What is HPE J9981A 1820-48G Managed L2 Gigabit Ethernet Switch? At the lowest price Mi Atlantic Eu
HPE 1820-48G switch:
The HPE Office Connect 1820 switch series plans are basic, logically managed, fixed-configuration Gigabit Ethernet Layer 2 switches designed for small trades looking for key purposes in an easy-to-manage answer. This series is part of the Office Attach portfolio of HPE J9981A 1820-48G minor business chitchatting crops. Some replicas include SFP ports for fiber optic influences, and the 8, 24, and 48-port non-PoE+ models are fanless, making them ideal for office deployment.

All HPE Office Connect 1820 switches provision supple connection
options, with connections on the wall, below the table, or on the desktop. The
8-port Gigabit Ethernet perfect can be powered by an upstream
Power-over-Ethernet (PoE) switch and is appropriate for environs where no line
power is obtainable. These Gigabit adjustments are plug-and-play, and if essential,
you can fine-tune net operations to finish the functions if by a simple GUI
based on a Web browser. Customizable features comprise VLAN, rapid spanning
tree, IGMP prying, link combination relay, and DSCP QoS plan. All models comprise
the latest energy-saving topographies, counting Energy Efficient Ethernet (EEE)
and free port power-off.
Features and benefits management:
Humble web organization allows easy running of the switch
through an instinctive web GUI-even for non-technical users; supports HTTP and
HTTP Secure (HTTPS)
·
SNMPv1, v2c allow detection and nursing of
devices from SNMP organization stations
·
Port reflecting enables the traffic on the port
to be sent to the network analyzer at the same time to monitor dual flash
images. Delivers independent primary and subordinate working system files for
backup during promotions
·
Network Time Procedure (NTP) harmonizes timing
between dispersed time servers and regulars; keeps the judgment of all
clock-dependent devices in the system reliable
·
Manual network time conformation Manually set
the date and time on the difference without an NTP server
·
Evasion DHCP client mode
Quality of Service (QoS)
Traffic Import Bestowing to DSCP or IEEE 802.1p cataloging,
time-sensitive data containers (such as VoIP and video) are as long as before
other traffic; data cartons are mapped to eight hardware lines to obtain a more
efficient amount.
·
Program control allows warning the rate of program
traffic to reduce needless network broadcast traffic
·
IEEE 802.1p/Q conveys data to devices rendering
to priority and traffic type; ropes IEEE 802.1Q
Connectivity
·
Auto-MDI/MDIX Mechanically adjusts
straight-through or cusp chains on all ports
·
IEEE 802.3X flow switch delivers a flow regulating
device spread through the network to prevent pack loss at congested nodes
·
Loop defense If the switch notices a loop, it
will forbid the source port from advancing data packets creating from the
switch to avoid transmission tempests
·
The SFP port used for visual fiber connection
provides visual fiber connection for uplink and other influences, and its
distance is longer than the distance reinforced by copper cable; SFP port is an
addition to the available copper Ethernet port and provides more usability the total number of ports. SFP ports are obtainable for 24 and 48 port models

Obtain the control provided by the standard PoE maneuver
connected to port 1; deploy the switch wherever the Ethernet chain can reach,
because no control outlet is obligatory (only 8-port Gbe non-PoE+ models). Each
port delivers up to 30 W of power to support the latest PoE+ devices, such as
IP phones, wireless access points, and safety cameras, as well as any terminal plans
that comply with the IEEE 802.3af normal; reducing the need for IP phones and
WLAN deployment the cost of extra cables and tours.
PoE+ port availability:
Ports 1–4 deliver PoE+ on HPE Office Connect 1820-8G-PoE+
(65W) modifications; ports 1–12 provide PoE+ on HPE Office Attach 1820-24G-PoE+
(180W) switches; ports 1–24 provide PoE+ on HPE Office Link 1820-48G -PoE+
(370W) PoE+ is if on the switch. The switch automatically allocates the obligatory
power to the ports of the PD device rendering to the Link Layer Discovery
Protocol (LLDP). Otherwise, the switch allows the manual shape of PoE power by the
harbor.
Easy to use:
The radar LED allows the user to set
the sensor LED on a specific difference to be on, broken, or off; simplified
troubleshooting by easily detecting the specific modification in a switch-like
rack. A complete LED display with needles for each port is provided an indication
view of status, activity, speed, and full-duplex process.
