Product overview

The HPE OiceConnect 1920S Switch
Series consists of advanced smart-managed
fixed-configuration Gigabit switches designed
for small businesses in an easy-to-administer
solution.

The series consists of seven switches
including 8- 24- and 48-port Gigabit
Ethernet switches and 8-, 24- and 48-port
PoE+ models of which half the ports are
POE+ capable. An additional 24-port PoE+
model is available that provides PoE+ on
all 24-ports. All ports provide non-blocking
Gigabit performance. Some models include
SFP ports for fiber connectivity and the
8-, 24- and 48-port non PoE+ models
are fanless, making them ideal for oice
deployments. All HPE OiceConnect 1920S
Switches support flexible installation options,
including mounting on wall, under table, or
on desktop. The 8-port Gigabit Ethernet
model can be powered by an upstream
Power over Ethernet switch for environments
where no line power is available.

The series is part of the OiceConnect
portfolio of Hewlett Packard Enterprise small
business networking products. These switches
provide a great value, and includes features
to satisfy even the most advanced small
business networks. Customizable features
include basic Layer 2 features like VLANs and
link aggregation, as well as advanced features
such as Layer 3 static routing, IPv4 and
IPv6 Host mode, ACLs, and Spanning Tree
Protocols. HPE OiceConnect 1920S Switch
Series includes a Limited Lifetime Warranty.

Simple Web management

Allows for easy management of the switch—
even by nontechnical users—through an
intuitive Web GUI; supports HTTP and HTTP
Secure (HTTPS).

SNMPv1, v2c, and v3

Facilitate management of the switch, as the
device can be discovered and monitored from
an SNMP management station.

Complete session logging

Provides detailed information for problem
identification and resolution.

Port mirroring

Enables traic on a port or VLAN to be
simultaneously sent to a network analyzer
for monitoring.

Dual flash images

Provide independent primary and secondary
operating system files for backup while
upgrading.

Network Time Protocol (NTP)

Synchronizes timekeeping among distributed
time servers; keeps timekeeping consistent
among all clock-dependent devices within
the network so that the devices can provide
diverse applications based on the consistent
time.

Manual network time configuration

Manually set the date and time on the switch
in the absence of an NTP server.

Default DHCP client mode

Allows the switch to be directly connected to
a network, enabling plug-and-play operation;
in absence of a DHCP server on the network,
the switch falls back to the static address
19216811

FTP and TFTP

Provides dierent mechanisms for
configuration updates; FTP allows
bidirectional transfers over a TCP/IP network;
trivial FTP (TFTP) is a simpler method using
user Datagram Protocol (UDP).

Remote monitoring (RMON)

Remote monitoring (RMON) provides
advanced monitoring and reporting
capabilities for statistics, history, alarms
and events. RMON data is retrieved from
the switch through a network management
platform over SNMP.

Quality of service (QoS)

Traic prioritization

Provides time-sensitive packets (like VoIP and
video) with priority over other traic based on
DSCP or IEEE 8021p classification.

IEEE 802.1p/Q VLAN tagging

Delivers data to devices based on the priority
and type of traic; supports IEEE 8021Q.

Class of Service (CoS)

Sets the IEEE 8021p priority tag based on
IP address, IP Type of Service (ToS), Layer 3
protocol, TCP/UDP port number or source
port.

Powerful QoS feature

Supports the following congestion actions:
strict priority queuing (SP) or weighted round
robin (WRR) queuing. SP and WRR queuing
can be configured on individual switch ports.

Connectivity

IPv6 host

Enables switches to be managed and
deployed at the IPv6 network’s edge.

IEEE 802.3X Flow Control

Provides a flow throttling mechanism
propagated through the network to prevent
packet loss at a congested node.

IEEE 802.3at Power over Ethernet (PoE+)

Provides up to 30 W per port, which allows
support of the latest PoE+ capable devices
such as Video IP phones, wireless access
points, and advanced pan/tilt/zoom security
cameras, as well as any 154 W IEEE
8023af-compliant end device; mitigates
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 are PoE/PoE+ capable on the HPE
OiceConnect 1920S 8G PPoE+ 65W switch;
ports 1–12 are PoE/PoE+ capable on the
HPE OiceConnect 1920S 24G 2SFP PPoE+
185W switch; all ports provide PoE/PoE+ on
the HPE OiceConnect 1920S 24G 2SFP
PoE+ 370W switch; ports 1–24 are PoE/PoE+
capable on the HPE OiceConnect 1920S
48G 4SFP PPoE+ 370W switch.

PoE shut down mode

A PoE scheduler provides the ability to define
the hours of PoE power being supplied to 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.

