HPE OfficeConnect 1620-24G Switch #JG913A
Entry configurable switches for small business networking,

Features & Benefits:

Management

• 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)
• Secure Web GUI
  Provides a secure, easy-to-use graphical interface for configuring the switch via HTTPS
• SNMPv1, v2c, and v3
  Facilitates management of the switch, as the device can be discovered and monitored from an SNMP management station
• Port mirroring
  Enables traffic on a port to be simultaneously sent to a network analyzer for monitoring
• 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 will fall back to a unique static address determined by the switch’s MAC address
• Network Time Protocol (NTP)
  Synchronizes timekeeping among distributed time servers and clients; 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 a NTP server
• Dual flash images
  Provide independent primary and secondary operating system files for backup while upgrading

Quality of service (QoS)

• 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
• Rate limiting
  Sets per-port ingress enforced maximums and per-port, per-queue minimums

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
• Loopback detection
  If the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid broadcast storms
• Energy Efficient Ethernet
  Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity
• Port power save mode
  Enables a port to operate at the lowest transmission speed or go down during a specific time range on certain days of a week. The port resumes when the effective time period ends
• Cable test
  Performs a check on the status of the cable connected to an Ethernet port on the device. The test determines whether a short circuit or open circuit is present on the cable and the approximate length to the fault in the cable

Performance

• Half- and full-duplex auto-negotiating capability on every port doubles the throughput of every port
• IGMP Snooping, v1, v2, and v3
  Improves network performance through multicast filtering, instead of flooding traffic to all ports

Layer 2 switching

• VLAN support and tagging
  Supports IEEE 802.1Q with 4,096 simultaneous VLAN IDs
• Jumbo frame support
  Supports up to 10 kilobyte frame size to improve the performance of large data transfers

Resiliency and high availability

• Link aggregation
  Groups together multiple ports (up to a maximum of eight ports per trunk) automatically using Link Aggregation Control Protocol (LACP), or manually, to form an ultra-high-bandwidth connection to the network backbone; helps prevent traffic bottlenecks. Note: 8 port model support 4 trunks, 24 port model support 8 trunks, and the 48 port model support 16 trunks.

Warranty and support

• Limited Lifetime Warranty
