Chapter 1 Introduction The 9E312-12 is a thirteen port switching module with twelve front panel Ethernet interfaces and one Internal Network Bus (INB) backplane interface. This module uses a Fast Packet Switch (FPS) hardware based switch design and an advanced Intel i960® microprocessor. This microprocessor provides a platform for all management functions within a scalable RISC-Based Architecture.
Introduction Features Processor The 9E312-12 is equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions such as Spanning Tree, RMON, and MIB support within a scalable RISC-based architecture. Fast Packet Switching The 9E312-12 incorporates a hardware based switch design referred to as a Fast Packet Switch (FPS), a collection of custom ASICs designed specifically for high speed switching.
Features Management Information Base (MIB) Support The 9E312-12 provides MIB support including: • • • RMON (RFC-1271) IETF MIB II (RFC-1213) IETF Bridge MIB (RFC-1493) and a host of other Cabletron Enterprise MIBs. NOTE For a complete list of supported MIBs, refer to the release notes provided in the 9E312-12 package. INB The 9E312-12 attaches to INB1 of the MMAC-Plus Backplane.

Chapter 2 Installing the 9E312-12 Module The 9E312-12 module occupies two slots in the MMAC-Plus chassis. The module 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.

Pinouts Pinouts The 9E312-12 front panel has twelve RJ-45 Ethernet connections, each of which is internally crossed over. Figure 2-2 illustrates a single RJ-45 Ethernet Connector. Pin 1 Figure 2-2. RJ-45 Ethernet Connector Table 2-1 details the pinout connections for an RJ-45 Ethernet connector. Table 2-1.
Installing the 9E312-12 Module The Reset Switch The reset switch is located on the front panel, under the top plastic tab as shown in Figure 2-3. It serves two functions: resetting the i960 processor and shutting down the module. • To reset the processor, press the reset switch twice within three seconds. • To shut down the module, press and hold the switch down for three or more seconds. To restart the module, press and hold the switch down for three or more seconds.
User Accessible Components User Accessible Components Figure 2-4 shows the various components that can be accessed by users. These consist of an eight position dip switch (explained in the next section), replaceable PROMs, and sockets for memory and flash upgrades. These will be used for future upgrades. Instructions for installing the components will be supplied with the upgrade kit. DIP Switch SMB-1 PROM Boot PROM Flash SIMM Socket Local DRAM Socket i960 Processor Figure 2-4.
Installing the 9E312-12 Module Setting the 9E312-12 Module DIP Switch The DIP switch on the 9E312-12 Module (Figure 2-4 and Figure 2-4), is an eight switch DIP located on the top left corner of the module. Each switch is set according to the functions described in Table 2-2. If switch settings are changed, the processor on the module must be reset by using the reset switch or repowering the module for the changes to take effect.

Setting the 9E312-12 Module DIP Switch See the Cautions at the end of this table. Table 2-2. Function of DIP Switch Function Description Clear Password-1 This module stores user entered passwords in NVRAM (Nonvolatile random access memory). To clear these passwords, toggle this switch and then reset the module’s processor. Once the module resets, factory default passwords are placed in NVRAM. You can use these default passwords or, if desired, enter new passwords.
Chapter 3 Operation The 9E312-12 module is a thirteen port device; twelve front panel ports, each represents a separate Ethernet collision domain and one port connected to INB1.
Operation ENIB The Ethernet Network Interface Block (ENIB) converts Ethernet data packets received through front panel ports into a common canonical format that allows the Fast Packet Switching Engine to determine the proper destination port. The ENIB also converts data packets from the common canonical format back to Ethernet data packets for transmission out front panel ports.
INB NIB INB NIB Each module that attaches to the Internal Network Bus (INB ) has an INB Network Interface Block (NIB). The INB NIB converts canonical frames to fixed length data blocks for transmission onto the INB. For data blocks received from the INB, the INB NIB reassembles the data blocks received from the INB back into canonical frames for transmission to the Fast Packet Switch (FPS) then from the FPS to the front panel ports.
Operation and control the SMB LANVIEW diagnostic LEDs. Although the system diagnostic controller and the main host processor can operate independently of each other if needed, they exchange information about each others status and overall module condition. The information gathered by the diagnostic controller is available to the network manager via local/remote management and the LCD located on the environment module.
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. Shown in Figure 4-1 are the LANVIEW LEDs of the 9E312-12 module.
