Nortel AL2012E27 BayStack 420 24-Port RJ45 10/100/1000 Base Switch

Stackable 10/100/1000 layer 2 Ethernet switch provides 24 10BASE-T/100BASE-TX auto-sensing ports, 1 GBIC-based (Gigabit Interface Converter) uplink slot, and built-in stacking connectors. Full auto-sensing on every UTP port automatically detects and supports the speed and mode of a connected device-10 Mbps or 100 Mbps, half- or full-duplex. A "plug-and-play" stacking architecture enables up to 8 BayStack 420-24T Switches to be connected with stacking cables into a fail-safe cascade configuration that provides up to 192 ports, managed as a single entity. Wire-speed performance is achieved by a 12.8 Gigabit per second (Gbps) switching fabric and ASICs that support full 802.1D-compliant MAC Layer frame forwarding and filtering across all ports at up to 5.1 million packets per second. GBIC (Gigabit Interface Converter) module options provide a choice of fiber interfaces to connect to distant servers or a larger network, including SX, LX, XD (50 km) and ZX (70 km) for long haul connectivity. MultiLink Trunking (MLT) groups up to four 10/100 uplink ports together to provide up to 800 Mbps of bandwidth, up to 6 MLTs per switch or per stack. Up to 32 port-based VLANs can be established for each switch, to extend the broadcast domain and segment network traffic for higher network efficiency. Standalone or stacked switches can be managed from the Web as a single entity with one IP address, using free software from Nortel Networks-or managed with Nortel Networks Optivity Network Management software. Scale easily as the network grows, by stacking up to 8 units and 192 ports. Built-in stacking connectors make stacking very easy and save money by not requiring additional cascade module. Deliver wire-speed throughput, up to 5.1 million packets per second with no packet loss. Reduce management costs and complexity by managing the switch stack from any Web-connected PC, anywhere in the world- or using Optivity Network Management Software (NMS). Reduce operating costs with a low power consumption of 50 W, 1U high unit that saves space, and auto-sensing ports that eliminate trips to the wiring closet as workstations upgrade to Fast Ethernet Data Rate and Encoding: 10 Mbps: Manchester encoding, 100 Mbps: 4B/5B encoding, 1000 Mbps: 8B/10B Electrical Specifications: Input Volt Ampere Rating: 65 VA maximum, Thermal Rating: 220 Btu/hr Environmental Specifications: Free Fall/Drop Test: ISO 4180-s, NSTA 1A, Vibration: Test IEC 68-2-6
