Chapter SGE2000/SGE2000P Gigabit Ethernet Switch Reference Guide 17 • Cable length - Displays the cable length. • Channel - Displays the cable's channel. • Polarity - Automatic polarity detection and correction permits on all RJ-45 ports for automatic adjustment of wiring errors. • Pair Skew - Reaction or transmission time in nanoseconds for the selected cable pair and given cable length. 3. Define the relevant fields. 4. Click Apply. The advanced copper cable settings are defined, and the device is updated. Performing Optical Tests The Optical Test Page allows network managers to perform tests on Fiber Optic cables. Optical transceiver diagnostics can be performed only when the link is present. During the port test, the port moves to a down state. Optical Test Page The Optical Test Page contains the following fields: • Port - Displays the port IP address on which the cable is tested. • Temperature - Displays the temperature (C) at which the cable is operating. • Voltage - Displays the voltage at which the cable is operating.
