Switch (Layer 2) – 4 porty 10/100Base-TX (1. port – předání napájení PoE power-forwarding) a 1 průchozí port (telefon, …). Umisťuje se do standardních evropských krabic (vzdálenost šroubků 60 mm). Bez managementu (správa zařízení – SNMP, Telnet), LED indikátory (napájení, aktivita), priority 802.1p. Napájení přes Ethernet dle 802.3af nebo ze zdroje (není součástí - 3CNJPSL). První port prostupný pro napájení dle 802.3af (pro Access Point apod.). Expand LAN Connectivity at the Wall The 3Com® IntelliJack® Switch NJ105 is a four-port, unmanaged Fast Ethernet switch that supports VoIP, 802.1p Packet Prioritization, and 802.3af Power over Ethernet. This "in the wall" switch mounts in BSI- or DIN-standard wall cutouts for a fraction of what it costs to run Category 5 or 5e cabling. For added flexibility, the pass-through port can connect an analog voice or dedicated LAN line. An innovative port-expansion solution, the IntelliJack Switch installs without disturbing wall structures, ceiling spaces, or day-to-day operations. The wall-secured unit is significantly less vulnerable to theft or damage than a freestanding switch or hub. Hospitals, hotels, classrooms, historical buildings, conference rooms, and cubicles are great candidates for an IntelliJack Switch solution. Multiple power options—including standard Power over Ethernet endspan switches and midspan solutions, and a local AC adapter—are sold separately. The NJ105 can also forward Power over Ethernet to another 802.3af-compatible device, such as a 3Com NBX® Phone. * Delivers end-user convenience and flexibility along with network reliability and physical security * Cost-effectively increases ports for desktops, notebooks, printers, fax machines, VoIP telephones, wireless access points, webcams and other devices * Supports QoS-on-Voice with 802.1p Packet Prioritization to give VoIP traffic and other mission-critical tagged packets priority over non-critical data * Improves network reliability in public or high-traffic areas such as classrooms, laboratories, libraries, or kiosks * Power over Ethernet eliminates clutter of local power cables and hardware; reduces power or data disconnections; supports centralized power backup for critical systems such as phones * Supports all IEEE 802.af Power over Ethernet and some nonstandard inline power systems, including several Cisco power switches (see Product Specifications for details) * Supports local power, using the AC adapter; for LANs without Power over Ethernet capabilities * Fits a variety of outlets—using optional mounting accessories—including floor mounts and double-gang boxes; see Product Options page for a complete listing Product Specifications * Color: Cream * Ports: Four RJ-45 Fast Ethernet; one RJ-45 pass-through port * Ethernet Switching: Store-and-forward, full-/half-duplex autonegotiation 10/100Mbps * Power over Ethernet: Supports any IEEE 802.3af-compliant source, including 3Com SuperStack® 3 Switch 4400 PWR (3C17205) and Power over Ethernet Midspan Solutions (3CNJPSE24, 3CNJPSE); supports non-standard Cisco 3000/4000/6000 Series Power Switches and Power Patch Panel * Local power: 3Com Network Jack AC Power Supply (3CNJPSL) required for LANs without Power over Ethernet capabilities * Power forwarding: Port *4 only; receiving device must be 802.3af-compliant, such as a 3Com NBX® Phone modified with the 3Com NBX Phone Power Module (3CNJVOIPMOD-NBX) * Standards: IEEE 802.1D, 802.1p, 802.3, 802.3af, 802.3i, 802.3u; ISO/DIS 8802/3; QoS, VLANs, SNMP v.1, DHCP; DIN- or BSI 4664:1970-standard outlets with screw separation of 60 mm * Safety, Emissions: CE marking, EN60950, EN55022 Class B, EN55024 * Dimensions: 7.5 cm (3.0 in) high, 7.0 cm (2.80 in) width, 2.8 cm (1.12 in) deep * Temperature: 0o to 35o C (32o to 95o F) operating, -30o to 90o C (-22o to 194o F) storage * Humidity (noncondensing): 10% to 90% operating, 5% to 95% storage Package Contents * IntelliJack Switch * Mounting screws * Trim ring * User guide
