HPE OfficeConnect 1820 Switch Series
Overview
Page 3
Delivers data to devices based on the priority and type of traffic; supports IEEE 802.1Q.
Connectivity
• Auto-MDI/MDIX
Automatically adjusts for straight-through or crossover cables on all ports.
• IEEE 802.3X flow control
Provides a flow throttling mechanism propagated through the network to prevent packet loss at a congested node.
• Loop protection
If the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid
broadcast storms.
• SFP ports for fiber connectivity
Provides fiber connections for uplinks and other connections across longer distances than copper cabling can support;
SFP ports are in addition to available copper Ethernet ports, providing a higher total number of available ports. SFP ports
available on 24- and 48 port models.
• IEEE 802.3af PoE-powered device option
Obtains power provided by a standard PoE device connected to Port 1; deploy the switch wherever an Ethernet cable can
reach as a power outlet is not needed (8-port GbE non-PoE+ model only).
• IEEE 802.3at Power over Ethernet (PoE+)
Provides up to 30W per port, which allows support of the latest PoE+-capable devices such as IP phones, wireless access
points, and security cameras, as well as any IEEE 802.3af-compliant end device; lowers the cost of additional electrical
cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments.
• PoE+ port availability
Ports 1-4 provide PoE+ on the HPE 1820-8G-PoE+ (65W) switch. Ports 1 – 12 provide PoE+ on the HPE 1820-24G-PoE+
(180W) switch. Ports 1-24 provide PoE+ on the HPE 1820-48G-PoE+ (370W) switch.
• Auto PoE power configuration
The switch automatically assigns the required power to a port for a PD device based on LLDP (Link Layer Discovery
Protocol). Optionally, the switch permits manual, per port, PoE power configuration.
• PoE shut down mode
A PoE scheduler provides the ability to define the hours of PoE power being supplied on a group of switch ports based on
a 24 hour day. The scheduler enables the flexibility to select individual days of a week as well as reoccurrence on a weekly
basis with a start and end date.
• Energy Efficient Ethernet
Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity.
• Auto port shut-down
The switch saves power by automatically shutting down power to inactive ports. Power is restored on a port upon link
detection.
• Energy savings status
The switch provides an estimated cumulative energy savings due to green Ethernet features enabled.
Security
• Secure Sockets Layer (SSL)
Encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch.
• Automatic denial-of-service protection
Monitors nine types of malicious attacks and protects the network by blocking these attacks.
• Management password
Provides security so that only authorized access to the Web browser interface is allowed.
