Chapter 1 Introduction The 9E531-24 shown in Figure 1-1, is a 10BASE-FL Ethernet switching module for Cabletron Systems SmartSwitch 9000 chassis, providing 24 MT-RJ MMF ports. The 9E531-24 can be used to connect individual 10 BASE-FL user devices and servers. Features Connectivity The 9H532-24 connects to Ethernet networks or workstations through the 24 MTRJ ports on the front panel. These ports are IEEE 802.1D and 802.3 10BASE-FL compliant.

Introduction Duplex Mode Through Local Management, each port on the 9E531-24 can be configured to support either full or half duplex mode of operation. Runtime IP Address Discovery This feature enables the modules to automatically accept an IP address from a Boot Strap Protocol (BootP) server on the network into NVRAM without requiring a user to enter an IP address through Local Management.
Introduction Management Management of the 9E531-24 module and SmartSwitch chassis and any optional equipment is accomplished using the Local Management application or remote SNMP management stations. Local Management is accessible through the RS232 COM port on the Environmental Module using a local VT100 terminal, or a remote VT100 terminal via a modem connection, and in-band via a Telnet connection. In-band remote management is possible through Webview or any SNMP compliant Network Management Software.
Introduction device, and to have it pause its transmission while the receiving device processes the frames already received. Flow control can be enabled or disabled on a port-byport basis. Both devices must support the IEEE 802.3x standard for flow control to work. The 9E531-24 supports the following two types of flow control: • • frame based 802.3x back pressure Frame based 802.3x flow control is supported on all Ethernet ports operating in the full duplex mode.
Introduction Standards Compatibility The 9E531-24 is fully compliant with the IEEE 802.3, 802.3x, 802.1Q, and 802.1p standards. The 9E531-24 provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 9E531-24 supports a wide variety of industry standard MIBs including RFC 1573 (MIB II), RFC 1271 (RMON), RFC 1493 (Bridge MIB), RFC 1354 (FIB MIB), and RFC 1190 (Path MTU Discovery).

Chapter 2 Installing the SmartSwitch 9000 Module Only qualified personnel should perform installation procedures. Unpacking the Module 1. Carefully remove the module from the shipping box. (Save the box and packing materials in the event the module must be reshipped.) 2. Remove the module from the plastic bag. Observe all precautions to prevent damage from Electrostatic Discharge (ESD). 3. Carefully examine the module, checking for damage. If any damage exists, DO NOT install the module.

Installing the SmartSwitch 9000 Module An eight-position DIP switch is located on the module card as shown in Figure 2-1. The function of the switches are listed in Table 2-1. 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.
Installing the SmartSwitch 9000 Module Using DIP Switch 6 The purpose of DIP switch 6 is to force a Flash download from a BootP server through the EM-EPIM. The first step in this process is to configure the BootP server. Configurations of BootP servers can differ from platform to platform and from one operating system to another. Read the user’s manual on BootP and TFTP serving for the correct files to edit and the correct files to execute for the server.
Installing the SmartSwitch 9000 Module 3. Grasp the module and slide it into the slots. Make sure that the module’s circuit card is between the card guides, as shown in Figure 2-2. Check both the upper and lower tracks of the card. Take care that the module slides in straight and engages the backplane connectors properly. 4. Lock down the top and bottom plastic tabs, as shown in Figure 2-2.
Installing the SmartSwitch 9000 Module The Reset Switch The Reset switch is located under the top plastic tab as shown in Figure 2-3. Use the reset switch to reset the module’s processor, shutdown (power down) the module, and/or restart the module. • • • To reset the module’s i960 processor, press the reset switch twice within three seconds. To shut down the module, press and hold the reset switch for three or more seconds. To restart the module, press the reset switch momentarily.
Chapter 3 Technical Overview SmartSwitch Architecture The SmartSwitch Architecture of the 9E531-24 module, as shown in Figure 3-1, is configurable for one of two modes of operation: traditional IEEE 802.1 switching, or SecureFast switching. The module supports only one of these modes of operation at any one time. When operating in traditional IEEE 802.1 switch mode, the 9E531-24 makes filtering/forwarding decisions based on Destination Address (DA), with standard IEEE 802.1D learning. 802.
Technical Overview Figure 3-1. Block Diagram System Management Buses There are two management channels within the SmartSwitch 9000 system: the SMB-1 and the SMB-10. These buses provide out-of-band management and inter-module management communication.
Technical Overview SMB-1 Bus The SMB-1 is a 1 Mbps management bus located within the SmartSwitch 9000. This bus is utilized by all diagnostic controllers in the system including connectivity modules, power supply modules and the environmental module. The SMB-1 transports inter-chassis information between system components, such as power and environmental information, as well as diagnostic messages. Periodic loop-back tests are performed by all modules that share this bus to ensure the validity of SMB-1.
Technical Overview INB Interface Each module attaches to both INB A and INB B and has two INB ASICs. The INB ASICs use 64-byte Ethernet frames for transmission onto the INBs at 66 MHz. The 9X5XX modules are fully compatible with the the first generation 9X4XX modules. The first generation modules communicate only on INB B using a 56-byte canonical frame format, at 40 MHz.
Chapter 4 LANVIEW LEDs The front panel LANVIEW LEDs indicate the status of the module and may be used as an aid in troubleshooting. Figure 4-1 shows the LANVIEW LEDs of the 9E531-24 module.
