure during the
self test.
A fault has occurred on the switch or one of the switch ports. The Link LED for
the port with the fault will blink simultaneously.
The LED is used to locate a specific switch in an area full of switches. The LED
blinks for 30 minutes when activated through the switch software.
The normal state; indicates that there are no fault conditions on the switch.Off

One of these condition exists:
• no active network cable is connected to the port
• the port is not receiving link beat or sufficient light
• Green Mode has been enabled.
Indicates that there is network activity on the port.
If the Link/Act LED is blinking simultaneously with the Fault/Locator LED, it
indicates a fault on the port. The blinking behavior (1 second on, 1 second off)
is the same as the Fault/Locator LED.

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 MDI-X.
• 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 16K-address (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:
◦
◦ Intelligent Management Center (iMC) — allows network administrators to discover and

from common Web browsers.
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.
