70 -- INTELLIGENT NETWORK HUB SOL N66604-96-R-A235 DUE 121195 POC Contact Elaine Medeiros, Contracting Officer at (401) 841-2442 X282 FAX: (401) 841-4820 (PART I OF II) The Naval Undersea Warfare Center Division, Newport, Rl, intends to acquire two Intelligent Network Hubs systems, with spares, consisting of the components described below, on a brand name or equal basis. The following items contain Cabletron Systems, Inc. part numbers: 0001 8-Slot MMAC Hub, part number MMACM8FNB, 2 each. 0002 Enhanced Power Supply Module for MMAC-8FNB, part number MMAC-M8PSM-E, 5 each. 0003 Four-Port Ethernet Management Bridging Module, part number EMME, 5 each. 0004 Thin Coaxial Module with 12 BNC Ports, part number THN-MIM, 5 each. 0005 10Base-2 Multichannel Repeater MIM, part number CXRMIM, 7 each. 0006 FDDI Bridge and Management MIM {DAS), part number FDMMIM, 7 each. 0007 Optical Bypass Switch for FDMMIM, part number FDDI- OBS, 7 each. 0008 Thin Ethernet Transceiver, part number TMS- 3, 12 each. 0009 Standard Support Plan for Items 1 through 8, part number NETCARE STND, 1 each. COMPATIBILITY STATEMENT: The Cabletron Systems, Inc. Intelligent Network Hub was chosen competitively for use in the Combat Control System (CCS) MK 2 Block l A/B Upgrade task to replace expensive MILSPEC hardware with Commercial Off-The- Shelf (COT) hardware in new submarine combat system development programs. The network system is in the process of being integrated on CCS Mk 2 Block 1 A/B submarine platforms. NUWC's development effort, based on network integration of the Cabletron hub, is approximately 36 man-months valued at $360,000.00, which resulted in development of numerous system specifications, ship installation plans, and engineering/performance studies based on the hubs physical and electrical specifications (size, weight, power consumption, cabling methods, performance, etc.) If a noncompatible network hub were used that does not match the Cabletron MMAC network hub specifications, additional costs to the Government are estimated as follows: NUWC Development Efforts $360,000.00. Ship Alteration (SHIPALT) plans and drawing rework at an estimated cost of $225,000.00. Impacts to existing Government contracts estimated at $320,000.00 based upon contract renegotiatin and Government Furnished Information (GFI) changes. Total cost impact to the CCS MK 2 Block 1 A/B Program if any other vendor's network is used that is not compatible with Cabletron Systems, Inc. MMAC Intelligent Network Hub is $905,000.00. SALIENT CHARACTERISTICS: 0001 The large capacity modular intelligent wiring hub (MMAC-M8FNB} shall at a minimum meet the following requirements: --Designed in accordance with UL478, UL910, NEC725-2(b), CSA, IEC, TUV, VDE Class A and meet FCC Part 15, Class A limits. --Shall operate in a standard office or wiring closet environment (Operating Temperature +5 degrees Centigrade (deg C) to +40 deg C, Non-Operating Temperature: -30 deg C to +80 deg C, 5%-95% relative humidity, non- condensing) and shall not require any special heating or cooling requirements. Hub shall operate on standard 110 Volts 50/60 Hz electric current. Power shall not exceed 1500 watts. --Shall provide generic backplane architecture to allow the simultaneous support for multiple standards based LAN topologies. At a minimum, it must support three IEEE 802.3 Ethernet LANs, two 802.5 Token Ring LANs and two ANSI X3T9.5 FDDI networks. --Capable of being mounted into a standard 19-inch rack in accordance with EIA RS-343 and shall be no higher than 15 inches and no deeper than 18 inches. --Shall weigh no more than 25 pounds. --Must provide 183+ ports for node connectivity while providing SNMP management and redundant power supplies. --Must provide all data connections with a redundant back up path in the event of a data path failure. --Must have the capability to support at least four separately bridged Ethernet segments. - Must provide separate Ethernet, Token Ring and management busses. --Must utilize a passive backplane architecture (no resistors or capacitors). --Must allow the swapping of media interface and power supply modules without causing any disruption to users on the network (Hot Swapping). --The management, interface and power supply modules must each provide LED diagnostic indicators. --Must provide local and remote SNMP management capability. --Shall have a Mean Time Between Failure (MTBF) greater than or equal to 7,000,000 hours. --Shall have redundant power supplies with load sharing capabilities and visual and audible status indicators for power on/off, over/under temperature, and over/under voltage sensing. An error message shall be sent to the network management statio indicating a power supply fault via SNMP. --Must provide removable fan tray accessible from the front of the unit for maintenance and periodic cleaning. A front mounted visual status indicator shall be provided indicating a fan failure. In addition, an error message shall be sent to the network management station via SNMP. --Must have the capability to support Ethernet via multimode and single mode fiber optic media using ST type connectors and without the need for external media converters. The following must be available: Ethernet to Ethernet bridge module, Ethernet to Token Ring bridge module, Ethernet to FDDI bridge module, Ethernet to Ethernet router module, Ethernet to FDDI router module, Ethernet to WAN router module, Ethernet to LocalTalk gateway or router module, Ethernet to WAN bridging module with multiplexing capability, and Ethernet Terminal Server interface module. --Media Modules for these topologies shall be capable of supporting media options that are in conformance with existing standards.
