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.
Using HPE SFPs, these products support optional network connectivity with the following speeds and
technologies:
