HP IntelliJack Gigabit Switch Series

Product overview

HP IntelliJack Gigabit switches are compact 10/100/1000 switches that can be installed in a standard wall outlet box, quickly converting an existing single-port LAN wall outlet into four switched Gigabit Ethernet ports. These "network jacks" provide a simple solution for adding network ports without running more cabling. Unlike conventional desktop switches, HP IntelliJack devices reside out of the way—literally in-the-wall—and so are more secure from theft and difficult to accidentally disconnect or damage. The innovative HP IntelliJack switches provide four Ethernet ports for local connectivity plus one uplink port. Two additional RJ-45 "pass-through ports" flexibly support a range of additional service and user connectivity options. It can be powered locally or via Power over Ethernet (PoE); certain configurations support output of standard PoE on up to two ports to directly power attached devices such as IP phones or wireless access points.
  • Innovative switch with in-the-wall installation
  • Easy, secure port expansion without new cabling
  • PoE powered with PoE forwarding
  • Available Web-managed and unmanaged models
  • 3-year warranty

Quality of Service (QoS)

  • IEEE 802.1p prioritization — delivers data to devices based on the priority and type of traffic


  • Auto-MDIX — automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports
  • Jumbo packet support — supports up to 9216-byte frame size to improve performance of large data transfers


  • Half-/Full-duplex auto-negotiating capability on every port — doubles the throughput of every port

Resiliency and high availability

  • IEEE 802.3ad Link Aggregation Control Protocol (LACP) — aggregate connections for greater overall throughput (managed IntelliJack NJ2000G only)


  • Choice of smart managed and unmanaged models — HP IntelliJack NJ2000G model has an intuitive Web interface for setup of features such as virtual LANs, link aggregation, and 802.1X Network Login; HP IntelliJack NJ1000G is an unmanaged plug-and-play wall-mount switch with no customization capabilities

Layer 2 switching

  • VLAN support and tagging — support up to 64 port-based VLANs and dynamic configuration of IEEE 802.1Q VLAN tagging, providing security between workgroups (managed IntelliJack NJ2000G only)


  • IEEE 802.1X Network Login — control port-based access for authentication and accountability (managed IntelliJack NJ2000G only)

Ease of use

  • Flow control — helps ensure reliable communications during full-duplex operation
  • Comprehensive LED display with per-port indicators — provides an at-a-glance view of status, activity, speed, and full-duplex operation


  • Designed with no fan — enables quiet operation for deployment in open spaces

Warranty and support

  • 3-year warranty — with advance replacement and next-business-day delivery (available in most countries)

Standards and protocols

General protocols
  • IEEE 802.3ab 1000BASE-T
  • IEEE 802.3af Power over Ethernet
  • IEEE 802.3i 10BASE-T
  • IEEE 802.3u 100BASE-X
  • ANSI/TIA/EIA-568

These switches can be powered by standard 802.3af PoE or by local power adapter. Also, they can be powered by certain pre-standard PoE+ implementations including HP V1910 PoE (JE007A) switches which use Layer 1 "two finger" power signaling.

LLDP PoE+ signaling of the 802.3at standard is not supported. When powered locally or by pre-standard PoE+ from select HP switches, the IntelliJack is capable of forwarding standard 802.3af PoE to up to two attached devices.
