Need Some Troubleshooting Advice on the Summit GBX?

Optical Connector Cleaning

Connecting damaged or dirty optical fibers to the Summit GbX will damage the connectors and the internal optics. Follow these steps for proper cleaning:

Using filtered, compressed air, blow any dust out of the female connector mounted on the SummitGbx.
Wipe the tip and sheath of the optical fiber cable (located on the cable connector) with an optical swab (Lint-Free Swab) that is moistened with optical grade isopropyl alcohol. (Do not use rubbing alcohol!!!)
Wipe the tip and sheath of the optical fiber cable (located on the cable connector) with a dry optical swab.
Blow dry with filtered, compressed air

Link Troubleshooting

Clean the optical connectors, as described previously.
Make sure that the connectors are plugged in correctly on both ends of the link.
Verify that the RX FLT LEDs (GBE and LDI) on the SummitGbX chassis are green onboth ends of the link. An RX fault can be caused by incorrectly connected fibers (for example, TX-to-TX,) dirty or damaged connectors, or damaged fiber.
Using an optical power meter, select the appropriate wavelength (780, 1310,1550 nm) and measure the input power at the ports. Optical levels should operate about 3dBm greater than minimum levels to provide extra link margin.
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 inputport. This can be caused by incorrect data rate (for example, 10/100 Mbps), poorsignal quality (excessive jitter), or by a component failure.

Loopback Troubleshooting

The following steps describe the loopback procedure for the SummitGbx, starting on the end of the link near you. The entire procedure can also be reversed, to start with the SummitGbX on the remote end of the link. Clean optical connectors before everyconnection.

Use one of these methods to verify the outcome of loopback troubleshooting steps:
1. The terminal screen, if you are using a serial connection.
2. The GUI, if you are using the GUI software.
3. The front panel LEDs of the SummitGbX.

Using multimode fiber jumper(s), connect the Host�s GBE TX and RX ports.
Reconnect the Host�s GBE ports to the SummitGbX GBE port. Verify GBE LoopBack Enabled status. The GBE Loop Back LED should be yellow.
Using the management interface, disable GBE Loopback. Verify Loopback Disabled status. The GBE Loop Back LED should be green. Connect the SummitGbX LDI TXoutput to its LDI RX input using single mode fiber (an optical in-line attenuator is required for 80 km version only.) Verify optical power at RX.
Reconnect the SummitGbX LDI ports to the optical plant. Using the managementinterface of the remote SummitGbX, enable LDI Loopback. Verify Loopback Enabled status. The LDI Loop Back LED should be yellow.
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 usingmultimode fiber.
Using multimode fiber jumper(s), connect the remote Host�s GBE TX and RX ports. SummitGbX inputs and outputs are susceptible to damage through electro-staticdischarge (ESD). Always use ESD control measures when operating the unit.
