Notice FCC Notice This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
Notice Safety Information CLASS 1 LASER TRANSCEIVERS The 9F315-02 is a Class 1 Laser Product CLASS 1 LASER PRODUCT The 9F315-02 uses Class 1 Laser transceivers. Read the following safety information before installing or operating these adapters. The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the need for maintenance checks or adjustments. The output is factory set, and does not allow any user adjustment.
Notice Safety Information CLASS 1 LASER TRANSCEIVERS Laser Radiation and Connectors When the connector is in place, all laser radiation remains within the fiber. The maximum amount of radiant power exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10-6 watts. Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum radiance from the optical port (under worst case conditions) is 0.8 W cm-2 or 8 x 103 W m2 sr-1.

Chapter 1 Introduction The 9F310-02 and 9F315-02 are three port switch modules with two front panel FDDI interfaces and one INB-1 backplane interface. The external FDDI networks are connected to the modules using standard FDDI A/B ports on the front panel. The 9F310-02 uses multi mode fiber, and the 9F315-02 uses single mode fiber optic cables for this connection. The 9F310-02 and 9F315-02 modules employs the Fast Packet Switch (FPS), a high performance switch design, and the Intel i960 microprocessor.
Introduction interfaces provide frames filtered, frames forwarded, and all Spanning Tree Protocol parameters. The 9F310-02 and 9F315-02 modules support the IETF FDDI MIB (RFC-1512), IETF MIB ll (RFC-1213), IETF BRIDGE MIB (RFC-1493), and a host of Cabletron enterprise MIBs. In addition, the front panel provides LEDs for FDDI link status per port as well as transmit and receive activity.

Chapter 2 Installing the MMAC-Plus modules The 9F310-02 and 9F315-02 modules occupy two slots in the MMAC-Plus chassis. The modules must be installed with the left side (as viewed from the front) in an odd numbered slot, and the right side in an even numbered slot. NOTE The INB Terminator Modules must be installed on the rear of the chassis before powering up this module. Refer to the INB Terminator Modules Installation Guide for information and installation procedure.

Lock down the top and bottom plastic tabs at the same time, applying even pressure. Figure 2-1.
The Reset Switch The Reset Switch The Reset switch is located on the rightmost front panel, under the top plastic tab as shown in Figure 2-2. It serves two functions: • • Pressing the reset switch twice within three seconds causes the processor (i960) to reset. Pressing and holding the switch on for three or more seconds causes the module to shutdown. Pressing and holding again for three seconds restarts the module. SNMP management may be used to disable this switch to enhance module security.
Installing the MMAC-Plus modules User Accessible Components Figure 2-3 shows the various components that are accessible to the user. These consist of an eight position dip switch (explained below), replaceable PROMs and sockets for RAM. These will be used for future upgrades. Instructions for installing the components will be supplied with the upgrade kit. SMB-1 PROM DIP Switch Boot PROM Flash SIMM Socket Local DRAM Socket i960 Processor 8 7 6 5 4 3 2 1 Figure 2-3.
User Accessible Components See the Cautions at the end of this table. Table 2-1. Function of DIP Switch Switch Function Description 8 Clear Password 1 When toggled, this switch clears user-entered passwords stored in NVRAM, and restores the default passwords. Once reset you can use the defaults or enter new passwords. Clear NVRAM 2 The module uses NVRAM to store user entered parameters such as IP addresses, device name, etc. To reset these parameters to the factory defaults, toggle this switch.

Chapter 3 Operation The 9F310-02 and 9F315-02 modules are capable of bridging/switching any three, of five possible interfaces, depending on how it is configured. The INB-1 connection is always fixed. When configuring the module, the decision is made to connect both front panel ports, both FNB ports, or one front panel and one FNB port to the bridge.
Operation System Management Buses There are two management channels within the MMAC-Plus system: the SMB-1 and the SMB-10. These buses provide out-of-band management and inter-module management communication. SMB-1 Bus The SMB-1 is a 1Mbs management bus located within the MMAC-Plus. This bus is utilized by all diagnostic controllers in the system including connectivity modules, power supply modules and the environmental module.
DC/DC Converter DC/DC Converter The DC/DC converter converts the 48 VDC on the system power bus to the necessary operating voltages for its host network services module. The diagnostic controller monitors and controls the operation of the DC/DC converter. INB Interface Each module that attaches to the INB has an INB Network Interface Block (NIB). The INB NIB converts canonical frames to fixed length data blocks for transmission onto the INB.
Operation The Host engine sends and receives packets via the CPU FPS Interface. This allows the bridge to perform spanning tree protocol and other bridging functions. The SMB Interfaces provide communication to the Host Engine for management functions and communication with other modules in the chassis.
Chapter 4 LANVIEW LEDs The front panel LANVIEW LEDs indicate the status of the module and may be used as an aid in trouble shooting.
