AT-4016F Installation Manual ATI’s Solution In the past, a legacy Ethernet-to-Ethernet switch partially resolved fundamental bandwidth congestion problems by assigning each node to a unique segment. That was yesterday. Unfortunately, legacy Ethernet-to-Ethernet switching is not a total solution to bandwidth congestion when it originates from the backbone or if you (and others at the same time) access a server or data base which is outside your local network.
Overview Figure 3 shows the front panel of an AT-4016F/ST. Figure 3: AT-4016F/ST Front Panel Figure 4 shows the Ethernet-to-ATM modular media interface which is located on the back panel. Both the AT-4016F/SC and the AT-4016/ST have identical back panels.
AT-4016F Installation Manual Figure 5 shows a close-up of the ATM Media Module faceplate using an SC connector. Figure 5: ATM Faceplate Without a media module installed, or installed but not used, the AT-4016F operates as a standalone Ethernet switch. When ordered factory-installed, the media module version is indicated by the third digit in the model name suffix. You can also order additional ATM Physical Media Modules separately for different media requirements.
Overview MIB Support The following Management Information Base (MIB) protocols are supported by ATI’s AT-4016F Omega Management Software. ❑ SNMP MIB2 (RFC 1213) ❑ Ethernet MIB (RFC 1643) ❑ Partial Bridge MIB (RFC 1493) ❑ ATM Forum ILMI MIB Ethernet-to-Ethernet Switch Your AT-4016F combines Ethernet-to-Ethernet device switching with Ethernet-to-ATM backbone/server connectivity.
AT-4016F Installation Manual Selector Byte The selector byte is used to denote specific ELAN membership. [network prefix] [MAC address] [selector byte] Selector bytes consist of integers ranging from 00 to 64 and includes a “Super LEC.
Overview Each ATM MAC address is created by adding the port number to the basic AT-4016F MAC address. Since the AT-4016F has 16 ports there are 16 MAC addresses: Port #1 - [basic MAC address + 01] Port #2 - [basic MAC address + 02] * ** *** Port #16 - [basic MAC address +16] Two Modes of Ethernet Switching There are two popular methods to forward information: cut-through and store-and-forward. Although your AT-4016F employs store-and-forward as the default, you can also choose cut-through.
AT-4016F Installation Manual Bridging Your AT-4016F acts as a transparent bridge to the Ethernet ports and the ATM interface. As such, it learns the source MAC address of all incoming packets and ages out devices which have not been heard for a period of time. Bridging involves a forwarding table with a maximum storage capacity of 2,048 MAC address. These addresses are associated with all devices that have been detected recently either from Ethernet ports or the ATM interface.
Overview Each entry which is automatically entered (a dynamic entry) includes: ❑ An Ethernet MAC address ❑ The port number of the LAN on which the address resides ❑ The age of the entry ❑ ELAN/VLAN membership Each entry which is manually entered (a static entry) contains the same information as a dynamic entry, except that a static entry is not aged. The AT-4016F can store up to 2,048 static and dynamic entries in its Bridge Address Table.
AT-4016F Installation Manual AT-4016F/ST The AT-4016F/ST has Straight Tip (ST) connectors which mate through a two-pin, bayonet-style interface. ST connectors are popular simply because they have less attenuation and less vulnerability to human error than previous fiber optic connectors such as a Sub Miniature Assembly (SMA).
Overview AT-4016F/SC The AT-4016F/SC has Subscriber Channel (SC) connectors which mate through a square push-pull interface. SC connectors represent, for many individuals, an improvement over ST connectors in that they have a lock proof mechanism. Figure 10 shows the front panel of an AT-4016F/SC. Figure 10: AT-4016F/SC Front Panel Figure 11 shows an SC connector matrix with the locking device removed and suspended over the connectors.
AT-4016F Installation Manual Figure 12 shows an SC connector group with the locking device installed. Figure 12: AT-4016F/SC Connector With Lock FOIRL, 10Base-FL Wiring Specifications The IEEE FOIRL standard limits a fiber segment length to 1 km (1,000 meters or 3,280 feet). That is, the fiber optic cable that connects two repeaters is limited to 1 km (3,280 ft.). While the more recent IEEE 802.3 10Base-FL standard is compatible with FOIRL, it can travel up to 2 km.
