3Com® IntelliJack® Switch NJ225 FX-SC Product #: 3CNJ225FX-SC Přepínač určený do standardní instalační krabice (60mm) rozšiřující 1-portovou LAN přípojku do 4 Fast Ethernet portů s jedním průchozím portem. Podporuje různé typy napájení včetně standardního IEEE 802.3af napájení po Ethernetu (Power over Ethernet), takže nevyžaduje v místě instalace lokální napájení. Podporuje předání napájení na první port (PoE power-forwarding) a prioritu dat podle 802.1p. Switch (Layer 2) - 4 porty 10/100Base-FX (1. port - předání napájení PoE power-forwarding). Umisťuje se do standardních evropských krabic (vzdálenost šroubků 60 mm). S managementem (správa zařízení - SNMP v1 / RMON (statistika)), LED indikátory (napájení, aktivita), priority 802.1p/TOS/Diffserv tagging i VLANy dle 802.1Q (až 64), 802.1x Network Login, rate limiting (128k - 64Mb/s), port mirroring - RAP (Roving Analysis Port). Napájení přes Ethernet dle 802.3af nebo ze zdroje. První port prostupný pro napájení dle 802.3af (pro Access Point apod.). Expand LAN Connectivity and Manageability at the Wall The 3Com® IntelliJack® Switch NJ225 FX-SC is a four-port, managed Fast Ethernet switch that can support VoIP, IEEE 802.1p Packet Prioritization and IEEE 802.1Q VLANs, and forward IEEE 802.3af Power over Ethernet. This "in the wall" solution mounts in BSI- or DIN-standard wall cutouts, connecting to 100BASE-FX cable with SC connectors, for a fraction of what it costs to run new cabling. The IntelliJack Switch NJ225 FX-SC supports IEEE 802.1X network login for enhanced security. This SNMP-compatible switch includes capabilities for port-, unit-, and group-level administration. It's also enterprise-ready, supporting most management platforms such as 3Com Network Supervisor and HP OpenView. 3Com IntelliJacks are significantly less vulnerable to theft or damage than freestanding alternatives. They install without disturbing walls, ceilings, or day-to-day operations— making them ideal for hospitals, hotels, classrooms, historical buildings, conference rooms, and cubicles. The NJ225-FX can be powered by a "phoenix-style" AC connection common in raceways found in Germany. Alternatively, a local AC adapter, are sold separately. The NJ225 FX can also forward Power over Ethernet to another 802.3af-compatible device, such as a 3Com NBX® Phone. If connections to 100BASE-FX fiber uplinks with ST connections is required, consider the IntelliJack Switch NJ225 FX-ST. Copper uplinks are available with the Switch NJ 225. * Supports QoS-on-Voice with IEEE 802.1p Packet Prioritization to give VoIP traffic and other mission-critical tagged packets priority over non mission-critical transmissions * Improves network performance with advanced switching technologies, including traffic prioritization, multicast rate control, and IEEE 802.1Q VLANs * IEEE 802.1X network login helps restrict access to your network, enhancing security * Supports all IEEE 802.af Power over Ethernet, some nonstandard inline power systems, and local power using an AC adapter; see Product Specifications for details * 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 * Fits a variety of outlets— using optional mounting accessories— including floor mounts and UK double-gang boxes; see Product Options page for a complete listing * 100BASE-FX uplink, with SC connector * Streamlines IT administration with central management that can fine-tune a single port or bulk administer a group of switches * Location Mapping software facilitiates security and manageability; security further boosted with features that include network login support, wall-mounted case, traffic monitoring, SNMP traps, and VLANs Product Specifications * Color: Cream * Ports: Four RJ-45 Fast Ethernet; 100BASE-FX uplink with SC connector * Ethernet Switching: Store-and-forward, full-/half-duplex autonegotiation 10/100Mbps * Local power: 3Com AC adapter (3CNJPSL) required for LANs without Power over Ethernet capabilities * Power forwarding: Forwards power in accordance with IEEE 802.3af, port *4 only; receiving device must be IEEE 802.3af-compliant, or selected phones with the applicable adaptor * Management: 3Com Local/ Central Configuration Managers and Location Mapping utility included; supports SNMP, IEEE 802.1Q VLANs, IEEE 802.1p traffic prioritization/QoS, IPv4, TOS/DifServ; 3Com Network Supervisor recommended * Standards: IEEE 802.1D, 802.1p, 802.1Q, 802.1X, 802.3, 802.3af, 802.3i, and 802.3u; ISO/DIS 8802/3; QoS, SNMP v.1, DHCP; DIN- or BSI 4664:1970-standard outlets with screw separation of 60 mm * Safety, Emissions: CE marking, EN60950, EN55022 Class A, EN55024 * Dimensions: 7.5 cm (3.0 in) high, 7.0 cm (2.8 in) width, 7.0 cm (2.8 in) deep * Temperature: 0o to 35o C (32o to 95o F) operating, -30o to 90o C (-22o to 194o F) storage * Humidity: 10% to 90% operating, 5% to 95% storage (noncondensing) Package Contents * Switch * Mounting screws * Trim ring * Installation CD-ROM with 3Com Local/Central Configuration Manager and Location Mapping software * 5Quick start guide Please Note * Windows 98 or 95 operating systems not recommended for use with management platforms.
