■ 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 HP 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
HP Power over Ethernet (PoE/
PoE+) Planning and Implementation Guide , which is on the HP Web site
at www.hp.com/support/manuals .
■ PoE PD port (1820-8G Switch only).
A network connection to the PoE PD port from a PoE PSE device powers
on the switch.
