HP 1810-24 Switch P/N:J9801A


Manage your network directly from the Web with the ۱۸۱۰ ۲۴ Port Layer 2 Switch from HP. This layer 2 switch comes equipped with 22 autosensing Fast Ethernet ports, 2 autosensing Gigabit Ethernet ports, and 2 100/1000 small form-factor ports. With 128 MB of RAM and 8 MB of Flash memory inside, the switch is capable of handling a high traffic load making it a valuable addition to nearly any small business IT infrastructure. You can even mount this switch into an existing rack as it comes compatible with 1U rackmount configurations


Auto-MDI/MDIX automatically adjusts for straight-through or crossover cables on all ports
Packet storm protection protects against broadcast, multicast, or unicast storms with user-defined thresholds
SFP ports for fiber connectivity provides fiber connections for uplinks and other connections across longer distances than copper cabling can support; true SFP ports operate in addition to available copper Ethernet ports, providing a higher total number of available ports vs. combo ports, which are either a copper or fiber connection


Half- or full-duplex auto-negotiating capability on every port doubles the throughput of every port
Link aggregation (trunking) brings together groups of ports automatically using Link Aggregation Control Protocol (LACP) or, manually, to form an ultra-high-bandwidth connection to the network backbone; helps prevent traffic bottlenecks; this 24-port models has eight trunks of four links each

Quality of Service (QoS)

Traffic prioritization (IEEE 802.1p) allows real-time traffic classification with eight priority levels mapped to four queues
IEEE 802.1p prioritization with DSCP delivers data from the switch to devices based on the priority and type of traffic using Differentiated Services Code Point (DSCP)
Broadcast control allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic

Layer 2 Switching

VLAN support and tagging supports up to 64 port-based VLANs and dynamic configuration of IEEE 802.1Q VLAN tagging, providing security between workgroups
Jumbo packet support improves the performance of large data transfers; supports frame size of up to 9,220 bytes

Resiliency and High Availability

IEEE 802.1D Spanning Tree Protocol (STP) and IEEE 802.1W Rapid Spanning Tree Protocol (RSTP) provide redundant links while preventing network loops


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 six types of 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

Ease of Use

Locator LED (switch) allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; this simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches
Comprehensive LED display with per-port indicators provides an at-a-glance view of status, activity, speed, and full-duplex operation


Flexible installation allows mounting on wall, desktop, or under-table
Rack mountable offers a rack-mounting option with included hardware
Kensington lock slot allows switches to be physically secured in open-space deployments


Simple Web management allows easy management of devices by nontechnical users with its intuitive Web GUI
Secure Web GUI provides a secure, easy-to-use graphical interface for configuring the module via HTTPS
SNMPv1, v2c enable devices to be discovered and monitored from an SNMP management station
Dual flash images provide independent primary and secondary operating system files for backup while upgrading
Port mirroring enables traffic on a port to be simultaneously sent to a network analyzer for monitoring
IEEE 802.1AB Link Layer Discovery Protocol (LLDP) advertises and receives management information from adjacent devices on a network, facilitating easy mapping by network management applications

Additional Features

Energy savings utilizes Energy Efficient Ethernet (EEE) IEEE 802.3az standard for lower power consumption
Green IT and power places inactive ports automatically in low-power mode and its LED in power-down mode, to conserve energy
Green initiative support provides support for RoHS and WEEE regulations
