Notice Safety Information CLASS 1 LASER TRANSCEIVERS The GPIM-F01 is a Class 1 Laser Product CLASS 1 LASER PRODUCT The GPIM-F01 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 2 Installing the 9G426-02 Module This chapter describes the physical layout of the 9G426-02 Module and explains how to prepare and install the module in an MMAC-Plus chassis. ! CAUTION Never expose the module’s components to Electrostatic Discharge. Make sure you have attached the module’s disposable grounding strap to your wrist and always place the module on a non-conductive surface. The 9G426-02 module occupies a single slot in the MMAC-Plus chassis.
Installing the 9G426-02 Module The Module’s Physical Layout The 9G426-02 Module has two major circuit boards on which components are attached (see Figure 2-1). The module’s base-level circuit board is known as the motherboard. The module’s second-level circuit board is known as the daughterboard. The removable daughterboard attaches to the motherboard’s connectors and standoffs. Both the motherboard and the daughterboard contain components that are accessible to the user.
Installing the 9G426-02 Module User Accessible Components on the Module’s Daughterboard The user accessible components on the module’s daughterboard are located on the underside of the daughterboard. These components include an eight position DIP switch, a replaceable SMB-1 PROM, a replaceable BOOT PROM, and sockets for DRAM and FLASH memory. You can access the DIP switch without removing the daughterboard.
Installing the 9G426-02 Module 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 the passwords are reset, you can use the defaults or enter new passwords. 7 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.
Installing the 9G426-02 Module Removing the daughterboard from the motherboard To remove the module’s daughterboard from the motherboard: 1. Place the module (component side up) on a non-conductive, flat surface. Position the module so that the module’s front (faceplate) is to the left and the module’s back (backplane connectors) is to the right. The daughterboard abuts the backplane connectors (see Figure 2-1). 2. Locate the daughterboard’s nine securing screws (see Figure 2-3). 3.

Installing the 9G426-02 Module SMB-1 PROM The 9G426-02 Module is shipped with an SMB-1 Firmware PROM. The SMB-1 Firmware PROM is located on the underside of the module’s daughterboard as shown in Figure 2-4. To upgrade the SMB-1 PROM, install the SMB-1 PROM Upgrade Kit. Installation instructions are included in the upgrade kit. BOOT PROM The 9G426-02 Module is shipped with a BOOT PROM. The BOOT PROM is located on the underside of the module’s daughterboard as shown in Figure 2-4.
Installing the 9G426-02 Module Installing the Module into the MMAC-Plus Chassis To install the 9G426-02 Module into the MMAC-Plus Chassis, follow the steps below: NOTE To insure proper data transmission from the 9G426-02 Module to the INB on the MMAC-Plus backplane, two INB Terminator Modules must be installed on the rear of the MMAC-Plus chassis . Refer to the INB Terminator Module Installation Guide for information and installation procedure. 1.

Installing the 9G426-02 Module The Reset Switch The Reset switch is located on the front panel, under the top plastic tab as shown in Figure 2-6. It serves three functions: resetting the i960 processor, shutting down the module, or restarting the module. • • • To reset the i960 processor, press the reset switch twice within three seconds. To shut down the module, press and hold the reset switch down for three or more seconds.

Chapter 3 Operation The 9G426-02 module is a two port Gigabit Ethernet device. Two front panel GPIMs support Ethernet connectivity through a Fiber channel and are capable of providing MMF connectivity through SC connections.
Operation All data packets destined for a front panel port, the INB, or the i960 are converted into the canonical format before forwarding to the SmartSwitch ASIC. Network Interface Blocks (NIBS) check for valid data packets entering the system. If an errored data packet is found, the SmartSwitch ASIC flags the error and does not forward the errored data packet to any outbound ports. Once in this common format, the SmartSwitch ASIC decides from header information the port destination of data packets.
Operation A VLAN is a local area network of endpoints having full connectivity (sharing broadcast, multicast, and unicast packets) independent of any particular physical or geographical location. In other words, endpoints that share a virtual LAN appear to be on a single LAN segment regardless of their actual location. Changes to VLANs (e.g., moving nodes) are accomplished via software , which reduces network management time and expense.
Operation VLAN Domains VLAN domains consist of groups of interconnected VLAN switches separated by routing devices. Figure 3-3 shows such an arrangement. Each group of switches constitutes a VLAN domain. Routing Device VLAN Domain VLAN Domain SFS Network SFS Network VLAN Switch VLAN Switch VLAN Switch VLAN Switch VLAN Switch VLAN Switch Figure 3-3. VLAN Domains Fully Meshed VLAN Domains The switches shown in figure 3-3 above are said to be fully meshed.
Operation SecureFast VLAN Switches SecureFast VLAN (SFVLAN) switches are connection-oriented internetworking devices. These devices use source address/destination address (SA/DA) pairs along with embedded layer 3 virtual routing services to provide address resolution and call processing. In a connection-oriented network, path determination is accomplished through signaling performed at call setup time. Once a call is programmed, no additional software intervention is required until the call is completed.
Operation System Management Buses There are two management channels within the MMAC-Plus system: the SMB-1 and the SMB-10. These buses provide side-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.
Operation 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 The INB Backplane is designed to transport fixed length data blocks between modules in the MMAC-Plus using a Time Division Multiplexing (TDM) design. The MMAC-Plus INB bus delivers 2.
Operation ITDM RAM Allocation (Level 1) This level guarantees access to the backplane. When a module requests access to the backplane, it will get access to it when it's slot number is placed onto the bus. This will ensure predicted or predetermined access to the backplane. Round Robin Arbitration (Level 2) This level makes use of idle time slices. There is a token passed on every time slice to modules participating in this level of arbitration. Only one module has the token at any one time slice.
Chapter 4 LANVIEW LEDs The front panel LANVIEW LEDs indicate the status of the module and may be used as an aid in troubleshooting. Shown in Figure 4-1 are the LANVIEW LEDs of the 9G426-02 module.