PoE power allocation

Support multiple methods (automatic, IEEE
8023af class, LLDP-MED, or user-specified)
to allocate PoE power for more eicient
energy savings.

SPF 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. Two SFP ports available on 24
and four SFP ports on 48 port models.

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.

Auto MDI/MDI-X

Adjusts automatically for straight-through or
crossover cables on all 10/100/1000 ports.

Energy Eicient Ethernet (EEE)

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.

Advanced classifier based QoS

Classifies traic using multiple match criteria
based on Layer 2, 3, and 4 information.

Packet storm protection

Protects against unknown unicast, broadcast
and multicast storms with user-defined
thresholds.

Rate limiting

Sets per-port ingress enforced maximum or
percent minimum bandwidth per queue.

Auto-PoE power configuration

The switch automatically assigns the required
power to a port for a PD device based on Link
Layer Discovery Protocol (LLDP). Optionally,
the switch permits manual, per port, PoE
power configuration.

Energy savings status

The switch provides an estimated cumulative
energy savings due to green Ethernet
features being enabled.

Energy-eicient cooling

Includes variable speed fans operating only
at the speed necessary to maintain operating
temperature to reduce excess noise and
power consumption by the switch.

Security

Access Control Lists (ACLs)

Enables network traic filtering by creating
an ACL, add rules and match criteria to an
ACL, and apply the ACL to permit or deny
on one or more interfaces or a VLAN. Up to
50 inbound entries may be configured based
on IPv4 source and destination IP and MAC
address, Layer 4 ports and protocol type of
the IPv4 packet.

RADIUS

The switch support RADIUS authentication
and configuration of up to 8 RADIUS servers.

RADIUS Accounting

A robust set of attributes and statistics are
available for collecting information from
the switch.

IEEE 802.1X access control

Authentication of network users on a per port
basis prior to permitting network access. Port
VLAN includes RADIUS VLAN assignment,
dynamic VLAN creation, guest VLAN or into
an unauthenticated VLAN.

Switch 802.1X supplicant

Enables the switch to authenticate itself to a
RADIUS server.

Port isolation

Ports in a port isolation group are restricted
from forwarding Layer 2 traic between
ports in that group; provides data privacy and
security.

Automatic denial-of-service protection

Monitors for malicious attacks and protects
the network by blocking the attacks.

Management password

Provides security so that only authorized
access to the Web browser interface is
allowed.

Secure Sockets Layer (SSL)

Encrypts all HTTP traic, secure access to the
browser-based management of the switch.

Performance

Half-and full-duplex auto-negotiating
capability on every port doubles the
throughput of every port.

Selectable queue configurations

Allows for increased performance by selecting
the number of queues and associated
memory buering that best meet the
requirements of the network applications.

IGMP snooping

Improves network performance through
multicast filtering, instead of flooding traic
on all ports.

SFP fiber uplinks

Provides greater distance connectivity using
Gigabit fiber uplinks.

Layer 2 switching

Spanning Tree Protocol (STP)

Supports standard IEEE 8021D STP, IEEE
8021w Rapid Spanning Tree Protocol (RSTP)
for faster convergence, and IEEE 8021s
Multiple Spanning Tree Protocol (MSTP).

BPDU filtering

Drops BPDU packets when STP is enabled
globally but disabled on a specific port

Jumbo frame support

Supports up to 9216 bytes frame size to
improve the performance of large data
transfers.

VLAN support and tagging

Support for IEEE 8021Q; 256 VLANs with a
VLAN ID range of 2-4093.

Layer 3 services

Address Resolution Protocol (ARP)

Displays the MAC address of another IP host
in the same subnet; supports static ARPs;
proxy ARP allows normal ARP operation
between subnets or when subnets are
separated by a Layer 2 network.

DHCP Relay

Simplifies management of DHCP addresses in
networks with multiple subnets.

Layer 3 routing

Static IPv4 routing

Provides basic routing supporting up to
32 static routes to allow manual routing
configuration.

Link aggregation

Groups together multiple ports up to a
maximum of eight ports per trunk either
automatically using Link Aggregation Control
Protocol (LACP), or manually, to form an
ultra-high-bandwidth connection to the
network backbone; help prevent traic
bottlenecks. The 8 port models support
4 trunks, 16 and 24 port models support
8 trunks, 48 port models support 16 trunks.

Convergence

LLDP-MED (Media Endpoint Discovery)

Defines a standard extension of LLDP that
stores values for parameters such as QoS and
VLAN to configure network devices such as
IP phones automatically.

Auto-voice VLAN

Recognizes IP phones and automatically
assigns voice traic to dedicated VLAN for
IP phones.
