Issue with Cisco Catalyst 4948-10GE fiber connection not functioning.
What transceiver is built into the switch? The voltage seems unusual, but the TX and RX power appear normal from my end. From your switch: Spoiler sh indicates TE1/1/1 transceiver, ITU channel not available (wavelength unavailable), transceiver self-calibrates. If it was calibrated externally, only calibrated data is shown. ++ signals high alarm, + signals high warning, - signals low warning, -- signals low alarm. NA or N/A applies; TX transmits, Rx receives. mA measures milliamperes, dBm shows decibels (milliwatts). Optical optical temperature, voltage, current, TX power, Rx power, port temp in Celsius, voltage in volts, current in mA, dBm values.
