Switch Overview; Switch Hardware Features - HP OfficeConnect 1820 8G Installation And Getting Started Manual

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 supports the IEEE 802.3at
standard and is capable of providing 185 watts of PoE power through ports 1-12.
• The 1820 48G PoE+ 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 switch supports the IEEE 802.3at
standard and is capable of providing 370 watts of PoE power through ports 1-24.
These switches can be directly connected to computers, printers, and servers to provide dedicated bandwidth
to those devices, and you can build a switched network infrastructure by connecting the switch to hubs, other
switches, or routers. In addition, these switches offer network management capabilities.
