SummitGbX™ Installation and User Guide This document describes the features and installation of the Summit™ Gigabit Ethernet Fiber-Optic Extender (GbX). SUMMITGbX OVERVIEW The SummitGbX Gigabit Ethernet Fiber Optic Extender greatly increases the maximum single mode fiber interconnect distance between Gigabit Ethernet switches from the standard IEEE 802.3z distance of 500 meters to 80 km (50 miles), or more.

Summary of Features SUMMARY OF FEATURES The SummitGbX extends the distance of Gigabit Ethernet links on Summit and BlackDiamond switches to 80 kilometers using single mode fiber. Depending on the quality of fiber, distances of 100 kilometers, or more, can be achieved.
SummitGbX Front View PORTS The SummitGbX has one 1000BASE-SX port for connecting the SummitGbX to a Summit or BlackDiamond switch, and one single mode long-distance interface (LDI) for connecting between two SummitGbX units. Each 1000BASE-SX and LDI port has one optical transmitter interface (TX) and one optical receiver interface (RX). LEDS Table 1 describes the LED behavior on the SummitGbX.

Installing and Preparing the SummitGbX for Use INITIAL INSPECTION If the shipping container shows signs of damage, keep it, and all packing materials, until the SummitGbX has been thoroughly tested and verified.
Installing and Preparing the SummitGbX for Use RACK MOUNTING The SummitGbX is 1U (1.75 inches) high and fits in a standard 19-inch rack. To rack mount the SummitGbX, follow these steps: 1 Place the SummitGbX on a hard flat surface with the front facing toward you. 2 Remove the existing screws from the left and right sides of the chassis and keep the screws for Step 4. 3 Locate one of the mounting brackets over the mounting holes on the left side of the unit.
Installing and Preparing the SummitGbX for Use POWERING ON THE SUMMITGbX To turn on power to the SummitGbX, connect the power cable to the SummitGbX and then to the wall outlet. Turn the On/Off switch to the On position. CONNECTING EQUIPMENT TO THE SUMMITGbX CONSOLE PORT Connection to the console port, located on the rear of the unit, is used for direct local management.

Managing the SummitGbX USING THE GRAPHIC USER INTERFACE This section describes how to use the GUI to manage the SummitGbX. SYSTEM REQUIREMENTS FOR THE GUI The GUI can be loaded on a PC that meets the following minimum requirements: • Windows 95 or Windows NT version 4.0 • 64 MB RAM • 100 MB disk space • 200 Mhz Pentium CPU • 1.44 Mb 3.
Managing the SummitGbX USING THE GUI To launch the GUI application, double-click the MonitorGbX icon from the Office toolbar. The GbX Monitor window appears, as shown in Figure 6. Figure 6: GbX Monitor window The GbX Monitor buttons are described in Table 5. Table 5: GbX Monitor Buttons and Functions Button Description Com1 Connect GbX Monitor on Com1 to SummitGbX. Com2 Connect GbX Monitor on Com2 to SummitGbX. Disconnect Disconnect GbX Monitor. Login Log in to SummitGbX.
Managing the SummitGbX Table 5: GbX Monitor Buttons and Functions (continued) Button Description Model Info Display SummitGbX model information. Display Loop Back Control Enable/disable loop back control, including LDI loop back and GBE loop back. Change GbX Name Modify SummitGbX name (maximum 11 characters). Request Status Display status information. Request Version Display version information. About Display Extreme Networks information.
Managing the SummitGbX COMMANDS Table 6 describes the CLI commands. Table 6: CLI Commands Command Description Configuration/Status Mode Commands CMD GLE Enable Gigabit Ethernet loopback. CMD GLD Disable Gigabit Ethernet loopback. CMD LLE Enable long distance loopback. CMD LLD Disable long distance loopback. CMD RS? Request status. CMD V? Request software version. CMD ID xxxxxxxxxxx Set unit identification (maximum 11 Characters) CMD I? Display the factory model and serial numbers.
Managing the SummitGbX 2 Type CMD PAS admin, followed by the [Enter] key. The screen displays login complete. STATUS Status messages are sent under several circumstances: • When an error condition occurs. • When an error condition clears. • Approximately every 15 minutes. • When requested by the user. • When power is applied to the unit. The format of the status message is identical in all cases. Figure 7 shows the format of a status response and Table 7 gives a description of each field.
Troubleshooting the SummitGbX Table 7: Status Field Descriptions Column Location Field Text Description Status Column 1-11 User Defined SummitGbX ID NA 13-15 GBE Gigabit Ethernet Interface NA 17-24 RX FLT RX fault (low optical input power) 24 26-36 SYNC LOSS Sync loss (clock recovery failure) 36 38-47 LOOPBACK Loopback enabled 47 49-51 LDI Long distance interface NA 53-60 RX FLT RX fault (low optical input power) 60 62-72 SYNC LOSS Sync loss (clock recovery failure) 72 74
Troubleshooting the SummitGbX 1 Using filtered, compressed air, blow any dust out of the female connector mounted on the SummitGbx. 2 Wipe the tip and sheath of the optical fiber cable (located on the cable connector) with an optical swab that is moistened with optical grade isopropyl alcohol. 3 Wipe the tip and sheath of the optical fiber cable (located on the cable connector) with a dry optical swab. 4 Blow dry with filtered, compressed air.
Troubleshooting the SummitGbX 4 Using an optical power meter, select the appropriate wavelength (780, 1310, 1550 nm) and measure the input power at the ports. Power levels should be above the minimum specified in Table 3. Optical levels should operate about 3dBm greater than minimum levels to provide extra link margin. 5 Check the color of SYNC LOSS LEDs. If one of the SYNC LOSS LEDs is yellow, the Clock/Data Recovery (CDR) was unsuccessful in retiming the data at that input port.
Technical Specifications 4 Reconnect the SummitGbX LDI ports to the optical plant. Using the management interface of the remote SummitGbX, enable LDI Loopback. Verify Loopback Enabled status. The LDI Loop Back LED should be yellow. 5 Using the management interface of the remote SummitGbX, disable LDI Loopback. Verify Loopback Disabled status. The LDI Loop Back LED should be green. Connect the remote SummitGbX GBE TX output to the same SummitGbX RX input using multimode fiber.