Overview Configuration Rules Depending on the medium you choose, there are certain wiring practices you must follow to ensure the reliability of communication throughout the network. The AT-4016F complies with IEEE standards for 802.3 CarrierSense Multiple-Access with Collision Detection (CSMA/CD) Ethernet and with ATM Forum UNI Specification 3.0; you should refer to these standards when implementing your network. Power Supply The AT-4016F offers two redundant, removable, load-sharing power supplies.
Chapter 2 Installation Site Preparation Note Before installing the AT-4016F Ethernet Switch with ATM Access, read the “Electrical Safety and Installation Requirements” on page i.

AT-4016F Installation Manual Installing the Redundant Power Supplies The AT-4016F has a redundant, dual power-supply. See Table 3 in Chapter 1 for the list of AT-4016F models. Power supply modules are keyed so that they will only fit in the appropriate switch housing. The following procedure details how to replace an AT-4016F power supply. Replacing a power supply Caution When inserting or removing power supplies using the hot swapping method, the power cord should remain plugged in. 1.
Installation Media Module Installation ATM Physical Media Modules are available in several versions for differing network requirements. Installing ATM Media Modules ATM Media Modules plug into the Media Channel connector located on the AT-4016F back panel. Attention You must disconnect the AT-4016F from its power source to install or swap ATM Media Modules. 1. Disconnect the AC power cord from the AT-4016F. 2. Unplug any data cables connected to the current ATM Media Module.
Chapter 3 Connectivity This chapter describes network hardware functions. The first two sections cover the layout of the front and back panels. The rest of the chapter covers the functionality of the different components: connectors, indicators and switches. Front Panel An AT-4016F/SC front panel is shown in Figure 15.
Connectivity The front panel includes the following components: ❑ 16 Fiber Optic — either SC or ST — station ports ❑ RS232 Terminal Port ❑ PCMCIA Flash Memory slot ❑ Recessed Reset Switch ❑ Diagnostic LEDs: — Network Loading indicators — ATM Port indicators — Individual Fiber Optic Port Interface indicators — ATM Media Alarms and Power Supply indicators Back Panel An AT-4016TR/SC back panel is shown in Figure 16.
AT-4016F Installation Manual AT-4016F Ports Station Ports There are 16 Fiber Optic station ports which can be used to connect to workstations, servers or hubs. RS232 Terminal Port The AT-4016F includes an RS232 Terminal Port on the front panel. The principal use for this port is the connection of a local network management terminal to access ATI’s Omega agent.
Connectivity LED Displays The AT-4016F has four types of LEDs: System Status LEDs ❑ System Status indicators show the overall condition of the switch ❑ Power Supply Indicators ❑ Port indicators shows information about each Fiber Optic port connection.
AT-4016F Installation Manual Power Supply LEDs Figure 19 shows the Power Supply LEDs. Figure 19: Power Supply LEDs PS Present 1 (Green)—Indicates Power Supply #1 is installed. PS Present 2 (Green)—Indicates Power Supply #2 is installed. PS Fail 1 (Amber)—Indicates Power Supply #1 has failed. This means that there is either an inadequate, or nonexistent, amount of AC voltage. PS Fail 2 (Amber)—Indicates Power Supply #2 has failed.
Connectivity Fiber Optic Port LEDs The port indicators on the AT-4016F front panel provide visual diagnostic and activity information for network analysis. Each Fiber Optic port supports the following indicator functions with three front panel LEDs per port, arranged in a central bank as shown in Figure 20. Figure 20: Port Indicators LINK (Solid Green)—This indicates that the particular port has a valid link and is not partitioned.
