Introducing the BNC Module Introducing the BNC Module The Asanté 2072 BNC multiport repeater module is a single-slot card that plugs into any slot in the AsantéHub 2072 chassis. As a separate repeater/retiming unit, this module continues to function even if other modules malfunctions in the same chassis.
AsantéHub 2072 BNC Module Installation Guide Installation Grounding Requirements Checking Package Contents Required Tool Page 4 The BNC module installation consists of a few basic steps: ❏ Grounding yourself ❏ Checking the package contents ❏ Installing the module and checking the LEDs ❏ Connecting the module to other devices Before unpacking or handling the module, you must attach the grounding strap provided to your wrist and then touch the rack mount or a piece of metal to discharge static electrici
Installation Installing the BNC Module This installation assumes that you have already installed the 2072 chassis. To install the 2072 BNC Module, do the following steps: Make sure the Asanté 2072 Hub’s power is turned on. Having the power already turned on allows the LEDs on the module to light when installed. 1 2 Observing the anti-static procedures, remove the module from its anti-static packing. ❖ Note: Handle the module only by its edges. Do not touch chips or connectors.
AsantéHub 2072 BNC Module Installation Guide The Front Panel The BNC Module front panel provides the following LEDs and connectors: ❏ AUI connector ❏ AUI Uplink LEDs ❏ Ten 10Base2 connectors ❏ Link/Receive LEDs ❏ Segment LEDs (1 and 2) Figure 3 illustrates the BNC Module front panel;Table 1 lists and defines the BNC module LEDs and connectors.
Interpreting the LEDs Interpreting the LEDs The LEDs give information about the status of a particular unit or function. Each 2072 BNC Module has a set of 10 link/partition LEDs which display port status. In addition, there are two LEDs which represent AUI Port Link and Partition status, and two LEDs used to indicate on which Ethernet segment the repeater card is configured.
AsantéHub 2072 BNC Module Installation Guide Cable Connections to Other Devices The BNC Module provides two types of connectors for attachment to other devices, such as other hubs, PCs, and Macs: ❏ AUI connector for attachment to the backbone and other hubs (recessed mini- MAU included with double-slot version ❏ BNC connectors (ten 10Base2 ports) for attachment to network devices Using the AUI to Connect to the Backbone The AUI port (DB15 pin connector) is typically used to interconnect hubs using an Et
Cable Connections to Other Devices Using the AUI to Interconnect Hubs You can interconnect hubs using the AUI Uplink port located on the module’s front panel. Asanté provides an RJ45, BNC, and 10BaseF Mini MAU to accommodate your backbone cabling scheme. To interconnect hubs using the AUI Uplink port, attach a MAU to the AUI port on the module’s front panel of the first hub. Attach a cable appropriate for the MAU you are using. Attach another MAU to the AUI port on the second hub.
AsantéHub 2072 BNC Module Installation Guide Using the BNC to Connect to a Management Station To connect the BNC Module to a network management station (PC or Mac) for an in-band connection, attach one end of a thin Ethernet cable to a BNC port on the module’s front panel. Connect the other end of the thin Ethernet cable to a T-connector, and then connect the T-connector to either a PC or Mac. See Figure 6.
Technical Specifications Technical Specifications The BNC Module technical specifications are as follows: Standards Supported: IEEE 802.3 Ethernet specifications for thin Ethernet (10Base2) media. Data Rate: 10 Mbps Maximum Cable Distances: 10Base2 (thin) -- 185m (605 ft.) This maximum distance is on a per port basis. Each of the ten ports supports up to 29 devices on a total cable length of up to 185 meters.
