Switch Overview
The HP 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 HP 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 HP 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 HP 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 HP 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.
