CAUTION: Verify that the module screws are properly aligned with the threaded holes in the chassis. If the screws are not aligned when you tighten them, you may strip the threads and make it impossible to secure the module. To ensure that you tighten screws to torque specification, use a torque screwdriver. WARNING: To ensure adequate cooling airflow and continued product safety agency compliance, install blank faceplates over all empty slots. If the chassis is powered on, the module initialization process begins. 20 10-Port 100BASE-FX and 20-Port 10/100BASE-TX Fast Ethernet Layer 2 Switching Modules Quick Start Guide 20 10-Port 100BASE-FX and 20-Port 10/100BASE-TX Fast Ethernet Layer 2 Switching Modules Quick Start Guide Verifying Module Operation The 10-port 100BASE-FX FEN Switching Module has 10 Port Status LEDs and the 20-port 10/100BASE-TX FEN Switching Module has 20 Port Status LEDs. Each module has one Module Status LED. Watch the LEDs during the system power-on diagnostics test to verify proper module operation: ¦ On the Module Status LED, the normal power-on test sequence is Green – Yellow – Green – Flashing Green (while running the diagnostic test) – Green If the Module Status LED is Yellow after the diagnostics run, the module has failed. ¦ The Port Status LEDs are tested during the diagnostic test. The normal test sequence is Yellow – Green – Off Table 11 describes LED colors and definitions. Table 11 Module and Port Status LED Indicators LED State or Color Definition Module Status Green Power is on (normal operation). Flashing Green Diagnostics or software download is in progress. Yellow Off Diagnostic failure. After initial insertion or module reset, the LED remains unlit for approximately 3 seconds. Otherwise, an unlit LED indicates that the module is not receiving power. Port Status Green Flashing Green Port is enabled and link is up. Port is receiving or transmitting packets. Yellow Off Module or port is malfunctioning. Port is disabled or link is down. 10-Port 100BASE-FX and 20-Port 10/100BASE-TX Fast Ethernet Layer 2 Switching Modules Quick Start Guide 21 10-Port 100BASE-FX and 20-Port 10/100BASE-TX Fast Ethernet Layer 2 Switching Modules Quick Start Guide 21 Managing the Module 1 2 3 You configure and manage a FEN Switching Module using several interfaces. The following sections describe two of the interfaces. Administration Console The Administration Console is the embedded menu-driven command line interface that you access from a terminal or through terminal emulation software. To manage the module from the Administration Console: Log in to the EME. For information about how to log in to the EME, see the CoreBuilder 9000 Enterprise Management Engine User Guide. At the EME prompt, enter: connect .1 where is the chassis slot number of the module that you want to manage, and the number after the decimal point is a subslot number, which is always 1. The top level of the Administration Console menu for the module appears. Enter command strings to manage the module. For example, to display a module baseline, enter: module baseline display For information about the Administration Console module commands, see the Command Reference Guide. Web Management Web Management applications are an embedded part of the system. They include WebConsole, DeviceView, and Performance monitoring tools. Additional installable applications include online Help. After you have set up the IP address for your system, you can access the Web Management applications directly in your Web browser by entering the IP address. For information about setting up your IP address, see the Enterprise Management Engine Quick Start Guide for the CoreBuilder 9000 Enterprise Switch. For additional information about Web Management, see the Web Management User Guide for the CoreBuilder 9000 Enterprise Switch. 22 10-Port 100BASE-FX and 20-Port 10/100BASE-TX Fast Ethernet Layer 2 Switching Modules Quick Start Guide 22 10-Port 100BASE-FX and 20-Port 10/100BASE-TX Fast Ethernet Layer 2 Switching Modules Quick Start Guide Module Specifications The following tables list specifications for the 10-port 100BASE-FX and 20-port 10/100BASE-TX Fast Ethernet Layer 2 Switching Modules: Cabling Requirements Module 100BASE-FX (3CB9LF10MC) Required Cable Type Multimode fiber 62.5/125 micron Maximum Segment Length Half-duplex mode: 400 m (1312 ft Full-duplex mode: 2 km (1.2 mi) 10/100BASE-TX UTP Category 5 Up to 100 m (328 ft) (3CB9LF20R) Environmental Requirements Operating temperature 0 to 50 ° C (32 to 122 ° F) Operating humidity 10% to 90% relative humidity, noncondensing Storage temperature –40 to 66 ° C (–40 to 151 ° F) Storage humidity 5% to 95% relative humidity, noncondensing Physical Specifications Module Dimensions Weight 100BASE-FX 25.4 mm x 340.36 mm x 388.112 mm 1.135 kg (3CB9LF10MC) (1 in. x 13.4 in. x 15.28 in.)