AT-4016F Installation Manual ATM Interface LEDs The AT-4016F supports an additional set of indicators that convey diagnostic and status information about the ATM Physical Interface. The location of these indicators is shown in Figure 21. Figure 21: ATM Interface LEDs ATM Port LEDs ONLINE (Solid Green)—Indicates that the ATM Physical Interface is active (enabled). SYNC (Synchronization) (Solid Green)—Indicates that the ATM Physical Interface has synchronization.
Connectivity ATM Media Module LEDs A further set of indicators appears on the ATM Media Module. Located on the back panel of the AT-4016F, these LEDs convey diagnostic and status information specific to the type of media connection that has been installed. The location of these indicators is shown in Figure 22. A brief discussion of their functions follows. Figure 22: ATM Media Module LEDs FAIL (Amber)—This LED indicates that the ATM Media Channel has failed self-test or is disabled.
AT-4016F Installation Manual Reset Switch Located at the far left of the front panel (as shown in Figure 23), this switch is recessed to avoid inadvertent activation. To press the switch, insert the tip of a pen or similar object into the access hole. Figure 23: Reset Switch The Reset switch initiates the same diagnostic self-testing cycle which takes place when you initially apply power to the system.
Chapter 4 Troubleshooting Troubleshooting the Installation This section provides a checklist for resolving problems associated with your AT-4016F and cabling. The first rule of troubleshooting is to isolate the problem. As you experiment, only vary one factor at a time. Substitute known good equipment and see if the problem persists or is eliminated. As a preliminary check, perform the following steps 1.
Appendix A Glossary 10BASE-T—IEEE 802.3 UTP Ethernet. Low-cost Level 3 or better UTP wiring affords 100 meters (328 ft.) of point-to-point link segments. UTP uses RJ-45 connectors and sometimes 50-pin AMP connectors to a patch panel and runs at 10 MHz. ADDRESS RESOLUTION PROTOCOL (ARP)—The procedures and messages in any communications protocol which resolve local addresses to those of the network. In TCP/IP, the protocols for translating between IP addresses and physical addresses.
Glossary CARRIER SENSE MULTIPLE ACCESS with COLLISION DETECT (CSMA/CD)—This is the access method employed by IEEE 802.3 LAN transceivers, by which multiple stations compete for use of the transmission medium (coax cable) for data packet transmission. It provides for a level of error detection should that transmission be corrupted or impeded by contention for the transmission medium.
AT-4016F Installation Manual HUB/REPEATER—A hub is a central signal distributor. It is used in a wiring topology consisting of several point-to-point segments originating from a central point. The term hub is often used interchangeably with the term repeater. Multiport 10Base-T, 10Base2 and fiber optic (10Base-FL, FOIRL) repeaters are considered hubs. See Repeater. HUB-to-HUB WIRING—See MAU-to-MAU Wiring HUB-to-MAU WIRING—UTP cables for 10Base-T hub-to-MAU or NIC cards are wired straight-through.
Glossary MAU-to-MAU, HUB-to-HUB WIRING—10Base-T MAU-to-MAU or hub-to-hub wiring generally requires a crossover cable located somewhere along the UTP cable run. This may commonly occur at the punch-down block or between the RJ-45 wall receptacle and the workstation. MAU/TRANSCEIVER—An Ethernet transceiver is a MAU. A 10Base-T MAU interfaces the UTP media to an AUI port on a workstation, repeater, bridge or other Ethernet device.
AT-4016F Installation Manual PROPAGATION DELAY—The time it takes a signal to travel from the input of a system component to the output. Usually measured in nanoseconds. IEEE 802.3 has specific propagation delay maxima for computing propagation budgets when designing a LAN. Cable length plays a major role in propagation delay; for example, a 50-meter (164-foot) AUI cable has a maximum allowable propagation delay of 257 ns.
Glossary SWITCHED VIRTUAL CIRCUIT (SVC)—A virtual circuit (X.25), virtual connection (Frame Relay) or virtual channel connection (ATM) that has been established dynamically in response to a signaling request message. SWITCHED LAN—Emerging technology that replaces the shared bus backplane of Ethernet hubs and the shared ring backplane of token Ring hubs with a switching backplane. Connectivity is provided by switching sender traffic directly to the port of the addressed destination device.
